February 28, 2019 — The New Bedford Science Café returns Wednesday March 6 with fisheries biologist Megan Winton, a PhD candidate at the School for Marine Science and Technology (SMAST), UMass-Dartmouth.
His presentation, “You’re gonna need a bigger dataset: How statistics are shedding light on the secret lives of sharks,” is slated for 6 to 8 p.m. at Greasy Luck, 791 Purchase St., New Bedford. Open to everyone. Free, except for beer and food.
Little is known about the great white sharks that swim in these waters. Sharks are notoriously difficult to study in the wild, especially as they migrate vast distances, are elusive and difficult to capture, a press release about the event states. But, as Winton will relate, that’s changing thanks to the rapid development of electronic tags that are capable of recording a tagged shark’s location, movement patterns, and local environment. Scientists now have unprecedented volumes of information to make sense of.
How does the collected data tell scientists what an animal is actually up to? What can be revealed about the broader population? Since 2015, Winton has been working with the Massachusetts Division of Marine Fisheries and the Atlantic White Shark Conservancy to unravel mysteries about great white sharks off the coast of Cape Cod. As a quantitative fisheries biologist, she employs both math and her knowledge of species biology to gain insights into fish populations. The science, in the long run, can lend to better ways of protecting sharks and improving safety for humans.
