The National Oceanic & Atmospheric Administration recently announced its approval of a network of state-owned properties and coastal waters in Lyme, Old Lyme, and Groton to be the site of the state’s first National Estuarine Research Reserve (NERR).

Nine graduate students shared their research at the 2020 Ocean Sciences Meeting in San Diego, California. A total of 22 presentations were given by DMS faculty, postdocs, and students. Besides the science, folks visited the La Jolla beaches and San Diego Zoo, ate delicious Mexican food, and networked with colleagues. We’re looking forward to more conferences and sharing our science!

Of the nitrogen delivered to Long Island Sound (LIS) using a 20 year time series, Vlahos, Whitney, and colleagues Found 40% of it is exported as primarily organic nitrogen (70% vs 30% as nitrate). However, 60% of the nitrogen Entering the LIS is either buried in sediments and/or denitrified to nitrogen gas and N2O.
The Department of Marine Sciences is excited to be well represented at Ocean Sciences 2020 in San Diego next week. With 22 presentations by faculty, students, and researchers and an exhibition booth, there are lots of ways to find out more about our research and opportunities in our department. See the full list of presentations below.
Former Marine Sciences graduate student, Dr. Maria Rosa, named as an Emerging Scholar by Diverse: Issues In Higher Education magazine (https://diverseeducation.com/2020-emerging-scholars/). For the past 19 years, Diverse: Issues In Higher Education has recognized an interdisciplinary group of minority scholars who represent the very best of the U.S. academy. Emerging Scholars are selected from hundreds of nominations, and those professors selected have distinguished themselves in their various academic disciplines and are actively working to make our society more equitable and just. This year, former Marine Sciences graduate student, Maria Rosa was one of fifteen professors nation-wide selected for the honor. Maria completed her PhD degree in 2016 (major advisor: Dr. J. Evan Ward), spent two years as a NSF-funded postdoctoral scholar at Stony Brook University (mentor: Dr. Dianna Padilla), and is currently the George and Carol Milne Assistant Professor of Biology at Connecticut College.
9 December 2019. During the COP25 summit in Madrid, the International Union for Conservation of Nature (IUCN) released its latest comprehensive report titled “Ocean deoxygenation: everyone’s problem” that compiles the current evidence for the ongoing, man-made decline in the oceans oxygen levels. The 588 page, 11 chapter wake-up call to these detrimental changes was produced by leading experts in the field. UConn DMS faculty Baumann is one of the co-authors in chapter 6 “Multiple stressors – forces that combine to worsen deoxygenation and its effects”.
From the executive summary:
“The equilibrium state of the ocean-atmosphere system has been perturbed these last few decades with the ocean becoming a source of oxygen for the atmosphere even though its oxygen inventory is only ~0.6% of that of the atmosphere. Different analyses conclude that the global ocean oxygen content has decreased by 1-2% since the middle of the 20th century. Global warming is expected to have contributed to this decrease, directly because the solubility of oxygen in warmer waters decreases, and indirectly through changes in the physical and biogeochemical dynamics.”

MARN 4001 students presented their work on local water quality at the Cottrell Brewery.
Researchers at UConn and U Vermont carry out experimental evolution studies to assess the scope for evolution of marine zooplankton under greenhouse (high temperature and high CO2) conditions. They explain their approach in a lay-audience video (https://www.youtube.com/watch?v=YrI2188-ejM&feature=youtu.be).
Professor Samantha Siedlecki was recently featured in UConn Today, a wide audience publication produced by the university’s Office of Communications. The article highlights her background and cutting-edge research projects.
21 November 2019. Members of the Evolutionary Fish Ecology lab (befel.marinesciences.uconn.edu) are excited to announce that Conservation Physiology has just published our ground-breaking research on the unusual, high sensitivity of Northern sand lance embryos to acidification and warming. Dr. Chris Murray, who recently graduated from UConn with his Ph.D. and now pursues his post-doctoral research at the University of Washington, is the lead author of this study, which was funded by a Northeast Regional SeaGrant project and conducted in collaboration with NOAA colleagues from Stellwagen Bank National Marine Sanctuary.
Our study suggests that organisms that develop slowly in offshore, temperate/subpolar habitats are likely most vulnerable to the combined effects of increasing temperature and acidification in the ocean.
