EK60 Water Column Sonar Data Collected During OS201701

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 2017. 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 0.5 degree spaced transect lines from 67N to 72N between 168.5W and 153.25W. The primary water column acoustic instrument for the survey was a Simrad EK60 scientific echosounder equipped with a Simrad ES38-B 38 kHz transducer and ES120-7C 120 kHz transducer. The ship departed Dutch Harbor, AK on 01 August 2017 and began the survey in the Chukchi Sea on 09 August 2017. The survey ended in Nome, AK on 28 September 2017. The echosounder was calibrated with a 38.1 mm tungsten-carbide sphere via the standard sphere method during installation on 24 July 2017 and again at the start of the survey on 01 August 2017.
