Velocity and Bathymetry Surveys of the Columbia River near Northport, Washington, May 2018

Scott W. Anderson & Nick Elwell
Boat-mounted acoustic doppler current profilers (ADCPs) were used to collect velocity data on the Columbia River in a small area near Northport, WA. Velocity surveys were collected during two surveys at high-flow, high-stage conditions in May 2018. Bathymetric data were also collected during one of the surveys using a single-beam echo-sounder. The datasets here provide 1) raw ADCP and single-beam survey data, 2) processed summaries of the data, primarily in geospatial data formats, and 3)...

Organic matter decomposition along coastal wetland landscape gradient from tidal freshwater forested wetland to oligohaline marsh in Southeastern U.S.A. (2010-2011)

Camille L. Stagg, Donald R. Schoolmaster, Ken W. Krauss, Nicole Cormier & William H. Conner
Coastal wetlands significantly contribute to global carbon storage potential. Sea-level rise and other climate change-induced disturbances threaten coastal wetland sustainability and carbon storage capacity. It is critical that we understand the mechanisms controlling wetland carbon loss so that we can predict and manage these resources in anticipation of climate change.

Breeding bird species in peatland habitats, Seney NWR, 2007-2009

Jane E. Austin
The avian community of peatland habitats were surveyed along belt transects established in multiple units of Seney National Wildlife Refuge, representing peatland habitats dominated by a range of sedge to shrub cover at varying levels. Surveys were conducted during the 3-week period of mid-May to early June and again during mid-June-early July in three years (2007-2009). Three datasets are included here 1) data of presence/absence of breeding bird species detected in each 100-m segment of...

Ozark aquifer regional potentiometric surface dataset in, Arkansas, Kansas, Missouri, and Oklahoma, November 2014-January 2015

Anna M. Nottmeier
This dataset represents synoptic data and conditions of water levels of the Ozark aquifer as documented in the U.S. Geological Survey Scientific Investigations Map 3348 (https://pubs.er.usgs.gov/publication/sim3348). The Ozark aquifer, within the Ozark Plateaus aquifer system, is the primary groundwater source in the Ozark Plateaus physiographic province. The construction of a regional potentiometric-surface map of the Ozark aquifer is needed to aid assessment of current and future groundwater use and availability. The regional potentiometric-surface mapping is...

33 high-resolution scenarios of land use and vegetation change in the Upper Missouri River Basin

Terry L Sohl, Dornbierer, Jordan (Contractor) M & Wika, Steve (Contractor)
A new version of USGS's FORE-SCE model was used to produce unprecedented landscape projections for the Upper Missouri River Basin region of the northern Great Plains. The projections are characterized by 1) high spatial resolution (30-meter cells), 2) high thematic resolution (29 land use and land cover classes), 3) broad spatial extent (covering approximately 516,000 square kilometers), 4) use of real land ownership boundaries to ensure realistic representation of landscape patterns, and 5) representation of...

Julie Prior-Magee & Alexa McKerrow
This dataset represents a species habitat distribution model for Baird's Sparrow. These habitat maps are created by applying a deductive habitat model to remotely-sensed data layers within a species' range.

Coral cores collected in Dry Tortugas National Park, Florida, U.S.A.: Photographs and X-rays

Jennifer A. Flannery, Christopher D. Reich, Lucy A. Bartlett, Michael S. Weinzierl & Ilsa B. Kuffner
Cores from living coral colonies were collected from Dry Tortugas National Park, Florida, to obtain skeletal records of past coral growth and allow geochemical reconstruction of environmental variables during the corals centuries-long lifespans. The samples were collected as part of the U.S. Geological Survey (USGS) Coral Reef Ecosystems Studies project (http://coastal.er.usgs.gov/crest/) that provides science to assist resource managers tasked with the stewardship of coral reef resources. Three colonies each of the coral species Orbicella faveolata...

Acoustic backscatter - Data and Python Code

Daniel D Buscombe, Paul E Grams & Matthew A Kaplinski
These data were compiled for investigating the relationship between acoustic backscattering by riverbeds composed of various riverbed substrates (bed sediment), and for developing and testing a probabilistic model for substrate classification based on high-frequency multibeam acoustic backscatter. The model is described in Buscombe et al. (2017). The data consist of various quantities on coincident grids, from various sites along the Colorado River in Grand Canyon, including water depth, bed roughness, the area (or footprint) of...
