CO2 in the atmosphere heralds imminent food chain collapse — and it’s gonna start in the oceans

The first global analysis of how marine environments react to the ever-increasing levels of CO2 that humanity is pumping into the atmosphere does not bode well at all for tomorrow’s would-be fishers. Published today in the journal Proceedings of the National Academy of Sciences (PNAS), the work of the University of Adelaide’s marine ecologists states that the warming and expected ocean acidification is likely to produce a reduction in diversity and numbers of various key species that underpin marine ecosystems around the world.

Antarctic Ocean Sucks Down More and More Greenhouse Gases, But It’s Still Not Enough

The Antarctic Ocean has been sucking more and more carbon dioxide – and this is both good news and bad news. For the Ocean’s inhabitants, it’s bad news because it increases acidity, which is extremely harmful; for everyone else, it’s good news, because it mitigates the effects of climate change.

Greenland Glacier Loses Huge Chunk of Ice

Scientists have reported the break of a huge part of Jakobshavn Glacier, one of the largest ones in Greenland. A chunk of it roughly the size of Manhattan broke some time between August 13 and August 19.

Warming oceans could destroy corals in the Pacific and Atlantic, researchers warn

Coral populations are crucial to the health of oceanic environments, but corals are also extremely vulnerable to changing conditions. Researchers warn that warming waters and ocean acidification lead to coral bleaching which can cause massive damage across both the Atlantic and the Pacific.

Everything you should know about the Portuguese Man of War


The media seems to panic about recent Portuguese Man of War sightings along the Jersey shore in the US, without providing much information about the situation or this creature. Here, we’ll take a look at the Man of War and see what you should do to stay safe on the beach.

Ocean trek reveals the massive diversity of the oceanic plankton [with photos]


In what’s perhaps one of the most amazing marine science study, a team of researchers scoured the world’s oceans fishing for microbes, viruses and other tiny life during a three and a half year trip aboard a schooner. The trip was long and arduous for sure, but ultimately it paid out – big time! The team collected 35,000 samples at 210 stations over the voyage, and found 35,000 species of bacteria, 5,000 new viruses and 150,000 single-celled plants and creatures. Most of these are new to science. Only a small fraction of the newly discovered and known species alike had been genetically sequenced, but results so far show just how interconnected and symbiotic marine life is. It also means it’s also vulnerable in the face of environmental changes, particularly climate change.

NOAA to double size of California’s bay area marine sanctuary

The National Oceanic and Atmospheric Administration (NOAA), Obama administration and California lawmakers have announced a doubling of the size of the Cordell Bank and Gulf of the Farallones national marine sanctuaries off Northern California.   “NOAA is expanding the boundaries of Cordell Bank National Marine Sanctuary (CBNMS) and Gulf of the Farallones National Marine Sanctuary (GFNMS) to an area north and west

Arctic ice melting much faster than thought

On July 10, 2011, Don Perovich, of Cold Regions Research and Engineering Laboratory, maneuvered through melt ponds collecting optical data along the way to get a sense of the amount of sunlight reflected from sea ice and melt ponds in the Chukchi Sea.

Using both modern and historic measurements, researchers now have a more extensive view of how the Arctic sea ice has changed in the past few decades, finding that the ice is melting much faster than previously expected. The ice in the central Arctic Ocean thinned 65 percent between 1975 and 2012, from 11.7 feet (3.59 meters) to 4.1 feet (1.25 m).

This is what the underneath of an iceberg looks like


We often say that you only see 10% of the iceberg, the rest being underwater. US photographer Alex Cornell actually got the chance to see that – during a trip to Antarctica, he managed to take pictures of an extremely rare phenomenon: a flipped iceberg.

Obama proclaims world’s largest Marine Park


President Obama has signed a proclamation which will make the Pacific Remote Islands Marine National Monument the largest marine reserve in the world. Up until now, the Pacific Remote Islands Marine National Monument was a group of unorganized, mostly unincorporated United States Pacific Island territories managed by the Fish and Wildlife Service. They host many important species, including corals, fish, shellfish, marine mammals, seabirds,
