This compilation of SeaBeam 2112 data from the USCGC Healy and Simrad EM120 data from the R/V Nathaniel B Palmer is a work in progress. Data processors at the Hawaii Mapping Research Group (HMRG) have been busy attempting to clean out noise and navigation errors present within the data donated to the AAGRUUK Archive by many kind Principal Investigators. The grid, which you can download below, will be updated as the data is cleaned further. To download the "edited" multibeam files, check back here soon and an interface will be available.
