Jesica Waller’s paper on the effects of warming and OA on lobster larvae was recently published in ICES J Mar Sci. She defends her thesis the day after tomorrow (Thu Nov 17th)! In 2017 Rick Wahle (UM), David Field (Bigelow) and Spencer Greenwood (UPEI) will be starting their newly funded regional SG project to continue this work with a new graduate student by looking for evidence of local adaptation to warming and OA across subpopulations of lobsters spanning New England’s steep North-south thermal gradient. 

David Fields (

In addition to our work on larval lobsters that Rick listed above, we are continuing our work on the effects of climate change on copepods. We have 2 recent papers on the effects of OA on morphology and physiology of marine copepods in the North Atlantic/Arctic (both in ICES-2016) and a third in review on genetic changes in copepods due to OA effects.  We are also investigating changes in the biogeography of copepods species in the North. Atlantic and its impact of hybridization of species (proposal pending).

Friends of Casco Bay is offering a two-session course to 16 educators on November 2 & 16 on "A Changing Casco Bay." The workshops include classroom activities, children's books, and background readings on the local impacts of climate change, with a focus on estuaries and the Gulf of Maine.

Mike Doan (

Friends of Casco Bay continues to monitor water quality, including pH, through our citizen steward and water column profile programs, each of which are in their 24th year of collecting data. In addition, we have started a new program that measures water temperature, salinity, dissolved oxygen, pH, and pCO2 on an hourly basis year-round at one site in Casco Bay. We hope to expand this program to a second site in the near future. We also worked with Dr. Brian Beal on a sediment pH measurement project, looking into the potential benefits of various buffering materials on a clam flat.

Jack Reynolds, a student in the University of Maine’s Semester by the Sea program is studying how variable near shore acidification is at a variety of microhabitats and over time.  He is recording much higher changes in pH within a day within a tidepool than is predicted to occur in the open ocean over the next century.  His study is ongoing.
