We thank the Intergovernmental Oceanographic Commission, the United States National Science Foundation (OCE-9523159 for ship time), the Habitat Chemistry Section of the Marine Environmental Science Division of the Department of Fisheries and Oceans, Bedford Institute of Oceanography, and the captain and crew of the research vessel Knorr for their support of the 1996 Baseline Expedition. We thank the officers and crew of the research vessels Henlopen and Weatherbird II for their help in these studies. We thank Neil Blough for allowing us to participate in the Henlopen cruises, and Tom Church and Maureen Conte for allowing us to join their cruises to the BATS site. The laboratory oxidation studies were done in the Chemistry Department at the University of Maryland, College Park, in Neil Blough's laboratory. We acknowledge all the members of our research group who have helped in various ways. The help of Brenda Yates for manuscript preparation is appreciated. We thank the National Science Foundation, Chemical Oceanography for funding this research (Grants # OCE-9633207 and 9530526). This is Contribution 3426 of the University of Maryland Center for Environmental Science.

N2 - To understand further the cycling of mercury at the earth's surface we discuss the results of recent measurements of Hg concentration and speciation in the upper ocean and marine boundary layer of the Atlantic Ocean. In water, dissolved gaseous Hg (DGHg) and total Hg measurements are reported; for the atmosphere, total gaseous Hg, reactive gaseous Hg (RGHg) and particulate Hg measurements were made. These measurements allow estimation of gas evasion to the atmosphere and deposition to the ocean. In conjunction with the field collections, incubation experiments both on board ship and in the laboratory have examined further the processes controlling the oxidation and reduction of Hg species in water. Our results suggest that dry deposition of RGHg could be significant.
