A long-term soil manipulation experiment has been conducted as part of the McMurdo Dry Valleys Long Term Ecological Research (LTER) project. This table contains hourly soil temperature measurements associated with the long-term manipulation experiment on the south side of Lake Hoare, Taylor Valley, Antarctica.

https://mcm.lternet.edu/content/soil-long-term-manipulation-experiment-soil-temperatures-hourly Lake Hoare occupies a narrower portion of the Taylor Valley, dammed by the Canada Glacier. It would drain almost completely without this dam. There are a number of islands which may be related to an old terminal of Canada Glacier. The lake is fed primarily from direct runoff from the glacier, as well as meltwater streams. (Lake level rose ~1.5 m between 1972 and 1996). There are no surface outflows; the only known water loss is through ice ablation (evaporation, sublimation and physical scouring).

To increase soil temperature, an open-top ITEX cone chamber (0.44m2 footprint) was placed over the plot. Chamber was made of 1-mm thick Sun-Lite HP fiberglass (Solar Components Corp., Manchester, NH, USA). Temperature probes were placed at 3 depths: surface, 5 cm, and 10 cm both inside (“Chamber”) and outside (“Open”) the chamber. Temperatures were calculated from voltages collected by a Campbell CR10 data logger. Data were downloaded in January of each year.
