Investigating Iceberg Evolution During Drift and Break-Up: A Proxy for Climate-Related Changes in Antarctic Ice Shelves
Entry ID: scambos_0540915


Summary
Abstract: Drifting tabular icebergs in the Southern Ocean just east of the Antarctic Peninsula undergo a rapid "climate change" as they move into warmer air and ocean temperatures. Using a combination of satellite sensors and satellite-uplinked automated observing stations on two icebergs during 2006-2007, we examine these changes for clues to ice shelf and ice tongue break-up processes. Icebergs evolve ... View entire text

Description: Expedition Home page - After landing on the iceberg, the international team installed weather instruments, a video camera, and snow sensors on the iceberg's surface. These tools are now collecting data and sending it via satellite to researchers who will study how the iceberg changes as it drifts along its characteristic track northward, out of the Weddell Sea and into warmer climes.

Within a handful of years, the iceberg will drift away from Antarctica and into the South Atlantic, where air and ocean temperatures are much warmer. The new climate will induce rapid breakup, providing important information on the disintegration process.

See the Mission Log for day-to-day descriptions of the projects the team undertook during the expedition.
