The National Science Foundation (NSF) awarded a $397,400 Project Grant under the Geosciences program (CFDA 47.050) to the University of Southern California (USC) to conduct collaborative research on the impact of ocean warming on bioactive trace metal requirements and use efficiencies of marine nitrifying microorganisms. This 3-year project aims to provide a deeper understanding of how major biogeochemical cycles in the ocean will respond to climate change. The research involves laboratory studies and field experiments to investigate thermal effects on iron and copper requirements of marine ammonia-oxidizing archaea and bacteria, as well as nitrite-oxidizing bacteria. The project will also examine the underlying molecular and biochemical mechanisms that enable these thermally-driven adaptive responses, and study system-level feedbacks between global change, trace metal biogeochemistry, and marine nitrifier communities. The grant supports the training of one postdoctoral researcher, three graduate students, and provides research opportunities for undergraduate students through various educational and outreach programs. All data generated from this project will be made freely available through the Biological and Chemical Oceanographic Data Management Office.
