Data

Data consist of geolocation, temperature, turbidity, time, and dye concentrations collected at four downstream locations from Rhodamine WT dye injection point on Yellowstone River in June 2017

Image and biometric data were collected for 22 species of fish from Great Lakes Tributaries in Michigan and Ohio, and the Illinois River for the purpose of developing a fish identification classifier. Data consists of a comma delimited spreadsheet that identifies image file names and associated fish identification number, common name, species code, family name, genus, and species, date collected,

This dataset contains nesting information for birds breeding at a site on the Colville River, Alaska, 2011-2018. Nests were located during area searches conducted by biologists, and standardized information on each nest was collected following protocols of the Arctic Shorebird Demographic Network (Brown et al. 2014).

Elemental compositions are reported for the fine fraction of surface sediments from Bellingham Bay (June 2017 and March 2019) and in the fine fraction of streambank sediment from the Nooksack River (September 2017, March 2019, September 2019), Squalicum Creek (March and September 2019), Whatcom Creek (March and September 2019), and Padden Creek (March and September 2019). Major oxide percentages a

These data are in two tables relating to fall age ratios (number of juvenile birds : total birds aged) of Black brant (Branta bernicla nigricans) staging in Izembek Lagoon, Alaska since 1963. The first file is observation data for the birds' age classes during surveys and associated survey characteristics. The second file contains model-based estimates of age ratios by year along with SE, and 95%

This dataset consists of several measures of landscape characteristics, each of which is summarized from raster data within spatial polygons. These spatial polygons represent the land area upstream of sampled stream reaches. These stream reaches were sampled by the Maryland Department of Natural Resources for the Maryland Biological Stream Survey program during survey rounds one, two, and four. La

Remotely sensed imagery is increasingly used by emergency managers to monitor and map the impact of flood events to support preparedness, response, and critical decision making throughout the flood event lifecycle. To reduce latency in delivery of imagery-derived information, ensure consistent and reliably derived map products, and facilitate processing of an increasing volume of remote sensing da

These data are in one table with age and sex composition counts of groups of walruses on ice floes in the northern Bering and Chukchi Seas. Counts were collected by visual observations from boats.

This dataset includes raw and rinex data from 2019 campaign gps data from the Island of Hawai'i in 2019. There were a total of 69 sites occupied. All data is included along with metadata, log sheets and raw/rinex data.

This data release contains the whole-rock major and trace element analyses of 51 samples of intrusive igneous rocks from the Wet Mountains area of Custer and Fremont counties of south-central Colorado, collected by U.S. Geological Survey (USGS) geologists. The samples were collected from breccias, veins and thin dikes, and a variety of carbonatite, felsic, mafic, and ultramafic intrusions across

The distribution of permafrost in cold regions is subject to temporal and spatial changes influenced by climate, landscape disturbance, and ecosystem succession. Remote sensing from airborne and satellite platforms is increasing our understanding of landscape-scale permafrost distribution, but typically lacks the resolution to characterize finer-scale processes and phenomena, which are often bette

The surface ecology of small ocean islands is directly linked to subsurface fresh water resources, which exist in the form of soil water and fresh groundwater lenses. The management of threaten plant species such as the tree Pisonia grandis needs to consider the spatial and temporal dynamics of groundwater lenses, particularly in a time of climate change.
