Glimpse into the future of acidic oceans shows ecosystems transformed

Posted: 08 Jul 2013 02:10 PM PDT

In the waters surrounding Castello Aragonese, a 14th century castle off the coast of Italy, volcanic vents naturally release bubbles of carbon dioxide gas, creating different levels of acidity among the marine-animal and plant communities there. These gradients of acidity gave scientists a glimpse of what a future marked by increasingly acidic ocean waters could look like, and how the creatures and plants living in those environments may react to it.

Finding the Goldilocks sites to store carbon dioxide underground

To implement carbon capture and storage successfully, each underground repository will need careful appraisal based on its unique history and setting, according to a new study.

Innovative study estimates extent to which air pollution in China shortens human lives

A high level of air pollution, in the form of particulates produced by burning coal, significantly shortens the lives of people exposed to it, according to a unique new study of China.

NASA’s polar robotic ranger passes first Greenland test

Posted: 08 Jul 2013 11:33 AM PDT

Defying 30 mph gusts and temperatures down to minus 22 F, NASA’s new polar rover recently demonstrated in Greenland that it could operate completely autonomously in one of Earth’s harshest environments.

‘Dead zone’ impacts Chesapeake Bay fishes

Posted: 08 Jul 2013 11:31 AM PDT

A 10-year study provides the first quantitative evidence on a bay-wide scale that low-oxygen “dead zones” are impacting the distribution and abundance of “demersal” fishes — those that live and feed near the Bay bottom.

Sydney’s urban areas to be hit hardest by global warming

Posted: 08 Jul 2013 08:51 AM PDT

Green spaces, trees and bodies of water are must-have design features for future development in Sydney’s suburbs after researchers found that by 2050 global warming combined with Sydney’s urban heat island effect could increase temperatures by up to 3.7°C.

Researchers warn of legacy mercury in the environment

Posted: 08 Jul 2013 08:45 AM PDT

Environmental researchers have published evidence that significant reductions in mercury emissions will be necessary just to stabilize current levels of the toxic element in the environment. So much mercury persists in surface reservoirs (soil, air, and water) from past pollution, going back thousands of years, that it will continue to persist in the ocean and accumulate in fish for decades to centuries, they report.

Deep sea isolation: Hypersaline ‘islands’ harbor unique life

Posted: 08 Jul 2013 07:33 AM PDT

Deep in the ocean exist super salty anoxic basins that form ‘islands’ allowing evolution to vary between communities of ciliated plankton. These unique communities provide an opportunity to observe multiple results of evolution from the same stock and different solutions to environmental difficulties.
