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.
