Jakarta (AFP) July 8, 2010
US and Indonesian scientists on Thursday launched a joint expedition to map some of the deepest oceanic trenches in the world for clues on biodiversity and volcanic vents, officials said.

The US embassy in Jakarta said the first joint expedition by Indonesia and the United States marked the beginning of a "multi-year partnership to advance ocean science, technology and education".

"Indonesian waters are home to more marine biodiversity than any place else in the world," Jane Lubchenco, under secretary of commerce for oceans and atmosphere, said in a statement.

"We explore together to better understand, use, and protect the ocean and its resources."

The work is being done by the National Oceanic and Atmospheric Administration (NOAA) and Indonesia's Marine and Fisheries Research.

NOAA ship Okeanos Explorer will send live images and other data from the sea to scientists ashore in Indonesia and the United States.

The ship is fitted with a deep water multibeam sonar mapping system and a remotely operated submarine which can dive to a depth of 6,000 metres (19,700 feet).

Data and images can be beamed from the vehicle to the shore in real-time using the ship's "telepresence" technology, a kind of high-speed Internet.

"Explorers expect discoveries that will advance our understanding of undersea ecosystems and volcanic hydrothermal vent activity where biologically unique communities typically are found," an embassy statement said.

"Discoveries could also advance understanding of ocean acidification processes and provide new information on deep ocean volcanically-derived gases such as carbon dioxide that have a role in climate and ecosystem variability."

The joint research is the result of President Barack Obama's call for stronger scientific ties between the United States and developing countries, particularly from the Muslim world, it added.

More Fish Than Thought May Thrive In The Ocean's Depths
Washington DC (SPX) Jul 07, 2010
A study of the occurrence of fishes in the ocean's deepest reaches-the hadal zone, below 6000 meters-has provided evidence that some species of fishes are more numerous at such depths than experts had thought. The authors of the study, which is published in the July/August issue of BioScience, observed 10 to 20 snailfish congregating at a depth of 7703 meters around a baited video lander i ... read more
