These data were collected in coordination with the U.S. Geological Survey Hydrogeophysics Branch for the National Crude Oil Spill Fate and Natural Attenuation Research Site. Water quality data were collected using an Ecomapper Autonomous Underwater Vehicle (AUV) and measured parameters include temperature, specific conductance, salinity, water density, pH, dissolved oxygen, total chlorophyll, and blue-green algae. These data are provided in two formats: a CSV file named AUV_WQ_South.csv, and in the Environmental Systems Research Institute (ESRI) shapefile format consisting of a group of files that have been compressed into a zip archive that is named AUV_WQ_South_shapefile.zip.
These data were collected in coordination with the U.S. Geological Survey Hydrogeophysics Branch for the National Crude Oil Spill Fate and Natural Attenuation Research Site. Data were collected while trailing the Ecomapper with an EXO2 multi-parameter sonde suspended at the water surface from a manned boat propelled by a trolling motor. An EXO 2.0 handheld controller was used for coordinate information. Data collected inlcludes barometric pressure, water temperature, specific conductance, pH, dissolved oxygen, total chlorophyll, and blue-green algae. These data are provided in two formats: a CSV file named EXO2_SWQ_South.csv, and in the Environmental Systems Research Institute (ESRI) shapefile format consisting...

These data were collected in coordination with the U.S. Geological Survey Hydrogeophysics Branch for the National Crude Oil Spill Fate and Natural Attenuation Research Site. Data were collected using an EXO2 suspended 5.5 feet below a kayak. Sensor was dragged along the bottom of the lake except in instances where water depth was greater than 5.5 ft. The continuous profiling was conducted while paddling a kayak using Hypack 2017a to navigate survey lines set on a georeferenced background map to the best of ability. An EXO 2.0 handheld controller was used for coordinate information. Data collected includes, water temperature, specific conductance, pH, dissolved oxygen, and turbidity. These data are provided in two...
These data were collected in coordination with the U.S. Geological Survey Hydrogeophysics Branch for the National Crude Oil Spill Fate and Natural Attenuation Research Site. An EXO2 multi-parameter sonde was used to vertically characterize water quality at point locations around the perimeter of the north unnamed lake, and in area of the lake suspected to contain a hydrocarbon plume. Measurements were taken from a kayak using Hypack 2017a to navigate and set target points. Data collected includes barometric pressure, dissolved oxygen, specific conductance, turbidity, pH, and water temperature. At each location and specific depth there were typically multiple measurements made, especially in the organic sediments...
The National Crude Oil Spill Fate and Natural Attenuation Research Site is located near where about 1.7 million liters of crude oil spilled in 1979. Much of the oil spill leached into groundwater which flows towards an unnamed lake at the site. The U.S. Geological Survey Branch of Hydrogeophysics has been working to map the plume's extent on land and into the lake using a variety of geophysical techniques. In 2018, the group was able to map a group of anomalies within the lake consisting of elevated specific conductance concentrations. It was determined that these specific conductance anomalies were likely attributed to hydrocarbon plumes leaching into the lake. In 2019, the U.S. Geological Survey Central Midwest...
