Role of snow distribution processes in Antarctic sea ice mass balance

Program Manager:
Dr. Peter Milne


ASC POC/Implementer:
Cara Ferrier / Samina Ouda

Dr. Katherine Colby Leonard (Principal Investigator)

University of Colorado Boulder
Boulder, Colorado

Supporting Stations:  Special Project
Research Locations:  Weddel Sea

Project Description:
Snow depth and hence mass balance of sea ice is controlled by how blowing and drifting snow control the accumulation of snowfall on the ice and how the ice morphology control its distribution. Researchers will sail on two cruises and perform detailed measurements of drifting snow and snow distribution over sea ice.

Field Season Overview:
Two participants will join Alfred Wegener Institute expedition aboard the RV PolarStern from Cape Town, South Africa to Punta Arenas, Chile via the Weddell Sea. They will deploy nine drifting sea ice buoys that will transmit data by Iridium for the lifetime of the buoys, estimated to be 3-5 months.

Deploying Team Members:

  • Katherine Leonard (PI)
