Scientists at our Milford Lab are raising multiple generations of bay scallops under different projected ocean acidification conditions. They want to see if bay scallops can adapt and acclimate to projected ocean conditions and if each generation’s survival and growth is better than that of the previous generation.
This work can be used in a couple of different ways. One is to estimate how bay scallop populations will respond to future ocean conditions to help identify populations and regions that may be the most vulnerable. Another way is to inform the aquaculture industry on how future ocean conditions may affect the hatchery, grow-out, and adult phases of farmed bay scallops. There's also a genetics component to their study. They’re hoping to identify traits that make an individual more resilient to ocean acidification so they can breed bay scallops specifically for their resiliency.
Common Thresher Shark
Common thresher sharks are found in temperate waters around the world. In the northwest Atlantic Ocean, they range from Newfoundland to Cuba. While they can grow to about 18 feet long, about half of their total length is all fin. Their long sickle-shaped caudal fin is one of the most distinguishing characteristics of thresher sharks. What’s really fascinating is how they use their long caudal fin like a whip to stun fish while hunting for food.
Our Apex Predators Program conducts life history research and long-term monitoring activities essential for the assessment and management of this species. One of the ways we learn about the life history of common thresher sharks is through our Cooperative Shark Tagging Program. It’s the longest continuous shark tagging program in the world, started in 1962. It is a collaborative citizen science effort that engages thousands of recreational and commercial fishers.
In more recent years, between 2019 and 2021, 31 common thresher sharks were tagged through our program. The largest common thresher shark tagged during that time was a female measuring about 14 feet long. She was caught off Montauk, New York, in September 2019. The farthest tagged common thresher shark during that time was a female caught within the English Channel off the Isle of Wight, England, in July 2020.
Another opportunity to collect shark data is when they wash ashore. Thresher sharks can tolerate cold temperatures, but they’re not immune to cold shock. This can happen during the winter months when they get trapped in shallow areas as the tide rolls out and temperatures drop. This is known as the “fish trap effect” and it may have been what happened to one unfortunate juvenile male that washed up on Cape Cod in February 2022. Scientists from our Apex Predators Program were notified and quickly headed to its location so they could collect tissue samples to better understand the genetics, habitat use, diet, age range, and reproduction of this species.
Harbor seals can be found along the U.S. East and West Coasts. They’re commonly seen resting on rocks and beaches with their head and rear flippers elevated into a banana-like shape. Harbor seals, like all marine mammals, are protected under the Marine Mammal Protection Act—an act that celebrates its 50th anniversary on October 21, 2022. Another reason to celebrate harbor seals in 2022: the return of harbor seals to our Woods Hole Science Aquarium! After 5 long years, in 2022 we welcomed two harbor seals named Bubba and Kitt. While they’ve been settling in at our aquarium, their personalities have really developed. Bubba is a true gentle giant, very tolerant, laid back, and just goes with the flow. Kitt is playful, inquisitive, and a total ball of energy. If you’re planning a trip to see Bubba and Kitt and our other aquarium residents, be sure to check our website, Facebook, and Twitter for the most up to date information about hours of operation, closures, and more.
October 21 marks the 50th anniversary of the Marine Mammal Protection Act. What better way to celebrate that milestone than with a humpback whale jack-o’-lantern? Congress passed the Marine Mammal Protection Act in 1972 in response to growing concerns over significant declines of a number of marine mammal species. Some were even in danger of extinction. Because marine mammals are vital to the balance of marine ecosystems and are key indicators of the overall ocean health, it’s important that we protect and conserve them. Since the Act was enacted, declines of many marine mammal populations have slowed. It’s also led to the recovery of several populations, including gray seals, California sea lions, gray whales, and humpback whales.
- If you have fairly large areas that you're carving away, score the skin of the pumpkin with a bunch of "x" or hash patterns using a knife and then use your carving tool(s) to shave away the pumpkin skin. Pumpkin skin is tough and scoring it makes it easier to remove that tough top layer.
- Picking the right pumpkin: you want to pick pumpkins with green stems. Those with the greenest stems were harvested most recently and will last longer.
- Generally, the thickness of the stem directly relates to the thickness of the wall of the pumpkin. Thin-walled pumpkins tend to have thin stems while thick-walled pumpkins tend to have thick stems.
- You can prolong the life of the carved pumpkin by applying a thin coat of vaseline to the cut/carved areas and/or store it in the fridge. Smoothing the inside instead of leaving it rough is also said to extend the life of a jack-o’-lantern, delaying decay.
- The right tools make carving a breeze! For cutting out pieces, those pumpkin carving kits with the little saws are a dream.
- Accidents happen. If part of the design breaks off, there are ways to fix it. If there’s a break, you can fix it with toothpicks, super glue, or both. For the super glue method, simply dry off the excess moisture from the broken area. Then add super glue to the broken area, affix the broken piece and hold them together for a few moments until the glue takes effect. For the toothpick method, take a couple toothpicks, trim them shorter if needed, and use them to kabob the broken piece back in place.
- If you use permanent markers (like a Sharpie) to draw on pumpkins, you can remove leftover marker using regular household rubbing alcohol and a cotton ball, cotton swab, paper towel, or similar.
