Background

This DVD-ROM contains copies of the multibeam bathymetry and acoustic backscatter, CTD/XBT and GPS navigation data collected aboard the NOAA ship Ron Brown during USGS Cruise 02051 in collaboration with NOAA (same Cruise RB0208)  from September 24 to September 30, 2002.  This maiden cruise initiates an on-going field program involving  the USGS Woods Hole Science Center and the NOAA Office of Ocean Exploration, to map and describe the geologic features and extent of the Puerto Rico Trench, the deepest part of the Atlantic Ocean.

On this DVD-ROM, processed data collected during the trench cruise can be viewed in 3D using the freeware application GeoZui3D from in the Data Visualization Research Lab which is a part of the Center for Coastal and Ocean Mapping at the University of New Hampshire (a NOAA collaborator) .  The field data and background data for the region is configured with ESRI Arcview GIS software and is available in shapefile format and Arcview file structures.  An ESRI Arcview project file is included for the user.

GeoZui3D Visualization and ESRI GIS

GeoZui3D Visualization

GeoZui3D is an interactive 3D visualization system developed in the Data Visualization Research Lab of the Center for Coastal and Ocean Mapping at the University of New Hampshire. It is also intended to be a practical and useful tool for fusing multiple sources of georeferenced Data.( http://www.ccom.unh.edu/vislab/GeoZui3D/)

ESRI GIS

An Environmental Systems Research Institute (ESRI) ArcView 3.x Geographic Information System (GIS) project file, prt2002.apr, resides in the arcview directory. All associated GIS files are also contained within this directory structure. The user must have a copy of ESRI ArcView 3.x in order to use the project file. Visit the ESRI Website (http://www.esri.com) for information concerning this, and other software, such as ArcExplorer, a free GIS data viewer available for download.

To Load prt2002.apr:

  • prt2002.apr contains links to all shape files referenced in this report

Projected Views:

The Puerto Rico Trench imagery was processed in the following coordinate system: UTM, WGS84 datum, Zone 19, meters.  All raster images and grids are available in both geographic (un-projected) and projected UTM, Zone 19.  All point and vector data are stored in decimal degrees.

System Requirements

This DVD-ROM can be used the following operating systems: Microsoft Windows and UNIX systems.  However, the ESRI ArcView project file, prt2002.apr, works best on Microsoft Windows operating systems using ArcView or ArcExplorer.  The GeoZui3D will run on Microsoft Windows and Unix systems
when loaded properly.
