Shark Tales
Sharks are some of the largest fish in the ocean, but their movements and behavior have remained largely hidden from people.

Expeditions to the tropics and Antarctica have turned up crab populations—for better or worse—in unexpected parts of the globe. At the Hannibal Bank Seamount, an 1,180-foot-high undersea mountain off Panana’s…

For more than a decade, researchers have been tagging large marine mammals such as dolphins and whales to reveal their behavior. But tagging small, soft animals such as jellyfish and…

Imagine that officials charged with setting deer-hunting limits had to assess the herd’s abundance by flying over forests at night. That’s a little like what the National Marine Fisheries Services…

Scientists have discovered a thriving population of Omura’s whales—a species that hadn’t even been identified until 2003 and had never before been documented in the wild. Omura’s whales were misidentified…

That’s exactly what a team of researchers from Woods Hole Oceanographic Institution (WHOI) did on a recent expedition to the Danger Islands off the Antarctic Peninsula. The islands are home…
Read MoreEndangered Whales Get a High-Tech Check-Up
Drones seem to be everywhere these days, from backyards to battlegrounds. Scientists are using them too: in this case, to assess the health of endangered North Atlantic right whales. Since drones are small and quiet, they can fly close to whales without disturbing them, bringing back incredibly detailed photographs and samples of microbe-rich blow.

Bacteria in the ocean, including pathogenic ones, often hitchhike on tiny crustaceans called copepods. A graduate student explored their complex relationships.

MIT-WHOI graduate student Megan May is investigating how microbes naturally develop resistance to antibiotic compounds in the marine environment and how human activities, including overuse of drugs and pollution, may be affecting the dynamic.

Over his long career at WHOI, Bill Watkins pioneered new instruments to collect sounds of whales, dolphins, and other marine mammals. That treasure trove will now be archive in the…
Read MoreNew AUV Plankton Sampling System Deployed
Traditionally, pumps and nets are used for sampling plankton, which require sampling at predetermined stations or towing nets behind a ship, followed by visually sorting collected organisms into taxonomic groups. Samples generally combine organisms collected throughout horizontal or vertical tracks, making it impossible to detect small gradations or species-specific patterns in larval distribution.
The sampling system combines three cutting edge technologies—an adapted Suspended Particulate Rosette (SUPR) multi-sampler, a REMUS autonomous underwater vehicle equipped with sensors, and identification of organisms by DNA barcode analysis. They’ve dubbed the new system “SUPR-REMUS.”
Read MoreUltrasounds for Coral Reefs?
In a study, published Aug. 6, 2015 in Marine Ecology Progress Series, scientists at Woods Hole Oceanographic Institution (WHOI) used low-cost autonomous underwater recorders over four months to collect “soundscapes” of reefs in in the U.S. Virgin Islands. They showed how the collective sound recordings of reef inhabitants painted vivid pictures of the reefs’ abundance and diversity.
In a second study, published the same day in Marine Pollution Bulletin, the researchers recorded boat noise—showing how it could mask vital sounds that organisms make to reproduce, feed, and find new homes. They also demonstrated how underwater recorders could help marine managers keep an ear on potentially disruptive human activity in far-off locations.
Read MoreWhale Research Takes Flight
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: Using a small remote-controlled hexacopter, scientists for the first time collected both breath samples from the whales’ spouts combined with aerial photos of their body condition.
Read MoreCamera’s Eye Sees Large Numbers of Young Scallops Off Delaware Bay
NOAA researchers and colleagues from the Woods Hole Oceanographic Institution (WHOI) have reported what appears to be a banner year for young sea scallops off the Delmarva Peninsula in mid-Atlantic waters of the U.S. NOAA’s HabCamV4, a towed imaging and sensor platform, has photographed miles of sea bottom packed with as many as 350 sea scallops in less than 1 square meter (less than three square feet). Other colorful images captured by the HabCam showed swimming scallops, sea stars and crabs—both scallop predators—and many species of fish, squid and sponges.

Read MoreGulf of Maine Red Tide Bloom Expected to Be Similar to Past Three Years
New England’s spring and summer red tides will be similar in extent to those of the past three years, according to the 2015 Gulf of Maine red tide seasonal forecast. The forecast is the eighth seasonal Gulf of Maine red tide forecast funded by NOAA and issued by scientists from the Woods Hole Oceanographic Institution and North Carolina State University.
The forecast is part of a larger NOAA effort to deliver ecological forecasts that support human health and well-being, coastal economies, and coastal and marine stewardship.
Red tide, a type of harmful algal bloom (HAB) caused by the alga Alexandrium fundyense, produces a toxin that can lead to paralytic shellfish poisoning, which can result in serious or even fatal illness in humans who eat contaminated shellfish. In 2005, an unusually large red tide event caused $23 million in lost shellfish sales in Massachusetts and Maine.
