Expedition achieves milestone in analyzing atmospheric chemistry

A research consortium funded by the National Science Foundation (NSF) and led by the Scripps Institution of Oceanography at the University of California, San Diego, has successfully sent a fleet of aerial drones through the pollution-filled skies over the Indian Ocean, thereby achieving an important milestone in the tracking of pollutants responsible for dimming Earth’s atmosphere.

Plans to drill deep beneath the frozen wastes of the Antarctic, to investigate subglacial lakes where ancient life is thought to exist, may have to be reviewed following a discovery by a British team led by UCL (University College London) scientists at the Natural Environment Research Council (NERC)Centre for Polar Observation and Modelling (CPOM).

In a Letter to Nature they report that rivers the size of the Thames have been discovered which are moving water hundreds of mile

Dutch researcher Yvonne van Breugel analysed rocks from seabeds millions of years old. Carbon occurs naturally in two stable forms; atomic mass 12 (99 percent) and atomic mass 13 (1 percent). Episodes in the Jurassic and Cretaceous periods were characterised by a relatively strong increase in 12C. The analyses have shown that this was caused by a sudden large-scale release of carbon from stocks stored in the ocean floor or peats and bogs.

Scripps-led Project Achieves Milestone in Analyzing Pollutants Dimming the Atmosphere

Technology behind unmanned aerial vehicles proves successful for flying beneath, above and through clouds to trace pollution particles

A scientific research consortium led by Scripps Institution of Oceanography at the University of California, San Diego, has reached an important milestone in the tracking of pollutants responsible for dimming Earth’s atmosphere.

Scientists at the Woods Hole Oceanographic Institution (WHOI) have completed two extensive survey and mapping efforts to better understand why the 2005 New England red tide was so severe and to suggest what might lie ahead. WHOI Senior Scientist Don Anderson and colleagues mapped the distribution of Alexandrium fundyense cysts in seafloor sediments immediately before and after the historic harmful algal bloom of 2005.

The first of these analyses shows unusually large numbers of cysts o

Scientists have reported an unprecedented number of unaccompanied and possibly abandoned walrus calves in the Arctic Ocean, where melting sea ice may be forcing mothers to abandon their pups as the mothers follow the rapidly retreating ice edge north.

Nine lone walrus calves were reported swimming in deep waters far from shore by researchers aboard the U.S. Coast Guard icebreaker Healy during a cruise in the Canada Basin in the summer of 2004. Unable to forage for themselves, th
