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?
White shark tagging expedition sets sail (July 31), Discovery Channel Shark Week segment "The Return of Jaws" features WHOI's REMUS technology (Aug. 5), and WHOI scientists and engineers share latest research at Woods Hole public event (Aug. 7)
Corals may let certain bacteria get under its skin, according to a new study by researchers at WHOI and King Abdullah University of Science and Technology (KAUST) and published in the journal Applied and Environmental Microbiology. The study offers the first direct evidence that Stylophora pistillata, a species of reef-building coral found throughout the Indian and west Pacific Oceans, harbors bacterial denizens deep within its tissues.
Acidifying oceans could dramatically impact the world’s squid species, and because squid are both ecologically and commercially important, that impact may have far-reaching effects on the ocean environment and coastal economies, the researchers report.
The widespread disappearance of stromatolites, the earliest visible manifestation of life on Earth, may have been driven by single-celled organisms called foraminifera, study finds.
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.
A group of oceanographic experts is calling for the establishment of a national network to monitor the diversity of marine life, a key bellwether of ocean and human health. Their work is described in the April 11 issue of BioScience.
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.
There are more microbes in a bucket of seawater than there are people on Earth. Despite their abundance, humans are only just beginning to fathom the complex role marine microbes play in the ocean ecosystem.
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.
Japan fisheries data provides insight into the fate and impacts of radionuclides from Fukushima 18 months after the worst accidental release of radiation to the ocean in history.
The ability of deep-sea corals to harbor a broad array of marine life, including commercially important fish species, make these habitat-forming organisms of immediate interest to conservationists, managers, and scientists. Understanding and protecting corals requires knowledge of the historical processes that have shaped their biodiversity and biogeography.
Ocean scientists have long known that juvenile coral reef fishes use coastal seagrass and mangrove habitats as nurseries, later moving as adults onto coral reefs. But the fishes’ movements, and the connections between different tropical habitats, are much more complex than previously realized, according to a study published September 3 in Proceedings of the National Academy of Sciences. The findings have important implications for management and protection of coral reefs and other marine environments.
Scientists from the WHOI, University of Washington, and University of Maine are combining models with data from a flotilla of high-tech robots to shed new light on life-sustaining phytoplankton, including when their spring bloom begins and the role that small-scale eddies play in promoting their growth.
At nearly four feet tall, the Emperor penguin is Antarctica’s largest sea bird—and thanks to films like “March of the Penguins” and “Happy Feet,” it’s also one of the continent’s most iconic. If global temperatures continue to rise, however, the Emperor penguins in Terre Adélie, in East Antarctica may eventually disappear, according to a new study by led by researchers from the Woods Hole Oceanographic Institution (WHOI). The study was published in the June 20th edition of the journal Global Change Biology.
A team of researchers, including scientists from the Woods Hole Oceanographic Institution (WHOI), discovered a massive bloom of phytoplankton beneath ice-covered Arctic waters. Until now, sea ice was thought to block sunlight and limit the growth of microscopic marine plants living under the ice.
Studying algal cultures and seawater samples from the Southern Ocean off Antarctica, a team of researchers from Woods Hole Oceanographic Institution and the J. Craig Venter Institute have revealed a key cog in the biochemical machinery that allows marine algae at the base of the oceanic food chain to thrive. They have discovered a previously unknown protein in algae that grabs an essential but scarce nutrient out of seawater, vitamin B12.
Scientists have predicted that ocean temperatures will rise in the equatorial Pacific by the end of the century, wreaking havoc on coral reef ecosystems. But a new study by WHOI scientists shows that climate change could cause ocean currents to operate in a surprising way and mitigate the warming near a handful of islands right on the equator. As a result these Pacific islands may become isolated refuges for corals and fish.
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.
