First Annual Nantucket Green Crab Derby with the Nantucket Maria Mitchell Association

Kelly Bernatzky • July 20, 2021

As part of the Second Annual Nantucket Green Crab Week, the Nantucket Maria Mitchell Association (MMA) hosted the first ever Nantucket Green Crab Derby on July 16. Nantucket Green Crab Week is a collaboration between the MMA and Nantucket Land Council (NLC), offering a full week of daily activities to learn about and take action against invasive European green crabs on Nantucket.

 

European green crabs were first introduced to North America in the 1800s, likely traveling in ballast water of merchant ships from Europe. This invasive species is now abundant on Nantucket, threatening crucial aquatic resources, including eelgrass beds, shellfish populations, and native crab communities here on the island.

 

Together with thirteen active teams and forty-nine participants, the Nantucket Green Crab Derby collected over 650 individual green crabs weighing approximately thirty-one pounds. Considering females can release up to 185,000 larvae per season, the Derby may have prevented up to 60 million larval baby green crabs from entering Nantucket’s waters this year!

 

The grand prize winning team, “Crabby Middle Schooler,” collected 7.4 lbs. of green crabs. The second place team, “Nana Claws,” was very close with 6.2 lbs. and the highest number of individual crabs, totaling 232. The largest crab prize went to “The Green Crab Hunters” who collected an enormous 5.0 oz. green crab. “The Bronner 4” took home the prize for Best Decorated Crab with their crab named “Tamatoa” featuring a jingle shell and barnacles. “Crabby Middle Schooler” received an honorable mention for their well-decorated crab, “Shelley,” featuring a well-placed jingle shell! Both “Tamatoa” and “Shelley” will be on display at the Maria Mitchell Aquarium.

 

Though Nantucket Green Crab Week is over, anyone is welcome to join the MMA’s Citizen Science project on Green Crabs by helping conduct Green Crab Surveys. The more submissions the MMA receives, the better we can target green crabs where they are most abundant, track their movement preferences, and see how they use Nantucket’s sensitive eelgrass beds. To participate and learn more about this invasive species, please visit the Maria Mitchell Association Green Crab Research webpage at https://www.mariamitchell.org/the-green-crab. 

 

The Maria Mitchell Association is a private non-profit organization. Founded in 1902, the MMA works to preserve the legacy of Nantucket native astronomer, naturalist, librarian, and educator, Maria Mitchell. The Maria Mitchell Association operates two observatories, a natural science museum, an aquarium, a research center, and preserves the historic birthplace of Maria Mitchell. A wide variety of science and history-related programming is offered throughout the year for people of all ages.

 

Nantucket Land Council is a 501(c)3 environmental advocacy organization – protecting and preserving open space, harbor, pond, and groundwater, and advocating for the environment at Select Board, Planning Board, and Conservation Commission meetings. The Nantucket Land Council also hosts the State of the Harbor Forum each year and Oysterfest each November to educate residents on the state of our water resources, and what we can all do to help maintain this critical resource.

Raise The Roof!

By Jascin N. Leonardo Finger • April 6, 2026
Well, actually replace the roof! With funding from the Community Preservation Act and the work of Lydon and Sons, Inc. the Mitchell House is getting a new roof. The current one had come to the end of its useful life. A cedar roof can last a long time – longer than asphalt – and is more historically accurate. The roof we are removing was installed in about 1992 – replacing a roof from the 1930s that was not cedar but a combination of materials that actually yes, did last sixty years. The unfortunate issue has arisen that the roofwalk (walk) has to be replaced. This is NOT the original walk – nor that old of a walk. It’s likely from the 1970s or so and has been cobbled at over time. It’s not a functioning walk – no one is allowed on it – but the Mitchell House needs it none the less. Maria Mitchell and her father, William, likely used the walk for astronomical observations – in addition to the yard – but the walk is also protected as part of the preservation easement on the House. Walks – NOT and NEVER called widow’s walks – were used for preventing and putting out chimney fire and roof fires. In a place where wood was expensive and had to be brought from “the main” these were purely utilitarian. What good Quaker (or non-Quaker) would build a platform for his wife to stare out to the harbor to see if her husband was on his way home? The other issue is that the walk was completely resting on the ridge board – and actually was notched to accept the pitch and tip of the ridge board so they couldn’t work around it. I suspect this may have been the ways walks were once built – and also a crafty and smart thinking carpenter who came up with the idea. It makes the walk lower. But between that issue and the age of the walk and then the blizzard of February 2026 that packed gusts over 83 MPH (that’s Category 1 hurricane winds) the walk gave in. Balusters had been knocked out and the railings were loose and pulling away from the posts. So, we will also be working with Barber and Sons to create a new roofwalk – and they agreed to do this for us quickly which is also no small feat given how busy everyone is these days. So from the bottom of the Mitchell House’s heart (and mine) a big thank you to Chris Lydon and Lydon and Sons and crew, Barber and Sons / Beau and Nate Barber, the Community Preservation Committee, and Nantucket Preservation Trust (our easement holder)!

Nantucket Maria Mitchell Association Welcomes Dr. Joshua Reding for “Dark and Quiet: Astronomy in the Age of Satellite Constellations” For April Science Speaker Series

April 1, 2026
NANTUCKET, MA—The Maria Mitchell Association (MMA) invites the community to “Dark and Quiet: Astronomy in the Age of Satellite Constellation” presented by Dr. Joshua Reding for its April Science Speaker Series. This free presentation will take place Wednesday, April 15 from 7 – 8pm on Zoom. In the past decade, the number of active satellites in Earth’s orbit has grown by a factor of 10. This breakneck growth in the commercial space industry has turned entrepreneur, investor, and policymaker eyes to the skies, but in the process has boxed out the historic stewards of the space domain: scientists. Explorers and pioneers across human history learned that uncharted territory hides unprecedented challenges, but the consequences of decisions made towards occupying the “final frontier” do not abide by international borders. Space operators therefore ignore the warnings and concerns of scientists not only at their own risk, but at the risk of everyone living under increasingly crowded skies. In this conversation, Dr. Josh Reding will explain how astronomers are trying to inform and guide policymaking for the rapidly changing space environment, both informally through volunteer action and advocacy and formally in domestic and international policy forums. Dr. Reding is an optical astronomer by training and now a radio spectrum manager by profession. He completed his B.A. with a double major in Astronomy-Physics and Philosophy at Colgate University, and his M.S. and Ph.D. in Physics from the University of North Carolina at Chapel Hill. His research investigated unusual white dwarf stars that likely formed in stellar mergers as “failed” supernovae and he has also designed astronomical instrument components and installed them at world-class observatories. Concurrent with the completion of his Ph.D., Reding began his professional science policy career as a North Carolina STEM Policy Fellow in the NC Department of Commerce’s Office of Science, Technology & Innovation. He was then selected for the American Association for the Advancement of Science Science & Technology Policy Fellowship, which places scientists in federal offices as expert contributors to ongoing agency missions. This event will be held via Zoom. Pre-registration is required. To register for the free, virtual event, use the registration link: https://us06web.zoom.us/webinar/register/WN_5MoAybp5QHCasQ0QE5xmgQ#/registration The Science Speaker Series is generously sponsored by the Maria Mitchell Association’s lead sponsor, Bank of America. The Maria Mitchell Association was founded in 1902 to preserve the legacy of Nantucket native astronomer, naturalist, librarian, and educator, Maria Mitchell. After she discovered a comet in 1847, Mitchell’s international fame led to many achievements and awards, including an appointment as the first professor of astronomy at Vassar College. Maria Mitchell believed in “learning by doing” and today that philosophy is reflected in the MMA’s mission statement, programs, research projects, and other activities. The Maria Mitchell Association operates two observatories, a natural science museum, an aquarium, a research center, and preserves the historic birthplace of Maria Mitchell. A wide variety of science and history-related programming is offered throughout the year for people of all ages. ###
