‘Novel Ocean-Crust Mechanism Could Affect World’s Carbon Budget’

The Earth is constantly manufacturing new crust, spewing molten magma up along undersea ridges at the boundaries of tectonic plates. The process is critical to the planet’s metabolism, including the cycle of underwater life and the delicate balance of carbon in the ocean and atmosphere.

Now, scientists at the Woods Hole Oceanographic Institution (WHOI) have observed ocean crust forming in an entirely unexpected way—one that may influence those cycles of life and carbon and, in turn, affect the much-discussed future of the world’s climate.

Working at the Guaymas basin in the Gulf of California, WHOI scientists confirmed what they suspected from brief glimpses of the area during previous missions: The inner Earth is injecting swaths of magma called sills as far as 50 kilometers away from the plate boundary, on each side of the ridge —nearly 10 times farther from such an active ocean ridge than had been observed before.

Mysteries of Unpredictable Tsunami Waves

One of the most terrible consequences of offshore quakes is giant tsunami waves, sweeping everything on their way. Until now, scientists cannot answer a simple question: why in some cases they happen, and in others they do not? If it was established, then a tragedy like the one that has recently occurred in Indonesia could have been avoided.

An earthquake measuring 7.5 points, which occurred late on Monday, October 25 in Indonesia, caused a tsunami, which affected Mentawai islands in the western part of the country. Interestingly, the epicenter of the aftershocks of this earthquake was located 78 km west of the South Island Pagai of the Mentawai archipelago, at a depth of 20 km below the bottom of the Pacific Ocean. Apparently, this is why the first few minutes after the earthquake the Indonesian government reported the tsunami threat, but later canceled the alert. (more…)

Contrary to some previous, highly publicized, reports, ocean acidification is not likely to worsen the hearing of whales and other animals, according to a Woods Hole Oceanographic Institution (WHOI) scientist who studies sound propagation in the ocean. (more…)

Ocean’s Color Affects Hurricane Paths

WASHINGTON — A change in the color of ocean waters could have a drastic effect on the prevalence of hurricanes, new research indicates. In a simulation of such a change in one region of the North Pacific, the study finds that hurricane formation decreases by 70 percent. That would be a big drop for a region that accounts for more than half the world’s reported hurricane-force winds.

Do you remember the film ‘The French Connection’, a 1971 mafia sensation. A connection between New York and Marseilles (France). Two sides of Atlantic.

Now let’s start our story. We don’t need to cross the Ocean. 😉
