Oceanography Graduate receives NASA New Investigator Award

Building off of her Ph.D. and postdoctoral research in Marine Sciences, Kaylan (Kate) Randolph, from the Dierssen COLORS Lab, was recently awarded a NASA New Investigator Program in Earth Sciences grant to characterize the hyperspectral reflectance of breaking waves with subsurface turbulent kinetic energy dissipation rates, and air entrainment as a function of physical forcing conditions. Kate (pictured on the R.V. Laurence Gould in Punta Arenas, Chile with collaborator Ale Cifuentes-Lorenzen) will be deploying above-water autonomous hyperspectral radiometers from the Air-Sea Interaction Tower at Martha’s Vineyard Coastal Observatory (WHOI). These measurements will be paired with subsurface acoustical and optical instrumentation to tackle the physics behind ocean color. Kate’s ongoing efforts to study ocean surface physics also include active collaborations with Chris Zappa at Lamont-Doherty Earth Observatory and Ale Cifuentes-Lorenzen at UConn (pending NSF).



There’s so much Plastic in the Oceans Scientists Want to Study it from Space

Meghan Bartels from Newsweek recently interviewed University of Connecticut professor Heidi Dierssen for an article detailing the potential to use satellite imagery to estimate floating marine plastics. Dr. Dierssen recently published a paper with her postdoctoral student Dr. Shungu Garaba in Remote Sensing of the Environment analyzing the spectral properties and potential for remote sensing of marine macro- and microplastics as part of a NASA-funded project for the proposed hyperspectral satellite mission PACE.   Bartels writes:  “To know that it’s actually plastic and not something else floating or even a bubble or a whitecap, we have to have more of a sense of the spectral fingerprint and what’s unique to plastics,” Dierssen said. “It’s going to be very challenging.”

Where Gases Go: Observing Southern Ocean Air-Sea Flux

Professor Heidi Dierssen and postdoctoral scholar Dr. Kaylan Randolph were coauthors on a new paper in the Bulletin of the American Meteorological Society describing a large interdisciplinary experiment airborne campaign in the Southern Ocean.  They evaluated satellite and airborne remote sensing measurements to investigate biogeochemical and physical processes driving air–sea exchange of CO2, O2, and reactive biogenic gases in the Southern Ocean.

Tracking Connecticut’s Living Shoreline

The ocean is filled with a myriad of life forms, but many people don’t think of the shoreline itself as “living.” Through a new project, James O’Donnell, a professor of marine sciences at the University of Connecticut, and collaborators from Sacred Heart University will collect data and develop statistical measures to improve tracking of Connecticut’s living shoreline projects.

2018 Ocean Sciences Meeting well attended by UConn Department of Marine Sciences

Almost 30 members of the Department of Marine Sciences attended the 2018 Ocean Sciences Meeting in Portland, Oregon last month. The weeklong conference (February 11-16, 2018) brought together close to 4,000 attendees and covered all topics of oceanography, and other related fields. Many graduate students presented posters and gave oral presentations throughout the week. Professors, post-docs, and research staff presented their work as well. A handful also attended the 4th US Ocean Acidification PI Meeting held the days following the conference.
