Book Description
This document describes the contents of a digital data base that may be used to identify coastlines along the US Gulf Coast at risk to sea-level rise. The data base integrates point, line, and polygon data for the US Gulf Coast into 0.25[degree] latitude by 0.25[degree] longitude grid cells and into 1:2,000,000 digitized line segments that can be used by raster or vector geographic information systems (GIS) as well as by non-GIS data base systems. Each coastal grid cell and line segment contains data on elevation, geology, geomorphology, sea-level trends, shoreline displacement (erosion/accretion), tidal ranges, and wave heights. To allow for the identification of coastlines at risk from sea-level rise, 7 of the 22 original data variables in this data base were classified by vulnerability and used to create 7 relative risk variables. These relative risk variables range in value from 1 to 5 and may be used to calculate a coastal vulnerability index for each grid cell and/or line segment. The data for these 29 variables (i.e., the 22 original variables and 7 risk variables) have been placed into the following data formats: (1) Gridded polygon data for the 22 original data variables. Data include elevation, geology, geomorphology, sea-level trends, shoreline displacement (erosion/accretion), tidal ranges, and wave heights. (2) Gridded polygon data for the seven classified risk variables. The risk variables are classified versions of: mean coastal elevation, geology, geomorphology, local subsidence trend, mean shoreline displacement, maximum tidal range, and maximum significant wave height. (3) 1:2,000,000 line segment data containing the 29 data variables (the 22 original data variables and the seven classified risk variables). (4) Supplemental point data for the stations used in calculating the sea-level trend and tidal range data sets. (5) Supplemental line segment data containing a 1:2,000,000 digitized coastline of the US Gulf Coast as defined by this document.

Book Description
Beach erosion is a chronic problem along open-ocean shores of the U.S. As coastal populations continue to grow and community infrastructures are threatened by erosion, there is increased demand for accurate info. regarding past and present trends and rates of shoreline movement, and a need for a comprehensive analysis of shoreline movement. This report on states bordering the Gulf of Mexico (Florida, Alabama, Mississippi, Louisiana, and Texas) summarizes the methods of analysis, interprets the results, provides explanations regarding the historical and present trends and rates of change, and describes how different coastal communities are responding to coastal erosion in 2004 (prior to Hurricanes Katrina and Rita). Illustrations.

Book Description
The many economic factors affecting sustainability of the Gulf of Mexico region are perhaps as important as the waves on its shores and its abundant marine life. This second volume in Gulf of Mexico Origin, Waters, and Biota (a multivolumed work edited by John W. Tunnell Jr., Darryl L. Felder, and Sylvia A. Earle) assesses the Gulf of Mexico as a single economic region. The book provides information and baseline data useful for assessing the goals of economic and environmental sustainability in the Gulf. In five chapters, economists, political scientists, and ecologists from Florida, California, Louisiana, Texas, Maine, and Mexico cover topics such as: the idea of the Gulf as a transnational community; the quantitative value of its productivity; a summary of the industries dependent on the Gulf, including shipping, tourism, oil and gas mining, fisheries, recreation, and real estate; the human uses and activities that affect coastal economies; and the economic trends evident in Mexico's drive toward coastal development. This first-of-its-kind reference work will be useful to scientists, economists, industry leaders, and policy makers whose work requires an understanding of the economic issues involved in science, business, trade, exploration, development, and commerce in the Gulf of Mexico.
