Science Summary: The PI will continue efforts at Store Glacier in Greenland. A major west Greenland outlet to the inland ice sheet, Store Glacier produces ~14–18 cubic km of ice per year, flowing at a speed of 4.2–4.9 km, second only in output to Sermeq Kujaleq (a.k.a. Jakobshavn Glacier) east of Ilulissat (Weidick and Bennicke, 2007). Store glacier undergoes mid-summer deceleration likely related to the effects of subglacial meltwater and drainage system processes; data suggest that drainage of supraglacial lakes and water-filled crevasses results in a 40–60% mid-summer speed decrease (Howat et al. 2010).
Building on field campaigns in 2008, 2009, and 2010, the PI will conduct a "holistic" study of ice-ocean-climate interactions, combining observations from oceanographic sensors; on-ice continuous GPS; automatic weather stations (AWS); time lapse cameras; tide gauges; and aircraft and satellite remote sensing. The work is a collaboration between Byrd Polar Research Center and UK collaborators from U. Wales Aberystwith and St. Andrews, Scotland.
Logistics Summary: The project, a collaboration between the PI (OSU) and British collaborators, is a holistic effort to study ice-ocean-climate interactions around Greenland’s Store Glacier and the Ikerasak Fjord. The 2012 field campaign, organized in three phases, will use oceanographic sensors; on-ice continuous GPS; automatic weather stations (AWS); time lapse cameras; tide gauges; and aircraft and satellite remote sensing.
Phase 1 work will begin in late May with the installation of on-ice continuous GPS, tide gauges, time lapse cameras (to capture major calving events), an on-ice automatic weather station, and potentially seismometers.
Phase 2 efforts will involve on-ice camping in late June to support the installation of in-situ strain gauges and flooded crevasse water-level loggers. The researchers will spend about a week at the camp to conduct more detailed crevasse strain observations.
During Phase 3, in July, the team will make intensive marine observations aboard the Research Vessel Gambo, which will bring British researchers to make repeat surveys of the sub-marine vertical ice cliff at the glacier front. The researchers intend that the survey effort will establish submarine melting and calving rates. R/V Gambo will also support CTD casts in chains along the Store Glacier front and along Ikerasak Fjord. Finally, researchers will install two automatic weather stations near water level, one on an island 8 km in front of Store Glacier.
CPS will provide Air National Guard (ANG) coordination between Scotia, NY, and Kangerlussuaq for the PI and his cargo. The NSF will recoup the costs of this support directly with the PI's institute. The PI will arrange for all other logistics in and outside of Kangerlussuaq and pay for them from the grant.
