| Abstract: |
This side scan sonar imagery of the sea floor (50-80 m water depths) was mosaiced from acoustic data collected in 2004 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 tolog the digital sonar packets and cable counter data.Sonar data were captured using the 150m range scale setting. |
| Purpose: |
These data are intended for science researchers, students, policy makers, and the general public. The data can beused with geographic information systems (GIS) software to display benthic information. |

Data Quality
| Horizontal Positional Accuracy: |
Accuracy of the horizontal coordinates is on the order of 10-30m based on theuncertainty in position of side scan sonar towfish relative to ships gps position. Horizontal layback is more accuratethan lateral offsets since any lateral offset in the towfish position (due to side currents)is unaccounted for in thelayback calculations. |
