Designed experiments and passive observations of DFG movement are needed to increase our overall understanding of the characteristics and behavior of DFG; tagging and telemetry combine
aspects of both and could be applied profitably to identified knowledge gaps. Because much DFG in the North Pacific, with the exception of buoys and floats, has been observed to be submerged
(authors, personal observation) the direct action of wind on DFG movement may be primarily realized in the action of surface currents.
