#### Description

Fishing effort, measured in hours of inferred fishing activity. Each asset
is the effort for a given flag state and day, with one band for the
fishing activity of each gear type.

See [sample Earth Engine
scripts](https://globalfishingwatch.org/research/global-footprint-of-fisheries/).
Also see [the main GFW site](https://GlobalFishingWatch.org) for program
information, fully interactive visualization maps, and impacts.
