EK60 Water Column Sonar Data Collected During SE1002

Metadata Updated: September 17, 2021

Marine Resource Survey in waters surrounding Guam and the Commonwealth of the Northern Mariana Islands (SE1002, EK60). The goals of the cruise were to collect a variety of data to assess the status of marine resources in waters surrounding Guam and CNMI. Marine resource habitats were mapped using a Reson 8101ER multiubeam sonar operating at 240 kHz frequency. Seabed was characterized by still and video recordings using a SeaBED AUV and a Towed Optical Assessment Device (TOAD). Biological backscatter were recorded using an EK60 echosounder system operating at 38, 70, and 120 kHz along predetermined transects. Fish were sampled by Baited Remote Underwater Video Stations (BRUVS) and BotCam drops equipped with stereo cameras at predetermined locations. During the survey, a High-frequency Acoustic Recording Package (HARP) was deployed at 15° 18.998'N 145°27.542'E.
