A comprehensive inventory of perennial snow and ice in Glacier National Park in 2005 A comprehensive inventory of perennial snow and ice in Glacier National Park in 2005
These polygon features represent a comprehensive inventory of perennial snow and ice on the landscape in Glacier National Park (GNP) in 2005. The imagery used to delineate perennial snow and ice was taken late season, therefore, all snow and ice present on the landscape is assumed to be perennial. Whether each polygon is "perennial snow and ice" or "active glacial ice" is included...
Kentucky Drought Condition Monitor Kentucky Drought Condition Monitor
The Ohio-Kentucky-Indiana WSC/Kentucky Agricultural Development Board choose four parameters to monitor drought: precipitation, streamflow, groundwater level, and crop moisture index. These parameters are frequently used by the Kentucky Drought Mitigation and Response Plan (2008) as indicators of the four stages of drought: drought advisory, moderate drought, severe drought, and extreme...

This data release contains estimated daily streamflow values for 9,203 12-digit hydrologic unit codes (HUC12s) in the southeastern United States for the period 1950-2009. The files are provided in text format, which can be used in R and in other programs. The 'Site Info' folder contains 18 files with streamgage information and the 'Daily Values' folder contains 18 files with predicted...
Detection of invasive aquatic plants Myriophyllum spicatum and Egeria densa in lakes using eDNA, field and mesocosm data Detection of invasive aquatic plants Myriophyllum spicatum and Egeria densa in lakes using eDNA, field and mesocosm data
We conducted a study to test the factors related to detectability of two invasive aquatic plants (Egeria densa and Myriophyllym spicatum) using environmental DNA (eDNA), over extended periods of time, and specifically examined how plant growth stage and abundance relates to eDNA detection in semi-natural and natural conditions. This dataset is from sampling performed in summer of 2018 in...
Rapid assessment test strip data for determining cyanotoxin presence in algal blooms, Kabetogama Lake, northern Minnesota, 2017-2018 Rapid assessment test strip data for determining cyanotoxin presence in algal blooms, Kabetogama Lake, northern Minnesota, 2017-2018
Algal toxins are a growing concern worldwide. Rapid assessment test strips are a newer technology and their accuracy in detecting toxins in different lakes with different phytoplankton and toxins present is unknown. This data release is supported by our testing of toxin test strips. This research took place in Voyageurs National Park in northern Minnesota. The research will indicate...
Microbial Communities Associated with Hot Springs and other CO2-rich Waters, Rocky Mountain Plateau Microbial Communities Associated with Hot Springs and other CO2-rich Waters, Rocky Mountain Plateau
The Colorado Plateau is associated with several different commercial sources of natural CO2 and other non-hydrocarbon gases, such as noble gases. Twenty-five different hot springs, warm springs, cold springs, and/or rivers across the Utah region of the Colorado Plateau were sampled for microbial biomass. These different locations were associated with some concentration of dissolved or
Low biomass microbiology samples collected from a hydraulically fractured well producing from the Niobrara Shale in Colorado Low biomass microbiology samples collected from a hydraulically fractured well producing from the Niobrara Shale in Colorado
Low biomass waters provide a unique challenge in the field of microbial ecology. It is difficult to determine, when biomass concentrations are extremely low, whether or not the sequencing data received are of good quality and representative of the waters sampled. Fifty-nine samples including 8 blanks were collected from a low biomass hydraulically fractured well producing from the...
Coastal Bathymetry Data Collected in August 2018 from the Chandeleur Islands, Louisiana Coastal Bathymetry Data Collected in August 2018 from the Chandeleur Islands, Louisiana
Scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida (USGS-SPCSMC), conducted a bathymetric survey of the Northern Chandeleur Islands, in August 2018. During this study, multibeam bathymetry data were collected aboard the research vessel (R/V) Sallenger, while single-beam bathymetry data were collected aboard the R/V Jabba...

Data release consists of five comma delimited text files containing discharge and sediment data for five gaged tributaries to the Anacostia River in Washington, District of Columbia. Data were collected from 2003 through 2018.
Microbial communities and bacterial indicators for shoreline sand, sediment, and water in Racine, Wisconsin; Chicago, Illinois; and East Chicago, Indiana; 2016-2017 Microbial communities and bacterial indicators for shoreline sand, sediment, and water in Racine, Wisconsin; Chicago, Illinois; and East Chicago, Indiana; 2016-2017
The data associated with the following data release were collected between 2016 and 2017 at three locations on Lake Michigan: Racine, WI; Chicago, IL; and East Chicago, IN. Individual water samples were collected one day a week for ten weeks between June and August. Samples were collected from eight specific sites made up of two river and six shoreline type environments. Sampling was...
