This lab, currently under the guidance of Dr. Kenneth Coale, is one of the few labs in the world that can accurately collect and measure the low levels of trace metals in the ocean. Trace element distributions have been measured all over the world. They have participated in large, long term studies such as VERTEX and JGOFS which examine the processes that determine how elements are cycled throughout the oceans. They played a large and notable role in the IronEX studies, with cruises in the Southern Ocean around Antarctica determining iron and and nutrient distributions and conducting a Southern Ocean iron fertilization experiment. This year the lab published some of their recent collaborative work on the sources of mercury in marine fog along the California coast.
