Title:
Fledermaus Scene combining three 150-meter bathymetry grids from U.S. Geological Survey cruises 02051, 03008 and 03032 surveyed in 2002 and 2003 in the region of the Puerto Rico Trench
Abstract:
In 2002 and 2003, the U.S. Geological Survey (USGS), Woods Hole Coastal and Marine Science Center (WHCMSC), in cooperation with the National Oceanic and Atmospheric Administration (NOAA), conducted three exploration cruises (USGS Cruise 02051, NOAA RB0208, September 24 to 30, 2002; USGS Cruise 03008, NOAA RB0303, February 18 to March 7, 2003 and USGS Cruise 03032, NOAA RB0305, August 28 to September 4, 2003). These cruises mapped for the first time the morphology of this entire tectonic plate boundary stretching from the Dominican Republic in the west to the Lesser Antilles in the east, a distance of approximately 700 kilometers (430 miles). Observations from these three exploration cruises, coupled with computer modeling and published Global Positioning System (GPS) results and earthquake focal mechanisms have provided new information that is changing the evaluation of the seismic and tsunami hazard from this plate boundary. The observations collected during these cruises also contributed to the basic understanding of the mechanisms that govern plate tectonics, in this case, the creation of the island of Puerto Rico and the deep trench north of it. Results of the sea floor mapping have been an important component of the study of tsunami and earthquake hazards to the northeastern Caribbean and the U.S. Atlantic coast off the United States.

    Source_Contribution: NGDC Etopo1 database
  2. How were the data generated, processed, and modified?
    Date: 2009 (process 1 of 4)
    The Etopo1 database at NOAA was accessed using the Design-a-Grid ( http://www.ngdc.noaa.gov/mgg/gdas/gd_designagrid.html ) selecting bounds at 30N, 5N, 100W, 50W and 1 minute cell size resulting in a 3001 col by 1501 row grid which was download as a ASCII raster with an Arc header.

    Date: Unknown (process 2 of 4)
    A combined.scene file was created by loading the three SD bathymetry grids into Fledermaus. The carib-8756.asc grid was imported with Fledermaus Ver 7, the Geo-Referencing tab was selected to convert the carib-8756 grid from wgs84 geographic to WGS 84 UTM zone 19N, then applied the Haxby.cmap color map, changed the carib-8756 grid display as a wireframe surface and saved all as a combined scene file.

    Edits to the metadata were made to fix any errors that MP v 2.9.32 flagged. This is necessary to enable the metadata to be successfully harvested for various data catalogs. In some cases, this meant adding text "Information unavailable" or "Information unavailable from original metadata" for those required fields that were left blank. Other minor edits were probably performed (title, publisher, publication place, etc.). The metadata date (but not the metadata creator) was edited to reflect the date of these changes. The metadata available from a harvester may supersede metadata bundled within a download file. Compare the metadata dates to determine which metadata file is most recent.

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
  2. How accurate are the geographic locations?
    These data were navigated with Differential Global Positioning Systems (DGPS) and a P-code receiver. These systems have an estimated horizontal accuracy of to +/- 3 meters horizontally.
  3. How accurate are the heights or depths?
    These data have been corrected for vessel motion (roll, pitch, heave, yaw) and referenced to local sea level (no tide correction). The theoretical vertical resolution of the SeaBeam 2112 multibeam echosounder is 1 % of water depth, approximately 40 - 80 meters within the study area.
  4. Where are the gaps in the data? What is missing?
    All collected data were processed and used to produce this dataset.
  5. How consistent are the relationships among the observations, including topology?
    No additional checks for consistency were performed on this data.
