Dust, Iron, and Nitrogen Fixers in the South Pacific

Dust, Iron, and Nitrogen Fixers in the South Pacific

The South Pacific Gyre is an oceanographic desert. Inward-spiraling currents push surface waters downward, prevent nutrient-rich waters from reaching the sunlit oceans, and inhibit plankton growth. It’s also about as far from the continents as you can get. So, atmospheric dust inputs are extremely low – and as a result, so are the inputs of micronutrients like iron, which are critical for the few biota that are around to conduct biochemical processes like nitrogen fixation. In 2015-2016, I sailed on…

Heading west!

On October 7th I defended my Ph.D. at Lamont-Doherty. If you want to devote an hour to learning about the marine chemistry of thorium and protactinium from me, you can watch a video recording of my defense talk, courtesy of Phil Fitzpatrick and the excellent LDEO IT team. If you want to devote more than an hour to learning about the marine chemistry of thorium and protactinium from me, you can read my thesis, “Biogeochemical Studies of the South Pacific…
