Reveal Hidden Dangers to Passing Ships

Using inflatable boats, a portable depth sounder with GPS, and a REMUS autonomous underwater vehicle, a team of scientists and engineers has created the first detailed, comprehensive chart of the ocean floor around Palmer Station in Antarctica, revealing previously unknown submerged rocks.

The new chart, the first in 50 years, was made by a research team from the Woods Hole Oceanographic Institution (WHOI) and the University of

Follow the carbon – this is the mantra of researchers seeking to understand climate change and forecast its likely extent. A workshop heard how improved detection of heat-trapping carbon dioxide from space promises to revolutionise carbon cycle understanding.

This week saw more than 60 researchers from Europe, the United States and Japan gather at ESRIN, ESA’s establishment in Italy, for the three-day Carbon from Space workshop, jointly organised by ESA, the Internationa

One of the biggest questions in modern oceanography is how animals in the deep sea get enough to eat. Marine biologists at the Monterey Bay Aquarium Research Institute (MBARI) recently published a paper that helps answer this question, at least for animals that live on the deep seafloor off the coast of Central California. After analyzing hundreds of hours of deep-sea video, Bruce Robison and his colleagues found that “sinkers”—the cast-off mucus nets of small midwater animals called larvacea

Most of the excess carbon dioxide pouring into the atmosphere from the burning of fossil fuels will ultimately be absorbed by the oceans, but it will take about 100,000 years. That is how long it took for ocean chemistry to recover from a massive input of carbon dioxide 55 million years ago, according to a study published this week in the journal Science.

James Zachos, professor of Earth sciences at the University of California, Santa Cruz, led an international team of scientists t

A team of European and US scientists, using Cassini-Huygens data, have found that Saturn’s smoggy moon Titan may have volcanoes that release methane in the atmosphere.

These findings may lead scientists to revise the theories that the presence of methane in Titan’s atmosphere is mainly due to the presence of a methane-rich hydrocarbon ocean.

Infrared images taken by the Visual and Infrared Mapping Spectrometer (VIMS) on board the Cassini orbiter, show a bright, 30-kilom

Highlights from final report on December 26, 2004 tsunami’s impact in Banda Aceh

Waves more than 15 meters (49 feet) high. Flooding of 25 square miles of land. A coastline moved a mile. In a brief report in the June 9, 2005 issue of Science, University of Southern California tsunami expert Jose Borerro presents the results of the detailed survey he made on the scene at Banda Aceh, Indonesia following the Dec. 26 earthquake and tsunami

Banda Aceh and the nearby area of
