We are on the R/V Falkor until the new year, studying the sea surface microlayer.

See you at Ocean Sciences Meeting 2020! Chris, Nathan, Suki, Una, and Carson are all presenting.

August 2019

Chris, Nathan, and Sophia have a new paper published in Geophysical Research Letters on the response of the thermal skin layer to wind gusts: The Impact of Wind Gusts on the Ocean Thermal Skin Layer

The Sea Surface Microlayer Universe
A multi-disciplinary and multi-institutional effort to increase our understanding of the significance and role of the air-sea interface (sea surface microlayer, SML) as the boundary layer controlling atmosphere-ocean interactions. The first phase of this project took place in 2016 on the R/V Falkor in the Timor Sea. The second phase is ongoing.

Investigating the Turbulent Kinetic Energy Budget Across the Air-Sea Interface
We have mounted a suite of instruments and imaging systems on the Air-Sea Interaction Tower (ASIT), a platform 7 kilometers offshore of Martha's Vineyard. Data from these devices is continuously transmitted across Martha's Vineyard Sound, allowing for around-the-clock monitoring of wind, wave, and current conditions. This effort embodies the Lamont-Doherty Earth Observatory's Real-Time Earth strategic initiative.

The Terra Nova Bay polynya
In 2017 aboard the R/V Araon, we deployed a mooring equipped with instruments to measure temperature, salinity, wave characteristics, ice thickness, and vertical current velocities in Terra Nova Bay, Ross Sea in order to understand the formation and vertical mixing of High Salinity Shelf Water (HSSW), an important constituent of the Antarctic Bottom Water that drives global ocean circulation.
