On April 20, 2010, the oil rig Deepwater Horizon suffered an explosion and sank two days later. Shortly thereafter, oil began leaking into the Gulf of Mexico from ruptured pipes deep on the ocean floor. NASA satellites have been tracking the growth of the oil spill as it has spread towards the northern Gulf Coast.

Gulf coast residents braced Saturday for the arrival of a massive oil slick creeping toward shore as nearly a million feet of boom were deployed in an effort to protect precious estuaries and wildlife — even as thousands of barrels of crude continued gushing into the water.
The White House said today it is halting all new offshore drilling in U.S. waters until there’s an “adequate review” of a massive 600-mile-wide oil slick that has begun to drift into Louisiana’s wetlands.
In so many ways, Don Juan Pond in the Dry Valleys of Antarctica is one of the most unearthly places on the planet.
They paved paradise and, it turns out, actually did put up a parking lot. A big one. Some 700 feet deep in the waters off California’s jewel of a coastal resort, Santa Barbara, sits a group of football-field-sized asphalt domes unlike any other underwater features known to exist.
Researchers say they’ve taken underwater robotics to the next level, successfully running an autonomous robotic vehicle off the Hawaiian Islands for more than three months, powered only by energy harnessed from changes in sea temperatures.
Scientists who study the melting of Greenland’s glaciers are discovering that water flowing beneath the ice plays a much more complex role than they previously imagined.
A submarine exploring the ocean’s depths recently returned with an unexpected visitor: a crablike critter called Bathynomus giganteus (commonly known as giant isopod) that has left many readers startled and horrified.
A Chinese ship is in danger of breaking up after running aground off north-east Australia, sparking fears of a major oil spill into the Great Barrier Reef.
The drying up of the Aral Sea is one of the planet’s most shocking environmental disasters, U.N. Secretary-General Ban Ki-moon said Sunday as he urged Central Asian leaders to step up efforts to solve the problem.
AN EARLY warning system for destructive underwater waves has passed its first test in the Andaman Sea, north-west of Sumatra, Indonesia.
Lurking beneath waves of the Mediterranean, between Sicily and the Italian mainland, lies a submarine volcano, which is showing telltale signs of being unstable.
President Barack Obama reversed a ban on most offshore drilling, a move that could put Virginia at the forefront of East Coast oil and natural gas exploration.
Recent studies show that the oceans may hold more “garbage patches” of fine plastic flotsam than scientists realized and that the fragments extend well below the sea surface.
As the foreign ministers of five Arctic coastal states gather Monday for talks near Ottawa on the economic and environmental challenges facing the planet’s polar frontier, difficult questions linger over the region’s geopolitical future — highlighted by the exclusive guest list of the “Arctic Summit” itself.
A plan to combat global warming by fertilizing the ocean may backfire by triggering toxic algal blooms, a new study suggests.
This CBS video reports on the tsunami that threatened Hawaii as a result of the magnitude 8.8 earthquake that occurred on Saturday morning in Chile.
A tsunami that raced across the Pacific swiped island nations and Asian coasts lightly Sunday, proving to be more spectacle than destructive force for communities that had hours to prepare after Chile’s devastating earthquake.
Evidence from the Challenger Deep – the deepest surveyed point in the world’s oceans – suggests that tiny single-celled creatures called foraminifera living at extreme depths of more than ten kilometres build their homes using material that sinks down from near the ocean surface.
Layers of frozen seawater, known simply as sea ice, cap the Arctic Ocean. Ice grows dramatically each winter, usually reaching its maximum in March. The ice melts just as dramatically each summer, generally reaching its minimum in September. These image pairs show Arctic sea ice concentration for the month of September (left) and the following March (right) for a time series beginning in September 1999 and ending in March 2009.
