The Coastal Ocean Institute
We are all stewards of the coastal ocean. For some of us, the connection to the sea is clear and immediate; for others, it is subtle and distant. But whether you live on waterfront property or in a land-locked hamlet, your everyday activities affect this most sensitive and most threatened portion of the world?s oceans.
Do Marine Protected Areas Really Work?
Today, Marine Protected Areas, or MPAs—areas of the ocean temporarily or permanently closed to harvesting—are being proposed to restrict not only fishing, but also mineral and hydrocarbon extraction, and other activities. Some advocates of MPAs suggest that at least 20 percent of the coastal and open ocean should be set aside and permanently zoned to protect ecosystems, sustain fish stocks, and reduce conflicts between users of the oceans.
Robo-Sailors
In the mid-1990s, the Navy began funding research for small, robotic vehicles to perform unmanned reconnaissance in coastal waters. At WHOI, that helped spark the development of REMUS (Remote Environmental Monitoring UnitS), designed and built by Chris von Alt, Ben Allen, and colleagues in the Oceanographic Systems Laboratory.
The Cacophony on the Coast
Unlike light, sound travels efficiently through water, and the Navy uses sound to monitor what’s going on in the ocean. To understand the sound messages transmitted through the seas, you need to understand the medium through which they are transmitted.
New Instrument Sheds Light on Bioluminescence
Bioluminescence is ubiquitous in the oceans, and especially prevalent in coastal regions where nutrients are abundant and life thrives. Yet scientists have little basic understanding of how bioluminescence is influenced by water temperatures, depths, seasons, geographic locations, even different times of day.
For the Navy, the Coast Isn’t Clear
Every so often, circumstances can conspire to make a battleship turn on a dime. Fifteen years ago, two geopolitical events prompted the U.S. Navy to abruptly change long-standing research priorities and steer rapidly in a new direction.
Where Are Mines Hiding on the Seafloor?
Eternally and incessantly, waves and currents stir up sand from the seafloor near the coast. Sediments get suspended in the ocean, carried onshore and off, and deposited elsewhere. In the process, objects on the seafloor—natural and unnatural—can get buried and uncovered.
Can We Catch More Fish and Still Preserve the Stock?
People have always fished. But the history of fishing is also the history of overfishing. For hundreds of years, the establishment and enforcement of fishery management policies have generated controversy, as competing authorities have searched for a way to balance competing goals—to catch as many fish as possible while conserving the resource. To resolve this dilemma, we have applied mathematics—and we are finding that the ancient solution may still prove effective in modern times.
A Fatal Attraction for Harmful Algae
Estuaries are the borderlands between salt and freshwater environments, and they are incredibly diverse
both biologically and physically. The diversity and the high
energy of the ecosystem make estuaries remarkably resilient.
With a better understanding of these systems, we can reverse
their decline and restore the ecological richness of these
valuable, albeit muddy, environments.
Rites of Passage for Juvenile Marine Life
The childhood of a barnacle is fraught with challenges. It hatches in shallow waters close to shore as a tiny larva, no bigger than a speck of dust. Currents sweep it to deeper, choppy waters, sometimes miles offshore. In these proving grounds each larva floats, at the mercy of hungry fish and swift ocean currents. Billions of larvae?including fish, lobsters, clams, starfish, and sea cucumbers?begin life this way. Only a few survive and return to shore, where they settle on rocks or sandy seafloor to become adults. Why larvae make their offshore journey remains unclear, but we are beginning to uncover the intricacies of their return trip?learning how waves, currents, eddies, tides, and other phenomena bring larvae back toward the shore.
The New Wave of Coastal Ocean Observing
Estuaries are the borderlands between salt and freshwater environments, and they are incredibly diverse both biologically and physically. The diversity and the high energy of the ecosystem make estuaries remarkably resilient. With a better understanding of these systems, we can reverse
their decline and restore the ecological richness of these valuable, albeit muddy, environments.
Red Tides and Dead Zones
The most widespread, chronic environmental problem in the coastal ocean is caused by an excess of chemical nutrients. Over the past century, a wide range of human activities—the intensification of agriculture, waste disposal, coastal development, and fossil fuel use—has substantially increased the discharge of nitrogen, phosphorus, and other nutrients into the environment. These nutrients are moved around by streams, rivers, groundwater, sewage outfalls, and the atmosphere and eventually end up in the ocean.
