Fishing intensity
Global Datasets of AIS-based Fishing Effort and Vessel Presence This dataset contains the Global Fishing Watch AIS-based fishing effort and vessel presence datasets. Data is based on fishing detections of >114,000 unique AIS devices on fishing vessels, of which ~70,000 are active each year. Fishing vessels are identified via a neural network classifier, vessel registry databases, and manual review by GFW and regional experts. Data are binned into grid cells 0.01 (or 0.1) degrees on a side and measured in units of hours. The time is calculated by assigning an amount of time to each AIS detection (which is the time to the previous position), and then summing all positions in each grid cell.
Data are available in two formats:
1) Fishing effort by flag state and gear type at 100th degree resolution 2) Fishing effort by MMSI at 10th degree resolution
Each version of the fishing effort dataset is accompanied by a table of vessel information (e.g. gear type, flag state, dimensions, etc.).
