Nutrients in the Open Ocean
Date: 05/05/15 2:00 PM Eastern - 05/05/15 3:00 PM Eastern
Location: Online

Ever wonder how organisms get access to nutrients in the middle of the vast ocean? This webinar will follow the path of nutrients critical to phytoplankton growth - and explore the question of how that relationship may (or may not) hold a solution to combat climate change.

GEOTRACES Webinar Series
From the Earth’s crust, to beyond the edges of the continental shelf, to the middle of the open ocean, there is more to study in the ocean than just the life it contains. The chemistry of trace elements - elements found in such small concentrations that they can be difficult to detect - can be studied to uncover the past, present and the future of the ocean and life within it.

Using rigorous methods to ensure measurements are both accurate and consistently collected, the GEOTRACES program has mapped the large-scale distribution of trace elements (such as iron, lead, zinc, and cobalt) across the world’s oceans.

This four part GEOTRACES webinar series will focus on several trace elements and what they can tell us about ocean life, biogeochemical processes, the carbon cycle, and climate. Nine scientists, each studying a unique facet of the ocean’s chemistry, will share their work and the importance of understanding these rare and vital “clues” from the ocean.

Kathy Barbeau 

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 

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 

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.
