This dataset provides timeseries data on water quality and quantity, as collected or computed from outside sources. The format is many tables with one row per time series observation (1 tab-delimited file per site-variable combination, 1 zip file per site). This compilation of data is intended for use in estimating or interpreting metabolism. Sites were included if they met the initial criteria of having at least 100 dissolved oxygen observations and one of the accepted NWIS site types ('ST','ST-CA','ST-DCH','ST-TS', or 'SP'). This dataset is part of a larger data release of metabolism model inputs and outputs for 356 streams and rivers across the United States (https://doi.org/10.5066/F70864KX). The complete release...
This dataset contains small cutthroat trout lakes within Southeast Alaska. These are smaller lakes that do not produce cutthroat trout large enough to reach the 11-inch regional minimum size limit. Each of these lakes has a 9-inch minimum size limit, and bait is prohibited. Regionwide limits of 2 per day and 2 in possession apply. Currently there are seven lakes in Southeast Alaska with the small cutthroat lake designation. Please verify fishing regulations with current Alaska Department of Fish and Game Sport Fishing Regulations at the following link: http://www.adfg.alaska.gov/index.cfm?adfg=fishregulations.se_sportfish
This map layer is a grid map of 1998 peak vegetation growth for Alaska and the conterminous United States. The nominal spatial resolution is 1 kilometer and the map layer is based on 1-kilometer AVHRR data. The data were compiled by staff at the USGS Center for Earth Resources Observation and Science.
This dataset, termed "GAGES II", an acronym for Geospatial Attributes of Gages for Evaluating Streamflow, version II, provides geospatial data and classifications for 9,322 stream gages maintained by the U.S. Geological Survey (USGS). It is an update to the original GAGES, which was published as a Data Paper on the journal Ecology's website (Falcone and others, 2010b) in 2010. The GAGES II dataset consists of gages which have had either 20+ complete years (not necessarily continuous) of discharge record since 1950, or are currently active, as of water year 2009, and whose watersheds lie within the United States, including Alaska, Hawaii, and Puerto Rico. Reference gages were identified based on indicators that they...

Map quadrangle boundaries for the 1:63,360-scale maps of Alaska, with unique identification codes conforming to the scheme used in the related data set quad24, which contains 1:24,000-scale quadrangle names and codes for the conterminous US and Hawaii.
Layers of geospatial data include contours, boundaries, land cover, hydrography, roads, transportation, geographic names, structures, and other selected map features.

This map layer portrays 1993 to 2001 estimates for total personal income, per capita personal income, annual number of full-time and part- time jobs, average wage per job in dollars, population, and per capita number of jobs, for counties in the United States. Total personal income is all the income that is received by, or on behalf of, the residents of a particular area. It is calculated as the sum of wage and salary disbursements, other labor income, proprietors' income with inventory valuation and capital consumption adjustments, rental income of persons with capital consumption adjustment, personal dividend income, personal interest income, and transfer payments to persons, minus personal contributions for social...
This map layer portrays a selected set of information that was collected for the 2007 Census of Agriculture by the National Agricultural Statistics Service, U.S. Department of Agriculture. There are 25 categories of data which include information about farms, crops, livestock, values of products, and farm operator characteristics. The data is for the United States and is presented by county. This is a replacement for the June 2005 Agriculture Census of the United States – 2002 map layer.
This map layer portrays the Congressional Districts of the United States for the 108th Congress. Lines coincident with Congressional District boundaries were extracted from the existing National Atlas County Boundaries layer. In areas lacking coincident geometry, lines from State data sets or from an Election Data Services data set were integrated into the file. This is an update of the March 2003 map layer.
The Topographic and Bathymetric Shaded Relief of North America map layer shows depth and elevation ranges using colors, with relief enhanced by shading. The image was derived from two pre-existing map layers; the Bathymetric Shaded Relief of North America, derived from ETOPO2 data, and the Color North America Shaded Relief, derived from GTOPO30 data.
This map layer is a grid map of 2001 average vegetation growth for Alaska and the conterminous United States. The nominal spatial resolution is 1 kilometer and the map layer is based on 1-kilometer AVHRR data. The data were compiled by staff at the USGS Center for Earth Resources Observation and Science.
This data set portrays election results, by counties for 49 States and by election districts for Alaska, for the 2004 Presidential general election. Reported for each county are the popular vote count for the Democratic Party candidate, the Republican Party candidate, and all other votes. Also reported are the percentage of the vote cast for each party’s candidate, based on the total number of valid votes cast. Over votes (ballots which contained votes for more than one candidate) and under votes (ballots which contained votes for no candidate) are not included in the total number of votes reported. For details particular to each State, see the Process Steps.
This map layer consists of federally owned or administered lands of the United States, Puerto Rico, and the U.S. Virgin Islands. Only areas of 640 acres or more are included. There may be private inholdings within the boundaries of Federal lands in this map layer. This is a revised version of the December 2005 map layer.
This map layer shows Omernik's Level III ecoregions, derived from a 1:7,500,000 map created by J.M. Omernik in 1987 and from refinements of Omernik's framework that were made for other projects. Ecoregions describe areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. Omernik's ecoregions are based on the premise that a hierarchy of ecological regions can be identified through the analysis of the patterns and the composition of both living and nonliving phenomena, such as geology, physiography, vegetation, climate, soils, land use, wildlife, and hydrology, that affect or reflect differences in ecosystem quality and integrity. All the characteristics are considered...
This map layer shows isoclinic lines (lines of constant inclination of the Earth's magnetic field), derived from the International Geomagnetic Reference Field (IGRF) for the epoch 1995.0. Magnetic inclination is the angle between the magnetic field vector and the horizontal plane.
This map layer is a grid map of 1996 average vegetation growth for Alaska and the conterminous United States. The nominal spatial resolution is 1 kilometer and the map layer is based on 1-kilometer AVHRR data. The data were compiled by staff at the USGS Center for Earth Resources Observation and Science.
This data set includes U.S. Census Bureau 1990 population information for the United States, presented by county. Included are total population counts; various statistics on race, ethnic, and gender distributions; income statistics; urban and rural statistics, and median age. This is a revised version of the July, 2004, data set, with data for urban and rural statistics added.
