14-07-14 Imagine the open ocean as a microbial megacity（大城市） , teeming with（富于，充满） life too small to be seen. In every drop of water, hundreds of types of bacteria can be found. Now scientists have discovered that communities of these ocean micro...

14-07-02 Thought to dwell（居住，存在于） mostly near the ocean's surface, Chilean devil rays (Mobula tarapacana) are most often seen gliding through shallow, warm waters. But a new study by scientists at Woods Hole Oceanographic Institution (WHOI) and inter...

14-06-30 For decades, climate scientists have tried to explain why ice-age cycles became longer and more intense about 900,000 years ago, switching from 41,000-year cycles to 100,000-year cycles. In a new study in the journal Science, researchers found that...

14-06-16 If the icy surface of Pluto's giant moon Charon is cracked, analysis of the fractures could reveal if its interior was warm, perhaps warm enough to have maintained a subterranean（地下的，秘密的） ocean of liquid water, according to a new NASA-funde...

14-04-25 Scientists have conclusive evidence that the source of a unique rhythmic sound, recorded for decades in the Southern Ocean and called the bio-duck, is the Antarctic minke whale（小须鲸） (Balaenoptera bonaerensis). First described and named by subma...

14-03-28 Scientists monitored Cuvier's beaked whales' record-breaking dives to depths of nearly two miles below the ocean surface and some dives lasted for over two hours, according to results published March 26, 2014, in the open access journal PLOS ONE by...

14-03-25 The top predators of the Southern Ocean, far-ranging seabirds, are tied both to the health of the ocean ecosystem and to global climate regulation through a mutual relationship with phytoplankton（浮游植物） , according to newly published work from...

14-03-24 Far beneath the surface of the ocean, deep currents act as conveyer belts, channeling heat, carbon, oxygen and nutrients around the globe. A new study by the University of Pennsylvania's Irina Marinov and Raffaele Bernardello and colleagues from McG...

14-03-05 In the mid-1970s, the first available satellite images of Antarctica during the polar winter revealed a huge ice-free region within the ice pack of the Weddell Sea. This ice-free region, or polynya（冰间湖） , stayed open for three full winters befo...
