Dr. Cutter leads latest US GEOTRACES expedition in the Pacific Ocean - from Alaska to Tahiti


Dr. Greg Cutter is chief scientist for an oceanographic cruise that is a key transect for the international GEOTRACES program to examine the biogeochemical cycling of trace elements and isotopes in the world's oceans. The expedition is using R/V Roger Revelle and leaves Seattle on 18 September, transits up to just west of Kodiak Island, Alaska, then proceeds due south along 152 W longitude to Tahiti, arriving on 24 November. Dr. Cutter and his colleagues will sample at 37 stations along the way.

The cruise has a website, which will be updated daily, so you can follow the adventure and science. With Dr. Cutter are current OES graduate students, Nicole Buckley and Sveinn Einarsson. Sveinn is in charge of all the biological measurements. Nicole is keeping a blog, , that will describe her research as it progresses and detail her experiences on this, her first cruise. Former OES student, Kyle McQuiggan, is also on-board to operate the sampling systems. Cutter, and Lab Manager Lisa Oswald will perform shipboard determinations of zinc to monitor potential contamination with the sampling system and ultra-low nutrient concentrations in surface waters. Please visit the cruise's website, where you can interact with the scientists via the website blog.
