Environmental DNA and qPCR data for an algal bloom in Kabetogama Lake, northern Minnesota, 2023 Environmental DNA and qPCR data for an algal bloom in Kabetogama Lake, northern Minnesota, 2023
This data release provides phytoplankton and fish environmental DNA (eDNA) and cyanotoxin biosynthesis gene abundance data from an algal bloom at Ash River Boat Docks on Kabetogama Lake (USGS site ID 482603092511801) collected between September 12 and September 13, 2023. Algal bloom samples were collected every three hours over a 24-hour period at two sites, one at the end of a dock and...
Cyanobacteria identification and enumeration data at Ash River Boat docks, Kabetogama Lake, northern Minnesota, 2022 Cyanobacteria identification and enumeration data at Ash River Boat docks, Kabetogama Lake, northern Minnesota, 2022
This data release provides cyanobacteria identification and enumeration data at Ash River Boat Docks on Kabetogama Lake (USGS site ID 482603092511801) collected in 2022. Sixteen environmental samples and four quality assurance replicates were collected from two locations, one at the end of the dock and one at the shoreline, between September 21, 2022 and September 22, 2022.
Airborne electromagnetic and magnetic survey results from the Upper San Pedro Basin, Arizona, 1997 and 1999 Airborne electromagnetic and magnetic survey results from the Upper San Pedro Basin, Arizona, 1997 and 1999
Airborne electromagnetic (EM) and magnetic survey data were collected by GeoTerrex Ltd. in the Upper San Pedro Basin and Fort Huachuca, Arizona in 1997 and 1999. EM data were collected using a time-domain GEOTEM system towed behind a fixed-wing aircraft with 30Hz cycle rate, 696,000 Am2 dipole moment, and 4 ms pulse width. Magnetic data were collected using a CS-2 cesium vapor...
North River Gameland, North Carolina Myotis septentrionalis Day-roosts North River Gameland, North Carolina Myotis septentrionalis Day-roosts
These data contain located day-roosts for the northern long-eared bat (Myotis septentrionalis) at the North River Game Land, North Carolina in May and June of 2019. Data contained include individual bat tracked, date day-roost was found, day-roost unique ID, geographic coordinates of day-roost, tree species of day-roost, diameter breast height (cm) of day-roost, day-roost decay-stage...
Aerial imagery, digital elevation model, orthomosaic image, ground control points, and bathymetry survey points collected in 2019 to identify sources of water and salts for the Zuni Salt Lake in west-central New Mexico, United States Aerial imagery, digital elevation model, orthomosaic image, ground control points, and bathymetry survey points collected in 2019 to identify sources of water and salts for the Zuni Salt Lake in west-central New Mexico, United States
Aerial imagery was collected with an uncrewed aerial system (UAS) and ground control points were used to construct a digital elevation model (DEM) and orthomosaic image using Structure-from-motion (SfM) photogrammetry for the Zuni Salt Lake in west-central New Mexico. The DEM and bathymetry survey points were combined to estimate lake water volume as a function of lake stage in the U.S...
Hard shoreline structure inventory for states along the Atlantic and Gulf Coasts Hard shoreline structure inventory for states along the Atlantic and Gulf Coasts
To support the development of more accurate hurricane coastal impact models, we created a dataset containing an inventory of information sources of hard shoreline structures — including seawalls, groins, bulkheads, and breakwaters — for each U.S. state along the Gulf of America and Atlantic coasts. The shoreline structure inventory was developed initially from internet searches of open...
