Description

The Ross Ocean and ice Shelf Environment, and Tectonic setting Through Aerogeophysical surveys and modeling (ROSETTA) project aims to advance understanding of the dynamics of the ice-shelf system. To accomplish this, ROSETTA researchers will collect new high-resolution data that will determine the thickness and structure of the Ross Ice Shelf (RIS) and characterize the bedrock and seabed bathymetry under the ice shelf. The ROSETTA surveys will acquire magnetic and gravity data for geologic interpretations, and radar, LiDAR, and imagery for mapping the RIS fine structure, including crevasses and channels, debris, and the distribution of marine ice and accumulation.


Field Season Overview

During this first of two proposed field seasons, the ROSETTA team will acquire aerogeophysical data using the IcePod sensor suite and two gravimeters installed in an LC-130 aircraft provided by the New York Air National Guard 109th Airlift Wing. Data collection will be generally along 10-km spaced east-west lines and 55-km spaced tie lines over the entire RIS.
