Drilling and installation of boreholes for permafrost thermal monitoring on Livingston Island in the maritime Antarctic


Ramos, M; Hasler, A; Vieira, G; Hauck, C; Gruber, S (2009). Drilling and installation of boreholes for permafrost thermal monitoring on Livingston Island in the maritime Antarctic. Permafrost and Periglacial Processes, 20(1):57-64.

Abstract

Three new boreholes up to 25 m deep were drilled on Mount Reina Sofía (275 m a.s.l.), Livingston Island, where previous near-surface temperature measurements (mean annual ground temperatures of -2.1 to -2.6°C) have indicated the presence of permafrost. A thermistor chain and logging system were installed in the deepest borehole, while the others were equipped with individual miniature temperature loggers (iButtons). Initial data from the 25 m borehole indicates a permafrost body several decametres thick. Future data from these boreholes are expected to provide insight into ground temperature evolution in maritime Antarctica. Copyright © 2009 John Wiley & Sons, Ltd.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
