Abstract

Mercury is a fickle element, existing in the biosphere in three physical states and in many different chemical species. Its concentration in the biosphere has increased fivefold since the beginning of the Anthrocene age, primarily through the proliferation of coal-fired power plants and has had a negative impact on some ecosystem services. Researchers now recognize that the cycling of mercury is controlled by many different biotic and abiotic processes, some of which result in the production of the neurotoxin, methylmercury. This talk will review our work with mercury and highlight the discoveries that have led to a new paradigm of mercury transport from sea to land via marine advective fog. This transport impacts mercury concentrations in terrestrial biota. The results of our recent NSF study will be presented.

Biographic information

Kenneth Coale received his BS and PhD in biology from UC Santa Cruz and has pursued a career in oceanographic chemistry, developing automated and in situ methods for the determination of trace metals in sea water. When not teaching marine biogeochemistry as a CSUMB professor at MLML, he has been a visiting scientist in Juelich, Germany and at the Netherlands Institute Of Ocean Research, as well as Chief Scientist on all the US-led Iron Enrichment Experiments (Equatorial Pacific, Southern Ocean), and an Adjunct Professor at the University of Ghana. Dr. Coale is a Fellow of the California Academy of Sciences and of the American Association for the Advancement of Science, and has been a member of the ACS since 1988.
