The majority of GCR sites, therefore, now have statutory protection through designation as notified features in SSSIs. In these cases the GCR site boundary indicates the extent of the Earth science interest within the SSSI. Some GCR sites, however, remain unnotified and are known as unnotified GCR sites. National Park Authorities and some Local Authorities treat these as candidate SSSIs and afford them the same protection as SSSIs. Some unnotified GCR sites are also Local Geodiversity Sites (LGS), and as such they are afforded levels of protection appropriate to locally important sites (though they are, themselves, considered to be of national or international importance).The remaining unnotified GCR sites have no statutory protection, although they are considered to be sites of national or international importance. Initially developed between 1977 and 1990, the GCR network is periodically updated and this dataset is subject to change. Boundaries of GCR sites are often not co-incident with SSSIs.More information: https://www.nature.scot/professional-advice/protected-areas-and-species/protected-areas/local-designations/geological-conservation-review-sites

This is a spatial dataset that describes the geographic extent and location of areas that are listed under Limestone Pavement Orders. Limestone pavements are outcrops of limestone where the surface has been worn away by natural means over millennia. These rocks have the appearance of paving blocks, hence their name. Not only do they have geological interest, they also provide valuable habitats for wildlife. These habitats are threatened due to their removal for use in gardens and water features. Many limestone pavements have been designated as SSSIs which affords them some protection. In addition, Section 34 of the Wildlife and Countryside Act 1981 gave them additional protection via the creation of Limestone Pavement Orders, which made it a criminal offence to remove any part of the outcrop. The associated Limestone Pavement Priority Habitat is part of the UK Biodiversity Action Plan priority habitat in England. This is published separately. Full metadata can be viewed on data.gov.uk.

New Mexico has a rich legacy of petroleum and mineral exploration and production, most of which has involved subsurface investigations. Hundreds of thousands of holes have been drilled into the subsurface, some to depths of 20,000 feet or more. Considerable data have been collected from these wells in the form of electrical or geophysical logs, cuttings, and rock cores. These materials contain a rich lode of information about the kinds of rocks that lie below the surface, how porous and permeable they are, and even what types of fluids they contain. Part of the Mission of New Mexico Bureau of Geology and Mineral Resources is to serve as a repository for these kinds of data. Data in our collections have been acquired from wells drilled throughout the state over the last 90 years. We currently have more than 15 million pieces of unique subsurface data in our collections, much of it stored in seven steel storage buildings on campus. Core - 20,000+ boxes (oil & gas and mining) from 4,000+ wells Cuttings - 51,0000+ boxes from 16,600+ wells Geophysical Logs (some with mudlogs)- 50,000+ wells Porosity and Permeability Analyses Petroleum Source Rock Analyses Well records - 100,000+ wells Drillers logs - 17,000+ wells Sample descriptions and sample logs - 4,300+ wells Historic petroleum exploration maps with well locations in 26 counties Pool maps with locations of producing oil and gas pools by stratigraphic unit Historic production data - Pre-2002

The Channel Migration Potential (CHAMP) layer contains stream networks of Western Washington (and much of Western Oregon) with associated data and information important for assessing channel migration activity. It also features information on channel characteristics such as stream flow and physical dimensions. This data layer’s main feature is a classification of channel migration potential based on channel confinement and erosion potential. The layer was derived from existing statewide geospatial datasets and classified according to channel migration measurements by the High Resolution Change Detection (HRCD) project for the Puget Sound Region (Washington Department of Fish and Wildlife, 2014). While the layer identifies the potential for channel migration, it does not predict channel migration rates. Thus, this data layer should be used to screen and prioritize stream reaches for further channel migration evaluation. The tool helps plan and prioritize floodplain management actions such as Channel Migration Zone mapping, erosion risk reduction, and floodplain restoration. The background, use, and development of the CHAMP layer are fully described in Ecology Publication 15-06-003 (full report citation and URL below). That report also describes visual assessment techniques that should be used along with the CHAMP layer to assess channel migration potential. Legg, N.T. and Olson, P.L., 2015, Screening Tools for Identifying Migrating Stream Channels in Western Washington: Geospatial Data Layers and Visual Assessments: Washington State Department of Ecology Publication 15-06-003, 40 p. https://fortress.wa.gov/ecy/publications/SummaryPages/1506003.htmlThe tool developers would like to thank the following people for their contribution to this work: • Brian D. Collins (University of Washington) • Jerry Franklin (Washington Department of Ecology) • Christina Kellum (Washington Department of Ecology) • Matt Muller (Washington Department of Fish and Wildlife) • Hugh Shipman (Washington Department of Ecology) • Terry Swanson (Washington Department of Ecology) This project has been funded wholly or in part by the United States Environmental Protection Agency under Puget Sound Ecosystem Restoration and Protection Cooperative Agreement Grant PC-00J27601 with Washington Department of Ecology. The contents of this document do not necessarily reflect the views and policies of the Environmental Protection Agency, nor does mention of trade names or commercial products constitute endorsement or recommendation for use.Generally, this data layer should be used to screen and prioritize stream reaches for further channel migration evaluation. The data resolution does not allow one to predict channel migration. The classification identifies stream segments for further examination, and those that likely require limited attention or analysis. The potential uncertainty involved in the classification approach is a reason for the visual assessment techniques (described below in Ecology Publication 15-06-003) being described along with the CHAMP data layer.

From the site: "Cell maps for each oil and gas assessment unit were created by the USGS as a method for illustrating the degree of exploration, type of production, and distribution of production in an assessment unit or province. Each cell represents a quarter-mile square of the land surface, and the cells are coded to represent whether the wells included within the cell are predominantly oil-producing, gas-producing, both oil and gas-producing, dry, or the type of production of the wells located within the cell is unknown. The well information was initially retrieved from the IHS Energy Group, PI/Dwights PLUS Well Data on CD-ROM, which is a proprietary, commercial database containing information for most oil and gas wells in the U.S. Cells were developed as a graphic solution to overcome the problem of displaying proprietary PI/Dwights PLUS Well Data. No proprietary data are displayed or included in the cell maps. The data from PI/Dwights PLUS Well Data were current as of October 2001 when the cell maps were created in 2002."

From the site: "The Assessment Unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The Assessment Unit is defined within the context of the higher-level Total Petroleum System. The Assessment Unit is shown here as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the province and incorporates a set of known or postulated oil and (or) gas accumulations sharing similar geologic, geographic, and temporal properties within the Total Petroleum System, such as source rock, timing, migration pathways, trapping mechanism, and hydrocarbon type. The Assessment Unit boundary is defined geologically as the limits of the geologic elements that define the Assessment Unit, such as limits of reservoir rock, geologic structures, source rock, and seal lithologies. The only exceptions to this are Assessment Units that border the Federal-State water boundary. In these cases, the Federal-State water boundary forms part of the Assessment Unit boundary."

These maps delineate the entire Puget Sound shoreline by geomorphic type. The primary purpose of the mapping was to identify feeder bluffs, eroding shorelines that are important to maintaining nearby beaches. Knowledge of the distribution of these features can be used by local planners and resource agencies to better manage Puget Sound shorelines. The study emphasized mapping of coastal bluffs, but also extended to a wide range of other coastal landforms, including rocky shores, river deltas, and small lagoons and estuaries. This mapping project is described in the following report, available from the Department of Ecology: MacLennan., A. Johannessen, J.W., Williams, S.A., Gerstel, W., Waggoner, J.F., and Bailey, A., 2013, Feeder Bluff Mapping of Puget Sound, prepared by Coastal Geologic Services, Bellingham, for Washington Department of Ecology, Olympia WA, 117 pp and map folio.

This dataset is a statewide polygon coverage of sand, gravel, and stone resources. This database includes the best data available from the VT Agency of Natural Resources and VTrans quadrangle maps where sand and gravel locations are noted. Sources are maps from "Geology for Environmental Planning" booklets prepared by Charles G. Doll in the 1970's, the data were derived from USGS sources. VCGI expects that this data will be updated and added to by other sources, but it is the most complete/accurate data available to us at this time.

Littoral drift, or shore drift, is the process by which beach sediment is moved along the shoreline. Drift results primarily from the oblique approach of wind-generated waves and can therefore change in response to short-term (daily, weekly, or seasonally) shifts in wind direction. Over the long term, however, many shorelines exhibit a single direction of net shore drift. Net shore-drift is determined through geomorphologic analysis of beach sediment patterns and of coastal landforms. Many shorelines can be divided into discrete littoral, or drift, cells, which are independent of one another and for which distinct sediment sources and sinks can be identified. This coverage denotes the extent of individual littoral cells and the direction of net shore-drift within each.

The digital maps presented here were originally published as hard copy maps in the Coastal Zone Atlas of Washington between 1978 and 1980. Although the Atlas has been out of print for many years, the maps contain information that remain the basis for local planning decisions. After receiving multiple requests for electronic versions of portions of the Atlas, an effort was made to scan, georeference and digitize aspects of the Atlas, beginning with the slope stability maps. These maps indicate the relative stability of coastal slopes as interpreted by geologists based on aerial photographs, geological mapping, topography, and field observations. Such methods are standard, but may occasionally result in some unstable areas being overlooked and in some stable areas being incorrectly identified as unstable. Further inaccuracies are introduced to the data through the process of converting the published maps into digital format. Important land use or building decisions should always be based on detailed geotechnical investigations. This mapping represents conditions observed in the early and mid-1970s. Shorelines and steep slopes are dynamic areas and many landslides have occurred since that time that are not reflected on these maps. Subsequent human activities may have increased or decreased the stability of some areas.

(Link to Metadata) This coverage represents the results of an analysis of landscape diversity in Vermont. Polygons in the dataset represent as much as possible (in a limited area) of the physical diversity in each of the state's 8 biophysical regions (BPRs)-- hence the name "representative landscapes" (RLs). Units of physical diversity were based on elevation, bedrock type, surficial deposits, and landform. Numbers of unique landscape diversity unit labels occurring in the 8 BPRs ranged from 586 to 956. Percent of diversity units represented in the RL polygons in this dataset ranged from a low of 74% (in 25% of the Champlain Valley BPR) to 87% (in 23% of the Northern Piedmont BPR). The most efficient repesentations were in the Northeastern Highlands and the Champlain Valley, where 83% and 81% (respectively) of the landscape diversity units occurring in the BPRs were represented in 17% of the BPR area.
