This side scan sonar image of the sea floor was mosaiced from data collected in August 2004 onboard the NOAA vesselTatoosh. An EG&G 272 side scan system was used for geophysical surveying using 100Khz data. A Trimble DSM212Ldifferential GPS was used for positioning. Navigation from the GPS were logged in Hypack version 2.6 (CoastalOceanographics). Isis Sonar (Triton Imaging International) was used to log the sonar packets and cable counter data.Sonar data were captured using at an 112m range scale setting.

This multibeam backscatter sonar image of the sea floor (0-200 m water depths) was mosaiced from data collected fromvarious mapping efforts each October from 2001-2004. Reson 8101 (240 kHz) and Reson 8125 (455kHz) multibeam echosounders werehull mounted to survey launches and deployed from the NOAA ship Rainier. Either Trimble or CSI wireless DGPS were used forlaunch positioning. TSS or Applanix Pos/MV were used to compensate for vessel motion. A Seabird SVP 19 plus was used to correctfor sound velocity refraction. Navigation and line planning were accomplished with Hypack.

This side scan sonar imagery of the sea floor (140-350 m water depths) was mosaiced from acoustic data collected in 2005 aboard the NOAA ship McArthurII. A Klein System 3000 dual frequency side scan system was used for geophysical surveying, using only the 100Khz data to create the mosaic. A Trimble DSM212Ldifferential GPS was used for towfish positioning. Navigation from the GPS was logged in Hypack Max. Isis Sonar (Triton Imaging International) was used to log the digital sonar packets and cable counter data. Sonar data were captured using the 300m range scale setting.
