Co-sponsored by ASLO, AGU, and TOS, the Ocean Sciences Meeting 2018 will be held between February 11 and 16, 2018 at the Oregon Convention Center in Portland. Topics of focus at the Meeting will span a diverse array of marine science topics and issues.
Nereus Program Principal Investigator Ryan Rykaczewski (University of South Carolina) will be hosting a session (session ID #: 28650) at the Meeting titled ‘Closing the gap between wind stress and ecosystem productivity in eastern boundary upwelling regions.’
Eastern boundary upwelling ecosystems contain the most productive fisheries in the world. This immense fish production results from upwelled nutrients that stimulate high primary and secondary production. However, the relationships between atmospheric forcing and the ecological productivity of these ecosystems are not straightforward. Variability in nutrient stoichiometry, oxygen concentrations, nutricline depth, seasonal timing of upwelling, mesoscale and submesoscale variability, onshore geostrophic flow, and subduction of underutilized nutrients below the adjacent oligotrophic water masses are all examples of processes that can obscure the relationships between the intensity of upwelling-favorable wind stress and ecosystem productivity. In this session, we welcome contributions that investigate processes that may be crucial for resolving the relationships between atmospheric forcing and primary and secondary production. The objective of the session is to improve the community’s understanding of the processes and resolutions required (in both models and observations) to accurately describe the impacts of physical and biogeochemical drivers on fish and other higher-trophic-level populations of interest. Such understanding will allow better interpretation of non-stationary empirical relationships between physical conditions and ecosystem state, and is necessary to properly project and interpret ecological impacts of climate variability and change.
Nereus Principal Investigator Thomas Froelicher (Swiss Federal Institute of Technology Zurich) will be co-convening a session (session ID #: 28471) at the event on ‘Ensemble Modeling Approaches in Physical and Biogeochemical Oceanography.’
Ensemble modeling methods have been applied to a wide range of oceanographic and climate questions since their original application in numerical weather preduction several decades ago. Such applications currenty encompass not only climate projections (pertaining to detection and time of emergence) and predictability/prediction studies, but also forecast modeling (operational oceanography) and data assimilation. Additionally, ensemble methods are applied to physical state variables, ocean biogeochemistry, and potential ocean ecosystem stressors. As such, the range of applications informs and facilitates collaborative efforts in both the interpretation of an assimilation of observational records.
This session welcomes studies that employ ensemble methods in a wide range of applications relevant to physical and biogeochemical oceanography and the role of the ocean in the climate system. Abstracts are particularly welcomed that focus on the interplay between ocean physical and biogeochemical processes, proceses in high-latitude environments, and studies of marine ecosystems under a changing climate.
