Using chaos to model geophysical phenomena

Geophysical phenomena such as the dynamics of the atmosphere and ocean circulation are typically modeled mathematically by tracking the motion of air or water particles. These mathematical models define velocity fields that, ...

Geologist says there's no need to fight over mineral resources

It's easy to be a pessimist in a world full of calamities. But for those worried about the continuing availability of natural resources, data from the ocean makes a good case for optimism, says economic geologist Lawrence ...

Water mission reveals insight into Amazon plume

(PhysOrg.com) -- ESA's SMOS water mission has taken another step forward by demonstrating that it will lead to a better understanding of ocean circulation. Using preliminary data, scientists can clearly see how surface currents ...

GOCE giving new insights into Earth's gravity (w/ Video)

(PhysOrg.com) -- The first global gravity model based on GOCE satellite data has been presented at ESA's Living Planet Symposium. ESA launched GOCE in March 2009 to map Earth's gravity with unprecedented accuracy and resolution.

Ocean stirring and plankton patchiness

Computer simulations performed by researchers at the National Oceanography Centre and the University of Glasgow show how oceanic stirring and mixing influence the formation and dynamics of plankton patches in the upper ocean.

CCNY leads study to identify top NJ tidal power generation sites

With a coastline stretching from New York Harbor to Cape May, New Jersey stands to benefit from a new study designed to pinpoint the top 20 sites for hydrokinetic energy, a renewable resource produced by the movement of tides, ...

Climate: El Nino weakens, La Nina threatens

The Pacific weather pattern known as El Nino is all but gone, climate scientists say, while its alter ego, La Nina, might soon appear on the horizon.

GOCE satellite determines gravitational force in the Himalayas

ESA's GOCE satellite has been orbiting the Earth for more than a year and surveying its gravitational field more accurately than any instrument previously. The goal of the researchers - including German scientists at the ...
