2010-2011 Science Planning Summary Project Detail
Impact of recent climate warming on active-layer dynamics, permafrost, and soil properties on the western Antarctic Peninsula
The Neumayer Channel is 16 miles long, separating Anvers Island from Wiencke Island and Doumer Island, in the Palmer Archipelago. This channel was oirginally named the Roosen Channel by a German expedition in the 1870s. It was later named for Georg von Neumayer by the Belgian Antarctic Expedition, 1897-99.

Project Description:
This is a three-year collaborative project with CALM (Circumpolar Active Layer Monitoring, funded in part by a grant from the NSF’s Arctic Research and Logistics program) and PERMANTAR (Permafrost and Active Layer Monitoring in the Maritime Antarctic, funded by Portuguese and Spanish programs). Researchers will establish permafrost and soil monitoring stations on Livingston and Deception Islands, at Palmer Station, and on an island site (to be selected) between Palmer Station and Livingston Island. Soil and permafrost are sensitive indicators of climate change and these new sites are particularly significant because recent climate change is exceptionally evident here. Each soil-climate/active-layer monitoring station comprises an array of shallow boreholes with sensors that record soil temperatures year-round. Permafrost is monitored through a 10-15-meter-deep borehole.

Field Season Overview:
In this initial field season, soil and permafrost monitoring stations will be established in the vicinity of Palmer Station and at Brabant Island or a nearby island site as part of the Southern Hemisphere CALM grid. The PI will travel via PERMANTAR logistics to assist at the PERMANTAR sites on Deception and Livingston Islands, and then return to South America. Following this deployment, the PI and two students will deploy to Palmer Station on cruise LMG11-03 to establish soil-climate and active-layer monitoring stations in the proximity of the station. The active-layer monitoring station will involve the drilling of an array of shallow boreholes to deploy sensors that will record soil temperatures on a regular basis. The three-person team will return to Punta Arenas on cruise LMG11-04.
