A long-running study of tiny organisms off New England is set to resume due to an agreement between scientific organizations. The survey, which originally ran from 1961 to 2017, will resume because of an agreement between the National Oceanic and Atmospheric Administration’s Northeast Fisheries Science Center and the Woods Hole Oceanographic Association in Woods Hole, Massachusetts, and the Marine Biological Association in Plymouth, England.
Don’t be fooled by phytoplankton’s microscopic size, the creature is among the most vital organisms for the ocean and planet’s survival.
With still so much to learn about the planktonic creatures that support the marine food web, scientists with the Northeast U.S. Shelf Long-Term Ecological Research (NES-LTER) project have developed the In-situ Ichthyoplankton Imaging System (ISIIS) to take better images of these microscopic organisms in their natural environmentRead More
This video explains the key physical, biological and ecological processes in oases on the Antarctic icy coast — polynyas. Researchers at Woods Hole Oceanographic Institution and the University of Delaware are trying to unveil crucial connections among the physical and biological components in the polynyas and to understand how the Antarctic ecosystem responds to changes in the large-scale environment.Read More

Lava-driven nutrient fountains “could be a pretty important driver of phytoplankton ecology in the broader ocean,” said Harriet Alexander, a biological oceanographer at the Woods Hole Oceanographic Institution who was not involved in the latest study.
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.Read More
Harmful algal blooms can produce toxins that accumulate in shellfish and cause health problems and economic losses. They have increased in strength and frequency worldwide. Can we get advance warnings of when and where they will occur?Read More
What makes the shelf break front such a productive and diverse part of the Northwest Atlantic Ocean? A group of scientists on the research vessel Neil Armstrong spent two weeks at sea in 2018 as part of a three-year, NSF-funded project to find out.Read More
The twilight zone is a part of the ocean 660 to 3,300 feet below the surface, where little sunlight can reach. It is deep and dark and cold, and the pressures there are enormous. Despite these challenging conditions, the twilight zone teems with life that helps support the ocean’s food web and is intertwined with Earth’s climate. Some countries are gearing up to exploit twilight zone fisheries, with unknown impacts for marine ecosystems and global climate. Scientists and engineers at Woods Hole Oceanographic Institution are poised to explore and investigate this hidden frontier.Read More
Heidi Sosik, a senior scientist in the Biology Department at Woods Hole Oceanographic Institution (WHOI) has been named a 2018 Fellow of The Oceanography Society (TOS). Sosik’s accomplishments will be formally recognized on Feb. 13, 2018, during a ceremony at the 2018 Ocean Sciences Meeting in Portland, Oregon.Read More
