Alexander Andriatis
I'm a postdoctoral researcher in the Environmental Dynamics Laboratory at MIT, where I study ocean turbulence and particle transport. My current work supports understanding the efficacy of marine carbon dioxide removal and the environmental impacts of deep-sea mining. My research spans observational field campaigns using novel instruments, lab studies, and numerical modeling.
I am also a passionate decarbonization advocate and enjoy thinking about solutions for the clean energy transition.

Langmuir Circulations
Langmuir turbulence is a leading-order driver of mixing in the ocean surface boundary layer. We observe the onset and evolution of Langmuir circulations using novel observational techniques: airborne infrared imaging of the sea surface from a research aircraft, co-located with thermistor chains on wave gliders and drifting instruments below the surface. In comparing their structure to high-resolution numerical models, we identify strategies for improving the modeling of turbulent processes. Better parametrizations of Langmuir turbulence can serve to increase the accuracy of large ocean and climate models.
