Description

This project operates, maintains, upgrades, calibrates, and services the joint U.S. Comprehensive Nuclear Test Ban Treaty (CTBT) station at Windless Bight. Windless Bight's location on the Ross Ice Shelf is unique for its very-low wind levels, which makes infrasound detection possible. Infrasound can detect volcanic eruptions, winds over distant mountain ranges, large storms at sea, auroral and meteor events, earthquakes, avalanches, and human-caused events such as very large explosions.


Field Season Overview

The field team, equipped with standard remote field equipment (including snowmobiles, PistenBully, and Mattrack vehicles) will stay in a self-supporting field camp at Windless Bight for four weeks. The camp will consist of two Polarhavens and six individual mountain tents. The team will typically stay at the field site but will intermittently return one or two team members to McMurdo Station for supplies and overnight stays. The USAP also provides year-round on-site support from a support contractor research associate (RA), who occasionally visits the site during winter months for maintenance and troubleshooting.
