The Antarctic tundra, dominated by non-vascular photoautotrophs (NVP) like mosses and lichens, serves as a vital habitat for sea animals, which contribute organic matter and oceanic sulfur to the land, potentially influencing sulfur transformations. Here, we measured OCS fluxes from the Antarctic tundra and linked them to soil biochemical properties. This dataset therefore is collected from these experiments. It includes the figure source data associated with a peer-reviewed publication that is currently under review. Once the manuscript is published, the URL and DOI number will be provided here and this description will be updated accordingly. Results revealed that the NVP-dominated upland tundra acted as an OCS sink (-1.0 ± 0.6 pmol m -2 s -1 ), driven by NVP and OCS-metabolizing enzymes from soil microbes (e.g., Acidobacteria , Verrucomicrobia , and Chloroflexi ). In contrast, tundra within sea animal colonies exhibited OCS emissions (1.4 ± 0.4 pmol m -2 s -1 ), resulting from the introduction of ...
