New research could help with the large-scale cultivation and manufacturing of oil-rich algae in oceans for biofuel. Algae are a diverse and simple group of organisms that live in or near water. Certain algal species are high in oil content that could be converted into such fuels as biodiesel, according researchers. Algae also have several environmentally-friendly advantages over corn or other plants used for biofuels, including not needing soil or fresh water to grow.
Fire Under Arctic Ice: Volcanoes Have Been Blowing Their Tops In The Deep Ocean
06:39 26-06-2008; source: www.sciencedaily.com
Researchers have uncovered evidence of explosive volcanic eruptions deep beneath the ice-covered surface of the Arctic Ocean. Such violent eruptions of splintered, fragmented rock -- known as pyroclastic deposits -- were not thought possible at great ocean depths because of the intense weight and pressure of water and because of the composition of seafloor magma and rock. The evidence of violent eruptions on Gakkel Ridge in the Arctic defies assumptions about seafloor pressure and volcanism.

Census of Marine Life-affiliated scientists consolidating world databases of ocean organisms have demoted to alias status almost one-third of all names culled so far from 34 regional and highly specialized inventories. Experts will complete the World Register of Marine Species by October 2010 as part of the first Census of Marine Life.
Destruction Of Greenhouse Gases Over Tropical Atlantic May Ease Global Warming

Large amounts of ozone are being destroyed in the lower atmosphere over the tropical Atlantic Ocean. The significance is that ozone in the lower atmosphere acts as a greenhouse gas and its destruction also leads to the removal of the third most abundant greenhouse gas; methane. It should lead to improved climate predictions.

Looming Tropical Disaster Needs Urgent Action, According To New Report

A major review shows that the world is losing the battle over tropical habitat loss with potentially disastrous implications for biodiversity and human well-being. Tropical forests support more than 60% of all known species. But up to 15 million hectares of tropical rainforest are being lost every year and species are being lost at a rate of up to 10,000 times higher than would happen randomly without humans present.
