Oxygen, nitrogen, and argon gas in Deming Lake, MN

Deming Lake is a meromictic, ferruginous lake located in Itasca State Park, Minnesota, USA. This dataset includes measurements of nitrogen/argon (N2/Ar) and oxygen/argon (O2/Ar) gas ratios as well as O2 and Ar concentrations measured through four depths within the photic zone of the lake in August 2023 using membrane inlet mass spectrometry (MIMS). This data can be used to calculate N2/Ar and O2/Ar saturation ratios to determine where there is net consumption or production of N2 and O2 gas.
