Summary

Short Citation
Office of National Marine Sanctuaries, 2024: Olympic Coast National Marine Sanctuary - mos120_0602a - Side scan sonar mosaic from survey effort 120_0602, https://www.fisheries.noaa.gov/inport/item/40104.

Abstract

This side scan sonar imagery of the sea floor (35-55 m water depths) was mosaiced from acoustic data collected in 2006 aboard the R/V Tatoosh. 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 150m range scale setting.

Data Quality

Horizontal Positional Accuracy:

Accuracy of the horizontal coordinates is on the order of 10-30m based on the uncertainty in position of side scan sonar towfish relative to ships gps position. Horizontal layback is more accurate than lateral offsets since any lateral offset in the towfish position (due to side currents)is unaccounted for in the layback calculations.

Completeness Report:

Unknown

Conceptual Consistency:

Not Tested
