<Reference>Yousavich, David; Diamond, Charles; Hung, Caroline; Vetushko, George; Peng, Xuefeng; Lyons, Timothy W; Treude, Tina (2026): Biogeochemical processes in a rapidly drying inland lake, the Salton Sea. Journal of Great Lakes Research, 102884, https://doi.org/10.1016/j.jglr.2026.102884</Reference>
<Summary>The following dataset includes water column microbial metabolic rates for the Salton Sea, a rapidly drying inland lake in California's Coachella Valley. 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. ** For all details see the full metadata description at "https://doi.pangaea.de/10.1594/PANGAEA.996715"!</Summary>
