Jarek Kwiecinski is an undergraduate student studying environmental engineering at the Massachusetts Institute of Technology (MIT). Before coming to MIT, he worked with researchers at the University of New Mexico to study microbial growth efficiencies and nutrient cycling in desert soils. He now works as an undergraduate researcher in MIT’s Earth, Atmospheric, and Planetary Sciences Department on ocean biogeochemistry projects focused on the Eastern Tropical North Pacific. On this cruise, Jarek will measure nutrient concentrations to determine rates of nitrogen and phosphorous cycling in a tropical Pacific oxygen deficient zone.
