Rethinking climate change impacts on subsurface temperatures in a sub‐Antarctic mire affected by synoptic scale processes
Abstract This paper presents the first high resolution temperature data from a small Agrostis magellanica mire on subantarctic Marion Island as part of an ongoing island‐wide monitoring project on subsurface ground temperature variability. Variations in ground temperatures were found to be directly...
