Logan Johnsen, chief mate on the research vessel Neil Armstrong, stood watch on the bridge recently during a mooring deployment at the Ocean Observatories Initiative (OOI) Pioneer Array. Instruments on the array record physical, chemical, and biological data from the seafloor to the surface and above around the clock, 365 days a year. Twice each year, a team from WHOI visits the Pioneer site, located about 100 miles south of Marthas Vineyard, to replace all of the moorings in the array and to deploy autonomous underwater vehicles that record data further afield.

Rapid Response at Sea
As sea ice continues to melt in the Arctic and oil exploration expands in the region, the possibility of an oil spill occurring under ice is higher than ever. To help first responders cope with oil trapped under ice, ocean engineers are developing undersea vehicles that can map oil spills to improve situational awareness and decision making during an emergency.

Three things you may not know about basking sharks:
1. The basking shark is the 2nd largest fish in the ocean.
2. While it’s gaping mouth can fit a human, it filter feeds on tiny plankton.
3. WHOI’s SharkCam captured the first Autonomous Underwater Vehicle (AUV) footage of basking sharks.

Minion robots in the Ocean Twilight Zone
Phytoplankton use sunlight and carbon dioxide to grow, forming the base of the ocean food web. Phytoplankton are eaten by zooplankton, which are eaten by other animals. Dead zooplankton and other particles become marine snow drifting in the ocean, but how much marine snow sinks below the sun-lit ocean surface? Scientists are developing a new device
that will follow marine snow into the ocean’s twilight zone.
The MINION is a small (2 Liters) inexpensive instrument. It is equipped with… cameras, seawater sensors, acoustic recorder, ballast weight. Once deployed, MINION will sink to the twilight zone and drift with currents.
Cameras on the side record the rate and quantity of particles falling through the ocean. Falling particles also accumulate on a clear glass panel. A camera on top will record the particle type and accumulation rate.
Similar images have revealed the twilight zone is a perpetual snowstorm, of organic debris. Particles such as this fecal pellet from a jellyfish-like salp are extremely carbon-rich. Pellets like this will sink quickly to deeper waters, or even become buried in the seafloor. Any marine snow that reaches the deep ocean means less carbon in the atmosphere.
The MINION is designed to listen for underwater sound sources. This will determine their location as they drift.
After a MINION has finished its mission, it will release weight and float to the surface. At the surface, it sends a homing signal so it can be recovered. The next generation of MINION will send compressed data-sets via satellite. Allowing them to be deployed by the dozens. Data from MINIONS will help scientists learn more about the ocean’s role in Earth’s climate system.

After several years, Kara Dodge began to do other work with turtles, in particular a “TurtleCam” project with Woods Hole Oceanographic Institution engineer Amy Kukulya. The project involved tagging and tailing turtles with autonomous underwater vehicles to study diving behavior, eating habits, and assess ways to reduce entanglements.
