The emergence of new species can revolutionize what is known about the dark hidden life of the planet.

A group of scientists from the University of Aberdeen (Scotland) has been discovered in the Atlantic Ocean more than ten possible new marine species, some of them extremely rare, which they say have revolutionized their thinking about life in the deep seabed. According to the researchers, the animals captured during six weeks aboard the RRS James Coo, can be close to the evolutionary missing link between vertebrates and invertebrates. (more…)

For the first time, a field study has shown that several common species of seaweed in the Pacific Ocean and Caribbean Sea can kill corals by contact using average chemicals. (more…)

A deep ocean current, with a volume equivalent to 40 times that of Amazon, has been discovered by Japanese and Australian scientists near the Kerguelen Plateau in the Southern Ocean sector for the Indian Ocean, about 4,200 kilometers southwest of Perth, a city of the west coast of Australia.

The researchers, who include Steve Rintoul from CSIRO, have presented the results of an investigation which describe the current, which circulates to more than three miles beneath the ocean’s surface and show its important role within the global network ocean currents that influence climate patterns.

Working in an unusual “natural laboratory seabed” of hydrothermal vents that had just been rocked by a volcanic eruption, a group of scientists from the Woods Hole Oceanographic Institution (WHOI) and other institutions has discovered what could be described as a path Underwater settlers.
The discovery of hydrothermal vents at the bottom of the Pacific Ocean in 1977, revolutionized ideas about where and how life can exist.

Seafloor vents, spewing hot fluids, rich in minerals and full of life around, raised new questions that researchers have been trying to answer since then, including: How much life can thrive in the seabed without sunlight? What is the nature of these organisms in hydrothermal vents? How the animals migrated to other vents? (more…)

Scientists from Lamont-Doherty Observatory of Columbia University have found evidence of hydrothermal vents on the seafloor around Antarctica, before a blank spot on the map to researchers trying to get new light on the formation of the bed Marine and strange life forms that inhabit these extreme environments.

Hydrothermal vents expel volcanically heated sea water from the submarine ridges in the world. They constitute a vast system of mountains in the central regions of the oceans, where lava flows and form new crust. Chemicals dissolved in these vents affect ocean chemistry and sustain a complex network of agencies, in a similar way to how do the sunlight on the surface. Most of the deep ocean is like a desert, but these vents are oases for life. In recent decades, more than 220 vents have been discovered in various parts of the world, but so far no one had searched in the icy waters near Antarctica. (more…)
