The Zappa Lab is tracking High-Salinity Shelf Water formation in Terra Nova Bay, Ross Sea, and its spread into the deep ocean, where it eventually becomes AABW.

They studied Antarctic Bottom Water (AABW) in the Austral summer of 2024. As part of the expedition, the RV Araon resupplied and relieved personnel at Jang Bogo Station, seen in the distance of this picture from the stern of the RV Araon. Stay tuned for their research in the coming weeks!

AABW forms from cold, dense shelf waters in Antarctica, it is influenced by sea ice, winds, and glacial interactions. Zappa Lab is tracking High-Salinity Shelf Water formation in Terra Nova Bay, Ross Sea, and its spread into the deep ocean, where it eventually becomes AABW.

The study areas range from laboratory wind-wave tanks, to rivers and estuaries, to shelf seas and polynyas, to the open ocean, from the poles to the equator.

The group develops and deploys instruments including infrared, multispectral, and polarimetric cameras, as well as turbulence sensors, on fixed and mobile platforms such as ships, ocean towers, moorings, drifting buoys, and uncrewed airborne systems (UAS).

OASIS conducts observational research focused on the oceanic and atmospheric boundary layers. This includes ocean waves and wave breaking, air-sea CO2 exchange, near-surface ocean and atmospheric turbulence, and boundary-layer processes affecting heat, mass, and momentum transport.
