OM42A:
Ensemble Modeling Approaches in Physical and Biogeochemical Oceanography I


Session ID#: 37798

Session Description:
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.
