2018-2019 USAP Field Season
Characterization of upstream ice and firn dynamics affecting the South Pole Ice (SPICE) core
Dr. Michelle R Koutnik
Supporting Stations: McMurdo Station, South Pole Station
Ice-core records are critical to understanding past climate variations. Analysis of an Antarctic ice core recently drilled at the South Pole will allow detailed investigation of atmospheric gases and fill an important gap in understanding the pattern of climate variability across Antarctica. Critical to the interpretation of any ice core are: (1) accurate chronologies for both the ice and the trapped gas; and (2) demonstration that records from the ice core reliably reflect climate. The data collected from this team's research, now in its fourth and final season, will improve the ice and gas chronologies by making measurements of snow compaction in the upstream catchment in order to constrain age models of the ice. These measurements will help to better understand and predict time-varying conditions in the upper part of the ice sheet.
Field Season Overview
Four participants will prepare in McMurdo Station for about one week before heading to South Pole Station where they will spend about two weeks. They will be based out of South Pole Station and at their tent camp 50 km from station where instruments were installed in previous seasons. Two team members will conduct GPS and radar surveys by snowmobile along transects radiating out up to 100km from South Pole. They will tow a Conestoga for shelter during these day trips. The other two team members will stay at the camp to perform instrument maintenance and borehole logging.
