    "descript": "This report consists of two-dimensional marine seismic reflection profile data from Crescent Beach Spring, Florida. These data were acquired in April of 1999 with the Research Vessel G.K. Gilbert. The data are available in a variety of formats, including binary, ASCII, HTML, and GIF images. Binary data are in Society of Exploration Geophysicists (SEG) SEG-Y format and may be downloaded for further processing or display. Trackline maps and GIF images of the profiles may be viewed with your WWW browser.  For more information on the seismic surveys see http:\/\/walrus.wr.usgs.gov\/infobank\/g\/g199fl\/html\/g-1-99-fl.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."
