New deep-sea hydrothermal vents discovered in Gulf of California

Scientists have uncovered clusters of volcanic vents towering above the seafloor in a region of deep-sea off the coast of Mexico. The so-called "black smoker" vents lie about 7,400 meters (7,900 feet) deep with chimneys reaching 23 meters (75 feet). These

Deep seafloor could help scientists predict earthquakes

Seismic monitoring and centuries of experience have given humankind a pretty good idea of what areas are prone to the devastation of earthquakes and tsunamis. But to truly prepare for huge temblors and accompanying tsunamis like the one that ravaged Japan in March, we

Dead Sea disappearing day by day

The Dead Sea has been drying up at a dramatic rate in recent decades as a result mostly of human demands for water. But instead of letting the historic body of water continue to disappear, some scientists are getting increasingly serious about trying to save it.In

Two small islands have sunk into the sea between India and Sri Lanka

Two small islands in South Asia's first marine biosphere reserve have sunk into the sea primarily as a result of coral reef mining. The islets were in a group in the Gulf of Mannar, between India and Sri Lanka.The Indo-Pacific region is considered to contain some of

Deep-sea volcanoes could also explode

Between 75 and 80 % of all volcanic activity on Earth takes place at deep-sea, mid-ocean ridges. Most of these volcanoes produce effusive lava flows rather than explosive eruptions, both because the levels of magmatic gas (which fuel the explosions and are made up of a

Fault-Finding Coral Reefs Can Predict the Site of Coming Earthquakes

In the wake of the devastating loss of life in Japan, the urgent question is where the next big earthquake will hit. To answer it, geologist Prof. Zvi Ben-Avraham and his doctoral student Gal Hartman of Tel Aviv University's Department of Physics and Planetary Sciences

Japanese tsunami and Pacific ocean floor

As tsunami waves travel across ocean basins they are only inches high, but extend down to the ocean floor (unlike traditional waves which are only surface features). As the tsunami waves approaches the coast, the shallowing ocean floor pushes the water mass upwards.

Arctic's spring phytoplankton blooms arrive earlier

When summer comes to the Arctic, the tiny plants that feed the ocean's food chain form green blooms in the water. In some Arctic waters, the peak of this bloom has been arriving earlier every year since 1997, a study has found. These areas, where peak bloom
