This dataset contains geochemical data for unconsolidated sediments (stream sediments, lake sediments, etc.) collected by U.S. Geological Survey (USGS) personnel and analyzed in the analytical laboratories of the Geologic Division of the USGS. These data represent analyses of sediment samples collected in support of various USGS programs. The data were originally entered into the in-house Rock Analysis Storage System (RASS) database which was used by the Geologic Division from the early-1970's through the late-1980's to archive geochemical data. An unpublished CD-ROM was developed in 1996 that contains the RASS data in GSSEARCH format. That CD was used to generate this data set.

These datasets consist of a workspace (folder) containing a collection of gridded datasets plus a personal geodatabase containing several vector datasets. These datasets are designed to be used with the ArcHydro Tools, developed by ESRI in partnership with the U.S. Geological Survey, StreamStats Development Team. The datasets, together with the ArcHydro Tools, allow users to delineate watersheds and compute several watershed characteristics. The datasets are distributed in folders named for the 8-digit Hydrologic Unit Code (HUC) each covers. The data structure is the same for each HUC.

This metadata is for the vegetation and land-use geo-spatial database for Minidoka National Historic Site (MIIN), Idaho and surrounding areas. This project is authorized as part of the USGS/NPS Vegetation Classification and Mapping Program. The program is being administered by the National Park Service's (NPS) Inventory and Monitoring Program in conjunction with the Biological Resources Division (BRD) of the United States Geological Survey (USGS). This mapping effort was performed by Cogan Technology Inc. (CTI) as a free service to the National Park Service.

This metadata is for the vegetation and land-use geo-spatial database for Pu'ukohola Heiau National Historic Site (PUHE) , Island of Hawai'i and surrounding areas. This project is authorized as part of the USGS/NPS Vegetation Inventory Program. The program is being administered by the National Park Service's (NPS) Inventory and Monitoring Program in conjunction with the Biological Resources Division (BRD) of the United States Geological Survey (USGS). This mapping effort was performed by Cogan Technology Inc. (CTI) under contract to the Pacific Island Inventory and Monitoring Network (UCBN) of the National Park Service.

The geographic information system (GIS) format spatial data set of vegetation for Apostle Islands National Lakeshore (APIS) was created for the National Park Service (NPS) Vegetation Inventory Program (VIP). The APIS covers an area of approximately 28,972 ha (71,591 acres). The map classification scheme used to create the vegetation data set is designed to represent local vegetation types at the finest level possible using the National Vegetation Classification (NVC) Standard (Vr 2). Physiognomic information was also recorded, including height (woody vegetation), canopy density, and coverage patterns. The vegetation data set was developed by interpreting aerial photographs collected in 2004 and extensive field surveys....

Winter climate change has the potential to have a large impact on coastal wetlands in the southeastern U.S. Warmer winter temperatures and reductions in the intensity of freeze events would likely lead to mangrove forest range expansion and salt marsh displacement in parts of the U.S. Gulf of Mexico and Atlantic coast. The objective of this research was to better understand some of the ecological implications of mangrove forest migration and salt marsh displacement. The potential ecological effects of mangrove migration are diverse ranging from important biotic impacts (e.g., coastal fisheries, land bird migration; colonial nesting wading birds) to ecosystem stability (e.g., response to sea level rise and drought;...

This polygon data set includes the protected areas of the Northern Mountain States of the United States of America that are managed by national, state, provincial, or territorial authorities. As defined by the International Union for the Conservation of Nature (IUCN), a protected area is an area of land and/or sea especially dedicated to the protection and maintenance of biological diversity, and of natural and associated cultural resources, and managed through legal or other effective means. The data set was assembled for the Commission for Environmental Cooperation (CEC) from other public data sets containing data on protected areas in Canada, Mexico, and the United States. Protected area data was obtained from...

This dataset consists of a personal geodatabase containing several vector datasets. These datasets may be used with the ArcHydro Tools, developed by ESRI in partnership with the U.S. Geological Survey, StreamStats Development Team. The datasets, together with the ArcHydro Tools and the ArcHydro 8-digit HUC datasets for an area of interest, allow users to delineate watersheds and compute several watershed characteristics.

This data consists of data grids for the entire United States area, including 1 X 2 Degree, 1 X 1 Degree, 30 X 60 Minute, 15 X 15 Minute, 7.5 X 7.5 Minute, and 3.75 X 3.75 Minute. The grid was generated using ESRI ArcInfo GIS software.
