Hawaii Mapping Research Group (HMRG) Bathymetry/Sidescan-formatted processed data files. All of the data files in this data set contain corrected towfish navigation (base file name extension = -dasc). These data files were generated by the Hawaii Mapping Research Group. A TAR bundle containing all raw, processed and derived data sets for the IMI30 system from this cruise is available upon request.

Hawaii Mapping Research Group (HMRG) Bathymetry/Sidescan-formatted processed data files. Ping headers contain an IGRF magnetic reference field correction and a towfish compass correction. File name extension = -dascc. These data files contain the same corrected towfish navigation as the precursor "dasc" files and were generated by the Hawaii Mapping Research Group. A TAR bundle containing all raw, processed and derived data sets for the IMI30 system from this cruise is available upon request.

Details
Hawaii Mapping Research Group (HMRG) Bathymetry/Sidescan-formatted processed data files. The port-side array was flooded during days-of-year 299 and 300 resulting in lower sidescan intensity values. In this set of data files, sidescan intensity values for those days, plus the following two days, have been adjusted during processing to improve consistency. File name extension = -dascs. These data files contain the same corrected towfish navigation as the precursor "dasc" files and were generated by the Hawaii Mapping Research Group. A TAR bundle containing all raw, processed and derived data sets for the IMI30 system from this cruise is available upon request.
