45390 ESIL.AAT Entity Published / External 40833 Sensitivity of Coastal Environments and Wildlife to Spilled Oil: Upper Coast of Texas: ESIL (ESI Shoreline Types - Lines) Data Set Completed The ESIL.AAT table contains attribute information for the vector lines representing linear shoreline features with ESI classification. | Description Source: NOAA ESI Guidelines Converted from FGDC using 'fgdc_to_inport_xml_entity.pl' script. 1 ESI VARCHAR No No Active The item ESI contains values representing the ESI shoreline type. In many cases shorelines are ranked with multiple codes, such as "6B/3A" (listed landward to seaward from left to right). The first code, "6B", is the most landward shoreline type and the second code, "3A", is the shoreline type closest to the water. Singular shoreline types are listed below. No multiple codes are listed, but all multiple codes included in the data set can be assembled from the codes described. The ESI rankings progress from low to high susceptibility to oil spills. To determine the sensitivity of a particular intertidal shoreline habitat, the following factors are integrated: 1) Shoreline type (substrate, grain size, tidal elevation, origin); 2) Exposure to wave and tidal energy; 3) Biological productivity and sensitivity; 4) Ease of cleanup. Prediction of the behavior and persistence of oil in intertidal habitats is based on an understanding of the dynamics of the coastal environments, not just the substrate type and grain size. The intensity of energy expended upon a shoreline by wave action, tidal currents, and river currents directly affects the persistence of stranded oil. The need for shoreline cleanup activities is determined, in part, by the slowness of natural processes in removal of oil stranded on the shoreline. The potential for biological injury, and ease of cleanup of spilled oil are also important factors in the ESI ranking. Generally speaking, areas exposed to high levels of physical energy, such as wave action and tidal currents, and low biological activity rank low on the scale, whereas sheltered areas with associated high biological activity have the highest ranking. | Description Source: NOAA ESI Guidelines 1B: Exposed, Solid Man-made Structures | 2B: Exposed Scarps and Steep Slopes in Clay | 3A: Fine- to Medium-grained Sand Beaches | 3B: Scarps and Steep Slopes in Sand | 5: Mixed Sand and Gravel Beaches | 6A: Gravel Beaches | 6B: Riprap | 7: Exposed Tidal Flats | 8A: Sheltered Rocky Shores and Sheltered Scarps in Bedrock, Mud, or Clay | 8B: Sheltered, Solid Man-made Structures | 8C: Sheltered Riprap | 9A: Sheltered Tidal Flats | 9B: Vegetated Low Banks | 10A: Salt- and Brackish-water Marshes | 10B: Freshwater Marshes | 10C: Swamps | 10D: Scrub-shrub Wetlands | U: Unranked | 2 LINE VARCHAR No No Active Type of geographic feature. | Description Source: NOAA ESI Guidelines S: Shoreline | 3 SOURCE_ID NUMBER No No Active Source identifier that links to the SOURCES data table.

This identifier indicates the source of the ESI classification of a line segment. Vector features that were not surveyed or do not qualify for an ESI classification have a value of -1. | Description Source: NOAA ESI Guidelines 1 - N 6 MOST_SENS VARCHAR No No Active The item MOST_SENS contains values representing the ESI shoreline type. In many cases, shorelines are ranked with multiple codes, such as "6B/3A" (listed landward to seaward from left to right). The item MOST_SENS refers to the most sensitive ESI code in cases of double or triple shoreline values (denoted by a '+' after the value), or a single ESI value in other cases. Generally speaking, areas exposed to high levels of physical energy, such as wave action and tidal currents, and low biological activity rank low on the scale, whereas sheltered areas with associated high biological activity have the highest ranking (and are deemed more sensitive). For the "6B/3A" example above, the "6B" ranking is deemed most sensitive and a '+' is added to let the user know this was a multiple shoreline resulting in a MOST_SENS value of "6B+". | Description Source: NOAA ESI Guidelines 1B: Exposed, Solid Man-made Structures | 2B: Exposed Scarps and Steep Slopes in Clay | 3A: Fine- to Medium-grained Sand Beaches | 3B: Scarps and Steep Slopes in Sand | 5: Mixed Sand and Gravel Beaches | 6A: Gravel Beaches | 6B: Riprap | 7: Exposed Tidal Flats | 8A: Sheltered Rocky Shores and Sheltered Scarps in Bedrock, Mud, or Clay | 8B: Sheltered, Solid Man-made Structures | 8C: Sheltered Riprap | 9A: Sheltered Tidal Flats | 9B: Vegetated Low Banks | 10A: Salt- and Brackish-water Marshes | 10B: Freshwater Marshes | 10C: Swamps | 10D: Scrub-shrub Wetlands | U: Unranked | 7 ESI_DESC Unknown No No Active The item ESI_DESC contains a text description of the item ESI. | Description Source: NOAA ESI Guidelines Acceptable values change from atlas to atlas. gov.noaa.nmfs.inport:45390 Tyler Christensen 2017-04-06T11:44:17 SysAdmin InPortAdmin 2022-08-09T17:11:29 2017-08-10 Office of Response and Restoration ORR 1002 Public No 2017-08-10 1 Year 2018-08-10
