Not all AIS (Automatic Identification System) messages broadcast by vessels are picked up by receivers. This can happen for several technical reasons:
Because of this, it is not unusual to see gaps in AIS data lasting hours, or even days.
Other reasons for AIS gaps include:
Detecting these gaps is an important first step to identify possible intentional disabling events, which can obscure illegal activities, such as unauthorized fishing or transshipments.
This layer shows vessels detected using optical satellite imagery collected by the European Space Agency's Planet satellites. Optical imagery is similar to high-quality aerial photography from space, using reflected sunlight in visible and near-infrared wavelengths. This type of imagery provides high-resolution detail that allows us to spot small vessels, identify wake patterns, and better understand activity near shore.
Global Fishing Watch uses a machine learning model that processes each image to identify vessels and estimate their length, orientation, and speed based on wake features. The detections are then filtered using a secondary classifier to remove objects that are not vessels, such as clouds, rocks or icebergs. Each detection is linked to a cropped image (a thumbnail) so users can visually inspect what the model identified.
Because optical satellites rely on sunlight and clear skies, detections are only possible during the day and when the area is not obscured by clouds or haze. Despite these limitations, detections with optical imagery are especially helpful in identifying small untracked vessels that may not appear in other tracking systems.
This layer is based on images from the Planet satellites operated by the European Space Agency (ESA). These satellites capture medium-resolution images (10 m per pixel) of the ocean using visible and near-infrared light (among several other bands). Combined, the satellites acquire images of most coastal waters and dedicated areas in the open ocean roughly every five days, and the imagery is made freely available by the ESA.
We use pre-processed Planet images that have been corrected for geometric distortions and aligned to the Earth's surface. These images are split into manageable tiles, and we selected the tiles that cover only ocean areas (image tiles over land are excluded). We use four image bands: red, green, blue (RGB), and near-infrared (NIR), all at 10-meter resolution. These bands give us the detail and contrast needed to detect and classify vessels.
Our machine learning model scans each image tile to detect vessels. It is trained to look for features such as the shape, brightness, and wake of a vessel. When it finds a likely candidate, the model predicts a score for vessel presence alongside estimates of the vessel's location, size, orientation, and speed.
The detection model was trained on over 11,000 manually reviewed vessel examples across thousands of Planet scenes. This training process included many small vessels and scenes from around the world, helping the model to perform well across different environments and vessel types.
Each detection includes a small visual \"chip\" showing the detected vessel at the center. These thumbnails come in two formats: a color version from the RGB bands, and a grayscale version from the near-infrared band. Each chip covers an area of 1 km². These thumbnails are helpful for visually confirming a detection or understanding its context. For very small vessels (under 15 meters), it may still be difficult to see them clearly.
Not everything that looks like a vessel in satellite imagery actually is one. To help remove false detections (like buoys, offshore platforms, sea ice, or clouds), we run each detection through a secondary classifier. This classifier is a machine learning model that uses both the image thumbnail and additional information about the detection (such as distance from shore, local depth, and vessel density nearby, among others) to decide whether the object is likely to be a vessel. We also flag detections that are close to known fixed infrastructure or in areas with substantial sea ice or iceberg presence.
If a detection is classified as likely non-vessel or flagged as potential infrastructure or ice, we remove it from the map layer so only high-confidence detections are included. We also clip the satellite footprints (displayed on the map layer) to exclude the areas under the icy-region mask. However, we provide all the false positives with labels through the data download portal for stakeholders who require a more complete dataset.
AIS data can reveal the identity of vessels, their owners and corporations, and fishing activity. Not all vessels, however, are required to use AIS devices, as regulations vary by country, vessel size, and activity. Vessels engaged in illicit activities can also turn off their AIS transponders or manipulate the locations they broadcast. Also, large \"blind spots\" along coastal waters arise from nations that restrict access to AIS data that are captured by terrestrial receptors instead of satellites or from poor reception due to high vessel density and low-quality AIS devices. Unmatched imagery detections therefore provide the missing information about vessel traffic in the ocean.
Matching imagery detections to vessels' GPS coordinates from AIS is challenging because the timestamps of the images and AIS records do not coincide, and a single AIS identity can potentially match to multiple vessels appearing in the image, and vice versa. To determine the likelihood that a vessel broadcasting AIS corresponded to a specific detection, we developed a matching approach based on probability rasters of where a vessel is likely to be minutes before and after an AIS position was recorded. These rasters were produced from one year of global AIS data from the Global Fishing Watch pipeline, which sources satellite data from Spire Global and Orbcomm. The probability rasters are based on roughly 10 billion vessel positions and are computed for six different vessel classes, considering six different speeds and 36 time intervals. So we obtain the likely position of a vessel that could match a detection based on the vessel class, speed and time interval. In addition to the spatiotemporal matching, we factor in the similarity between the model-inferred vessel length and the length from AIS identity data to avoid (likely incorrect) matches with large discrepancies in size, e.g., AIS of a tugboat and the detection of a large vessel behind it.
To help users understand where detections were possible, we show the detection \"footprints\" on the map. These polygons are the portions of the satellite images that cover the ocean and that were used for detection. Thus, if you see a footprint but no detections, it means no vessels were detected in that area. If there is no footprint, no image was processed for that location and time.
Our detection and matching system runs automatically each day. It checks for new Planet images published to Google Cloud and processes those that meet our quality criteria. New detections are typically available within 1–2 days of the satellite capturing the image. The automated pipeline also re-checks any images published late to ensure any data gaps are filled.

These gaps are visible as part of the Gaps layer on the map, as well as in individual vessel profiles. It is important to note that not all gaps indicate a vessel has deliberately turned off its VMS device - gaps can also result from broader data anomalies such as fleet-wide outages. We are working on better ways to distinguish genuine transmission gaps from wider data provider issues.
Encounter events identify instances where two vessels appear to meet at sea. Our VMS Encounter dataset is currently experimental, and we calculate these events across all VMS sources. Because VMS predominantly tracks fishing vessels, encounters in this dataset are more likely to reflect fishing-related activity - such as pair fishing - than transshipment-related activity, which is more commonly observed in AIS data.
Global Fishing Watch classifies an event as an encounter when two vessels are detected:
The Port Visits VMS dataset detects vessel movements in and out of ports. To identify these, we use a combined anchorage list derived from our AIS dataset, supplemented by smaller ports - not captured in AIS - that were shared by our country partners. If you believe a port in your country is missing from this dataset, please do not hesitate to reach out to our support team at support@globalfishingwatch.org.
A port visit is shown on the map when VMS data shows a vessel:
Port stops are used to distinguish actual port visits from coastal transits.
Vessel Monitoring System (VMS) data for Brazil is collected via satellite and provided through a partnership with Brazil's Ministry of Fisheries and Aquaculture (MPA). The data is published with a 3-day delay, and historical data is available from 2016 onward. The polling rate depends on vessel type: drifting longline vessels report approximately every 20 minutes, while other vessels report about once per hour.
Please note that given the lower polling rates of some vessel types compared to AIS, estimates for apparent fishing activity may be less accurate. We are currently improving our fishing models to be better suited to VMS data.
In our Brazil VMS dataset, you can filter vessels by various gear types as well as by their target species.
Vessel names are visible to public users, and vessel tracks can be viewed but not downloaded. If you require data access beyond what is publicly available, please contact our support team to request access to a private workspace at support@globalfishingwatch.org.
If you notice missing data on the map, it may be due to a VMS data outage. We are currently working on better ways to communicate these outages clearly within the platform. If you have any questions regarding gaps in data, again, please do not hesitate to reach out to our support email.

Vessel Monitoring System (VMS) data for Montenegro is provided by the Ministry of Agriculture, Forestry and Water Management of Montenegro. The data is collected via satellite and includes information on vessels' identity, location, speed, and course. It is published with a 3-day delay, and historical data is available from 2024 onward.
Please note that given the lower polling rates of VMS compared to AIS, estimates for apparent fishing activity may be less accurate. We are currently improving our fishing models to be better suited to VMS data.
Vessel names and tracks are visible to public users, but tracks cannot be downloaded. If you require data access beyond what is publicly available, please contact our support team at support@globalfishingwatch.org.
If you notice missing data on the map, it may be due to a VMS data outage. We are currently working on better ways to communicate these outages clearly within the platform. If you have any questions regarding gaps in data, please do not hesitate to reach out to our support email.

EBSAs included in the CBD EBSA repository undergo formal review and adoption by the CBD COP.
\nThese areas can vary greatly in size and location, ranging from coastal waters to the high seas and from the ocean surface to the seabed. EBSAs encompass a wide range of species, habitats and oceanographic features, including dynamic and ephemeral phenomena, as well as areas that are important seasonally or throughout the year. EBSAs have included features such as seamounts, hydrothermal vents, coral reefs, migratory corridors, seasonal fish spawning areas and coastal upwellings, among many other types of ecosystems.

Classification labels (oil, wind, and unknown) are provided, as well as confidence levels (high, medium, or low) reflecting our certainty in the assigned label. Detections can be filtered and colored on the map using both label and confidence level.The data is updated on a monthly basis, and new classified detections are added at the beginning of every month. Viewing change using the timebar is simple, and allows anyone to recognize the rapid industrialization of the world’s oceans. For example, you can easily observe the expansion of wind farms in the North and East China Seas, or changes in oil infrastructure in the Gulf of Mexico or Persian Gulf.
By overlaying the existing map layers, you can explore how vessels interact with oil and wind structures, visualise the density of synthetic aperture radar (SAR) and Visible Infrared Imaging Radiometer Suite (VIIRS) vessel detections around infrastructure, or determine which marine protected areas (MPAs) contain wind, oil, or other infrastructure types. These are only examples of the types of questions we can now ask. Offshore fixed infrastructure is a first of its kind dataset that not only brings to light the extensive industrialization of our oceans, but enables users across industries to use this information in research, monitoring and management.
We use SAR imagery from the Copernicus Sentinel-1 mission of the European Space Agency (ESA) [1]. The images are sourced from two satellites (S1A and S1B up until December 2021 when S1B stopped operating, and S1A only from 2022 onward) that orbit 180 degrees out of phase with each other in a polar, sun-synchronous orbit. Each satellite has a repeat-cycle of 12 days, so that together they provide a global mapping of coastal waters around the world approximately every six days for the period that both were operating. The number of images per location, however, varies greatly depending on mission priorities, latitude, and degree of overlap between adjacent satellite passes. Spatial coverage also varies over time [2]. Our data consist of dual-polarization images (VH and VV) from the Interferometric Wide (IW) swath mode, with a resolution of about 20 m.

Detecting infrastructure with SAR is based on the widely used Constant False Alarm Rate (CFAR) algorithm, an anomaly detection method conceived for detecting ships in synthetic aperture radar images, that has been modified to remove non-stationary objects. This algorithm is designed to search for pixel values that are unusually bright (the targets) compared to those in the surrounding area (the sea clutter). This method sets a threshold based on the pixel values of the local background (within a window), scanning the whole image pixel-by-pixel. Pixel values above the threshold constitute an anomaly and are likely to be samples from a target.
To classify every detected offshore infrastructure, we used deep learning and designed a ConvNet based on the ConvNeXt architecture. A novel aspect of our deep learning classification approach is the combination of SAR imagery from Sentinel-1 with optical imagery from Sentinel-2. From six-month composites of dual-band SAR (VH and VV) and four-band optical (RGB and NIR) images, we extracted small tiles for every detected fixed infrastructure, with the respective objects at the center of the tile. A single model output includes the probabilities for the specified classes: wind, oil, unknown, lake maracaibo, and noise.
GFW post-processed the classified SAR detections to reduce noise (false positives), remove vessels, exclude areas with sea ice at high latitudes, and incorporate expert feedback. We used a clustering approach to identify detections across time (within a 50 m radius) that were likely the same structure but their coordinates differed slightly, and assigned them the greatest average predicted label of the cluster. We also filled in gaps for fixed structures that were missing in one timestep but detected in the previous and following timesteps, and dropped detections appearing in a single timestep. Finally, the dataset underwent extensive manual review and editing by researchers and industry experts in order to refine the final product, and provide the most accurate dataset possible.
Each detection has a unique individual identifier (detection_id). A six-month image composite is used in the classification, therefore the detection_date represents the middle of the six month period. This helps to remove non-stationary objects (i.e. vessels), and avoid confusion in the model if a structure is being built, or there isn’t adequate imagery available. structure_id allows you to track a structure through time. There are therefore many detection_id (one for each month the structure is detected) for each structure_id. Labels of wind and oil represent any wind or oil related structure respectively. Unknown represents a structure that is not oil or wind related, such as bridges or navigational buoys.
Label confidence levels of ‘High’. ‘Medium’ and ‘Low’ are assigned to each structure, and are conditional on where the detections fell in relation to the boundaries of manually developed wind and oil polygons, and whether the label has changed from the previous month. The label_confidence field can be used to filter analysis.

The SAR image contains rich information about the different objects on the water, such as their size, orientation and texture. SAR imaging systems overcome most weather conditions and illumination levels, including clouds or rain due to the cloud penetrating property of microwaves, and daylight or darkness due to radar being an “active” sensor (it shoots and records back its own energy). SAR gives an advantage over some other “passive” satellite sensors, such as electro-optical imagery, consisting of a satellite-based camera recording the sunlight/infrared radiation reflected from/emitted by objects on the ground. This latter method can be confounded by cloud cover, haze, weather events and seasonal darkness at high latitudes.
\nWe use SAR imagery from the Copernicus Sentinel-1 mission of the European Space Agency (ESA) [1]. The images are sourced from two satellites (S1A and S1B up until December 2021 when S1B stopped operating, and S1A only from 2022 onward) that orbit 180 degrees out of phase with each other in a polar, sun-synchronous orbit. Each satellite has a repeat-cycle of 12 days, so that together they provide a global mapping of coastal waters around the world approximately every six days for the period that both were operating. The number of images per location, however, varies greatly depending on mission priorities, latitude, and degree of overlap between adjacent satellite passes. Spatial coverage also varies over time [2]. Our data consist of dual-polarization images (VH and VV) from the Interferometric Wide (IW) swath mode, with a resolution of about 20 m.

\nDetection footprints are areas within each satellite scan (or scene) that our system uses to perform detections. These filters help to keep relevant detections and exclude data that may be inaccurate. Detection footprints are smaller than the total scene as they exclude any land areas and islands, and exclude a 500 meter buffer from the boundaries of the scene and a 1 kilometer buffer from shorelines.
\nGFW has post-processed the SAR detections to reduce noise (false positives), remove offshore infrastructure from this layer focused on vessels, and exclude areas with sea ice at high latitudes.
\nDetecting vessels with SAR is based on an known as Constant False Alarm Rate (CFAR), a threshold algorithm used for anomaly detection in radar imagery. This algorithm is designed to search for pixel values that are unusually bright (the targets) compared to those in the surrounding area (the sea clutter). This method sets a threshold based on the pixel values of the local background (within a window), scanning the whole image pixel-by-pixel. Pixel values above the threshold constitute an anomaly and are likely to be samples from a target, and therefore are included as a detection.
\nTo estimate the length of every detected object and also to identify when our CFAR algorithm made false detections, we designed a deep convolutional neural network (ConvNet) based on the modern ResNet (Residual Networks) architecture. This single-input/multi-output ConvNet takes dual-band SAR image tiles of 80 by 80 pixels as input, and outputs the probability of object presence (known as a “binary classification task”) and the estimated length of the object (known as a “regression task”).
\nTo identify whether a detected vessel was a fishing or non-fishing vessel we use a machine learning model. For this classification task we used a ConvNeXt architecture modified to process the following two inputs: the estimated length of the vessel from SAR (a scalar quantity) and a stack of environmental rasters centered at the vessel’s location (a multi-channel image). This multi-input-mixed-data/single-output model passes the raster stack (11 channels) through a series of convolutional layers and combines the resulting feature maps with the vessel length value to perform a binary classification: fishing or non-fishing.
\nThe environmental layers used to differentiate between fishing and non-fishing include:
\nAIS data can reveal the identity of vessels, their owners and corporations, and fishing activity. Not all vessels, however, are required to use AIS devices, as regulations vary by country, vessel size, and activity. Vessels engaged in illicit activities can also turn off their AIS transponders or manipulate the locations they broadcast. Also, large “blind spots” along coastal waters arise from nations that restrict access to AIS data that are captured by terrestrial receptors instead of satellites or from poor reception due to high vessel density and low-quality AIS devices. Unmatched SAR detections therefore provide the missing information about vessel traffic in the ocean.
\nMatching SAR detections to vessels’ GPS coordinates (from the automatic identification system (AIS) is challenging because the timestamp of the SAR images and AIS records do not coincide, and a single AIS message can potentially match to multiple vessels appearing in the image, and vice versa. To determine the likelihood that a vessel broadcasting AIS corresponded to a specific SAR detection, we followed a matching approach based on probability rasters of where a vessel is likely to be minutes before and after an AIS position was recorded. These rasters were developed from one year of global AIS data from the Global Fishing Watch pipeline which uses Spire Global and Orbcomm sources of satellite data, including roughly 10 billion vessel positions, and computed for six different vessel classes, considering six different speeds and 36 time intervals. So we obtain the likely position of a vessel that could match a SAR detection based on the vessel class, speed and time interval.

Esta camada mostra embarcações detectadas por meio de imagens ópticas de satélite coletadas pelos satélites Sentinel-2 da Agência Espacial Europeia. Imagens ópticas são semelhantes a fotografias aéreas de alta qualidade tiradas do espaço, usando a luz solar refletida em comprimentos de onda visíveis infravermelhos próximos. Esse tipo de imagem fornece detalhes em alta resolução que nos permitem localizar pequenas embarcações, identificar padrões de esteira e entender melhor as atividades próximas à costa.
\nA Global Fishing Watch utiliza um modelo de aprendizado de máquina que processa cada imagem para identificar embarcações e estimar seu comprimento, orientação e velocidade com base nas características da esteira. As detecções são então filtradas com um classificador secundário para a remoção de objetos que não são embarcações, como nuvens, rochas ou icebergs. Cada detecção é vinculada a uma imagem recortada (uma miniatura) para que os usuários possam inspecionar visualmente o que o modelo identificou.
\nComo os satélites ópticos dependem da luz solar e do céu limpo, as detecções só são possíveis durante o dia e quando a área não está obscurecida por nuvens ou neblina. Apesar dessas limitações, as detecções com imagens ópticas são muito úteis para identificar pequenas embarcações não rastreadas que podem não aparecer em outros sistemas de rastreamento.
\nEssa camada é baseada em imagens dos satélites Sentinel-2 operados pela Agência Espacial Europeia (ESA). Esses satélites capturam imagens de média resolução (10 m por pixel) do oceano usando luz visível e infravermelha próxima (entre várias outras bandas). Combinados, os satélites adquirem imagens da maioria das águas costeiras e áreas dedicadas no oceano aberto aproximadamente a cada cinco dias, e as imagens são disponibilizadas gratuitamente pela ESA.
\nUsamos imagens pré-processadas do Sentinel-2 que foram corrigidas para distorções geométricas e alinhadas à superfície da Terra. Essas imagens são divididas em blocos gerenciáveis, e nós selecionamos os blocos que cobrem apenas áreas oceânicas (blocos de imagens sobre áreas terrestres são excluídos). Utilizamos quatro bandas de imagem: vermelho, verde, azul (RGB) e infravermelho próximo (NIR), todas com resolução de 10 metros. Essas bandas nos fornecem os detalhes e o contraste necessários para detectar e classificar as embarcações.
\nNosso modelo de aprendizado de máquina escaneia cada bloco de imagem para detectar as embarcações. Ele é treinado para buscar características como o formato, o brilho e a esteira de uma embarcação. Quando encontra uma possível candidata, o modelo prevê uma pontuação para a presença da embarcação, juntamente com estimativas da localização, tamanho, orientação e velocidade da embarcação.
\nO modelo de detecção foi treinado em mais de 11.000 exemplos de embarcações revisados manualmente em milhares de cenas do Sentinel-2. Esse processo de treinamento incluiu muitas pequenas embarcações e cenas do mundo todo, ajudando o modelo a apresentar um bom desempenho em diferentes ambientes e tipos de embarcações.
\nCada detecção inclui um pequeno “recorte” visual mostrando a embarcação detectada ao centro. Essas miniaturas estão disponíveis em dois formatos: uma versão colorida a partir das bandas RGB e uma versão em tons de cinza a partir da banda do infravermelho próximo. Cada chip cobre uma área de 1 km². Essas miniaturas são úteis para confirmar visualmente uma detecção ou entender seu contexto. Para embarcações muito pequenas (com menos de 15 metros), ainda pode ser difícil vê-las claramente.
\nNem tudo que parece uma embarcação em imagens de satélite realmente é. Para ajudar a remover detecções falsas (como boias, plataformas offshore, gelo marinho ou nuvens), executamos cada detecção por meio de um classificador secundário. Esse classificador é um modelo de aprendizado de máquina que usa tanto a miniatura da imagem quanto informações adicionais sobre a detecção (como distância da costa, profundidade local e densidade de embarcações próximas) para decidir se o objeto é provavelmente uma embarcação. Nós também sinalizamos detecções próximas a infraestruturas fixas conhecidas ou em áreas com presença considerável de gelo marinho ou icebergs.
\nSe uma detecção for classificada como provavelmente não relacionada a embarcações ou sinalizada como uma possível infraestrutura ou gelo, nós a removemos da camada do mapa para que apenas detecções de alta confiança sejam incluídas. Também recortamos as pegadas de satélite exibidas na camada do mapa para excluir as áreas sob a máscara de área gelada. No entanto, fornecemos todos os falsos positivos com rótulos por meio do portal de download de dados para as partes interessadas que exigem um conjunto de dados mais completo.
\nOs dados do AIS podem revelar a identidade das embarcações, de seus proprietários e corporações, bem como atividades de pesca. No entanto, nem todas as embarcações são obrigadas a usar dispositivos AIS, já que as regulamentações variam de acordo com o país, o tamanho da embarcação e a atividade. Embarcações envolvidas em atividades ilícitas também podem desligar seus transponders AIS ou podem manipular os locais que transmitem. Além disso, grandes “pontos cegos” ao longo das águas costeiras surgem de nações que restringem o acesso a dados do AIS capturados por receptores terrestres em vez de satélites ou de recepção ruim devido à alta densidade de embarcações e dispositivos AIS de baixa qualidade. As detecções de imagens não correspondentes fornecem, portanto, as informações que faltam sobre o tráfego de embarcações no oceano.
\nA correspondência entre as detecções de imagens e as coordenadas por GPS das embarcações do AIS é desafiadora porque o registro de data e hora das imagens e dos registros do AIS não coincidem, e uma única identidade do AIS pode potencialmente corresponder a várias embarcações que aparecem na imagem, e vice-versa. Para determinar a probabilidade de uma embarcação transmitindo AIS corresponder a uma detecção específica, desenvolvemos uma abordagem de correspondência baseada em rasters de probabilidade de onde uma embarcação provavelmente estaria minutos antes e depois de uma posição do AIS ser registrada. Esses rasters foram produzidos a partir de um ano de dados globais do AIS provenientes do pipeline da Global Fishing Watch, que obtém dados de satélite da Spire Global e da Orbcomm. Os rasters de probabilidade são baseados em aproximadamente 10 bilhões de posições de embarcações e são computados para seis classes diferentes de embarcações, considerando seis velocidades diferentes e 36 intervalos de tempo. Assim, obtemos a provável posição de uma embarcação que poderia corresponder a uma detecção com base na classe da embarcação, velocidade e intervalo de tempo. Além da correspondência espaço-temporal, levamos em conta a semelhança entre o comprimento da embarcação inferido pelo modelo e o comprimento a partir dos dados de identidade do AIS para evitar correspondências (provavelmente incorretas) com grandes discrepâncias de tamanho como, por exemplo, AIS de um rebocador e a detecção de uma grande embarcação atrás dele.
\nPara ajudar os usuários a entender onde as detecções foram possíveis, mostramos as “pegadas” de detecção no mapa. Esses polígonos são as porções das imagens de satélite que cobrem o oceano e que foram usadas para a detecção. Assim, se você vir uma pegada, mas nenhuma detecção, significa que nenhuma embarcação foi detectada na área. Se não houver pegada, nenhuma imagem será processada para determinado local e hora.
\nNosso sistema de detecção e correspondência é executado automaticamente todos os dias. Ele verifica novas imagens do Sentinel-2 publicadas no Google Cloud e processa as que atendem aos nossos critérios de qualidade. Novas detecções geralmente ficam disponíveis em 1 a 2 dias após a captura da imagem pelo satélite. O pipeline automatizado também verifica novamente quaisquer imagens publicadas tardiamente para garantir que eventuais lacunas de dados sejam preenchidas.

The MPA Guide is intended to fill a gap in existing MPA classification and assessment tools to help determine how likely MPAs are to deliver the desired conservation outcomes. Over the past few years, the MPAtlas team and key collaborators have applied The MPA Guide framework to MPAs around the world to develop a clearer picture of global marine protection, which includes a recent study establishing a baseline for global \"30x30\" targets - Publication: Ocean Protection Quality is Lagging Behind Quantity. MPAtlas is the online repository for MPA Guide assessments and associated data. Stage of Establishment represents where the MPA is in its process of being an MPA. Proposed/Committed: The intent to create an MPA is made public. Designated: MPA is established/recognized through legal means or other authoritative rulemaking. Implemented: MPA is acknowledged to be operation ‘in the water’ with plans for management activated. Actively managed: MPA management is ongoing, with monitoring, periodic review and adjustments made as needed to achieve biodiversity conservation and other ecological and social goals. Level of Protection represents the extent to which the MPA protected from seven main types of human activities and is likely to generate positive biodiversity outcomes. Fully Protected: No impact from extractive or destructive activities is allowed, and all abatable impacts are minimized. Highly Protected: Only light extractive activities are allowed that have low total impact, and all other abatable impacts are minimized. Lightly Protected: Some protection of biodiversity exists, but extractive or destructive activities that can have moderate to significant impact are allowed. Minimally Protected: Extensive extraction and other activities with high total impact are allowed, but the site can still be considered an MPA under the IUCN protected area definition and provides some conservation benefit. Some areas allow activities that have an impact so large that they are incompatible with the conservation of biodiversity, as defined by the IUCN. For more information, please visit https://mpatlas.org/. Each assessed MPA has a score card that describes its stage of establishment and level of protection, as well as more details about the components that contributed to these assessments. Note: The MPAtlas dataset does not contain boundaries for all global MPAs, only those assessed against MPA quality frameworks.

Baselines were extracted from Flanders Marine Institute’s (2023) version 12 global EEZ database, defined by ‘Straight Baseline’ features. The shoreline dataset was ESRI’s 2014 global shoreline, the same shoreline dataset as the Flanders Marine Institute global EEZ database.

Data is received by Panama’s VMS system via satellite and contains vessel identities, gear type, location, speed, direction and more. Panama’s carrier vessel data is also available here. Each point in the carrier vessel data layer represents a position of the carriers, but not all positions are displayed. Carrier vessel positions are displayed once per day. In the future, we expect to be able to display more positions. Click on a carrier vessel’s position to view the vessel’s complete track. Global Fishing Watch analyzes this data using the same algorithms we developed for automatic identification system (AIS) data to identify fishing activity and behaviors. The algorithm classifies each broadcast data point from vessels as either apparently fishing or not fishing and shows the former on the Global Fishing Watch fishing activity heat map. VMS broadcasts data quite differently from AIS and may give different measures of completeness, accuracy and quality. Over time our algorithms will improve across all our broadcast data formats. Global Fishing Watch’s fishing presence algorithm for VMS, as for AIS, is a best effort to algorithmically identify “apparent fishing activity.” It is possible that some fishing activity is not identified, or that the heat map may show apparent fishing activity where fishing is not actually taking place. For these reasons, Global Fishing Watch qualifies the terms “fishing activity,” “fishing,” and “fishing effort,” as “apparent” rather than certain. Any/all Global Fishing Watch information about “apparent fishing activity” should be considered an estimate and must be relied upon solely at your own risk. Global Fishing Watch fishing presence algorithms are developed and tested using actual fishing event data collected by observers, combined with expert analysis of AIS vessel movement data resulting in the manual classification of thousands of known fishing events.

AIS was developed for safety/collision-avoidance. Global Fishing Watch analyzes AIS data collected from vessels that our research has identified as known or possible commercial fishing vessels, and applies a fishing presence algorithm to determine “apparent fishing activity” based on changes in vessel speed and direction. The algorithm classifies each AIS broadcast data point for these vessels as either apparently fishing or not fishing and shows the former on the Global Fishing Watch fishing activity heat map. AIS data as broadcast may vary in completeness, accuracy and quality. Also, data collection by satellite or terrestrial receivers may introduce errors through missing or inaccurate data. Global Fishing Watch’s fishing presence algorithm is a best effort mathematically to identify “apparent fishing activity.” As a result, it is possible that some fishing activity is not identified as such by Global Fishing Watch; conversely, Global Fishing Watch may show apparent fishing activity where fishing is not actually taking place. For these reasons, Global Fishing Watch qualifies designations of vessel fishing activity, including synonyms of the term “fishing activity,” such as “fishing” or “fishing effort,” as “apparent,” rather than certain. Any/all Global Fishing Watch information about “apparent fishing activity” should be considered an estimate and must be relied upon solely at your own risk. Global Fishing Watch is taking steps to make sure fishing activity designations are as accurate as possible. Global Fishing Watch fishing presence algorithms are developed and tested using actual fishing event data collected by observers, combined with expert analysis of vessel movement data resulting in the manual classification of thousands of known fishing events.
