An Introduction to GEOTRACES
Date: 04/30/15 7:00 PM Eastern - 04/30/15 8:00 PM Eastern
Location: Online

In the opening to the GEOTRACES webinar series, Dr. Ben Twining and Dr. Phoebe Lam will invite you in to the world of trace metals and provide a broad look at how these elements are used to understand the ocean's past, present and future.

GEOTRACES Webinar Series
Seawater's composition reflects our planet’s history, along with traces of human impacts. The chemistry of trace 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 mercury) across the world’s oceans.

This four-part GEOTRACES webinar series will focus on several trace elements and what they can tell us about 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 researching these rare and vital “clues” from the ocean.

Ben Twining 

Ben Twining is the Director of Research and Education at Bigelow Laboratory for Ocean Sciences in East Boothbay, Maine. He received a Ph.D. in Coastal Oceanography from Stony Brook University and an A.B. in Environmental Science and Public Policy from Harvard University. His research interests focus on the interactions between metals and planktonic organisms in marine and aquatic environments.

Phoebe Lam 

Phoebe Lam is an Assistant Professor in the PBSci-Ocean Sciences Department, Institute of Marine Sciences at the University of California, Santa Cruz. She received her Ph.D. in Earth and Planetary Science from UC Berkeley and an M.A. in Geosciences from Princeton University. Her research interests include in the role that marine particles play in the biogeochemical cycling of major and minor elements in the ocean such as carbon, iron, and other trace elements.
