Nautical Area Scattering Coefficients (NASC) from R/V New Horizon cruises NH1106 and NH1006 in the Guaymas Basin in 2010 and 2011 (Jumbo Squid Physiology project)

Abstract

Integrated, area scattering values, or Natuical Area Scattering Coefficients (NASC) are provided from two cruises in the Guaymas Basin that occurred in June 2010 and June 2011. Also included are the time (UTC) and location at the start and end of each integration bin, mean depth of the exclusion line for each bin, and the average thickness of the integrated cell.

Raw acoustic scattering data (.raw files) are extremely large. These are archived at Oregon State University and will be shared using physical media upon request.

For a complete list of measurements, refer to the full dataset description in the supplemental file 'Dataset_description.pdf'. The most current version of this dataset is available at: https://www.bco-dmo.org/dataset/4013
