<br><p>
Hi-res bathymetry data for SW06<br>
This data is not directly from SW06 Experiment, but from previous explorations in the area.<br>
<ul>
<a href="njos_comp_dtm.grd">njos_comp_dtm.grd</a> -
GMT-format (i.e., netcdf) binary bathymetry grid, ~50 m grid spacing <br>
<a href="njos_comp_dtm.xyz.gz">njos_comp_dtm.xyz.gz</a> -
gzipped xyz values (lon,lat,depth) from the binary bathymetry grid <br>
<a href="njos_comp_dtm.xyz">njos_comp_dtm.xyz</a> -
unzipped xyz values (lon,lat,depth) in ascii format (large file!). <br>
<a href="njos_comp_mos.grd">njos_comp_mos.grd </a>-
GMT-format (i.e., netcdf) binary backscatter mosaic grid, ~50 m grid spacing <br>
<a href="njos_comp_mos.xyz.gz">njos_comp_mos.xyz.gz</a> -
gzipped xyz values (lon,lat,depth) from the binary backscatter grid <br>
</ul><br>
Some software to read that data
<ul>
<a href="loadgridmayer2.m">loadgridmayer2.m</a> (one version)<br>
<a href="loadgridmayergridN.m">loadgridmayergridN.m</a> (another version)<br>
<a href="njos.mat">Ready .mat file</a> for loading into Matlab with sample
<a href="plot_bathym.m">plotting software</a><br>
</ul><br>
Bathymetry are a compilation of (1) STRATAFORM multibeam, (2) unpublished R/V Henlopen
swath bathymetry (which covers the landward<br> extension of the SW06 dip line) and (3) NGDC
archive data over the entire region. The multibeam data take precedence over the NGDC data.<p>
Backscatter data are a compilation of the first two sources listed above. <p>
The primary reference for the STRATAFORM data is:<p>
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<br>
and ribbon morphology in the offshore environment of the New Jersey Margin",
Marine Geology, v. 161, pp. 309-339. <p>
Excell spreadsheet <a href="Goff_etal_2004_Table1.xls">table of seafloor properties</a>
from the 2004 paper, as well as the <a href="njsedprops_reprint.pdf">pdf of the paper itself</a> (which explains
everything in the table).
