The ability to narrow a search area is one of several critical requirements for the successful and effective detection of DFG at sea. Because the conditions that may affect the concentration and movement of marine debris, and thus where DFG may be readily found, are in constant flux, models are needed to help predict these locations a priori to optimize the search area. The strategy outlined here entails tiered investigations, research and development, and integration of the disciplines of oceanography and remote sensing with an understanding of fishing gear types and loss related to the concentration and movement of DFG.
