Alaska Bathymetry: Central Gulf of Alaska Multibeam Data(pg 1, 2, 3, 4, 5, 6, 7, 8, 9, 10)

Multibeam Data of Central Gulf of Alaska

There were several areas where these older smooth sheet surveys were superseded by more recent, higher quality multibeam and LIDAR surveys, mostly from the NOS. Forty-two of these NOS surveys covered a continuous area near Sitka but there were gaps where three multibeam surveys - H11114 , H11118, and H11354 - were missing. We edited and processed these three missing multibeam surveys into final surfaces. Click here for zipped multibeam data and metadata download.
