Sea pickles are adapting to the Pacific Northwest

Fri, 20 Jul 2018 09:25:09 EDT ~ Tubular colonial jellies known as pyrosomes that arrived in 2014 along North America's Pacific Northwest Coast appear to be adapting to cooler water and may become permanent residents. Find out more...

Deep-diving scientists say shallow reefs can't rely on twilight zone systems for recovery

Thu, 19 Jul 2018 14:21:33 EDT ~ A team of highly trained scientific divers explored Pacific and western Atlantic reefs to test a widely held hypothesis that climate-stressed life from shallow reefs can take refuge at mesophotic depths (100-500 feet beneath the ocean's surface). The results are clear: deep and shallow reefs are different systems with their own species, and deep reefs are just as threatened by climate impacts, storms, and pollution. Find out more...

In a warming climate, Arctic geese are rushing north

Thu, 19 Jul 2018 14:21:15 EDT ~ As Arctic temperatures continue to rise, migratory barnacle geese have responded by speeding up their 3,000-kilometer migration in order to reach their destination more quickly with fewer stops along the way, according to new evidence. Unfortunately, the birds' earlier arrival isn't making as much of a difference as one might expect. Find out more...

In the ocean's twilight zone, tiny organisms may have giant effect on Earth's carbon cycle

Wed, 18 Jul 2018 17:03:08 EDT ~ In a new study that challenges scientists' presuppositions about the carbon cycle, researchers find that tiny organisms may be playing in outside role in the way carbon is circulated throughout the ocean. Find out more...

Great Barrier Reef not bouncing back as before, but there is hope

Wed, 18 Jul 2018 14:31:09 EDT ~ The Great Barrier Reef is losing its ability to recover from disturbances, but effective local management could revive its capacity to bounce back. Find out more...

Glowing bacteria on deep-sea fish shed light on evolution, 'third type' of symbiosis

Wed, 18 Jul 2018 14:30:50 EDT ~ For the first time, scientists have sequenced and analyzed the genomes of bacteria that live in anglerfish bulbs. The bacteria were taken from fish specimens collected in the Gulf of Mexico. Find out more...

Origami-inspired device helps marine biologists study octopuses and jellyfish

Wed, 18 Jul 2018 14:30:45 EDT ~ Scientists have tried to find the safest and most effective ways to explore marine life in the oceanic water, the largest and least explored environment on Earth, for years. Each time, they were faced with the same challenge: How to capture delicate or gelatinous pelagic animals -- like jellyfish, squid, and octopuses -- without harming them? An origami-inspired device may change that. Find out more...

Where baby white sharks 'hang out' in the North Atlantic

Wed, 18 Jul 2018 13:11:12 EDT ~ A team of scientists is the first to confirm the movement patterns and seasonal migrations of baby white sharks in the north Atlantic Ocean. They put the New York Bight shark nursery theory to test by deploying satellite and acoustic tags on 10 baby white sharks (less than 1 year old) off Long Island's coast. Results provide novel insights into the distribution of this vulnerable early stage of life that complements recent work on larger white sharks. Find out more...

Global study of world's beaches shows threat to protected areas

Wed, 18 Jul 2018 11:33:46 EDT ~ A first-of-its-kind survey of the world's sandy shorelines with satellite data found that they have increased slightly on a global scale over the past three decades but decreased in protected marine areas, where many beaches are eroding. Find out more...

Novel approach studies whale shark ages the best way -- while they are swimming

Wed, 18 Jul 2018 10:47:34 EDT ~ A new study of whale sharks, using a novel approach to gathering data, shows these endangered animals can live longer and grow larger than previously believed. Find out more...
