The Integrated Scenarios of the Future Northwest Environment project (an FY2012 NW CSC funded project), resulted in several datasets describing projected changes in climate, hydrology and vegetation for the 21st century over the Northwestern US. The raw data is available in netCDF format, which is a standard data file format for weather forecasting/climate change/GIS applications. However, the sheer size of these datasets and the specific file format (netCDF) for data access pose significant barriers to data access for many users. This is a particular challenge for many natural/cultural resource managers and others working on conservation efforts in the Pacific Northwest. The goal of this project was to increase...

This report summarizes the results of velocity measurements ofoutlet glaciers, ice streams, and ice shelves around theAntarctic periphery. For some regions, where suitable imageswere available, the same area was measured repeatedly tovalidate the data or register changes in velocity with time.The results given here are a compendium of published papersand work in progress. The results constitute a data base thatwill be added to and amended as more velocity measurementsbecome available.

Bull trout (Salvelinus confluentus), listed as threatened under the Endangered Species Act, are among the more thermally sensitive of coldwater species in North America. The Boise River upstream of Arrowrock Dam in southwestern Idaho (including Arrowrock Reservoir) provides habitat for one of the southernmost populations of bull trout. The presence of the species in Arrowrock Reservoir poses implications for dam and reservoir operations. From 2011 to 2014, the Bureau of Reclamation and the U.S. Geological Survey collected fish telemetry data to improve understanding of bull trout distribution and movement in Arrowrock Reservoir and in the upper Boise River tributaries. The U.S. Geological Survey compiled the telemetry...

This data set contains daily survival rates from 81 studies of passerine obligate grassland bird species that primarily breed in the United States; patch size information was extracted when available. Temperature and precipitation variables were calculated for the study sites and years the data were collected. The studies we used collected data across the period 1978 to 2013.

This report contains all of the available daily sulfur dioxide andcarbon dioxide emission rates from Cook Inlet volcanoes asdetermined by the U.S. Geological Survey (USGS) from March 1990through July 1994. Airborne sulfur dioxide gas sampling of theCook Inlet volcanoes (Redoubt, Spurr, Iliamna, and Augustine)began in 1986 when several measurements were carried out atAugustine volcano during the eruption of 1986. Systematic monitoringfor sulfur dioxide and carbon dioxide began in March 1990 atRedoubt volcano and continues to the present. Intermittentmeasurements at Augustine and Iliamna volcanoes began in 1990 andcontinues to the present. Intermittent measurements began at Spurrvolcano in 1991, and were continued...

A comma separated values (csv) file that is a snapshot of the U.S. Geological Survey peak flow file on November 19, 2008. The file lists agency, station identification, water year, peak date, peak values, peak qualification codes, gage height values, gage height qualification codes and year of last peak for all stream gaging stations for which peak streamflow has been recorded.

A rich legacy of geochemical data produced since the early 1960s covers the great expanse of Alaska; careful treatment of such data may provide significant and revealing geochemical maps that may be used for landscape geochemistry, mineral resource exploration, and geoenvironmental investigations over large areas. To maximize the spatial density and extent of data coverage for statewide mapping of element distributions, we compiled and integrated analyses of more than 175,000 sediment and soil samples from three major, separate sources: the U.S. Geological Survey, the National Uranium Resource Evaluation program, and the Alaska Division of Geological & Geophysical Surveys geochemical databases. Various types of...

A comma separated values (csv) file that is a snapshot of percent difference between November 19, 2008 and November 14, 2016 peak streamflow. The file lists station identification, water year, original (2008) peak Q, current (2016) peak Q and percent difference calculated per water year. The percent difference was calculated as the absolute value of [(current peak Q - original peak Q)/(original peak Q) x 100], where current peak Q is the 2016 peak and the original peak Q is the 2008 peak. When an original peak Q value is 0, the resultant percent difference calculation is undefined because of division by 0. In these cases, the percent difference field is populated with NA. Those entries are included in the data file...

The U.S. Geological Survey recovered 9 piston cores from theNorthwind Ridge in the Canada Basin of the Arctic Ocean from acruise of the USCGC Polar Star during 1988. Preliminaryanalysis of the cores suggests sediments deposited onNorthwind Ridge preserve a detailed record of glacial andinterglacial cycles for the last few hundred-thousand to onemillion years. This report includes quantitative data onforaminifers and selected sediment size-fraction data in 98samples from Northwind Ridge core PI-88AR P3, 51 samples fromcore PI-88-AR P7 and 117 samples from core PI-88-AR P9.

Temperature data were collected from ~40 portable data (temperature) loggers and two weather stations located in central North Carolina, USA during August 2015. In addition to temperature, solar radiation and wind speed data were recorded at one of the sites to estimate the effects of these climate variables on sensor bias.

Dust samples taken annually for five years from 55 sites insouthern Nevada and California provide an unparalleled sourceof information on modern rates of dust deposition, grain size,and mineralogical and chemical composition. The relations ofmodern dust to climatic factors, type and lithology of dustsource, and regional wind patterns shed new light on theprocesses of dust entrainment and deposition.A project to study modern dust deposition relative to soils insouthern Nevada and California was initiated in 1984 under theauspices of the Yucca Mountain Site Characterization Project(Interagency Agreement DE-AI08-78ET44802). The primary purposeof the dust-deposition project was to provide data on moderndust composition...
