    "descript": "This archive consists of two-dimensional marine seismic reflection profile data collected in Timbalier Bay and in the Gulf of Mexico offshore East Timbalier Island, Louisiana. These data were acquired in June, July, and August of 2001 aboard the R\/V G.K. Gilbert. Included here are data in a variety of formats including binary, American Standard Code for Information Interchange (ASCII), Hyper Text Markup Language (HTML), Portable Document Format (PDF), Rich Text Format (RTF), Graphics Interchange Format (GIF) and Joint Photographic Experts Group (JPEG) images, and shapefiles. Binary data are in Society of Exploration Geophysicists (SEG) SEG-Y format and may be downloaded for further processing or display. Reference maps and GIF images of the profiles may be viewed with a web browser. The Geographic Information Systems (GIS) information provided is compatible with Environmental Systems Research Institute (ESRI) GIS software.  For more information on the seismic surveys see http:\/\/walrus.wr.usgs.gov\/infobank\/g\/g401la\/html\/g-4-01-la.meta.html and http:\/\/walrus.wr.usgs.gov\/infobank\/g\/g501la\/html\/g-5-01-la.meta.html  These data are also available via GeoMapApp (http:\/\/www.geomapapp.org\/) and Virtual Ocean (http:\/\/www.virtualocean.org\/) earth science exploration and visualization applications.",

Distributions are records of substrate characteristics based on visual or photographic inspection or on analysis of samples and cores, and they also include interpretive maps classifying areas on the basis of combinations of observations, hydrodynamic models, or geological models. Assessments include evaluations of present ecological or economic values of substrate distributions, drivers of substrate change, and functions of substrates. Predictions are the results of models or projections of future substrate distributions, values, or ecological impacts, including predicted substrate changes due to natural and human forces including erosion, accretion, sea-level change, extraction, trawling, or other factors; and they are the results of scenario-based models of substrate changes on ecological or economic values under different management strategies or other human alterations."

These data were collected in Timbalier Bay and in the Gulf of Mexico offshore of East Timbalier Island, Louisiana, in June, July, and August of 2001. This map is in geographic projection and was created at a scale of 1:200,000 using ESRI GIS software ArcView 3.2. The image was exported to Adobe Illustrator for further editing and saved for the web in JPEG format. The USGS is not the originator of all layers used in creating the maps presented in this archive. The rivers layer is a Louisiana Oil Spill Coordinator's Office (LOSCO) data set derived from ESRI\/Geographic Data Technology, Inc. (GDT) data that were in turn derived from Bureau of the Census TIGER\/Line files. The water bodies layer is also a LOSCO data set derived from ESRI\/GDT data."
