The high cost of steam and the lesser need for speed kept the majority of the world's ocean freight moving by sail until the early years of the 20th century.

When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong.

Around half of ocean heat intake since 1865 has taken place since 1997, researchers report online in Nature Climate Change.

El niño, Spanish for "the child", occurs when surface ocean waters in the southern Pacific become abnormally warm.

Even though pumping from these depths is expensive, it is still cheaper than desalinating (脱盐) the ocean water in the largely coastal state.

Gazing down on the city from the Getty Center, an art museum in the Santa Monica Mountains, one would find the view of the Pacific Ocean blurred by the haze.

Her father had written the note as a joke and had thrown it into the Atlantic Ocean.

like humans, killer whales have colonized a range of different habitats across the globe, occupying every ocean basin on the planet, with an empire that extend from pole to pole.

Marine life may be affected too: El niños can reduce the rising of the cold, nutrient-rich water that supports large fish 35 populations, and the unusually warm ocean temperatures can destroy coral.

The extensive data sources, combined with computer simulations, created a timeline of ocean temperature changes, including cooling from volcanic outbreaks and warming from fossil fuel emissions.

The note inside the bottle said, "Return to 419 Ocean Street and receive a reward of $150 from Richard and Tina pierce, owners of the Beachcomber Motel."

The researchers gathered 150 years of ocean temperature data in order to get a better picture of heat absorption from surface to seabed.

They gathered together temperature readings collected by everything from a 19th century voyage of British naval ships to modern automated ocean probes.

While the top of the ocean is studied, its depths are more difficult to explore.

Earlier this year, British explorer  Hadow and his team trekked for three months across the frozen Arctic Ocean, taking measurements and recording observations about the ice.

South Korea, which operates state-of-the-art bases here, is increasing its fishing of krill ( ' , 磷虾), found in abundance in the Southern Ocean, while Russia recently frustrated efforts to create one of the world's largest ocean sanctuaries here.

Efforts to create one of the world's largest ocean sanctuaries failed because of Russia's obstruction.

Way up north in the Canadian Arctic, seabirds are picking up dangerous chemicals in the ocean and delivering them to ponds near where the birds live.

The pollutants in the ponds appear to come from fish that fulmars eat when they’re out on the ocean.

The picture worsens with each round of El Nino, the unusually warm currents in the Pacific Ocean that drive up temperatures and invariably presage (预示) droughts and fires in the rain forest.

It sits firmly on solid rock at the bottom of the ocean.

The West Antarctic region was once an open ocean

They found fossils of microscopic marine plants which suggest that the region was once open ocean not solid ice.

If such an earthquake happened today, it would be felt from the Rocky Mountains to the Atlantic Ocean and would flatten most of the cities in the Mississippi valley.

A global campaign has been launched to create a network of ocean sanctuaries to protect the seas in the region and Greenpeace is calling for an immediate halt to fishing in areas being considered for sanctuary status.

A global campaign has been launched to turn a huge tract of Antarctic seas into ocean sanctuaries, protecting wildlife and banning not just krill fishing, but all fishing.

As the ocean warms, a body of water called the Antarctic Polar Front - an upward movement of nutrient-rich sea that supports a huge abundance of marine life - is being pushed further south. This means that king penguins, which feed on fish and krill in th

But its surface has been cooked and dried by an ocean of carbon dioxide, trapped in the burning death grip of a runaway greenhouse effect.

Earlier this year, British explorer Hadow and his team trekked for three months across the frozen Arctic Ocean, taking measurements and recording observations about the ice.

Frida Bengtsson from Greenpeace's Protect the Antarctic campaign said: "If the krill industry wants to show it’s a responsible player, then it should be voluntarily getting out of any area which is being proposed as an ocean sanctuary, and should instead

Island communities have been among the hardest hit by the threats facing the ocean, said President Tommy Remengesau Jr. in a statement.

Keith Reid, a science manager at CCAMLR, said that the organisation sought "a balance between protection, conservation and sustainable fishing in the Southern Ocean".

king penguins are the second-largest type of penguin and only breed on specific isolated islands in the Southern Ocean where there is no ice cover and easy access to the sea.

Only a handful of islands in the Southern Ocean are suitable for sustaining large breeding colonies.

We want to lead the way in restoring the health of the ocean for future generations.

We're looking at roughly 80 percent loss of ice cover on the Arctic Ocean in 10 years, roughly 10 years, and 100 percent loss in nearly 20 years.
