Ocean Acre 11: A Report of the Cruise with Some Preliminary Observations.

Abstract

The eleventh Ocean Acre Cruise occurred between 9-22 January 1971, aboard USNS SANDS (T-AGOR-6). The objectives of the cruise were to: continue seasonal collections of biological organisms throughout the water column to a depth of 1500 meters, take measurements of scattering strengths of the water column at three frequencies (3.85, 13.5 and 15.5 kHz), and take associated hydrographical data. The information obtained is part of the Ocean Acre program designed to investigate the acoustics and biology of volume reverberation.
