Life 500 Meters Below the Juan de Fuca Ridge|
May 16, 2013 | Deep Carbon Observatory
Researchers have discovered evidence of life 500 meters below the seafloor of the Juan de Fuca Ridge. “They found genetic evidence of Methanosarcinales, anaerobic archaea known to metabolize methane. Further experiments showed that microbes have affected the chemical signature of sulfur in the host basalt, suggesting they could harness energy from the breakdown of sulfates.” Quoted from the Deep Carbon Observatory press release.
Sea Level Rise and Small Pacific Islands|
April 18, 2013 | USGS
“Dynamic modeling of sea-level rise, which takes storm wind and wave action into account, paints a much graver picture for some low-lying Pacific islands under climate-change scenarios than the passive computer modeling used in earlier research.” Quote from the USGS press release.

This interesting article reviews some of the world’s important chokepoints for the transport of crude oil.
From the article: “Chokepoints are narrow channels along widely used global sea routes, some so narrow that restrictions are placed on the size of the vessel that can navigate through them. They are a critical part of global energy security due to the high volume of oil traded through their narrow straits.”
