New Look at 1918/1919 El Niño Suggests Link to Flu Pandemic

Tuesday, February 9th, 2010

El Niño—Spanish for the child—is the name climate scientists have given the occasional periods of Pacific Ocean warming that play havoc with global weather patterns. For example, El Niño is known to intensify winter storms for residents of the West Coast, Gulf states, and southeast United States. El Niño also dampens Atlantic hurricane formation and can increase the number of Pacific hurricanes.

Discovery of Algae’s Toxic Hunting Habits Could Help Curb Chesapeake Fish Kills

Monday, February 1st, 2010

A microbe commonly found in the Chesapeake Bay and other waterways emits a poison not just to protect itself but to stun and immobilize the prey it plans to eat, a team of researchers from four universities has discovered. The findings about algae linked to massive fish kills could lead to new ways to slow the growth of these tiny but toxic marine creatures.

Meet the creatures that live beyond the abyss

Shipwrecks Offer Clues to Ancient Cultures

Tuesday, December 29th, 2009

Brendan Foley hunts for shipwrecks, but he’s not searching for gold or jewels. The sunken treasure he pursues comes not in chests, but mostly in curvaceous clay jars called amphorae—the cargo containers of the B.C. world. Holding remnants of goods and foodstuffs produced and traded by ancient civilizations,

Ocean Losing Its Appetite for Carbon

Tuesday, December 29th, 2009

The world’s oceans, which normally gobble up carbon dioxide, are getting stuffed to the gills, according to the most thorough study to date of human-made carbon in the seas.

CO2 Emissions Continue Significant Climb

Wednesday, December 2nd, 2009

The annual rate of increase in carbon dioxide emissions from fossil fuels has more than tripled in this decade, compared to the 1990s, reports an international consortium of scientists, who paint a bleak picture of the Earth’s future unless “CO2 emissions [are] drastically reduced.”

In CO2-rich Environment, Some Ocean Dwellers Increase Shell Production

Wednesday, December 2nd, 2009

In a striking finding that raises new questions about carbon dioxide’s (CO2) impact on marine life, Woods Hole Oceanographic Institution (WHOI) scientists report that some shell-building creatures—such as crabs, shrimp and lobsters—unexpectedly build more shell when exposed to ocean acidification caused by elevated levels of atmospheric carbon dioxide (CO2).
