These measurements were conducted to assess how rapid desiccation, a similar phenomenon happening to inland lakes globally, is affecting biogeochemical cycling in the lake (Yousavich et al., 2026). All measurements were conducted between 2020 and 2023, with samples collected aboard a small boat during four sampling campaigns (January 2020, August 2020, September 2021, and November 2023). Water column samples were collected with either a Niskin bottle (2020-2022) or a peristaltic pump (2023). Methane oxidation and denitrification rates were only measured in samples from the 2023 campaign.-115.96-115.7433.2633.44National Aeronautics and Space Administrationhttps://doi.org/10.13039/10000010480NSSC21K0594Alternative Earths – How to Build and Sustain a Detectable Biosphere
