Woods Hole Oceanographic Institution (WHOI) is the world's premier independent organization dedicated exclusively to ocean research, technology, and education. We combine state-of-the-art science, engineering, and ship operations to unravel the mysteries of the deep and devise science-based solutions to planet-wide problems.


It’s #WorldSeagrassDay!⁠
🐠 🐢🐬 As one of the most widespread coastal habitats on Earth, #seagrass meadows sustain some of the world’s largest fisheries, as well as provide food and shelter for turtles, marine mammals, seahorses, shellfish and crustaceans. These submerged meadows also act as natural water filters, keeping pollutants out of our seafood and protecting vulnerable coral reefs. Seagrass meadows store up to 18% of the carbon in the ocean and act as the first line of defense against coastal floods and storms.⁠
Despite all these incredible benefits, about a third of the seagrass around the world has disappeared. “Globally, a soccer field of seagrass is lost every 30 minutes,” says #WHOI marine chemist Matt Long, “and we lose about 5-10% at an accelerated rate every single year.”⁠

A marine #isopod dines on a mantis shrimp in a collecting tank. A relative of land-based pill bugs or roly-polys, there are thousands of these types of #crustacean in the #ocean. Some are scavengers, some are parasites, and some are filter-feeders, but they all play an important role in the carbon cycle that keeps our climate habitable.

This isopod was collected during a research cruise to the Northeast US Shelf Long-term Ecological Research Station as part of an effort to study #zooplankton along the highly productive continental shelf.

WHOI is at the forefront of groundbreaking science and technology development, unlocking the mysteries of our ocean, its connections to life on Earth, and solutions it may hold to some of our most pressing environmental challenges.

Our scientists and engineers lead more than 800 concurrent projects, tackling some of the most challenging and important problems of our time, from climate change and ocean pollution to sustainable food and energy production.

We operate a fleet of research vessels and vehicles, including two large ships (R/V Neil Armstrong and R/V Atlantis), a smaller coastal research vessel, the iconic human-occupied submersible Alvin, and dozens of other underwater robots.

Through our higher education programs, including the prestigious MIT-WHOI Joint Program, we train new generations of ocean scientists, engineers, and leaders-providing access to cutting edge facilities and unparalleled access to the sea.

WHOI plays a leading role in ocean communications, sharing our insights and knowledge about the ocean to the general public, policymakers, educators, and more, so we can make wise decisions about our ocean, our planet, and our future.


The ocean covers more than 2/3 of Earth's surface and is a fundamental reason why life exists on Earth-but yet many know so little about it. Dive in to learn more about our ocean planet.


For nearly a century, WHOI has been one of the best known and most trusted names in ocean science and exploration. Become a part of the research that shapes our understanding of the ocean, our planet, and life on Earth.
