According to a 2013 study, marine species are pushing their range boundaries poleward, away from the Equator, at an average speed of 4.5 miles a year. That’s 10 times as faster as the speed at which species on land are moving.

Creating “Super Corals” for Warmer and Acidic Seas
by nicola jones In Hawaii this summer, as corals engage in their once-a-year courtship ritual of releasing sperm and eggs into the water by moonlight, Ruth Gates will oversee a unique mating: the coming together of “super-corals” in her lab…. Read More ›
Sea Change: A Scientific Conundrum and “The Blob”
Weird things are happening off the Pacific Coast.
And at the center of the action is a warm-water mass that scientists call “the blob.”
It’s turning the coastal ecosystem on its head. Species are dying along Washington, Oregon and northern California: sea stars, marine birds and sardines, among them.
Expect Changes at Your Fish Market
Seafood lovers are set to see less shellfish, salmon and other fish on their dinner plates as climate change warms the oceans and makes them more acidic. The findings from a series of studies out this week suggest rising greenhouse… Read More ›
The Trifecta of Ocean Hypoxia: Agriculture, Human Waste, Increased CO2
“When you can’t breathe, nothing else matters,” once a tagline of the American Lung Association, today it might easily describe what is happening in many areas of the ocean. Hypoxia, the lack of oxygen in our estuaries, coastal and deep… Read More ›
Studying a Changing Arctic Ocean
Changes in the Arctic Ocean are so profound that the region is entering what amounts to “a new era”, according to Norwegian scientists. A switch from a permanent cover of thick ice to a new state where thinner ice vanishes… Read More ›
Supercomputer Shows How Ocean Captures Carbon
The ocean sink for carbon won’t be able to keep up with what humans and nature are emitting. “Carbon emissions from fossil-fuel burning is far greater than capacity of oceans to take it up. We are sort of doubling the carbon in the atmosphere on a time scale of 100 years,” he said. “The carbon uptake into the ocean is on the scale of 1,000 years or 10,000 years.”

Researchers Debate Upwelling Variance by Climate Change
CORVALLIS, Ore. – A report to be published Thursday in the journal Nature suggests that global warming may increase upwelling in several ocean current systems around the world by the end of this century, especially at high latitudes, and will… Read More ›
Shellfish Production Vulnerable to Acidification
(Reuters) – U.S. shellfish producers in the Northeast and the Gulf of Mexico will be most vulnerable to an acidification of the oceans linked to climate change that makes it harder for clams and oysters to build shells, a study… Read More ›
Jellyfish Invasions Impact Industry
Nikkei Asian Review SHIGEHISA FURUYA, Nikkei staff writer TOKYO — Seas around the world are turning into jellyfish soup, as swarms of the creatures hit coastal areas, paralyzing power plants and undermining fisheries. These massive outbreaks are being caused by… Read More ›
