ROSETTA's has a third field seaons scheduled in Antarctica! The team has completed two seasons November 2015 and 2016 and will return to complete the shelf mapping late October 2017. Follow our progress! Stay tuned!

Airborne Surveys - The primary fieldwork focuses on completing a survey, flying back and forth over the iceshelf, building a grid of. We will collect a suite of measurements including ice surface elevation using lidar, ice thickness using radar, the shape and materials of the ocean floor lying under the ice shelf using gravity and magnetics. Season one in 2015 flights were planned at 20 km grid spacing to put together the framework for the 2016 season. The density of the grid will double with the 2016 flights which are designed to be flown at 10 km spacing providig a much more complete picture of the ice shelf itself.
Ocean Measurements - To completement the airborne flights over ice we use Alamo drifters in the ocean. The drifters will collect data on ocean circulation along the front of the ice shelf where the ocean interacts with the ice shelf edge, and where it circulates in and under the ice. Matching this circulation data with the map we are creating for the ocean bed shape beneath the ice will improve our models of how warming water may lead to additional melting of the ice shelf.
