Speaker Pierre Chabert, Postdoctoral Research Associate, Brown University Two Case Studies: Coastal Impacts of Synoptic Winds Abstract Case 1) Eastern Boundary Upwelling EcosystemCase 2) New England Coastal Sea Level Extremes The theme of this presentation is the impact of synoptic-scale winds on the coastal ocean, focusing on two distinct areas and research questions. The first […]

Bio@Noon Seminar, November 6 – Maria Pachiadaki, Ph.D., Assistant Scientist II, Woods Hole Oceanographic Institution
Speaker Maria Pachiadaki, Ph.D., Assistant Scientist II, Woods Hole Oceanographic Institution Dark ocean chemoautorophy and other tales from tiny organisms with big impact Abstract Microbial inhabitants of the dark ocean (i.e. ocean water below the sunlight surface layer) comprise one of the largest biomes on Earth. They mediate all major biogeochemical cycles, control the “dark […]

Speaker J. Thomas Farrar, Ph.D., Senior Scientist, Woods Hole Oceanographic Institution The Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) Abstract The Sub-Mesoscale Ocean Dynamics Experiment (S-MODE) is a NASA Earth Ventures Suborbital investigation designed to test the hypothesis that oceanic frontogenesis and the kilometer-scale (“submesoscale”) instabilities that accompany it make important contributions to vertical exchange of climate […]

Speaker Agata Piffer Braga, Ph.D. candidate, UMass-Dartmouth Frontal Evolution of a River Plume: Dynamics, Turbulence, and the Release of Solitary Waves Abstract Fronts are a common and crucial feature of our oceans, driving vertical transport and playing a key role in oceanic mixing. In coastal regions, river plume fronts can form from the interaction of […]

Speaker Mak Saito, Senior Scientist, Woods Hole Oceanographic Institution The Adaptive Capabilities of Phytoplankton and Microbial Metallomes in a Changing Ocean Abstract Micronutrients play important roles in modern oceanic biological processes. Yet their use in biology is diverse and has been influenced by the surrounding environment, with major changes in metal availability occurring over Earth […]

Speaker Shafer Smith, Ph.D., Professor of Mathematics and Atmosphere/Ocean Science, New York University Sensing Sub-Mesoscale Structures from SWOT Abstract The Ka-band Radar Interferometer (KaRIn) aboard NASA’s recently launched Surface Water Ocean Topography (SWOT) satellite measures sea surface height (SSH) in 120 km wide swaths. Far exceeding its engineering expectations, the instrument is resolving SSH features […]

Speaker James F. Holden, Professor, UMass Amherst, Dept. of Microbiology Autotrophy and competition among thermophiles from hydrothermal vents Abstract Thermophilic methanogens and some sulfur reducers in hydrothermal vents can fix CO2 usingH2 as an energy source. However, our understanding of how and where these organisms grow in the sub seafloor, their biogeochemical impact, the isotopic […]

Speaker Elizabeth Weidner, Ph.D., Assistant Professor of Marine Sciences, University of Connecticut Echoes from the ice-ocean interface: High-frequency broadband acoustic study of tidewater glaciers Abstract The ice-water interface of marine-terminating (tidewater) glaciers in high latitude fjords represent a critical transition zone, linking the terrestrial, cryosphere, and ocean systems. These glaciers are important drivers of global […]

Speaker Rebecca Jackson, Asst. Prof., Earth and Climate Sciences, Tufts University Where glaciers meet the ocean: testing theories for submarine melt with observations from autonomous vessels Abstract Around the globe, glaciers and ice sheets are shrinking, raising sea levels at an accelerating rate. Ocean warming has been implicated as a driver of glacier retreat, with […]

Speaker Daniel Watkins, Ph.D., Senior Research Associate, Brown University Observing air-ice-ocean coupled dynamics: Results from the MOSAiC expedition and beyond Abstract Sea ice mediates the exchange of momentum, heat, and moisture between the atmosphere and the ocean. During the year-long MOSAiC expedition, an array of drifting buoys surrounding the R/V Polarstern enabled the characterization of […]
