By visiting the final resting place of the Portland, researchers will document changes that have occurred at the site of the wreck and gain more insight into the fate of the doomed steamer.The expedition is being led by NOAA’s Office of National Marine Sanctuaries, the Woods Hole Oceanographic Institution, and Marine Imaging Technologies.
“As the Arctic’s atmosphere is heating up it is reducing the gradient, and that slows down the jet stream,” says Glen Gawarkiewicz, an oceanographer at the Woods Hole Oceanographic Institution who helped track the phenomenon. “It’s been having these big meanders and sometimes just gets stuck in one position for weeks at a time.”
A new report from Woods Hole Oceanographic Institution (WHOI) discusses some of the science of sea level rise and highlights three key processes that contribute to the phenomenon. Produced in conjunction with climate science expert Dr. Christopher Piecuch, the report also describes some of the research being conducted to better understand how and why sea levels are rising, so that we can more confidently predict future changes.
BBC radio host Rhod Sharp and Jeff Donnelly of WHOI’s Coastal Research Lab trace the history of hurricanes in the Atlantic and discuss the frequency of intense storms. New sediment records indicate that historically unprecedented levels of intense hurricane activity impacted the eastern seaboard of the United States and northeastern Gulf Coast in the last two millennia.

Rainfall forecasting is big money! For over 40 years, Ray Schmitt has been a physical oceanographer at Woods Hole Oceanographic Institution.
On 27 November 2015, the San José was “officially” discovered by a robotic submarine called the REMUS 6000, which is operated by the US-based Woods Hole Oceanographic Institution.
According to the Woods Hole Oceanographic Institution website, diarrhetic shellfish poisoning produces gastrointestinal symptoms, usually beginning within 30 minutes to a few hours after consumption of toxic shellfish. Although not fatal, the illness is characterized by incapacitating diarrhea, nausea, vomiting and abdominal pain.
“The most striking thing is just how far down it is and how the light dissolves away,” says Joel Llopiz, a biologist with Woods Hole Oceanographic.
Lava-driven nutrient fountains “could be a pretty important driver of phytoplankton ecology in the broader ocean,” said Harriet Alexander, a biological oceanographer at the Woods Hole Oceanographic Institution who was not involved in the latest study.
When asked what remains mysterious about them, Simon Thorrold, a senior scientist at the Woods Hole Oceanographic Institution laughs, explaining: “It will be way quicker to go over what we do know. And that is almost nothing.”
Where are the sources of these microplastics? Well, as a Woods Hole Oceanographic Institution video explains, some of the microplastics may be coming from larger plastic objects such as bottles and other households goods being ground up by the elements.
The twilight zone can be found 200 to 1,000 meters (about 650 to 3,300 feet) below the ocean surface, at the point where the sun’s rays can no longer reach, according to the Woods Hole Oceanographic Institute (WHOI) in Massachusetts. Because it’s so deep and there’s no sunlight, it’s cold and dark.
“This region, the Scotia Sea, is unique in that it hosts several different physical mechanisms which launder dense water to make it lighter within a relatively small basin (the Southern Scotia Sea),” says co-author Dr. Kurt Polzin of WHOI. “This small basin relative to a relatively large volume transport enables researchers to assess changes in water mass production ultimately coming from the Antarctic Shelves on a biennial basis, compared to decadal time scales from other sections.”
This year, the fourth for the program, EarthWatch kept the program local, teaming up with Sea Grant at Woods Hole Oceanographic Institution (WHOI) to provide girls in Massachusetts with experiences in all types of sciences, Woodroof said. Only girls from Massachusetts were selected, which included a couple from the Cape and a couple with seasonal ties to the Island.
After several years, Kara Dodge began to do other work with turtles, in particular a “TurtleCam” project with Woods Hole Oceanographic Institution engineer Amy Kukulya. The project involved tagging and tailing turtles with autonomous underwater vehicles to study diving behavior, eating habits, and assess ways to reduce entanglements.
Scientists from the Benioff Ocean Initiative and Woods Hole Oceanographic Institution have deployed a a hydrophone, or underwater microphone, to listen for whale traffic in the Santa Barbara Channel. They hope to use the microphone to help prevent collisions between whales and boats – which are often deadly to whales.
As part of a partnership with the Woods Hole Oceanographic Institution, guests aboard The Whale Science Voyage, one of their annual itineraries (February 27- March 11, 2020), can participate in a major research study being conducted by a team of scientists on climate change and its impact on the humpback whale population, an animal that is protected under the Endangered Species Act.
“When hydrothermal vents were discovered in 1977, it very much flipped biology on its end,” says Julie Huber, an oceanographer who studies life in and below the seafloor at Woods Hole Oceanographic Institution (WHOI) on Cape Cod. “People knew that organisms could live off of chemical energy, but they didn’t imagine they could support animal ecosystems.”
Scientists know methane is released from deep-sea vents, but its source has long been a mystery. A team from Woods Hole Oceanographic Institution may have the answer. Analysis of 160 rock samples from across the world’s oceans provides evidence, they say, of the formation and abundance of abiotic methane – methane formed by chemical reactions that don’t involve organic matter.
“Identifying an abiotic source of deep-sea methane has been a problem that we’ve been wrestling with for many years,” says marine geochemist Jeffrey Seewald from the Woods Hole Oceanographic Institution (WHOI).”Here’s a source of chemical energy that’s being created by geology.”
Woods Hole Oceanographic Institution has begun the permit process for a $27 million, 50,000-square-foot building planned for its Quissett campus.
Bernhard Peucker-Ehrenbrink, a geochemist at Woods Hole Oceanographic Institution, who was not involved in the study, praised the team’s work for detecting substantial amounts of iron-60, originating from outside the solar system.
Michael Moore, a scientist at the Woods Hole Oceanographic Institution, raised the concern that the “torturous” process the fisheries service was undertaking to write and enact the new regulations would “still come up short.”
The editors of Marine Technology Reporter are pleased to share that Dr. Mark Abbott, President & Director, Woods Hole Oceanographic Institution (WHOI), is #5 in the 14th Annual “MTR100”.
