One patch of water in the center of the Pacific Ocean has remained virtually motionless for the past 1,000 years. Now, a recent study published online in Nature has uncovered some of the secrets of this mysterious "shadow zone," revealing not only why it has remained still for so long, but also what the ocean looked like a millennium ago.
In October last year, a fishing boat set out from Velddrif, a small town on South Africa’s west coast. It sailed northwest for about 25 nautical miles (46 kilometres), then turned sharply and headed back the way it had come. Staying clear of coastal settlements, it entered the West Coast National Park marine protected area — a strictly no-fishing zone — where it slowed down and began to sail in a zigzag pattern. “It was obvious what they were doing,” says Niel Malan, a marine biologist who works in South Africa’s Department of Environmental Affairs in Cape Town. “They were poaching.”
Antarctica is getting a little hot under the collar. Just under the frozen wasteland of the world's coldest continent are some seriously hot rocks, which are helping to melt its ice sheet and create lakes and rivers, a study found.
A new paper published in Nature Communications serves as an excellent reminder of the long-term value of ocean research and data collection. This paper provides the first holistic analysis of the Ocean Biogeographic Information System (OBIS), which is a legacy of the Census of Marine Life – a global initiative that COL managed for a [...]
It looks like a baby manta ray flapping its wings as it glides through the water. But it’s actually an aquatic robot which swims at a speed of twice its body length per second and can operate for up to 10 hours. Meet the MantaDroid.
Coral reefs, seagrass meadows and mangrove forests work together to make the Coral Triangle of Indonesia a hotspot for marine biodiversity. The system supports valuable fisheries and endangered species and helps protect shorelines. But it is in global decline due to threats from coastal development, destructive fishing practices and climate change.
You’re camping in the woods, about to tuck into some salmon you’ve caught when a bear appears. It’s waiting for you to eat your fish, so it can swoop in to eat you. This is a steal for the bear. For the price of a human, it’s bagged a human-salmon combo meal.
Canadian and US Department of Energy researchers have released 50 years' worth of data chronicling the deoxygenating cycles of a fjord off Canada's west coast, and detailing the response of the microbial communities inhabiting the fjord.

And the effects may only worsen with future climate change. (From Scientific American / by [...]
Colorless, odorless, and potentially lethal, carbon monoxide is so feared by people that we have special monitors in our homes to detect it. But its accumulation in the blood helps elephant seals make deep dives in the ocean, researchers reported here last week at the biennial meeting of the Marine Mammal Society. Aside from helping explain how elephant seals can stay so deep for so long, the work could one day help people recover from traumatic events like heart attacks and organ transplants.
