| 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, & 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. |
