Just off the coast of Peru, there's a huge amount of sea life. There are whales, a robust fishing industry, and a strange, gentle creature the size of a car called the giant manta ray.

It used to be that fat was fat, and fat was bad. Then, we learned about different kinds of fats – some worse for us than others – and then some other fats – the omega-3 fatty acids – that are actually good for us.

We are officially more than a month into hurricane season and we have a rare bit of good news: this year’s hurricane season may not be as active as originally thought, and it's already forecasted to be less active than last year.

Great white sharks have started filtering back into Massachusetts waters. Researchers are pretty sure food is what brings them here, but it’s hard to know for sure what sharks are thinking.

Three Cape Cod-based composers will mark World Oceans Day (Friday, June 8) by releasing a new album of original music developed in collaboration with ocean scientists. It’s called Black Inscription, and two of the composers – the husband and wife team Carla Kihlstedt and Matthias Bossi – spoke with Living Lab Radio about it.

In late 2015, the Colombian government announced they had found what could be the world’s most valuable shipwreck. The Spanish galleon ship San Jose sank off the Colombian coast in 1708 during a battle with British ships, and it is believed to hold billions of dollars worth of gold, silver, and emeralds. An underwater vehicle built and operated by Woods Hole Oceanographic Institution played a key role in the search, and now they’ve released new details of the search.
 

Hawaii has passed a ban on certain sunscreens that are harmful to corals.

Hawaii is poised become the first state to ban certain sunscreens – not because they are bad for people necessarily, but because they’ve been implicated in the decline of coral reefs. The ban specifically targets sunscreens that contain two chemicals – oxybenzone and octinoxate. The bill is awaiting the governor’s signature.

Many long-time Cape Codders would be surprised to learn that there is coral growing along Cape Cod’s shores – no big reefs, just hearty chunks of coral that can survive water temperatures close to freezing.

A fossil found in Kansas seventy years ago has been identified as a large cartilaginous fish, like a shark or a ray. That wouldn’t be so noteworthy if the same fossil hadn’t already been identified, twice – first as a green alga, and then as a squid or cuttlefish.

Japanese scientists announced this past week that they had not only discovered bacteria that naturally digest the PET plastic used to make many water bottles, they had also genetically modified them to make them better at breaking down plastic. Headlines made it seem like our plastic pollution woes were over.

The twilight zone. It’s not just a spooky 1960s television series. It’s what scientists call the part of the ocean between about 600 and 3000 feet below the surface. It’s deep, it’s dark (thus, the name), and it’s relatively unstudied. But it may be home to more life than the rest of the ocean, combined, and also key to the ocean’s ability to suck carbon dioxide out of the atmosphere.

The ocean has a plastic problem. And it’s growing. Several million tons of plastic enter the ocean every year, and much of it ends up swirling around in the middle of ocean basins.

A workshop in Woods Hole on February 1st brought together an unusual combination of scientists, engineers, fishermen, and government regulators to talk about an even more unusual idea: catching lobsters with no rope connecting the traps at the bottom with a buoy at the surface.

It’s no secret that the lobster fishery in southern New England is in trouble. The population has declined by almost eighty percent in the past few decades. In contrast, lobsters in the Gulf of Maine have exploded and the fishery has seen record landings. So, what gives?

You probably knew that whales make sounds to communicate. But did you know that fish are chatting down there, too? It turns out that fish vocalize to find mates, and ship noise may be interfering. A new study looked at haddock and cod, two commercially important fish species, to find out more about how fish are managing in an increasingly noisy ocean. We talk to researcher Jenni Stanley of Northeast Fisheries Science Center at NOAA in Woods Hole.
