2. Proposed revision to the estimation of fisheries footprints

   Abstract:  A revised approach to the estimation of longline fisheries footprints is presented. The ... method uses a data-derived estimate of the uncertainty around the locations of longlines to define a ... grid. The proportion of the area of each grid cell that is covered by buffered lines is then used as a ... footprint index.
