The Global Nutrient Cycle: Past and Present

Current Project: DEVOCEAN – Impact of diatom evolution on the oceans

Motivated by a series of recent discoveries, DEVOCEAN will provide the first comprehensive evaluation of the emergence of diatoms and their impact on the global biogeochemical cycle of silica, carbon and other nutrients that regulate ocean productivity and ultimately climate. We propose that the proliferation of phytoplankton that occurred after the Permian-Triassic extinction, in particular…

About Me

Dr. Kristin Doering. Personal Profile I am an experienced marine biogeochemist and micropaleontologist having worked with Mg/Ca ratios on foraminifera, silicon isotope analysis of diatoms, radiolaria, and recently sponge spicules, as well as nitrogen isotope analyses of bulk sediments. My research interest is the reconstruction and interpretation of the past nutrient cycling in terms of…
