Notably, humpback whales are most often found in association with highly concentrated patches of krill, and fin whales are found in association with schools of capelin. underDevelopment McCarthy, Abigail abigail.mccarthy@noaa.gov pointOfContact Towler, Rick rick.towler@noaa.gov custodian asNeeded DOC/NOAA/NMFS/AFSC > Alaska Fisheries Science Center, National Marine Fisheries Service, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2017-04-24 publication 8.5 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.

Four split-beam transducers (18, 38, 120, and 200 kHz) were mounted on the bottom of the vessel's retractable centerboard, which extended 9 m below the water surface. System electronics were housed inside the vessel in a permanent laboratory space dedicated to acoustics. Acoustic data were collected at 38 kHz with the EK500 echosounder and at 18, 120, and 200 kHz with the ER60 echosounder. Acoustic data were logged using SonarData EchoLog 500 and ER60 software. Echo integration data were collected from 14 m (45.9 ft) below the surface to 0.5 m (1.6 ft) of the bottom and were analyzed using SonarData Echoview post-processing software (Version 3.10.129). Echo integration and target strength (TS) data were collected simultaneously for all sounder-transducer combinations. Results presented here are based on 38 kHz data.
