This application uses a subset of the ArcView interface standard button set. Additional buttons/tools have been developed for specific functions. To obtain a more detailed description of the various button/tool functions see the Arc Buttons documention.

The DESC description tool displays images stored in the .pdf format. If your browser does not have the plug-ins to automatically display these files you may download and display or convert them locally.

While you can select sample sites for a particular cruise, it may be easier to see where a particular cruise sampled. Charts have been pre-generated for each cruise and leg. These are stored in .GIF format and can be viewed by navigating to the Cruises directory. The files are identified by SHIP_CRUISE_LEG convention. (The SHIP abbreviation codes may be found in the Ship table).

Seafloor sediment thickness has been provided courtesy of Dr. David Divens, NOAA National Geophysical Data Center (NGDC), Marine Geology and Geophysics Division. The thickness are measured in meters and the scale bar is not in uniform divisions but almost logarithmic. A complete description of the data collection may be found at the NGDC web site.
