 Scientists Look to Microbes to Unlock Earth's Deep Secrets

Of all the habitable parts of our planet, one ecosystem still remains largely unexplored and unknown to science: The igneous ocean crust. This rocky realm of hard volcanic lava exists beneath ocean sediments that lie at the bottom of much of the world's oceans. While scientists have estimated that microbes living in deep ocean sediments may represent as much as one-third of Earth's total biomass, the habitable portion of the rocky ocean crust may be 10 times as great.

The Reality of Extreme Weather, Part 1

This report is the first in a two-part series chronicling recent findings about climate change. Part 2, to be published in our Jan. 19 issue, examines “What Can Be Done.”

Multi-year prediction of Atlantic Meridional Overturning Circulation at 26.5 °N possible

Climate scientists have now shown for the first time that the strength of the Atlantic Meridional Overturning Circulation at 26.5 °N can be skillfully predicted for up to four years.

Researchers Find New Species Around Antarctic Hot Springs

Oceanographers exploring some of the most remote deep-sea hot springs have discovered one distinct biological zone teeming with life that nobody ever knew existed.

Debris scatters in the Pacific Ocean, possibly heading to US

Debris from the tsunami that devastated Japan in March could reach the United States as early as this winter, according to new predictions. However, they warn there is still a large amount of uncertainty over exactly what is still floating, where it's located, where it will go, and when it will arrive. Responders now have a challenging, if not impossible situation on their hands: How do you deal with debris that could now impact US shores, but is difficult to find?

Sea cucumbers: Dissolving coral reefs?

Coral reefs are extremely diverse ecosystems that support enormous biodiversity. But they are at risk. Carbon dioxide emissions are acidifying the ocean, threatening reefs and other marine organisms. New research analyzed the role of sea cucumbers in portions of the Great Barrier Reef and determined that their dietary process of dissolving calcium carbonate (CaCO3) from the surrounding reef accounts for about half of at the total nighttime dissolution for the reef.

Sensing the deep ocean

Sensorbots are spherical devices equipped with biogeochemical sensors, that promise to open a new chapter in the notoriously challenging exploration of earth's largest ecosystem -- the ocean.

Will Antarctic worms warm to changing climate?

Researchers are examining tiny worms that inhabit the frigid sea off Antarctica to learn not only how these organisms adapt to the severe cold, but how they will survive as ocean temperatures increase.

Comprehensive Study Makes Key Findings of Ocean pH Variations

 Some organisms already experiencing ocean acidification levels not predicted to be reached until 2100.

Climate Change and Other Threats to World's Freshwater Goliaths

Large Lakes Observatory works toward deeper understanding of how lakes function.

 Scientists Assess Radioactivity in the Ocean From Japan Nuclear Power Facility

New study analyzes radioactivity from facility in first months after accident

Tropical sea temperatures influence melting in Antarctica

New research shows that accelerated melting of two fast-moving glaciers that drain Antarctic ice into the Amundsen Sea Embayment is likely in part the result of an increase in sea-surface temperatures in the tropical Pacific Ocean.

NASA sees birth of first Southern Indian Ocean season tropical storm

The Southern Indian Ocean cyclone season is off and running and NASA's Aqua satellite saw the birth of Tropical Cyclone 01S.

Submarine Springs Offer Preview of Ocean Acidification Effects on Coral Reefs 

Observations at submarine springs found along the coast of Mexico's Yucatan Peninsula are giving scientists a preview of the possible fate of coral reef ecosystems in response to ocean acidification.
