    Ocean Carbon and Biogeochemistry Workshop 2012
    (OCB Project Office, 2012-07)
    Multiple stressors in marine ecosystems: Marine ecosystems are facing multiple anthropogenic stressors, and although we are learning much about how individual stressors may impact ecosystems, we know little about synergistic effects. Ocean biogeochemistry from satellite data: Satellite ocean color data represent a critical observational resource in support of OCB research. Planning for the next NASA ocean color research mission PACE (Pre-Aerosol, Clouds, and ocean Ecosystem, http://decadal.gsfc.nasa.gov/PACE.html) is currently underway, with an anticipated 2019 launch. Land-ocean transport and linkages with global change: Approximately 87% of Earth’s land surface is connected to the ocean by rivers. Over the past 50 years, increases in the human population have had severe global impacts on large-river systems through enhanced fertilizer usage, damming, deforestation, and many other land-use changes. Integrating measurements across multiple time and space scales: Long-term biogeochemical studies conducted over decades at single locations (i.e. Ocean station Papa, HOT, BATS, CARIACO) or across large regional areas (i.e. CalCOFI / CCE-LTER) allow researchers to integrate and synthesize data over multiple temporal and spatial scales. New observations from an Arctic Ocean in rapid transition: The Arctic is undergoing rapid changes in response to warming, accelerated melting of large ice sheets, and reductions in seasonal sea ice cover.

    (OCB Project Office, 2011-07)
    Trends, Thresholds, and Tipping Points in Marine Ecosystems: The oceans represent one of the largest and most active carbon reservoirs on the planet. With atmospheric CO2 levels on the rise, there is serious concern about the physical, chemical, and biological impacts of continued oceanic uptake of anthropogenic CO2. When combined with other environmental stressors such as greenhouse warming, decreasing oxygen levels, pollution, etc., this carbon reservoir is particularly susceptible to rapid, nonlinear shifts in biogeochemistry, physical circulation, and biology that could fundamentally change the global carbon cycle as we know it. OCB and U.S. CLIVAR: Given the overlapping scientific and observational interests of the two programs, the goals are to explore science issues of common interest and identify initial high-priority research topics that may lead to joint activities (e.g., the formation of focused working groups) between U.S. CLIVAR and OCB researchers over the next decade. Toward the Implementation of a Global Autonomous Biogeochemical Observing System: The challenge of understanding the ocean’s role in the global carbon cycle and its response to a changing environment requires an expanded scale of observation in both space and time.

    Ocean Carbon and Biogeochemistry Workshop 2010
    (OCB Project Office, 2010-07)
    This year’s OCB summer workshop highlighted three interdisciplinary science themes: Arctic, low oxygen regions, and benthic-pelagic coupling. Within these themes, we were especially keen to address nitrogen cycling, ecological tipping points, and strengthened connections between experimentalists and modelers. Arctic: The Arctic is undergoing rapid changes in response to warming, accelerated melting of large ice sheets, and reductions in seasonal sea ice cover. Low Oxygen Regions: Many models are predicting a significant expansion of oxygen minimum zones under the IPCC “business-as-usual” scenario for anthropogenic CO2 emissions, which will affect marine productivity, carbon and nutrient cycling, and food webs. Benthic-Pelagic Coupling: Benthic and pelagic ecosystems are intimately linked by way of biogeochemical cycling and transformation. Benthic-pelagic coupling along continental shelves represents a significant unknown in coastal carbon budgets, and the physical, chemical, and biological processes driving organic carbon export and burial in the open ocean remain poorly characterized.

    Ocean Carbon and Biogeochemistry Workshop 2009
    (OCB Project Office, 2009-07)
    This year's workshop included the following interdisciplinary sessions: The Next U.S. Carbon Cycle Science Plan: Although the research priorities identified in the 1999 U.S. Carbon Cycle Science Plan still remain important, a new set of challenges must be addressed in the coming decade, including the effects of human activities on carbon cycling, the sensitivity of ecosystems to changes in carbon cycling and climate, and the efficacy and environmental consequences of carbon management practices. Observing Systems and Time-Series: Ship- and satellite-based ocean observations and time-series form a critical foundation for OCB research. Community planning discussions and input to large-scale national and international planning efforts are essential to ensuring long-term availability of biological, chemical, and ecological data sets that support this research. The Future of OCB Research in the Southern Ocean: The Southern Ocean represents a key system in the global ocean with a critical role in climate and biogeochemical cycles. There is still a troubling level of uncertainty surrounding the impacts of climate change on circulation, CO2 fluxes, productivity, and ecosystem structure in the Southern Ocean. Ocean Acidification: Frontiers in Understanding Physiological and Ecological Responses: Ocean acidification is a high-priority OCB research topic. Recent developments such as the passage of the Federal Ocean Acidification Research And Monitoring Act and the forthcoming NRC report on ocean acidification make this a critical time for soliciting community feedback on new research directions and activities. Implementing Research at the Intersection of Ocean Chemistry and Biology: Two important efforts that advocate for a more integrated observational approach to better address complex feedbacks between ocean chemistry (e.g., micronutrients) and marine ecosystems are currently underway within the OCB-affiliated programs GEOTRACES and SOLAS. NACP/OCB Coastal Interim Synthesis Activities: The objective of the coastal synthesis activities is to stimulate the synthesis and publication of recent observational and modeling results on carbon cycle fluxes and processes along the North American continental margin.

    Ocean Carbon and Biogeochemistry Workshop 2008
    (OCB Project Office, 2008-07)
    The focus of this year’s workshop was on the following interdisciplinary themes: Climate sensitivity of ecosystem structure and associated impacts on biogeochemical cycles Implications of climate variability and climate change for ocean biogeochemistry and benthic and pelagic ecosystems covering all trophic levels. Carbon uptake and storage Recent observational and modeling findings quantifying the magnitude and trends in ocean carbon fluxes and carbon storage. Temporal trends in ecosystem variability Application of ocean time-series data to characterize ecosystem response to varying climatic and biogeochemical boundary conditions. The session will include both modern and paleo-time-series in order to place the trends over the past century and future trends in a broader temporal context.

    Ocean Carbon and Biogeochemistry Workshop 2007
    (OCB Project Office, 2007-07)
    The summer 2007 OCB Science Workshop seeks to recognize new research opportunities at the interface between traditional disciplines. Participants are encouraged to "think outside the box" of their own immediate research communities and communicate with scientists in other disciplines. Three primary interdisciplinary themes have been identified for this workshop, bearing in mind that subsequent workshops will address additional themes - The interplay between biotic structure and biogeochemical cycles; Changing Ocean Biogeochemistry: the Prediction Challenge; Cross-boundary fluxes in the coastal ocean.
