Ocean Carbon Hot Spots Workshop
Biophysical drivers of carbon uptake in western boundary current regions
Western boundary current (WBC) regions display the largest magnitude air-to-sea carbon dioxide (CO2) fluxes of anywhere in the global ocean, exhibit large spring blooms and high eddy activity, and are hubs for the subduction of anthropogenic carbon-laden waters into the ocean interior during mode water formation. Yet the influence of biophysical interactions on air-sea CO2 exchange and carbon export has not been rigorously evaluated in most WBC regions.
The term Ocean Carbon Hot Spots refers to the WBC regions of the ocean, which exhibit large mean annual air-to-sea CO2 fluxes (blue regions in Figure 1a) and elevated surface eddy kinetic energy (blue regions in Figure 1b) – characteristics ideal for the study of biophysical interactions and carbon cycle processes.
The goal of the workshop is to develop an interdisciplinary research community that will facilitate a better understanding of carbon uptake and storage in WBC regions with an emphasis on the Kuroshio Extension. Furthermore, the workshop aims to develop a community of observationalists and modelers to collaborate on carbon cycle research near this region, increasing efforts to leverage observational capabilities to fill in modeling gaps and leverage modeling tools to inform observational strategies. The workshop will also identify critical observational needs that would improve model parameterizations of key biophysical processes that influence carbon uptake. This will guide future operational efforts to coordinate an international field program near the Kuroshio Extension, as well as recommendations for strategic long-term observing needs.
The workshop will bring together the physical, chemical, and biological oceanographic observing community with the climate modeling community. Meeting participation will be limited to ~60 attendees selected through an online application process.
The workshop will begin with a keynote address reviewing physical and biogeochemical processes in WBC regions. The remainder of the workshop will include four sessions distributed over two days with time devoted to discussion and synthesis after each session, which will help guide the workshop report and review paper. The organizing committee will invite speakers for select topics in addition to choosing speakers (particularly early career scientists and students) from the pool of applicants who indicate an interest in presenting when filling out the online application. Those who submit an abstract and are not slated to give a talk may be selected to present a poster. Due to time and space restrictions, the organizing committee will make decisions based on the total number of abstracts received.
Community building, expansion of cross-disciplinary vocabularies, and facilitation of new collaborations are all intended outcomes of the workshop. In addition, synthesis of modeling and observational perspectives will be collected to inform recommendations for OceanObs’19.
The organizing committee will synthesize the workshop presentations and discussion to generate a report, to be jointly published by US CLIVAR and OCB. A shorter workshop summary will be included in CLIVAR and OCB newsletters and websites.
