The Antarctic Automatic Weather Station (AWS) network has been making meteorological observations since the early 1980s. This continent-wide network is positioned to observe significant meteorological events and increase understanding of the Antarctic surface climate, helping researchers observe and learn about the Antarctic in a warming world. Numerous studies of surface climatology in regions around the continent, like the Ross Ice Shelf, have been possible because of the long duration of the AWS project and regular AWS maintenance. This AWS-based climatology also aids in other studies such as winter warming events.

Field Season Overview

Six team members will deploy for the second component of the O-283-M event. They will conduct field work in West Antarctica, the Ross Ice Shelf, and around the local McMurdo Station area. The team will visit and repair AWS stations that develop problems during the Austral winter, and as needed throughout the deployment. Specific location details include: (1) West Antarctic sites, based out of WAIS. Austin, Kathie, Bear Peninsula, Thurston Island, Evans Knoll, and Janet are scheduled for maintenance during the 2017-2018 season; (2) Ross Ice Shelf work, based out of McMurdo Station. The following AWS sites are scheduled for maintenance during the 2017-18 season: Gill, Sabrina, Lettau, and Alexander Tall Tower!; (3) Ross Island sites including Willie Field, Windless Bight, and Pegasus North can be visited using ground transportation. Helicopter support will be required to access Lorne, Linda, Marble Point, Minna Bluff, and Cape Bird sites. One McMurdo research associate (RA) provides support year-round.
