Research Themes

  • Climate Research and Impacts – Data collection, analysis and modeling of earth climate, with a particular emphasis on tropical oceans and air-sea interaction, and the impacts of climate variability and change. Proposed projects include expansion of the tropical buoy network and climate network buoys, analysis of those data, regional modeling and analysis of Pacific Northwest climate, and studies that elucidate directions for the proposed NOAA climate service.
  • Polar Research – Arctic climate, past and future, sea ice changes, arctic buoy program, and marine ecosystem studies. Proposed projects include further climate simulations, ice thickness data retrieval and management, expanded buoy program, and detailed examination of arctic ecosystems.
  • Aerosol Research – Measurements of aerosol properties, continued instrument development, black carbon impact on snow, and synthesis of existing data. Proposed projects include continuation of shipboard aerosol measurement, data analysis and modeling of black carbon in snow, transport studies, and geo-engineering research.
  • Environmental Chemistry – Ocean uptake of anthropogenic CO2, ocean ventilation timescales and decadal variability, and biological carbon cycling. Proposed projects include continued monitoring of ocean carbon levels and concentrations of other tracers of anthropogenic activity such as CFCs, development of new measurement and analytic techniques, modeling of multiple tracers to understand biological activity, and determination of basin-wide net C export rates.
  • Ocean Acidification – Monitoring regional and global ocean acidification both, developing a global ocean monitoring network, and understanding acidification impacts. Proposed projects include continuation of data collection on cruises, deployment of additional moorings, development of new instrumentation, laboratory experiments on the effects of acidification on marine organisms, participation in a Puget Sound mesocosm facility for studying the effects of acidification on marine ecosystems, and forecasting ocean acidification rates.
  • Seafloor Processes – Locating, characterizing and quantifying hydrothermal venting; using shallow volcanoes to study the impacts of local ocean acidification and enrichment by iron; and developing innovative measurement approaches. Proposed projects include continued exploration of the ocean bottom and hydrothermal activity, expansion of the monitoring of iron fertilization rates and diagnosis of its impacts, and further instrument and sampling technology development including use of cabled seafloor observatories.
  • Marine Ecosystems – The response of Pacific Northwest salmon to climate variability and change and regional ocean modeling of physical and biological parameters in the Bering Sea and Gulf of Alaska. Proposed projects include analysis of data and development of models to study fish population with a specific focus on multistock interactions, coupling of the results of regional physical models with ecosystem models, and development and evaluation of fish management tools.
  • Protection and Restoration of Marine Resources -Climate impacts on harmful algal blooms in Puget Sound, studies of Puget Sound food webs, and studies of the impact of climate change on the Puget Sound basin. Proposed projects include determining the factors that control algal blooms and assessing potential impacts of anthropogenic activity on their frequency and duration, develop a model of the Puget Sound food web that can be used to monitor health of the Sound and long term impacts of development activity, and assess the potential impact of climate change on the Sound either directly or through changes in stream runoff timing and amount.
  • Tsunami Observations and Modeling – Tsunami forecasting, hazard assessment and inundation monitoring, and education and outreach. Proposed projects include completion of
    the tsunami forecasting database and model, further development of DART buoys, expanded partnerships with Washington and Oregon to investigate tsunami impacts such as coastal inundation, and continue and expand tsunami awareness education and training courses.
  • Ocean and Coastal Observations – Acquisition and analysis of oceanographic observations from the Global Tropical Moored Buoy Array, deployment of buoys in the Arctic and other climatically important regions, development of new instruments and ocean deployment strategies for them, and data management and software development. Proposed projects are largely covered in other sections; they include additional buoy deployments, new sensors for biological, chemical, and physical ocean properties, aerosol measurements and instrument development, and development of data analysis and visualization software.
