John Goff's Bathymetry Data
Hi-res bathymetry data for SW06
This data is not directly from SW06 Experiment, but from previous explorations in the area.

njos_comp_dtm.grd - GMT-format (i.e., netcdf) binary bathymetry grid, ~50 m grid spacing
njos_comp_dtm.xyz.gz - gzipped xyz values (lon,lat,depth) from the binary bathymetry grid
njos_comp_dtm.xyz - unzipped xyz values (lon,lat,depth) in ascii format (large file!).
njos_comp_mos.grd - GMT-format (i.e., netcdf) binary backscatter mosaic grid, ~50 m grid spacing
njos_comp_mos.xyz.gz - gzipped xyz values (lon,lat,depth) from the binary backscatter grid

Some software to read that data
loadgridmayer2.m (one version)
loadgridmayergridN.m (another version)
Ready .mat file for loading into Matlab with sample plotting software

Bathymetry are a compilation of (1) STRATAFORM multibeam, (2) unpublished R/V Henlopen swath bathymetry (which covers the landward
extension of the SW06 dip line) and (3) NGDC archive data over the entire region. The multibeam data take precedence over the NGDC data.
Backscatter data are a compilation of the first two sources listed above.
The primary reference for the STRATAFORM data is:
Goff, J. A., D. J. P. Swift, C. S. Duncan, L. A. Mayer, and J. Hughes-Clarke, 1999. "High resolution swath sonar investigation of sand ridge, dune
and ribbon morphology in the offshore environment of the New Jersey Margin", Marine Geology, v. 161, pp. 309-339.
Excell spreadsheet table of seafloor properties from the 2004 paper, as well as the pdf of the paper itself (which explains everything in the table).
