Title: GULF - Coastal Vulnerability to Sea-Level Rise: U.S. Gulf Coast
Abstract:
The goal of this project is to quantify, at the National scale, the relative susceptibility of the Nation's coast to sea-level rise through the use of a coastal vulnerability index (CVI). This initial classification is based upon the variables geomorphology, regional coastal slope, tide range, wave height, relative sea-level rise and shoreline erosion and accretion rates. The combination of these variables and the association of these variables to each other furnish a broad overview of regions where physical changes are likely to occur due to sea-level rise.

Why was the data set created?

The purpose of this data layer is to allow the user to view both the coastal vulnerability index (CVI) and the data from which the CVI is calculated (tides, wave height, relative sea-level rise, coastal slope, geomorphology, and shoreline erosion and accretion rate). The CVI provides insight into the relative potential of coastal change due to future sea-level rise. The maps and data presented here can be viewed in at least two ways: 1) as a base for developing a more complete inventory of variables influencing the coastal vulnerability to future sea-level rise to which other elements can be added as they become available; and 2) as an example of the potential for assessing coastal vulnerability to future sea-level rise using objective criteria.

    The Coastal Hazards Database for the U.S. Gulf Coast (Gornitz, V. and White, T. W. 1992. ORNL/CDIAC-60, NDP-043B. Oak Ridge National Laboratory, Oak Ridge, Tennessee), NOS tide and sea-level rise data, WIS wave data, state and U.S. Geological Survey erosion/accretion rate data, NGDC and ETOPO5 elevation data and the Living with the Shore series (Duke University Press, Durham, NC) were used to create this digital dataset. An ArcView .shp file was updated with each attribute. Person who carried out this activity:

    Edits to the metadata were made to fix any errors that MP v 2.9.30 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. In this particular metadata file, most of the edits were related to the entity and attribute information. Most attributes had two entries, one all uppercase and one with lowercase characters. The lowercase attributes were from the original metadata, but did not match the character case of the attribute table, so the information was transferred to the uppercase attributes and the lowercase attributes were deleted. 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.

Oak Ridge National Laboratory, Oak Ridge, Tennessee) updated with data from more recent sources. The data has gone through a series of QA/QC procedures, and is therefore believed to accurately reflect the data gathered in the Coastal Vulnerability to Sea-Level Rise Study.

    none
  3. How accurate are the heights or depths?
    none
