The live feed to Nahant from Fabien Cousteau’s Mission 31 is scheduled for next Tuesday at 7 p.m. at the Northeastern University Marine Science Center on Nahant Road as part of the Summer Cinema by the Sea series. Previous announcements had it scheduled on a different day. A number of faculty and students from the center will participate in the mission, a monthlong underwater expedition that pays tribute to a similar mission by Cousteau’s famed grandfather, Jacques-Yves Cousteau, 50 years ago. Northeastern professors Brian Helmuth and Mark Patterson are science advisers, and the center’s ocean genome legacy director, Dan Distel, and assistant professor Loretta Fernandez are also involved in mission research. The center’s Three Seas Program coordinator and dive safety officer, Liz Bentley Magee, will spend two weeks in the underwater habitat. Also participating in underwater and/or topside support are graduate students Allison Matzelle, Nick Colvard, Amanda Dwyer, Jessica Torossian, and Chris Marks; undergraduate Felicia Aronson; and research technicians Francis Choi and Sara Williams. Bentley Magee will both blog and tweet on the mission, which is on Facebook and Instagram. There are also four scheduled mission-to-land talks at the Museum of Science in Cambridge, on June 22, June 26, June 28, and June 29.
