Speaker Irina Rypina, Ph.D., Assoc. Scientist, Woods Hole Oceanographic Institution Aggregation of slightly buoyant microplastics in 3D vortex flows Abstract Marine microplastic pollution is a rising concern for the ocean environmental and human health. The highest concentrations of microplastics are found at the ocean surface, but significant amounts are also observed at depth. What sets […]

Speaker Stephen Griffies, Geophysical Fluid Dynamics Laboratory, NOAA and Princeton University Ocean climate modeling with the MOM6 Lagrangian vertical coordinate model Abstract This talk provides a primer on the Lagrangian vertical remapping method as realized in MOM6. Additionally, we consider case studies whereby the vertical Lagrangian approach has been used for the study of ocean climate, […]

Speaker J. Xavier Prochaska, professor, UC Santa Cruz Lessons Learned from Applying Machine Learning to Remote Sensing Observations of Sea Surface Temperature Abstract I will describe lessons learned from our team’s program to apply machine learning to large remote sensing datasets of sea surface temperature (SST) on submesoscales (i.e. ~10-100km). Adopting unsupervised techniques, we first […]

Speaker Lilian Dove, Postdoctoral Fellow, Brown University Secrets of the Southern Ocean: Investigating Ocean Ventilation Using Underwater Autonomous Vehicles Abstract The Southern Ocean exerts a strong control on global climate as the primary site of both deep water ventilation and subduction of newly formed intermediate water masses. Thirty years of satellite altimetry has shown that […]

Speaker Brandon Reichl, NOAA Geophysical Fluid Dynamics Laboratory Improved representation of upper ocean vertical mixing in equatorial regions in ocean climate models Abstract Deficiencies in upper ocean vertical mixing parameterizations contribute to equatorial upper ocean biases in global coupled general circulation models, affecting their simulated ocean heat uptake and ENSO variability. To better understand these […]

Speaker Professor J. Xavier Prochaska, UC Santa Cruz Sea Meets the Stars: How AI is Accelerating the Scientific Pursuit Abstract In less than 10 years, advances in artificial intelligence (AI) have built systems to distinguish cats from dogs, translate English to Japanese, and record your sentiment on Facebook. With the appearance of chat-bots, AI has […]

Speaker Georgi Sutyrin, Emeritus Marine Research Scientist, GSO The Rossby waves and long-lived vortices: enemies or friends? Abstract Mesoscale variability is known to dominate the oceanic kinetic energy (KE) playing a major role in the general circulation and climate change. External forcing creates basin-scale oceanic gyres with sloping isopycnals, providing a major energy source for […]

Speaker Viviane Menezes, Asst. Scientist, Woods Hole Oceanographic Institution Deep Madagascar Basin Experiment: Antarctic Bottom Water Spreading in the Southwestern Indian Ocean Abstract This presentation will discuss the Deep Madagascar Basin (DMB) Experiment that began in 2023. The DMB aims to understand the Antarctic Bottom Water (AABW) pathways from the deep fracture zones of the […]

Speaker Bronwyn Cahill, Leibniz Institute for Baltic Sea Research, Warnemünde Deconstructing co-occurring marine heatwave and phytoplankton bloom events in the Western Baltic Sea in 2018 Abstract Between May and August 2018, two separate marine heatwaves (MHWs) occurred in the Arkona Sea in the western Baltic Sea. These heatwaves bookended an extended period of phytoplankton growth […]

Speaker Benjamin Barr, Postdoctoral Fellow, Woods Hole Oceanographic Institution Seastate-Dependent Sea Spray Heat Fluxes and Impacts on Tropical Cyclone Structure and Intensity Using Fully Coupled Atmosphere-Wave-Ocean Model Simulations Abstract Air-sea fluxes of sensible and latent heat are fundamental to the energetics of tropical cyclones (TCs) and their intensity. The contributions of sea spray to air-sea heat […]
