Antonio Mannino had been at sea for more than a week, collecting samples of seawater and plankton and measuring the conditions in the North Atlantic Ocean. It was not exactly a luxury cruise, but to understand the planet’s biggest food source—phytoplankton—and perhaps its most important sink for carbon dioxide, you’ve got to get out on the water.
As is common in late autumn—when cold north winds of winter battle for supremacy of the North Atlantic against the lingering warm fronts of summer—the weather grew messy. Seas churned with waves rising seven to fourteen feet, and Mannino and colleagues struggled to cast water samplers and nets over the sides of the Delaware IIresearch vessel. After several days, the foul weather made it impossible to work, and the captain began steaming back from Georges Bank toward Provincetown, Massachusetts. He planned to lay anchor in the (hopefully) calmer waters of Cape Cod Bay and ride out the storm.
Mannino, an oceanographer from NASA’s Goddard Space Flight Center, was sitting in the ship’s galley, while graduate student Dave Munro dozed on a nearby couch. It was Friday the 13th.
Thud. Splash. Slosh.
A wave crashed through the porthole window, knocking out the glass and dousing Munro in a bath of seawater. A few tens of gallons sloshed around on the galley floor as the crew sealed the porthole hatch. No one was injured, and the ship was never in serious danger, but it was enough to send them back to port in Woods Hole.
The 155-foot Fisheries Survey Vessel Delaware II, operated by the National Oceanic and Atmospheric Administration (NOAA), is a 40-year-old workhorse. Spare parts are not exactly lying around on a shelf. So the crew did what seamen do: they bolted steel plates over the porthole, soldered things shut, and got back out to sea. There was research to be done, and time spent in port is time and money lost.

Mannino and colleagues from NASA, NOAA, and Old Dominion University headed back out into the North Atlantic for another week, sharing cramped quarters, cozy labs, and choppy autumn seas to see how those turbulent waters influence the tiniest and most important ocean life forms.
