For the past six Antarctic field seasons that usually run from November through February, Ted Scambos and colleagues have been posting updates about their expedition to the Larsen Ice Shelf region, as part of the National Science Foundation (NSF)-funded Larsen Ice Shelf System Antractica (LARISSA) project. LARISSA’s goal is to understand the causes and consequences of a rapidly changing part of Antarctica, from climate to ice to ocean and the seabed below, and then to the ecosystem evolving and adapting to the change.
This season, we return to the Antarctic Peninsula where a large plate of ice is on the brink of collapse, and test a new instrument on a frozen Colorado lake. The instrument (an ‘AMIGOS-II’, upgraded from the devices already operating in Antarctica) is designed to make combined measurements of weather, ice conditions, and ocean currents and temperature from atop an ice shelf or sea ice. The Antarctic field work is first, and then we’ll shift over to track the instrument expedition in February.
