This Armada of Saildrones Could Conquer the Ocean

The Robots Roaming the High Seas

Engineer and adventurer Richard Jenkins has made oceangoing robots that could revolutionize fishing, drilling, and environmental science. His aim: a thousand of them.

Every spring, thousands of great white sharks begin a mysterious migration. From up and down America’s West Coast, they head straight for a Colorado-size patch of the Pacific about halfway between San Diego and Hawaii. Once there, they hang for months at what marine biologists call the White Shark Cafe, frolicking and diving 1,500 feet or more. For decades, we didn’t know much more about what they do there—or why. This year, we should get some answers, thanks to a pair of saildrones.

Busy Microbial World Discovered in Deepest Ocean Crust Ever Explored

microbial life interactions going on in the deepest ocean crust ever explored!

The first study to ever explore biological activity in the deepest layer of ocean crust has found bacteria with a remarkable range of capabilities, including eating hydrocarbons and natural gas, and “fixing” or storing carbon.

Reverse Circulation in Atlantic Ocean

this wil make your toilet spin the other direction upon a flush. Fear not.

Universitat Autònoma de Barcelona scientists have researched how ocean currents in the Atlantic were affected by climate change in the past. The study shows that there was a period when the flow of deep waters in the Atlantic was reversed. The results are relevant for the near future since similar changes are expected to occur in the course of climate warming over the next 100 years.

Tides, Earth’s Rotation Among Sources of Giant Underwater Waves

Scientists are gaining new insight into the mechanisms that generate huge, steep underwater waves that occur between layers of warm and cold water in coastal regions of the world’s oceans.

Scientists at the University of Rhode Island are gaining new insight into the mechanisms that generate huge, steep underwater waves that occur between layers of warm and cold water in coastal regions of the world’s oceans.

Hydrothermal Vents Discovered Off Antarctica

100303114012

A vent spews chemical fluids from the East Pacific Rise, about 5,600 miles from newly suspected vents on the Pacific Antarctic Ridge.

Scientists at Columbia’s Lamont-Doherty Earth Observatory have found evidence of hydrothermal vents on the seafloor near Antarctica, formerly a blank spot on the map for researchers wanting to learn more about seafloor formation and the bizarre life forms drawn to these extreme environments.

Dolphins’ Health Shed Light on Human and Ocean Health

The Georgia Dolphin Health Assessment capture-release study provides information on the health of the wild dolphin population that inhabits estuaries along the Georgia coast.

A panel of governmental, academic and non-profit scientists speaking at the annual meeting of the American Association for the Advancement of Science (AAAS) unveiled research suggesting that diseases found in dolphins are similar to human diseases and can provide clues into how human health might be affected by exposure to contaminated coastal water or seafood.

Unusual Snail Shell Could Be a Model for Better Armor

Nature’s clues about about next generation armor

A recently discovered gastropod from the Kairei Indian hydrothermal vent, called Crysomallon squamiferum, has an unusual shell structure superbly suited for protecting it against penetration attack.

Deep within the Kairei Indian hydrothermal vent field, two-and-one-half miles below the central Indian Ocean, scientists have discovered a gastropod mollusk, whose armor could improve load-bearing and protective materials in everything from aircraft hulls to sports equipment.

Deep-Sea World Beyond Sunlight: Explorers Census 17,650 Ocean Species on Edge of Black Abyss

091122161740-large

he nine known species of rare, primitive finned octopods are commonly called “Dumbos” because they flap a pair of large ear-like fins to swim, akin to the cartoon flying elephant.

Census of Marine Life scientists have inventoried an astonishing abundance, diversity and distribution of deep sea species that have never known sunlight — creatures that somehow manage a living in a frigid black world down to 5,000 meters (~3 miles) below the ocean waves.

Bizarre Lives Of Bone-eating Worms

091109194741

This photograph shows a female of an as yet un-named boneworm in the genus Osedax, which has been carefully removed from the whale bone in which it was growing.

It sounds like a classic horror story — eyeless, mouthless worms lurk in the dark, settling onto dead animals and sending out green “roots” to devour their bones. In fact, such worms do exist in the deep sea. They were first discovered in 2002 by researchers at the Monterey Bay Aquarium Research Institute (MBARI), who were using a robot submarine to explore Monterey Canyon. But that wasn’t the end of the story. After “planting” several dead whales on the seafloor, a team of biologists recently announced that as many as 15 different species of boneworms may live in Monterey Bay alone.

African Desert Rift Confirmed As New Ocean In The Making

091102172037-large

New research confirms that the volcanic processes at work beneath the Ethiopian rift are nearly identical to those at the bottom of the world’s oceans, and the rift is indeed likely the beginning of a new sea.

In 2005, a gigantic, 35-mile-long rift broke open the desert ground in Ethiopia. At the time, some geologists believed the rift was the beginning of a new ocean as two parts of the African continent pulled apart, but the claim was controversial.

Plagne site where sauropod dinosaur tracks were discovered. September 2009.

Footprints from sauropod dinosaurs, giant herbivores with long necks, were found in Plagne, near Lyon, France. Discovered by Marie-Hélène Marcaud and Patrice Landry, two nature enthusiasts, the dinosaur footprints have been authenticated by Jean-Michel Mazin and Pierre Hantzpergue, both of the Paléoenvironnements et Paléobiosphères laboratory
