Exploring the Undiscovered Country: The Deep Ocean
Special equipment is required to visit these extreme depths, which is why less than 5% of this area has been explored and charted.
‘The concept looks fairly solid.’ Researchers test new clay process to kill red tide cells
The process, known as clay flocculation, involves spraying a mixture of clay particles and seawater onto the red tide algae.
‘Rolls-Royce’ of shark cameras can extend to turtles, whales, seals and squid for ocean’s big picture
A high-tech SharkCam invented by a Cape Cod researcher offers an unprecedented window into the lives of the ocean’s toothy predators, and can also extend to seals, whales, turtles and squid for a big-picture view of precious ecosystems and how to protect them. “These vehicles, these underwater robots that look like highly complex systems are just an extension of yourself to be able go where people can’t go, and there’s no limitation to what they can do,” said Amy Kukulya, research engineer and principal investigator at Woods Hole Oceanographic Institution.
Melting ice imperils 98% of Emperor penguin colonies by 2100
WASHINGTON (AP) — With climate change threatening the sea ice habitat of Emperor penguins, the U.S. Fish and Wildlife Service on Tuesday announced a proposal to list the species as threatened under the Endangered Species Act. “The lifecycle of Emperor penguins is tied to having stable sea ice, which they need to breed, to feed and to molt,” said Stephanie Jenouvrier, a penguin ecologist at the Woods Hole Oceanographic Institution.
What Happens to Marine Life When There Isn’t Enough Oxygen?
In September of 2017, Woods Hole Oceanographic Institution postdoctoral scholar Maggie Johnson was conducting an experiment with a colleague in Bocas del Toro off the Caribbean coast of Panama. After sitting on a quiet, warm open ocean, they snorkeled down to find a peculiar layer of murky, foul-smelling water about 10 feet below the surface, with brittle stars and sea urchins, which are usually in hiding, perching on the tops of coral. This unique observation prompted a collaborative study explained in a new paper published on July 26, 2021, in Nature Communications analyzing what this foggy water layer is caused by, and the impact it has on life at the bottom of the seafloor.
Loss of Oxygen in Oceans Detrimental to Marine Life; Scientists Show How Deoxygenation Rapidly Affects Reef Ecosystem
According to Phys.org, Johnson and her team snorkeled down the water, and there they found the peculiar layer of water that has brittle stars and sea urchins, which are uncharacteristically perching on the top of coral reefs as they are usually hiding.
Impact of Hypoxic Ocean Waters on Marine Life
Investigators suggest that loss of oxygen in the global ocean is accelerating due to climate change and excess nutrients, but how sudden deoxygenation events affect tropical marine ecosystems is poorly understood.
A dragnet for toxic algae?
To keep a close eye on harmful algal blooms, shellfish farmers are relying on a WHOI-developed camera system that spies on toxic species below the surface and sends alerts when…

“Expeditions like these teach us why we need to increase our efforts to restore and better understand marine ecosystems everywhere — because the great chain of life that begins in the ocean is critical for human health and well being,” Schmidt said.
