The Coupled North Atlantic-Arctic System: Processes and Dynamics

The North Atlantic-Arctic circulation and its responses and links to climate variability are the focus of international and U.S. research programs. Recently, this focus has expanded to include biogeochemical and ecosystem processes and their sensitivities and responses to climate and circulation variability. The interdisciplinary research needed to investigate the North Atlantic and Arctic circulation, climate, and ecosystem function and associated variability requires collaborative international research programs. An international planning workshop, co-sponsored by NSF and the European Union (EU), was held in April 2014 with the goal of developing a core science vision and detailed science plan to guide the next phase of research focused on the coupled North Atlantic-Arctic system. This session will report the results of the planning workshop and provide plenary presentations that outline the basis for the development of overarching science questions and research directions for a research program focused on the North Atlantic-Arctic system. Confirmed speakers for this session so far include Dennis McGillicuddy (WHOI), Andrey Proshutinsky (WHOI), Paty Matrai (Bigelow), Tatiana Rynearson (URI), Jim Overland (NOAA/PMEL), Y-O Kwon (WHOI), Andy Pershing (GMRI), and Jeremy Mathis (NOAA/PMEL).

The Biological Pump: Transport Mechanisms and Mesopelagic Processes

The biological pump represents a critical component of the ocean carbon cycle. In the past 1-2 decades, advances in ocean observing (e.g., autonomous platforms) and analytical (e.g., -omics techniques) capabilities have helped to better quantify key vertical fluxes and describe with unprecedented detail the roles of biota associated with these fluxes. A community effort focused on the biological pump called EXPORTS may potentially be funded by NASA, so this science session is a timely review of what we’ve learned since JGOFS and where we are headed in the future. This session will include a set of talks focused on transport mechanisms, including passive transport, vertical migration, and physical delivery of DOM, and how our understanding has advanced since JGOFS. A second set of talks will focus on biological and biogeochemical processes in the mesopelagic zone. Confirmed speakers for this session so far include Debbie Steinberg (VIMS), Adrian Burd (UGA), Carol Arnosti (UNC), Craig Carlson (UCSB), Ken Buesseler (WHOI), Ben Van Mooy (WHOI), Stephanie Wilson (Bangor Univ.), Christina De La Rocha (Univ. Brest), Alyson Santoro (UMCES), Santiago Hernández-León (Univ. Las Palmas), Henry Bittig (GEOMAR), and Sarah Giering (NOC).

Advances in our Understanding of the Role of Sea Ice in the Global Carbon Cycle

The polar oceans are undergoing rapid changes, with globally significant implications. Sea ice plays a fundamental role in the transport and storage of carbon and biogenic gases in the polar oceans. This session will focus on our current understanding of the role of sea ice in the global carbon cycle. Confirmed speakers for this session so far include Manfredi Manizza (SIO), Brice Loose (URI), Ted Maksym (WHOI), Nick Bates (BIOS), Clara Deal (UAF), and Bruno Delille (FRS-FNRS).
