Nutrients in the Open OceanPresented by Claire Parker, Dr. Kristen Buck, and Dr. Kathy Barbeau - Tuesday, May 5, 2015
This webinar brought us into the world of phytoplankton to shed light on what these tiny creatures can tell us about some big-picture questions about carbon.
Nutrients are vital to productivity in the oceans, but can be hard to come by, creating an environment poised to "bloom" if the right ingredients are available. This webinar followed the path of nutrients critical to phytoplankton growth - and explored the question of how that relationship may (or may not) hold a solution to combat climate change, including the question of whether artificially “fertilizing” the ocean with iron is a viable option.
You can watch the archived video of the webinar below. Below the video are the concept maps that were presented, so that you can follow along with the video.

Claire’s concept map gives an overview of how nutrients enter the open ocean, how they are transported, and the patterns that can be seen across the globe and in the water column.
Kristen’s concept map addresses how the availability of micronutrients can affect the growth of a phytoplankton community, which in turn has effects on the food web and the carbon cycle.
Kathy’s concept map presents the science of iron fertilization experiments, which aim to create algal blooms in iron-limited areas to increase the amount of carbon reaching the deep ocean. The possible outcomes (both positive and negative) are included on the map.
Kathy Barbeau is a Professor in the Geosciences Research Division, Scripps Institution of Oceanography. She received her Ph.D. from MIT and a B.S. from Southampton College of Long Island University. Her research interests include the biogeochemical cycling of trace metals in marine systems; the biological transformations of trace metal speciation; photochemical redox cycling of trace metals; and metals as limiting or co-limiting micronutrients in marine planktonic systems.
Kristen Buck is an Assistant Professor at the University of South Florida. She received her Ph.D. in Ocean Sciences from the University of California Santa Cruz and a B.S. in Chemistry from Pacific Lutheran University. Research in the Buck lab is focused on the biogeochemical cycling of trace metals in marine ecosystems, with particular emphasis on the role of metal-binding ligands in the cycling of bioactive trace elements like iron and copper.
Claire Parker is a Ph.D. student in the Ocean Sciences Department, University of California. She received a B.S. in Chemistry from Bates College.
