Australia: Giant ocean eddy shadows Sydney

The giant ocean eddy that cooled Sydney's shores a year ago has been superseded by another 300 km diameter giant.

CSIRO Wealth from Oceans National Research Flagship scientist, Dr David Griffin, says the 'birth' of the eddy has been traced to last August.

"From satellite maps of sea-level we can see that it had been loitering this side of Lord Howe Island for some time and began approaching the NSW coast near Christmas," Dr Griffin says.

"It remained stationary during January and simply grew larger but, because it remained offshore, less people would have noticed its impacts on water temperatures."

The cold water at the new eddy's centre has welled up about 500m from the ocean depths.

Bee plague worsening, anxious keepers say

It's been 16 months since Dave Hackenberg of Dade City became the first beekeeper in the country to say publicly that something was terribly wrong with his insects.

In the intervening time following the identification of the malady now known as Colony Collapse Disorder, things haven't gotten any better for the nation's bees, which pollinate about one-third of U.S. crops - some $15 billion worth.

Global Warming Could Radically Change Lake Tahoe In Ten Years

A new UC Davis study predicts that climate change will irreversibly alter water circulation in Lake Tahoe, radically changing the conditions for plants and fish in the lake -- and it could happen in 10 years.

One likely result would be a warmer lake overall, with fewer cold-water native fish, and more invasive species, such as large-mouth bass, bluegill and carp.

Still unclear is how the changes would affect the lake's phenomenal clarity and cobalt-blue color, which have helped to make the Tahoe Basin an international vacation destination.

The new findings were announced March 18 at a Tahoe scientific conference by three lake experts from the Tahoe Environmental Research Center at UC Davis -- Director Geoffrey Schladow, Associate Director John Reuter and postdoctoral researcher Goloka Sahoo.
