Linear regression models were developed using specific conductance to estimate chloride concentrations at stream and storm sewer sites monitored by the Upper Midwest Water Science Center (UMidWSC) for UMidWSC stakeholders. Methods for model development, application, and maintenance are described in Standard Operating Procedures for Computing Chloride Concentrations and Loads at Sites...

Large wood is an important part of ecosystem functions in rivers around the world, including serving as fish habitat, providing nutrient sources, and contributing to geomorphic processes. This dataset was produced to support the study of large wood dynamics in Pool 8 of the Upper Mississippi River System. The dataset contains 60 polygons located along shoreline of the main channel, side...

Lidar data is remotely sensed high-resolution elevation data collected by an airborne collection platform. Using a combination of laser range-finding, GPS positioning and inertial measurement technologies; Lidar instruments are able to make highly detailed Digital Elevation Models (DEMs) of the earth's terrain, man-made structures and vegetation. Breaklines are used in surface models to...

This dataset includes freshwater drum age data from five study reaches of the Mississippi River and one study reach from the Illinois River as presented in the manuscript Life history traits and population dynamics of Freshwater Drum across large river gradients. Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S...

This exploratory study examined vegetation changes in agricultural fields using imagery analysis in the surface areas overlying the Flaxville aquifer and other aquifers in Montana from 1990 to 2020. Agricultural fields were manually digitized and can be found in flaxville_ag_fields.shp. This analysis used surface reflectance data from Landsat satellites to calculate the 95th percentile...

This data release presents computed tomography (CT) imagery generated from coral core samples curated within the U.S. Geological Survey (USGS) Coral-Core Archive. These data were collected as part of ongoing USGS coral-reef research activities and include samples originating from multiple locations and collection efforts. A Geotek Rotating X-ray CT (RXCT) system was used to acquire x-ray...

Two digital video cameras (CACO-01 c1 and c2) were installed at Head of the Meadow Beach, Cape Cod National Seashore in Massachusetts (MA) as part of a U.S. Geological Survey (USGS) research project to study the beach and nearshore environment. The cameras were located near the top of the 18 meter high bluff and faced north-east (c1) and east (c2) along the beach. They ran from December...

Imagery Data System for accessing CoastCam images for CACO-01 at Head of the Meadow Beach on Cape Cod National Seashore

This volume's release consists of 139985 media files captured by autonomous wildlife monitoring devices under the project, USGS Cuban Treefrog Invasion Front. The attached files listed below include several CSV files that provide information about the data release. The file, "media.csv" provides the metadata about the media, such as filename and date/time of capture. The actual media...

The U.S. Geological Survey (USGS) Water Mission Area (WMA) - Ecosystems Mission Area (EMA) EcoDrought project is comprised of interdisciplinary teams across the United States focused on the nexus between drought and ecosystem processes. To characterize streamflow conditions in EcoDrought study areas, gage height (stage) and water temperature data were collected using submersible pressure
