Background

My name is Nathan Laxague. I study physical processes at the air-sea interface as a postdoctoral research scientist at Columbia University’s Lamont-Doherty Earth Observatory. 
I am an observationalist; I make field and laboratory measurements and use them to explore the small-scale fluid mechanical interactions between the Earth’s atmosphere and oceans. My particular area of interest is in short-scale wind waves and their mediation of air-sea momentum, heat, and mass flux. 
Presently, I'm part of an exciting project (called Ikaaġvik Sikukun) which approaches the topic of atmosphere-ice-ocean interaction in the Arctic by bridging scientific inquiry with traditional knowledge.
