|
Summary of Field Work: |
Conduct acoustic and net surveys off Northern California and Southern Oregon. Advanced broadband acoustic systems will be used to characterize scattering and attenuation due to swimbladder-bearing fish and squid. The studies will involve transects and measurements at fixed locations. |
|
Summary of Facility Requirements: |
: CTD, flurometer, ship winches and wires (see ‘NRL Equipment Requirements’ below), capstans, GPS navigation (DGPS even better), standard comms (as there will be 2-ship coordination), 12-kHz echosounder, XBT launcher, XBT-analysis system, Dynamic positioning |
|
Summary of other requirements and comments: |
Coordination with second research vessel, Chief Scientist Benoit-Bird |
