Environmental disturbances such as El Niño shake up the marine food web off Southern California, new research shows, countering conventional thinking that the hierarchy of who-eats-who in the ocean remains largely constant over time.

A new study has found that conserving fish diversity in Madagascar's coral reef systems may depend on maintaining fish biomass above critical levels.

River deltas, with their intricate networks of waterways, coastal barrier islands, wetlands and estuaries, often appear to have been formed by random processes, but scientists see order in the apparent chaos.

Scientists have discovered that Earth's sea level did not rise steadily when the planet's glaciers last melted during a period of global warming; rather, sea level rose sharply in punctuated bursts.

Warmer ocean surface triggered the ice retreat during The Younger Dryas.

Researchers have retrieved original pigment, beta-keratin and muscle proteins from a 54-million-year-old sea turtle hatchling. The work adds to the growing body of evidence supporting persistence of original molecules over millions of years and also provi…

Scientists report that small seismic signals in lakes can aid science. As a record of wave motion in a lake, they can reveal when a lake freezes over and when it thaws. And as a small, constant source of seismic energy in the surrounding earth, lake micro…

An investigation of the different economic values of giant sea bass finds they are worth more alive as undersea wonders than as commercial catch.

For the first time, ocean data from Northeast Greenland reveals the long-term impact of the melting of the Greenland ice sheet. The observed increase in freshwater content will affect the conditions in all Greenland fjords and may ultimately affect the gl…

Ocean clams and worms are releasing a significant amount of potentially harmful greenhouse gas into the atmosphere, scientists have shown.

Hurricane-related financial loss could increase more than 70 percent by 2100 if oceans warm at the worst-case-scenario rate predicted by the Intergovernmental Panel on Climate Change, according to a new study. The study used a combination of hurricane mod…

While strong seasonal hurricanes have devastated many of the Caribbean and Bahamian islands this year, geologic studies on several of these islands illustrate that more extreme conditions existed in the past. A new analysis shows that the limestone island…

A review of geological evidence for tsunamis during the past 4500 years in the Mediterranean Sea has revealed that as many as 90 per cent of these inundation events may have been misinterpreted by scientists and were due to storm activity instead.
October 10th
Animal excrements and parts of dead organisms constantly sink from the surface of the oceans towards the deep sea. This particle flow plays an important role in the global carbon cycle and consequently for the climate. Little is known so far about its dis…

Because wind speeds are higher on average over ocean than over land, wind turbines in the open ocean could in theory intercept more than five times as much energy as wind turbines over land. This presents an enticing opportunity for generating renewable e…

The discovery of evidence for ancient sea-floor hydrothermal deposits on Mars identifies an area on the planet that may offer clues about the origin of life on Earth. The research offers evidence that these deposits were formed by heated water from a volc…

Category 5 hurricanes may have slammed Florida repeatedly during the chilly Younger Dryas, 12,000 years ago. The cause? Hurricane-suppressing effects of cooler sea surface were out-weighed by side effects of slowed ocean circulation.

Humans migrated out of Africa as the climate shifted from wet to dry about 60,000 years ago, according to new paleoclimate research. What the northeast Africa climate was like when people migrated from Africa into Eurasia between 70,000 and 55,000 years a…

One of the most economically important fish is shrinking in body weight, length and overall physical size as ocean temperatures rise, according to new research by LSU Boyd Professor R. Eugene Turner published today. The average body size of Menhaden -- a …

New research suggests that hydrogen, oxygen, water and carbon dioxide are being generated in the earth's mantle hundreds of kilometers below the earth's surface.
