Data Releases

This data release includes turbidity, discharge, suspended-sediment concentration (SSC) and particle-size data that were collected by the U.S. Geological Survey (USGS) between February 2013 and January 2017 at the Duwamish River, Washington, within the tidal influence at river kilometer 16.7 (USGS site 12113390; Duwamish River at Golf Course at Tukwila, WA). Additionally included in this release a

Although ecosystem service (ES) modeling has progressed rapidly in the last 10-15 years, comparative studies on data and model selection effects have become more common only recently. Such studies have drawn mixed conclusions about whether different data and model choices yield divergent results. In this study we apply inter- and intra-model comparisons to address these questions at national and p

This data release encompass numerous studies examining soil properties and greenhouse gas fluxes of Prairie Pothole Region (PPR) wetland catchments. The PPR is one of the largest wetland ecosystems in the world, encompassing approximately 770,000 square kilometers of the north-central U.S. and south-central Canada, with the U.S. portion including parts of Iowa, Minnesota, South Dakota, North Dakot

We performed ring shear strength testing of three specimens from a glaciolacustrine silty clay unit involved in a large landslide that occurred March 22, 2014 near the town of Oso, Washington. Ring shear tests utilized apparatus DPRI-5 at Kyoto University, Japan and test results are presented herein. We refer to the specimens as the clay, clayey silt, and silt. Some tests were performed under cont

We performed hourly monitoring of conditions at the Two Towers landslide located in northern California near the town of Zenia. Monitored conditions included rainfall, groundwater head, horizontal total stress, horizontal effective stress, vertical soil deformation, and subsurface displacement. Data were acquired November 11, 2014-July 22, 2017, except for times during which power failure occurred

The U.S. Geological Survey (USGS) has developed and implemented an automated algorithm that identifies burned areas in temporally-dense time series of Landsat image stacks to produce the Landsat Burned Area Essential Climate Variable (BAECV) products. The algorithm makes use of predictors derived from individual Landsat scenes, lagged reference conditions, and change metrics between the scene and

These data were compiled in order to represent long-term (multi-decadal) forest growth across eight different experimental forests in the United States, each with replicated levels of density treatments, as well as an important drought index correlated to growth. Forests around the world are experiencing severe droughts and elevated competitive intensity due to increased tree density. These data c

Defining full life cycle biology is critical for comprehensive conservation planning. To that end, life history information on the endangered Mariana swiftlet (Aerodramus bartschi) is scarce. Therefore, this study examined the reproductive biology of the Mariana swiftlet over five annual cycles on the island of Oahu in the Hawaiian Islands. This introduced population used a human-made tunnel for r

The data were generated as part of a study to determine if buccal (oral) swabs could be used to obtain genetic material from Red-Cockaded Woodpecker chicks. Different swab types were investigated to determine if any specific type gave the highest DNA yields.

The shapefile associated with this metadata file represents the spatial distribution of mean annual water-budget components, in inches, for the Island of Kauai, Hawaii. The water-budget components in the shapefile were computed by a water-budget model for a scenario representative of current conditions (2001-10 rainfall and 2001-10 land cover), as described in U.S. Geological Survey Scientific Inv

The shapefile associated with this metadata file represents the spatial distribution of mean annual water-budget components, in inches, for the Island of Kauai, Hawaii. The water-budget components in the shapefile were computed by a water-budget model for a scenario representative of recent conditions (1978-2007 rainfall and 2010 land cover), as described in USGS Scientific Investigations Report (

The shapefile associated with this metadata file represents the spatial distribution of mean annual water-budget components, in inches, for the Island of Kauai, Hawaii. The water-budget components in the shapefile were computed by a water-budget model for a scenario representative of predevelopment conditions (1978-2007 rainfall and 1870 land cover), as described in USGS Scientific Investigations
