Subcommittee Contact — richard.valigura@noaa.gov The Chesapeake Bay Program (CBP) is a multi-agency program of targeted scientific research and integrated assessment, which has been instrumental in alerting policy makers to the need to couple air and water issues in their decision-making processes. Characterizing the East and Gulf Coast Atmospheric Resource Contact — bruce.hicks@noaa.gov It is clear that emissions from the “airshed” that serves as a regional origin of air pollutants affecting the Chesapeake Bay also influence other coastal ecosystems. east coast estuarine and coastal ecosystems would benefit as well. Research Grade Monitoring of Deposition in the Coastal Zone Contact — richard.artz@noaa.gov The atmospheric deposition that affects east coast ecosystems

is very poorly measured. For dry deposition, there are very few data points. The NOAA Atmospheric Integrated Research Monitoring Network (AIRMoN) has constituted a framework for exploring methods for quantifying the actual deposition loadings to the Chesapeake Bay watershed. ARL is currently operating several AIRMoN stations in the watershed — State College, PA, is a long-term site where both wet and dry deposition are being studied. Modeling Deposition to the Coastal Zone at Regional Scales Contact — rdennis@hpcc.epa.gov The Regional Acid Deposition Model (RADM) has been adopted as the modeling workhorse of the east coast estuarine regulatory community. The results indicate that grid sizes *2 km may be necessary to resolve the effects of the Bay on atmospheric dry deposition

(but not wet). Estimating Air-Water Exchange of Nitric Acid in Coastal Areas Contact — richard.valigura@noaa.gov A project was successfully undertaken which, i) developed and evaluated an iterative bulk exchange model to estimate air-water exchange of heat, water and momentum from buoy data, and ii) used the model outputs to estimate air-water transfer rates of nitric acid (HNO3). Natural emissions of Oxidant precursors: Validation of techniques and Assessment (NOVA) Contact — winston.luke@noaa.gov Historically, NOx emissions from soils have been estimated using chamber, or enclosure, techniques, whereby the measured rate of increase of [NO] within the chamber used to derive an estimate of the NO emission flux from the underlying soil surface. Mercury Deposition Contact —

meyers@atdd.noaa.gov ARL researchers at Oak Ridge (a collaboration between ATDD and Oak Ridge National Laboratory) have been working on techniques to measure the deposition of mercury directly. More recently, field studies have been conducted in southern Florida, where mercury originating from sugar farming practices is suspected to be affecting coastal ecosystem viability. Research Plans Linkages within NOAA The ARL coastal studies program is strongly linked with the NOAA Chesapeake Bay Office of the National Marine Fisheries Service. The work is also tied to the NOAA Coastal Ocean Program, and to coastal activities of the National Ocean Service. The Chesapeake Bay Air Subcommittee (led by ARL) serves as an interface with all federal agencies involved in related research (EPA,

DOD, DOE, DOI, DOA, NASA, Smithsonian) as well as with the air and water environmental components of each of the states in the Chesapeake Bay region (Delaware, New York, Pennsylvania, Maryland, Virginia, District of Columbia, West Virginia). Describing statutory authorities which help the NPS protect air resources. In 1983, barely a half dozen parks were using air quality information in interpretive/educational programs.
