- Abstract:
-
This data set contains vector lines and polygons representing the shoreline and coastal habitats of the Aleutian Islands classified according to the Environmental Sensitivity Index (ESI) classification system.
This data set comprises a portion of the ESI data for Aleutians East Borough and Aleutians West Coastal Resource Service Area (CRSA). These data identify the marine and coastal environments and wildlife. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources.
- Purpose:
-
The ESI data were collected, mapped, and digitized to provide environmental data for oil spill planning and response. The Clean Water Act with amendments by the Oil Pollution Act of 1990 requires response plans for immediate and effective protection of sensitive resources.

- Attribute_Accuracy_Report:
-
A multi-stage error checking process is used to verify both attribute accuracy and logical consistency throughout data production. The process includes a standardized data entry methodology, hardcopy data review by in-house and external resource experts, a final Quality Assurance/Quality Control (QA/QC) process, and multiple automated logical consistency checks. Quantitative data (such as densities, counts, abundances, or concentrations) provided by resource experts for inclusion in the data set may vary widely in attribute accuracy, depending upon the methodology used to collect and compile such data. For a more detailed evaluation of source data attribute accuracy, contact the sources listed in the Lineage section.
- Logical_Consistency_Report:
-
A multi-stage error checking process, described in the above Attribute_Accuracy_Report, is used to verify both attribute accuracy and logical consistency throughout data production. This process includes multiple automated logical consistency checks that test the files for missing or duplicate data, rules for proper coding, GIS topological consistencies (such as dangles, unnecessary node, etc.), and ORACLE(r) to ARC/INFO(r) consistencies. A final review is made by the GIS manager, where the data are written to CD-ROM and the metadata are written. After the data are delivered to NOAA, they are again subjected to a number of quality and consistency checks.

-
The ESI data set was developed from pre-existing digital sources and reflects the positional accuracy of these original data. The horizontal positional accuracy of the 1:63,360 USGS topographic quads should conform to National Map Accuracy Standards at scales of 1:63,360. The minimum mapping unit (MMU) of the actual shoreline classification segments is estimated at 50 meters when mapping is conducted using 1:63,360 hardcopy fieldmaps. Field verification has shown that the absolute positional accuracy of breaks between shoreline ESI types with a 95-percent error bound is approximately 58 meters. See the Lineage and Process_Description sections for more information on the original source data and how these data were integrated or manipulated to create the final data set.

The intertidal habitats of the Aleutians East Borough were mapped using the ESI shoreline ranking scheme outlined below. In a typical ESI survey, a combination of observational scales is employed. Prior to overflights, existing aerial photos and 1:63,360 topographic maps are examined and parameters such as tidal regime, wave energy, and long-shore sediment transport are assessed through interpretation of coastal landforms by an experienced coastal geologist. If possible, modifications to the digital shoreline to be used in the project are made at this time. Overflights are then conducted, flying at altitudes ranging from 300 to 600 ft. and speeds of 80 knots. The timing of any ESI overflight is dependent upon the timing of the spring low tides. During a five-hour interval of time centered on the peak low tide, a portion of the coast is flown and categorized in the terms of the ESI scale. Mapping only during this interval of time ensures the proper delineation of tidal flats and allows the maximum amount of the intertidal zone to be exposed and evaluated. ESI classifications are denoted directly onto 1:63,360 U.S. Geological Survey (USGS) maps. Additionally, small changes in the shoreline, such as inlet positions or new man-made structures, are drawn onto the basemaps. The final component of an ESI survey is the ground verification of the classifications made during overflights. Depending on logistics, representative examples of each ESI category are surveyed on the ground. The maps used in the field are then digitized by teams of geographers, and the digital shoreline is updated to reflect the observations made during the survey. For the Aleutians East atlas, the ESI shoreline types from the existing hardcopy ESI atlases of Bristol Bay and the southern Alaska Peninsula, which were produced in the 1980s, were digitized and integrated with a newly acquired biological database.
The intertidal habitats of the Aleutians West Coastal Resource Service Area (CRSA) were mapped using two systems: (1) the ESI shoreline ranking scheme, and (2) the Coastal Habitats shoreline ranking scheme.
The shoreline of Unalaska Island was classified using the ESI ranking system during overflights conducted by an experienced coastal geologist on 30 June-3 July 2000. In the course of a typical ESI survey, a combination of observational scales is employed. Prior to overflights, existing aerial photos and 1:63,360 topographic maps are examined and parameters such as tidal regime, wave energy, and long-shore sediment transport are assessed through interpretation of coastal landforms by a coastal geologist. If possible, modifications to the digital shoreline to be used in the project are made at this time. Overflights are then conducted, flying at altitudes ranging from 300 to 600 ft. and speeds of 80 knots. The timing of any ESI overflight is solely dependent upon the timing of the spring low tides. During a five-hour interval of time centered on the peak low tide, a portion of the coast is flown and categorized in the terms of the ESI scale. Mapping only during this interval of time ensures the proper delineation of tidal flats and allows the maximum amount of the intertidal zone to be exposed and evaluated. ESI classifications are denoted directly onto 1:63,360 U.S. Geological Survey (USGS) maps. Additionally, small changes in the shoreline, such as inlet positions or new man-made structures, are drawn onto the basemaps. The final component of an ESI survey is the ground verification of the classifications made during overflights. Depending on logistics, representative examples of each ESI category are surveyed on the ground. In the case of Unalaska, ground-truthing locations included: the north shore of Beaver Inlet near Ugadaga bay; Summer Bay; Iliuliuk Bay; Dutch Harbor; the northern and eastern shores of Amaknak Island, and Captains Bay. The maps used in the field are then digitized by teams of geographers and the digital shoreline is updated to reflect the observations made during the survey.
The shorelines of all other islands in the Aleutians West CRSA, from Attu to Umnak, were mapped at a scale of 1:250,000 by the same coastal geologist using the more general Coastal Habitat classification system. Overflights of these islands were not conducted, hence the separate mapping scheme. While interest remains high in conducting traditional field-oriented ESI surveys for these islands, budget considerations and logistical factors such as fuel staging, a short field season, habitation, and helicopter availability must be addressed. The mapping done in the Coastal Habitat classification scheme is based on field experience gained in the Unalaska mapping effort, National Imaging and Mapping Agency (NIMA) 1:250,000 topographic maps, USGS bulletin series 1028 (1951-1971) and local expertise. These classifications are not field checked. The categories in the Coastal Habitat scheme are similar to those included in the previous Aleutians West CRSA Resource Inventory atlas. However, the Coastal Habitat scheme improves on the previous work in that individual beaches are mapped as distinct coastal habitats.

- Attribute_Label: ESI
- Attribute_Definition:
-
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 code definition changes based on the associated ENVIR item code. For example, the definition of a line with an ESI of "4" and an ENVIR code of "E" (for Estuarine) is "Coarse-grained sand beaches", while the definition of a line with an ESI of "4" and an ENVIR code of "C" (for Coastal Habitat) is "Exposed tidal flats". The Coastal Habitat mapping scheme is based on the same factors and principles as the ESI mapping system; however, because it is not a field survey based mapping scheme, it provides less resolution. It should be noted that the Coastal Habitat mapping scheme is for estuarine environments. For each ESI code definition below, the associated ENVIR code is referenced in parentheses.
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.

Contact NOAA for distribution options (see Distributor). ESI data are processed into multiple formats to make them useful to a wider community of GIS/mapping users. Distribution formats include ARC export, MOSS and Shape files, and MARPLOT map folders. An ArcView ESI project and ESI_Viewer product are also included on the distribution CDs for ease of use of the ESI data. The database files are distributed both in the NOAA standard relational database format (see NOAA Technical Memorandum NOS ORCA 115) and in a simplified desktop flat file format. This metadata document includes information on both of these database formats.
