EXO2 surface-water-quality data at unnamed north lake near Bemidji, Minnesota, 2019

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-09-21T00:00:00Z
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 includes 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_North.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 EXO2_SWQ_North_shapefile.zip.
