crew_harden_en_119330I am a high latitude oceanographer and meteorologist working as a postdoc at the Woods Hole Oceanographic Institution.

I also make radio and video about ocean science and other things I find intriguing.


My science research centers on ocean currents in the North Atlantic, intense winds around the coast of Greenland, and how these interact to regulate our planet’s climate.  [read more]

A Scientist Unlocks One of the Mysteries of Arctic ice melt

On a research voyage through the Arctic ice cap, a scientist has a eureka moment, one that he hopes will help solve some of the riddles about Arctic ice melt — and what’s ahead for the rest of the planet as the climate warms. [Story on PRI’s The World]

We’ll Get There Eventually

97 feet above sea level, in a small room on top of a pole, Tahnee Zacanno looks out over the Arctic sea ice.
