EXO2 vertical point water-quality measurements at unnamed north lake near Bemidji, Minnesota, 2019

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 when turbidity was [...]
