Where is ocean acidification research going?

Professor Ken Caldeira is a climate scientist at the Carnegie Institution for Science, where his job is “to make important scientific discoveries.” He also serves as a Professor (by courtesy) in the Stanford University Department of Earth System Science.

Ken is a member of the committee producing the 2015 U.S. National Academy of Sciences report “Geoengineering Climate: Technical Evaluation and Discussion of Impacts”. He is also a contributing author to the Intergovernmental Panel on Climate Change (IPCC) AR5 report Climate Change 2013: The Physical Science Basis.

In 2010, Ken was a co-author of the 2010 US National Academy America’s Climate Choices report and was elected Fellow of the American Geophysical Union. He participated in the UK Royal Society geoengineering panel in 2009 and ocean acidification panel in 2005. Ken was coordinating lead author of the oceans chapter for the 2005 IPCC report on Carbon Capture and Storage.

Challenge of deciphering information fro the paleo record

Barbel Honisch is an Associate Professor in the Department of Earth and Environmental Sciences and at the Lamont-Doherty Earth Observatory of Columbia University in New York.

Originally trained as a biologist, Barbel developed an interest in paleoceanography, geochemistry and proxy validation, with special focus on reconstructing past marine carbonate chemistry from foraminifers. Her research includes laboratory culture studies with planktic foraminifers, sediment coretop validation studies and reconstructions of past climate change and ocean acidification.

Working with a number of graduate students and postdocs, Barbara’s current research projects include establishing the magnitude of sea-surface acidification during the Paleocene-Eocene Thermal Maximum, testing geochemical proxy relationships under variable paleo-seawater chemical compositions, reconstructing surface and deep ocean carbonate chemistry across the mid-Pleistocene transition, and reconstructing paleo-pH across the Middle Eocene Climatic Optimum.
