Project PROBE Leg I - Report and Archive of Multibeam
Bathymetry and Acoustic Backscatter, CTD/XBT and GPS Navigation
Data Collected During USGS Cruise 02051 (NOAA Cruise RB0208)
Puerto Rico Trench, September 24, 2002 to September 30,
2002
The Puerto Rico Trench is a tectonic plate boundary where the North
American Plate slides by and descends under the Caribbean Plate. Although
much of the trench lies within the United States of America's Exclusive
Economic Zone (EEZ), surprisingly few surveys have been conducted
there during the past 25 years. This data set is a grey toned surface
model image product derived from a process using multibeam bathymetry
and accusic-backscatter imagery data collected during the U.S. Geological
Survey (USGS) science cruise 02051 in collaboration with the National
Oceanic and Atmospheric Administration (NOAA) Research Cruise RB0208
from 24 September to 30 September 2002, Leg I of III. (Leg II and
III: 20030218 to 20030407 and 20030828 to 20030904, respectively).
Purpose:
This multibeam bathymetric and acoustic backscatter imagery can
be used in Geographic Information Science (GIS) to provide better
perspective viewing and advanced analysis of geologic conditions in
the Puerto Rico Trench. Remotely sensed features in the trench are
studied and the information learned can be used to discern cause and
effect of natural hazards such as earthquakes and tsunamis.

Project PROBE Leg II - Final Report and Archive of Swath Bathymetric
Sonar, CTD/XBT and GPS Navigation Data Collected During USGS Cruise
03008 (NOAA Cruise RB0303) Puerto Rico Trench 18 February - 7
March, 2003
The processing of data from multibeam bathmetry and acousic backscatter started with the collection of raw data imagery that were converted using Caris 5.3 Hips Sips software. The contued processing of data entailed reviewing and editing it with Caris Swath Edit, followed with Caris Sub Set mode editing. Both editing processes allowed the hydrographer to eliminate data points that were considered artifacts or out of context with the immediate benthic area. After editing, the weighted mead grid was re-generated with a grid resolution (s) from 300 to 30 meters.

Hyphenated filed names with underscores, for example, "150m-ne.tif"
to "150m_ne.tif" were replaced. The replacement name
may allow a wider range of acceptance (interoperability) between
differing operating systems, if applicable.
