Description:
Abstract:
Bathymetry and seafloor backscatter data for the Flower Gardens National Marine Sanctuary are provided in Raster Grid format.

This data set contains data, metadata, and formal metadata associated with a marine data collection activity referred to by the USGS/CMG Activity ID: A-1-97-GM

Purpose:
These data and information are intended for science researchers, students from elementary through college, policy makers, and general public. Pacific Seaflloor Mapping Project Test cruise.
Supplemental_Information:
Similar information is available for over 1500 other USGS/CMG-related Activities. If known, available are Activity-specific navigation, gravity, magnetics, bathymetry, seismic, and sampling data; track maps; and equipment information; as well as summary overviews, crew lists, and information about analog materials. Primary access to the USGS/CMG Information Bank's digital data, analog data, and metadata is provided through... <http://walrus.wr.usgs.gov/infobank/> This page accomodates a variety of search approaches (e.g., by ship, by region, by scientist, by equipment type, etc.).

A version of this metadata was orginally written by Peter N. Schweitzer (pschweitzer@usgs.gov) USGS - Reston, VA for Dartnell & Gardener (1999) USGS DDS-55 for TIFF images of the bathymetry and seafloor backscatter for the Flower Gardens National Marine Sanctuary. The existing metadata was modified to describe the bathymetry and backscatter rasters included on Scanlon, Ackerman & Rozycki (2003) USGS 03-002.
