NOAA sanctuaries just published a little blurb online, introducing sand lance and it’s importance to the Stellwagen Bank National Marine Sanctuary, including a small section on the current research efforts funded by NOAA Regional SeaGrant.
“To that end, the team is collaborating with scientists from the University of Connecticut (UConn). UConn study members transport live-caught sanctuary sand lance to their lab, where further generations of sand lance are raised. The resulting larval sand lance are raised in high-tech rearing facilities that can be adjusted to mimic future ocean conditions.”
4th time’s the charm: sampling spawning ripe sand lance on Stellwagen Bank
Early morning on 2 December 2016, we left Scituate, MA, for the forth time this year, heading towards Stellwagen Bank in search of spawning ripe Northern sand lance (Ammodytes dubius), a winter spawning forage fish of great importance to the Stellwagen Bank National Marine Sanctuary and the object of latest research efforts. While during the last three cruises in late October and November, we saw a progression of ripening in the specimens, up to now we didn’t actually find spawning ripe individuals. Today, though, things are different, and when the first sand lance appear in our beam trawl, we immediately know that today we’ve been at the right time and at the right place.
It seemed an ambitious dream not too long ago, but now we’re happy report that we’ve started an experiment on sand lance embryos in our lab. Thanks to Chris Murray, David Wiley, Mike Thompson, captain Steve and his deckhand Matt for the successful trip!

October 10th 2016 was a special day for our still young lab here at the University of Connecticut, Today, the ICES Journal of Marine Science published the paper of Chris Murray et al., which is the first of hopefully many publications of our experimental findings originating out of our new laboratory facility here at UConn Avery Point.
Chris and his co-authors report on a large-scale, quantitative rearing experiment on Atlantic silversides eggs, larvae and juveniles under contrasting CO2 conditions that took place between May – September 2015. This novel experiment was designed to address three critical issues lacking in previous ocean acidification research on fish. First, the study spanned several ontogenetic stages. Second, it used very large numbers of individuals to robustly characterize not just potential shifts in mean responses, but also changes in the distribution of length, weight, and condition factor. Third, it provided food at standardized, non-excess levels to prevent that potential metabolic costs of high CO2 exposure could be compensated by survivors simply by eating more food.
Overall the study demonstrated seemingly small but significant growth reductions due to high CO2 and identified a small number of fatty acids that were of significantly different concentrations in high vs. control juveniles.
NOAA and Sea Grant fund $800,000 in research to understand effects of ocean changes on iconic Northeast marine life
The Ocean & Atmospheric Research program (OAR) of NOAA and Sea Grant just announced the winners of its most recent round of research funding to better understand the consequences of ocean warming and acidification on key marine resources in U.S. Northeast coastal waters. We are happy and proud that our proposed work on the climate sensitivity of Northern sand lance (Ammodytes dubius) was one of the four projects selected for funding. This is particularly good news for Chris Murray, who for his PhD can now expand his experimental rearing expertise to this important species.
This work will be conducted collaboratively with colleagues from NOAA (David Wiley), USGS (Page Valentine), Boston University (Les Kaufman), and Woods Hole Oceanographic Institution (Scott Gallager).
You can read the official announcement as it appeared on 6 September 2016 on NOAA’s News site.
This small conference brought together approximately 150 international scientists to talk about larval fish growth, survival, maternal effects, dispersal, systematics to name just a few. It was held in special honor of Edward Houde, who over his long career has inspired generations of marine scientists.
While Chris was presenting last years data about growth consequences of high CO2 exposure across life stages in our model species, the Atlantic Silverside, Hannes participated in the Early Career workshop and gave a talk about how to approach the writing of a scientific manuscript (PDF).
Jake reported back to his old undergraduate institution about his current research and how the University of Maine at Machias has inspired him to pursue a career in Marine Sciences.
This week’s Alumni Spotlight shines on Jake Snyder, UMM Class of 2014 with a degree in Marine Biology. Jake lives in Canterbury, Connecticut, and is a research assistant at the University of Connecticut’s Avery Point.
Tell us a little bit about what you are doing now:
Currently, I am a research assistant at UConn Avery Point as part of my masters. I was accepted into the graduate program here in the fall of 2015, and I am now working towards my Masters in Biological Oceanography. Our lab is small, with myself, a doctoral student, and our advisor, but we’re ambitious. Our research is focused on the synergistic effects of ocean acidification, increased temperature, and decreased oxygen on the Atlantic Silverside (Menidia menidia), a near-shore schooling fish. We’ve also recently started working with the Northern Sandlance (Ammodytes dubius), a fish native to Stellwagen Bank. In addition to the lab-based research, I am also digitizing the ~40 year data set collected by Project Oceanology, and developing that into a searchable database as part of the LISICOS (Long Island Sound Integrated Coastal Observing System) system.
A big shout-out to Megan, Rainer, and Liz who apart from their intrepid work as volunteers in our lab also excelled here in their video project for MARN3000. They interviewed Profs. Kelly Lombardo, Michael Finiguerra, and Hannes Baumann about aspects of Marine Climate Change and then cut their answers with researched video material from the web. Note the sartorial touch throughout the clip (6 min)!
Well done, all!
On 13 April, Hannes was invited to the board meeting of the Mumford Cove Association to present a brief update about our groups research activities in and around the cove. It is part of our commitment to public education and outreach to keep property owners informed and maintain good relationships with all parties involved.
The information material below contains graphical summaries of our activities, i.e., measuring water quality parameters continuously with a logging probe and conducting biweekly beach seine surveys for silversides.
On 15 March, Hannes gave a lecture at Mitchell College in New London, talking about the combined effects of ocean warming, acidification, and hypoxia on marine organisms. The entire lecture is publicly available at Limnology & Oceanography e-lectures.
“It was such a pleasure to have you present to the class today; your lecture was excellent – engaging with just the right amount and level of information. I’m glad that you intend to continue to provide outreach/education to the community on this topic.”
