MIT-WHOI Joint Program Student Orientation Cruise, November 2023

In November 2023, a team of 20 MIT-WHOI Joint Program students steamed out on R/V Neil Armstrong for a 50h introductory research cruise. For many of them, this was the first time on a research vessel, conducting a multidisciplinary survey of the shelf and shelfbreak front south of New England. The PO department was strongly…
