Hurricane Sandy 2012 Photos

This NOAA satellite image taken Sunday, Oct. 28, 2012 shows Hurricane Sandy off the Mid Atlantic coastline moving toward the north with maximum sustained winds of 75 mph. Tens of thousands of people were ordered to evacuate coastal areas Sunday as big cities and small towns across the U.S. Northeast braced for the onslaught of a superstorm threatening some 60 million people along the most heavily populated corridor in the nation.

Ocean’s Color Can Change Hurricane Patterns

Chlorophyll concentrations worldwide; Image via SeaWiFS satellite of NASA Recent research shows that the color of the ocean can have a big influence on the occurence of hurricanes — the greener the ocean, the more hurricanes. And that’s a good thing. The ocean’s tint comes from the presence of chlorophyll, the green pigment in phytoplankton that helps the organisms convert sunlight into food, and thus forms the foundation of the oceanic food chain, as well as a prime environment for hurricanes. However, as we recently pointed out in another study, warming temperatures of the oceans are having a negative impact on

Will Biodegrading Oil And Natural Gas From BP Gusher Expand The Gulf Dead Zone?

Satellite view of the Gulf oil spill as of 12 June 2010 (partial excerpt). Image credit: SkyTruth, via NASA. So far, I have read only speculation about the ‘Dead Zone’ expanding as a result of increased biological oxygen demand (BOD), stemming from oil and natural gas in the Gulf. It is plausible that the Dead Zone size would be increased – assuming phytoplankton productivity is not reduced by oil and gas, which would lead to reduced oxygen uptake as lower volumes… Read the full story on TreeHugger
