EK60 Water Column Sonar Data Collected During OS201901

Description

To investigate the distribution, life history, and interactions of biological communities in the U.S. Continental Region of the NE Chukchi Sea, a survey was conducted from August - September 2019. Acoustic data was collected as part of an acoustic-trawl effort to classify the midwater fish community of the region. The survey was conducted along 0.75 degree spaced transect lines from 66.5N to 73N between 168.5W and 156.8W. The primary water column acoustic instrument for the survey was a Simrad EK60 scientific echosounder equipped with a Simrad ES38B 38 kHz transducer and ES120-7C 120 kHz transducer. The ship departed Dutch Harbor, AK on 01 August 2019 and began the survey in the Chukchi Sea on 27 August 2019. The survey ended in Nome, AK on 01 October 2019. The echosounder was calibrated with a 38.1 mm tungsten-carbide sphere via the standard sphere method before and after the survey.
