AB: In order to determine the spatial distribution and biological impacts of contaminant metals and nutrients associated with the Hudson River buoyant plume, the transport and transformations of mercury, other trace metals, and major nutrients are being measured as part of the LaGrangian Transport and Transformation Experiment (LaTTE). Beginning in the spring of 2004, a series of dye patch experiments will be carried out that will include continuous underway chemical and biological sampling within the well-sampled framework of an operational ocean observatory. During the first experiment in May 2004, surface water samples for dissolved and suspended particle concentrations of mercury, monomethylmercury, and bioactive and non-essential trace metals were collected using a trace metal clean, underway sampling system. A semi-continuous (5 min resolution) record of dissolved gaseous mercury (elemental mercury) in surface waters revealed diurnal patterns of mercury reduction and volatilization. The results of this project will improve predictions of contaminant movements and ecosystem impacts within the Middle Atlantic Bight.
