Just like with humans, the skin on marine mammals serves as an important line of defense against pathogens in their environment. A new study sheds light on the skin microbiome—a group of microorganisms that live on skin—in healthy humpback whales, which could aid in future efforts to monitor their health.
A new study by the Woods Hole Oceanographic Institution (WHOI) and colleagues identified for the first time an extensive conserved group of bacteria within healthy humpback whales' blow—the moist breath that whales spray out of their blowholes when they exhale.
Scientists working for WCS’s (Wildlife Conservation Society) New York Aquarium and the Woods Hole Oceanographic Institution (WHOI) now have an "ear" for the New York region’s biggest "voices and singers"— the whales of New York Bight.
Amy Apprill, a microbiologist at the Woods Hole Oceanographic Institution (WHOI), is one of the extraordinary women scientists featured in Science Magazine's online video series, "XX Files: Extraordinary Science, Extraordinary Women."
A research team studying entangled North Atlantic Right Whales has for the first time quantified the amount of drag created by towed fishing gear.
An international team of biologists has made the first-ever field observations of one of the least known species of whales in the world—Omura's whales—off the coast of Madagascar.
A research team has successfully demonstrated a new non-invasive tool to obtain hard-to-get health measurements of large endangered whales in the wild.
How well do marine mammals hear in the wild? WHOI biologist Aran Mooney and his colleagues are the first to publish a study of hearing in a population of wild marine mammals.
Researchers at Woods Hole Oceanographic Institution (WHOI) and colleagues identified a core skin bacterial community that humpback whales share across populations, which could point to a way to assess the overall health of these endangered marine mammals.
While countries such as Japan, Norway, and Iceland often are criticized for their commercial whaling practices, Woods Hole Oceanographic Institution (WHOI) marine biologist Michael Moore points out how the majority of nations are also complicit in killing whales by deploying commercial fishing gear.
For scientists studying marine mammals in the wild, data-logging tags are invaluable tools that allow them to observe animals’ movements and behaviors that are otherwise hidden beneath the waves much of the time. The tags, which temporarily attach to animals using suction, record sounds and gather information about animals’ pitch, speed, and depth. But what effect do the tags have on the animals?
Using a “patient monitoring” device attached to a whale entangled in fishing gear, scientists showed for the first time how fishing lines changed a whale’s diving and swimming behavior. The monitoring revealed how fishing gear hinders whales’ ability to eat and migrate, depletes their energy as they drag gear for months or years, and can result in a slow death.
Two robots equipped with instruments designed to “listen” for the calls of baleen whales detected nine endangered North Atlantic right whales in the Gulf of Maine last month. The robots reported the detections to shore-based researchers within hours of hearing the whales (i.e., in real time), demonstrating a new and powerful tool for managing interactions between whales and human activities.
An analysis by WHOI biologist Rebecca Gast examines water quality data to determine whether a growing population of gray seals along Cape Cod beaches can be blamed for beach closures.
New Research Consortium Brings Scientists, Fishermen, and Managers Together to Address Seal Issues in the Northeast
People come from miles away to see the seals off the shores of Cape Cod and surrounding regions, but the animals are creating some challenges for local fishermen. Recent increases in local seal abundance have led to concerns about fisheries interactions. The urgency of documenting, understanding, and mitigating these interactions has become more apparent.
For decades, scientists have known that dolphins and other toothed whales have specialized fats associated with their jaws, which efficiently convey sound waves from the ocean to their ears. But until now, the hearing systems of their toothless grazing cousins, baleen whales, remained a mystery, largely because specimens to study are hard to get. Now, a new study by scientists at Woods Hole Oceanographic Institution has shown that some baleen whales also have fats leading to their ears.
In a study published online in the Proceedings of the Royal Society B, a team that includes researchers from the Woods Hole Oceanographic Institution (WHOI) has confirmed that bubbles do form in live, stranded dolphins. But in many cases, those animals are able to “manage” those bubbles and can resume relatively normal lives of swimming and diving in the ocean.
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.
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.
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.
