NCCOS Caribbean Fishery Acoustic Assessment: Fish Density Data Collection from NOAA Ship Nancy Foster, from 2008-03-26 to 2014-05-31 (NCEI Accession 0156395)

NOAA/NCCOS collected these data sets to help characterize broad-scale fish abundance, biomass, and understand temporal behavior. Acoustic data was collected aboard NOAA Ship Nancy Foster using 120-7C splitbeam transducer during cruise # NF08-01, NF09-01, NF10-03, NF11-01, NF12-01, NF13-01, and NF14-01.

The hull mounted Simrad 120-7C transducer was calibrated to factory standards and environmental parameters where applied during acquisition. Data was collected using 128 microsecond pulse length and had a varied ping rate due to triggering from Reson 7125 multibeam system. The resulting data layers show geo-referenced fish densities per 100 square meter intervals.
