Identical Virus, Host Populations Can Prevail for Centuries, WHOI Researcher Reports

A Woods Hole Oceanographic Institution (WHOI) scientist, analyzing ancient plankton DNA signatures in sediments of the Black Sea, has found for the first time that the same genetic populations of a virus and its algal host can persist and coexist for centuries. The findings have implications for the ecological significance of viruses in shaping algae ecosystems in the ocean, and perhaps fresh water as well.

WHOI Study Sheds Light on Tunicate Evolution

Woods Hole Oceanographic Institution (WHOI) researchers have filled an important gap in the study of tunicate evolution by genetically sequencing 40 new specimens of thaliaceans, a gelatinous type of tunicate. Their study was featured on the cover of the June issue of the Journal of Plankton Research.

What Lives in the Sea?

The Census of Marine Life, a ten-year project to catalog all life in the sea, discovered more than 6,000 new species during its “decade of discovery,” scientists reported as they unveiled its results at a finale event in London Oct. 4-6. The collaboration combined the efforts of scientists from research organizations in more than 80 nations, including the Woods Hole Oceanographic Institution (WHOI).

The Salp: Nature's Near-Perfect Little Engine Just Got Better

What if trains, planes, and automobiles all were powered simply by the air through which they move? Moreover, what if their exhaust and byproducts helped the environment? Well, such an energy-efficient, self-propelling mechanism already exists in nature. The salp, a smallish, barrel-shaped organism that resembles a kind of streamlined jellyfish, gets everything it needs from the ocean waters to feed and propel itself. And, scientists believe its waste material may actually help remove carbon dioxide (CO2) from the upper ocean and the atmosphere.

Expedition to Mid-Cayman Rise Identifies Unusual Variety of Deep Sea Vents

The first expedition to search for deep-sea hydrothermal vents along the Mid-Cayman Rise has turned up three distinct types of hydrothermal venting, an interdisciplinary team led by Woods Hole Oceanographic Institution (WHOI) reports in this week’s Proceedings of the National Academy of Sciences. The work was conducted as part of a NASA-funded effort to search extreme environments for geologic, biologic, and chemical clues to the origins and evolution of life.

Sharks sniff out their prey, one nostril at a time

It turns out the old saying is right — the nose really does know. And when it comes to sharks, the nostrils are particularly discriminating. Combined with the ability to detect underwater vibrations, sharks are able to zero in on the location of their prey by smelling in stereo, according to a new study by researchers at the University of South Florida (USF) and Woods Hole Oceanographic Institution (WHOI).

Long-Distance Larvae Speed to New Undersea Vent Homes

Working in a rare, “natural seafloor laboratory” of hydrothermal vents that had just been rocked by a volcanic eruption, scientists from the Woods Hole Oceanographic Institution (WHOI) and other institutions have discovered what they believe is an undersea superhighway carrying tiny life forms unprecedented distances to inhabit the post-eruption site.

Newly Discovered Fat Molecule: An Undersea Killer with an Upside

A chemical culprit responsible for the rapid, mysterious death of phytoplankton in the North Atlantic Ocean has been found by collaborating scientists at Rutgers University and the Woods Hole Oceanographic Institution (WHOI).  This same chemical may hold unexpected promise in cancer research.

Mystery Solved: Marine Microbe Is Source of Rare Nutrient

A study newly published in Nature Geoscience has solved a ten-year-old mystery about the source of an essential nutrient in the ocean.

Rising acidity levels could trigger shellfish revenue declines, job losses

Changes in ocean chemistry — a consequence of increased carbon dioxide (CO2) emissions from human industrial activity — could cause U.S. shellfish revenues to drop significantly in the next 50 years, according to a new study by researchers at the Woods Hole Oceanographic Institution (WHOI).

Skip This Cocktail Party: Contaminants in Marine Mammals' Brains

The most extensive study of pollutants in marine mammals’ brains reveals that these animals are exposed to a hazardous cocktail of pesticides such as DDTs and PCBs, as well as emerging contaminants such as brominated flame retardants.

WHOI Team Aids Center for Coastal Studies in Whale Disentanglement

On Monday, May 4, a team of researchers from WHOI was working in the Great South Channel 40 miles east-southeast of Chatham, Mass., when they sighted a humpback whale severely entangled in fishing gear.  They alerted a rescue team from the Provincetown Center for Coastal Studies (PCCS) and kept watch over the humpback for three hours until the PCCS team could steam to the area to free the whale.

You Don't Call, You Don't Write: Connectivity in Marine Fish Populations

Children of baby boomers aren’t the only ones who have taken to setting up home far from where their parents live. A new study published this week in the Proceedings of the National Academy of Sciences documents how larval dispersal connects marine fish populations in a network of marine protected areas – information that is critical for fisheries managers.

Right whale sedation enables disentanglement effort

On Friday, March 6, 2009, for the first time ever, a North Atlantic right whale that had been severely entangled in fishing gear, was administered a sedation mixture that made it possible for rescuers to remove 90 percent of the entanglement.

Airborne pollutants can be toxic to marine algae

A newly published paper by ocean scientists shows that airborne particles off the continents can have deadly effect on some marine phytoplankton. The findings have implications for atmospheric carbon dioxide levels and climate.

Phytoplankton Cell Membranes Challenge Fundamentals of Biochemistry

Get ready to send the biology textbooks back to the printer. In a new paper published in Nature, Benjamin Van Mooy, a geochemist with the Woods Hole Oceanographic Institution (WHOI) and his colleagues report that microscopic plants growing in the Sargasso Sea have come up with a completely unexpected way of building their cells.

Emperor Penguins March toward Extinction?

Popularized by the 2005 movie “March of the Penguins,” emperor penguins could be headed toward extinction in at least part of their range before the end of the century, according to a paper by Woods Hole Oceanographic Institution (WHOI) researchers published January 26, 2009, in Proceedings of the National Academy of Sciences of the United States of America.

Bacterial Pathogens and Rising Temperatures Threaten Coral Health

Coral reefs around the world are in serious trouble from pollution, over-fishing, climate change and more. The last thing they need is an infection. But that’s exactly what yellow band disease (YBD) is—a bacterial infection that sickens coral colonies. Researchers at the Woods Hole Oceanographic Institution (WHOI) and colleagues have found that YBD seems to be getting worse with global warming and announced that they’ve identified the bacteria responsible for the disease.

Cold Water Corals Conference to be Held in Woods Hole

Scientists from North America and Europe will meet to develop the first coherent plan for studying and conserving cold-water corals in the Atlantic Ocean. The plan will lay the foundations for an international research program beginning 2010.

Study Reveals Microbes Dine on Thousands of Compounds in Oil

Thousands of feet below the bottom of the sea, off the shores of Santa Barbara, CA, single-celled organisms are busy feasting on oil. Until now, nobody knew how many oily compounds were being devoured by the microscopic creatures, but new research led by David Valentine of University of California at Santa Barbara (UCSB) and Chris Reddy of Woods Hole Oceanographic Institution (WHOI) in Massachusetts has shed new light on just how extensive their diet can be.
