Join us for a virtual seminar by Dr. Yackar Mauzole, Scripps Institution of Oceanography (UCSD). Her talk is titled "Synergy of Satellite Observations and Ocean Dynamics in the Bay of Bengal."

Date and Time: Tuesday, August 27, 2024 at 1:00pm EST

Join us via Teams Meeting

Abstract:

"The Bay of Bengal is a semi-enclosed basin located in the Northern Indian Ocean. The region is salinity-dominated and presents very complex and multi-scale dynamics, both on the oceanic and atmospheric side. One of the dominant features of the Bay of Bengal is the presence of monsoons, bringing large amount of rain seasonally. Monsoons are still poorly understood to this day, and more efforts are being led to fill in the puzzle they present through multi-institutions and multi-years initiatives, such as the Monsoon Intra-Seasonal Oscillation in the Bay of Bengal (MISO-BoB) project. Within the framework of the MISO-BoB project, a research cruise was conducted in summer 2019 in the Northwestern Bay of Bengal, and a coastal filament was observed during the month-long experiment. This observation raised several questions, namely 1) was this a one-time occurrence or a recurring event, 2) was this the only place to observe such process in the region, and 3) what caused this filament to appear. In addition to in-situ data, this study relied on satellite measurements of altimetry, and sea surface temperature, among other ocean variables to further the understanding of these features. Altimetry records from 1993 to 2023 highlight that coastal filaments were detected every year, but also that they could be seen off both the northwestern and southwestern coasts of the Bay, as well as south of Sri Lanka. The nature of these filaments, and their impact on the local ocean dynamics were also investigated."

Biography:

Dr. Yackar Mauzole is currently an Assistant Project Scientist at the Scripps Institution of Oceanography (UCSD), working in the Marine Physical Lab. She is a physical oceanographer specialized in satellite observations and submesoscale processes (fronts, filaments, eddies…). She focuses on analyzing large datasets across ocean variables, such as sea surface temperature (SST), sea surface salinity (SSS) or sea surface height (SSH). Originally from Paris - France, she moved to the US to attend grad school at the Graduate School of Oceanography of the University of Rhode Island. During her PhD, she developed a tracking algorithm for persistent SST fronts, named FRODO (Frontal Delineation in the Ocean), and applied to global datasets to detect long-term frontal patterns. Before working at Scripps, Yackar was a postdoc at JPL, where she modified the FRODO method to apply it on the MITgcm output and study frontal patterns in the California Current System. She is now working on submesoscale features in the Northwestern Bay of Bengal in the Indian Ocean, to better understand coastal filaments and their potential impact on the regional ocean dynamics.
