Glaciology

Initial landing on iceberg B15A.

Initial landing on iceberg B15A (logistic support provided by the U.S. National Science Foundation) to install automated weather stations and iceberg-drift tracking stations.

Rift camera at Nascent Iceberg Site on Ross Ice Shelf, Antarctica

Time-lapse photography created by automatic camera located on the edge of a large rift on the Ross Ice Shelf, Antarctica.

Glaciers and lakes in Antarctica's Dry Valleys

Glaciers and pro-glacial lakes in Antarctica's Dry Valley region.

Graduate students and faculty advisor in Antarctica taking a trip to Windless Bight

Graduate student and faculty research team in Antarctica preparing to travel to Windless Bight, near Ross Island, to test iceberg-sounding radar.

Faculty sleeping hole in snow-school near Ross island, Antarctica

Faculty sleeping quarters during survival training school near McMurdo Station, Antarctica.

Graduate student standing next to Twin Otter Aircraft

Graduate student and Twin Otter aircraft on Ross Ice Shelf. Seismometers deployed during this mission reveal how ocean swell influences the iceberg calving margin of Antarctica.

Investigation of sea ice properties

Field investigation of snow/sea-ice interaction in McMurdo Sound, Antarctica.

Approaching iceberg B15A in the Ross Sea aboard a USCG icebreaker

The United States Coast Guard icebreaker Polar Sea approaches iceberg B15A in the Ross Sea to deploy a field party from the University of Chicago.

Glaciological research at the University of Chicago is focused on the broad array of mechanical and thermodynamic processes that influence the large-scale patterns of ice sheet flow and evolution in response to changing climate. Many of the problems that we work on are multidisciplinary in nature involving a combination of theoretical techniques, numerical modeling, remote sensing, and field observation in Antarctica and Greenland.

Current projects include:

Surface melting and melt pond formation

Ice-shelf disintegration and ice/wave interaction

Recent video presentations:

• Doug's AGU ice shelf collapse presentation

Recent projects:

Iceberg drift

Iceberg calving

Ice-sheet and ice shelf modeling

Glacial seismology

Ice-sheet, ice-shelf and polar-ocean climate prediction

Sea-level rise over the next century
