"Mercury Cycling in Warming Oceans"

Mercury is a naturally occurring element that has been mined and released by humans for over 3,000 years. Inorganic mercury is released by human activities and makes up most of the mercury reservoir in the environment. However, only the organic/methylated forms of mercury (methylmercury) accumulate in food webs and can lead to neurological and cardiovascular impairments in humans. Understanding the microbial transformations and geochemical conditions conducive to the formation of organic mercury has been the focus of many years of research due to global impacts on the health of fish-consuming wildlife and human populations. Most of the global methylmercury exposure for human populations is from marine ecosystems due to bioaccumulation in predatory fish at levels that are a million times, or more, higher than seawater. This presentation will provide an overview of recent advances in the understanding of organic mercury formation, uptake by phytoplankton, and biomagnification in marine food webs. My approach combines new field data collection, experimental measurements, isotopic tools, and numerical modeling. I will also discuss how changes in the biogeochemistry of marine ecosystems (temperature, stratification, dissolved organic carbon, trophic structure) are affecting the mercury cycle.
