Expedition ANTARCTIC BLANC (www.AntarcticBlanc.com) sets sail on 12th February 2018 on a 66-foot yacht in Puerto Williams (Chile). The destination is the the Western Antarctic Peninsula region, one of the fastest-warming places on Earth.
Zooplankton samples will be collected for genetic analysis by metabarcoding (DNA sequencing of unsorted samples for a “DNA barcode” gene region). DNA from each sample will be archived at the Ocean Genome Legacy Center (https://www.northeastern.edu/ogl/).
Metabarcoding allows rapid assessment of the zooplankton assemblage and pelagic food web, and better understanding of ecosystem responses to climate change.
This past November, a group of graduate students from the Department of Marine Sciences attended the 24th Biennial Conference of the Coastal and Estuarine Research Federation (CERF) in Providence, RI. Many prepared either poster or oral presentations for sharing throughout the week, ranging from topics of citizen science to salt marshes. Professors also attended, presented, and convened sessions including: Jaime Vaudrey as the Chair of the Scientific Program Committee, James O’Donnell, Michael Whitney, Hannes Baumann. The full scientific program of the conference can be found here.

Tyler Griffin joins the Oceanography graduate program with a UConn Outstanding Scholars Program Fellowship award. The primary goal of the OSP Fellowship is to recruit and enhance the most academically qualified and promising students entering UConn who are applying to doctoral programs. OSP recipients represent the very best of the entering graduate student class applying to doctoral programs. Tyler will be working towards a doctoral degree with Dr. Evan Ward (http://web.uconn.edu/jevanward/index.htm).
WASHINGTON – U.S. Senators Richard Blumenthal (D-Conn.) and Chris Murphy (D-Conn.) and U.S. Representative Joe Courtney (CT-2) announced on Tuesday that the University of Connecticut (UConn) was awarded a Marine Debris Research Grant totaling $257,531 from the National Oceanic and Atmospheric Administration (NOAA) Marine Debris Program. The Marine Debris Program is a competitive grant process. UConn will conduct research on the effect of marine debris, like plastic, on oysters from August 2017 through October 2019.
“Our state depends on a clean Long Island Sound, and UConn has been on the forefront of protecting it and supporting marine businesses. This federal grant will help UConn students and professors do even more. It will support invaluable research on the effects of ocean plastic on shellfish,” said Blumenthal, Murphy, and Courtney. “Connecticut’s oyster fisheries are an important part of the Southeastern Connecticut economy, and they depend on clean oceans. We look forward to reviewing the research over the coming years as we continue to fight for policies in Washington that protect the Sound.”
“We are proud to receive this grant. Plastic debris can have profound impacts on marine life. Microplastics, produced by the weathering of debris, can be taken up by shellfish. Our research will examine what types of plastic particles are ingested by oysters in Long Island Sound, might cause them harm, and might be passed up the food chain to humans. The study connects the health of Long Island Sound to safe and sustainable seafood,” said Dr. J. Evan Ward, Professor at UConn’s Department of Marine Sciences in Groton.

UConn Marine Sciences was well represented at the 13th International Conference on Copepoda (http://13icoc.org/), July 16-21, Los Angeles, USA. The conference was attended by scientists from 30 countries and dealt with all aspects of copepods (tiny crustaceans that are the most abundant animals on the planet).
PhD student Matthew Sasaki received the very first prestigious Kabata award for best student oral presentation for his talk, The remarkable thermal generalist performance curve of Acartia tonsa: Implications for survival in a warming climate. PhD student James deMayo received an award for outstanding poster for his presentation, Combined effects of warming and acidification on life-history traits of Acartia tonsa, and visiting PhD student Érika Pinho Correia (Federal University of Pernambuco, Brazil) also received an award for outstanding oral presentation for her talk, Is there any pattern of diel vertical migration of microzooplankton in the equatorial Atlantic?. All three students are members of Professor Hans Dam’s research group ( http://marinesciences.uconn.edu/faculty/dam/).
Warm congratulations to Matt, Jimmy and Erika!

Dr. Senjie Lin and his current and former Ph. D. graduate students, Brittany Sprecher and Yunyun Zhuang, engaged in an international collaboration to sequence Porphyra umbilicalis’ nuclear genome. Their efforts revealed how the red algae has been able to thrive in the harsh intertidal zone under exposure to high UV radiation, changing temperatures, and severe osmotic stress and desiccation for more than a billion years. Porphyra umbilicalis belongs to an ancient group of red algae, Bangiophyceae, and is a valuable human food source.
The team’s analysis found that P. umbilicalis has a small set of cytoskeleton motor proteins (explaining why red algae are smaller in size when compared to most multicellular lineages), several cellular mechanisms to cope with the stressful environment, and a high capacity for nutrient uptake and utilization.
Major support for the genome sequencing was through a contract with the U.S. Department of Energy’s Joint Genome Institute, sequencing analysis was supported by a National Science Foundations Research Collaboration Network grant, and the project was led by Dr. Susan Brawley at the University of Maine. The findings are published by Proceedings of the National Academy of Sciences.
