Acoustic responses to water column features, Antarctic, Aug-Sept
2002, GLOBEC.
Using the hull mounted Simrad EK500 Scientific Sounder System,
acoustic returns from 38, 120, and 200 kHz transducers were recorded
continuously along ship's track from Aug 3 - Sept 15, 2002. Of interest,
was the acoustic returns from zooplankton patches and density structures,
and the signel correlations with known plankton tows and CTD casts. The
survey area included the continental margin to the west of the Antarctic
Peninsula extending from the northern tip of Adelaide Island to the
southern portion of Alexander Island, Crystal Sound, and Marguerite Bay.
These data have been reduced to daily files and are supported by software
for manipulative purposes. Ship name/cruise ID/dates of cruise RVIB
