A vented water-level logger was installed at site MC1 (N 47° 05’ 12.2”/W 122° 43’ 36.8”) and continuously measured water depth and temperature at 15-minute intervals from Nov 22, 2016 to Sept 6, 2017 (288 days). This site is tidally influenced and located 1.12 km from the mouth of McAllister Creek. Elevation (NAVD88) of the water surface above the sensor was surveyed by RTN-GPS. The offset to convert all water depth time-series data to water surface elevation (NAVD88) is -1.052 m. Water depth ranged from 0.69 to 4.88 m. Temperature ranged from 2.8 to 22.5 degrees C.

This data set provides locations and values of water quality parameters from a survey conducted on August 24, 2016 using an Autonomous Underwater Vehicle (AUV) in Nicoll Bay, NY. During the August 24 survey, 17,808 observations of water quality parameters were made. Parameters collected include dissolved oxygen, pH, water temperature, specific conductance, and salinity. Data was collected in approximately east-west transects by the AUV, with the northern-most transects made first. Data was collected between the hours of 1 am and 5 am to obtain minimum DO values in the daily cycle. There are three files available for download in the 'Attached Files' section below. There is a zip file which contains the observation...

The U.S. Geological Survey, in cooperation with the Alaska Department of Natural Resources Division of Mining, Land, and Water, has released a geologic map of the Big Delta B-1 quadrangle of east-central Alaska (Day and others, 2007). This companion report presents the major element oxide and trace element geochemical analyses, including those for gold, silver, and base metals, for representative rock units and for grab samples from quartz veins and mineralized zones within the quadrangle. Also included are field station locations, field notes, structural data, and field photographs based primarily on observations by W.C. Day with additions by J.M. O'Neill and B.M. Gamble, all of the U.S. Geological Survey. The...

The Yukon River basin is a vast and diverse ecosystem covering more than 330,000 square miles, an area larger than Texas. Approximately 126,000 people live within the basin and depend on the Yukon River and its tributaries for drinking water, commerce, and recreational and subsistence fish and game resources. Much of the Yukon River basin is underlain by permafrost containing vast amounts of organic carbon and nutrients. Recent climatic warming of the basin has resulted in lengthening of the growing season, melting of permafrost, deepening of the soil active layer, drying of upland soils, and shrinking of wetlands. These mostly terrestrial effects also affect the hydrology of the basin, changing the timing, magnitude,...

The development and deployment of digital broadband seismographs provides the data required to rapidly assess earthquake size, determine source parameters and better characterize ground motions affecting earthquake hazard. The focus of regional moment tensor analysis is to estimate the moment magnitude, faulting parameters and source depth of earthquakes that are too small to be recorded teleseismically. Thus they have the potential of extending the earthquake catalog to magnitudes less than about M4-4.5. This data distribution provides the details required to critically review the resulting catalog, e.g., the waveforms used, processing parameters and velocity model. In addition the issue of the correct local magnitude...

This data, grsg_lcp_ThiessenPoly_mst3, is one of five hierarchical delineations of greater sage-grouse population structure. The data represent Thiessen polygons of graph constructs (least-cost path minimum spanning tree [LCP-MST]) that defined our population structure of sage-grouse breeding sites in the western United States. This data was developed by applying dispersal and genetic rules to decompose the fully connected population structure (graph) into the product presented here. Understanding wildlife population structure and connectivity can help managers identify conservation strategies, as structure can facilitate the study of population changes and habitat connectivity can provide information on dispersal...

A cells polygon feature class was created by the U.S. Geological Survey (USGS) to illustrate the degree of exploration, type of production, and distribution of production in the State of Kentucky. Each cell represents a quarter-mile square of the land surface, and the cells are coded to represent whether the wells included within the cell are predominantly oil-producing, gas-producing, both oil and gas-producing, or the type of production of the wells located within the cell is unknown or dry. Data were retrieved from the Kentucky Oil and Gas Well Records database and saved as a shapefile of oil and gas well locations for Kentucky. Cells were developed as a graphic solution to overcome the problem of displaying...

History and Introduction This portion of the RASS database contains geochemical data for Alaska produced by the analytical laboratories of the Geologic Division of the U.S. Geological Survey (USGS). The data represent analyses of stream-sediment, heavy mineral concentrate, soil, and organic material samples. Most of the data comes from mineral resource investigations conducted in the Alaska Mineral Resource Assessment Program (AMRAP). However, some of the data were produced in support of other USGS programs. The data were originally entered into the in-house Rock Analysis Storage System (RASS) database. The RASS database, which contains over 580,000 data records, was used by the Geologic Division from the early...

We identified a set of cores for each species that include areas of high relative value to the species either in the present, the future, or both. We assessed and mapped the connections between each nearby pair of cores (both in the future and present) and used the pairwise connectivities to assemble a graph of connections and to score each core’s connectivity in the present and future. Finally, we created an overall score that combines the landscape capability value, the climate refugia value, and the connectivity of each core which we think is a good starting point for conservation of each species. In general we found that the highest habitat values, connectivity, and scores were concentrated both towards the...

This data release contains coastal wetland synthesis products for the state of Maine. Metrics for resiliency, including the unvegetated to vegetated ratio (UVVR), marsh elevation, tidal range, and lifespan, are calculated for smaller units delineated from a digital elevation model, providing the spatial variability of physical factors that influence wetland health. The U.S. Geological Survey has been expanding national assessment of coastal change hazards and forecast products to coastal wetlands with the intent of providing federal, state, and local managers with tools to estimate the vulnerability and ecosystem service potential of these wetlands. For this purpose, the response and resilience of coastal wetlands...

Note: The 2021 data release "Geospatial characterization of salt marshes for Massachusetts" is a more recent and comprehensive MA salt marsh dataset. (https://doi.org/10.5066/P97E086F) Unvegetated to vegetated marsh ratio (UVVR) in the Cape Cod National Seashore (CACO) salt marsh complex and approximal wetlands is computed based on conceptual marsh units defined by Defne and Ganju (2019). UVVR was calculated based on U.S. Department of Agriculture National Agriculture Imagery Program (NAIP) 1-meter resolution imagery. Through scientific efforts initiated with the Hurricane Sandy Science Plan, the U.S. Geological Survey has been expanding national assessment of coastal change hazards and forecast products to coastal...

Note: The 2021 data release "Geospatial characterization of salt marshes for Massachusetts" is a more recent and comprehensive MA salt marsh dataset. (https://doi.org/10.5066/P97E086F) The salt marsh complex of Cape Cod National Seashore (CACO), Massachusetts, USA and approximal wetlands were delineated to smaller, conceptual marsh units by geoprocessing of surface elevation data. Flow accumulation based on the relative elevation of each location is used to determine the ridge lines that separate each marsh unit while the surface slope is used to automatically assign each unit a drainage point, where water is expected to drain through. Through scientific efforts initiated with the Hurricane Sandy Science Plan,...
