Project Proposal: Fate of Upwelled Waters in the Northern Arabian Sea during Summer Monsoons

By Ethan Wright

Description: The Northern Arabian Sea seasonal circulation is dominated by monsoonal winds. Upwelling favorable southwesterly winds in the summer off the coasts of Oman and Yemen force cold waters to the surface, which is often advected offshore in the form of cold filaments. Filaments are significant as sources of both transported nutrients and biomass to open waters as well as important conduits for transfer of cold and fresh water from the coasts to the open Arabian Sea. The filament features are also associated with strong sea surface temperature gradients and surface currents, which can affect the wind stress patterns associated with the filaments. An overview of these features and the proposed air-sea feedbacks affecting filament development is presented, leading into the outstanding research questions and the proposed approaches for answering these questions.

NOTE: Please feel free to forward/share this invitation with other groups/disciplines that might be interested in this talk/topic. All are welcome to attend.


ABSI Modeling Hydrographic Modeling Update

By Xu Chen and Steve Morey

Description: We have configured a high-resolution hydrodynamic model for Apalachicola Bay, FL and implemented an oyster larvae model to study the transport of oyster larvae from spawning areas to suitable juvenile habitat (settlement zones) in the bay. As one of the most ecologically diverse areas in the southeastern United States, Apalachicola Bay has also been a central economic pillar of the region with its oyster production industry. The salinity field in Apalachicola Bay has been found to be closely related to the oyster population dynamics. The model results forced by observed river discharge are compared with observations of water level, temperature, and salinity, to verify the simulation’s accuracy. However, we found when the river discharge is low, there is a significant salinity bias between the model and the observation. In this study we proposed and tested the approaches to eliminate the salinity bias. The oyster model is also improved by applying an updated mortality rate.
