Envisat fishes up facts behind Chilean giant squid invasion

Masses of large ocean-going squid have inundated the shores of Southern Chile, alarming local fishermen who fear these carnivorous invaders could threaten fish stocks. Envisat has helped account for their otherwise mysterious arrival.

These jumbo flying squid – Dosidicus gigas is their Latin name – are some of the largest known squids on the planet: the ones here measure between 70 to 150 centimetres in length, although specimens have been known to reach more than three metres. Making their

From Jupiter’s Moon, Io, come ideas about what Earth may have looked like as a newborn planet

Lava lakes could be Ionian versions of Earth’s mid-ocean ridges

Investigations into lava lakes on the surface of Io, the intensely volcanic moon that orbits Jupiter, may provide clues to what Earth looked like in its earliest phases, according to researchers at the University at Buffalo and NASA’s Jet Propulsion Laboratory.
“When I look at the data, it becomes startlingly suggestive to me that this may be a window onto the primitive history of Earth,” said Tracy K. P. G

Scientists find new carbon pollution called ’tar balls’

An international team of scientists has discovered new carbon-bearing particles, which they call “tar balls,” in air pollution over Hungary, the Indian Ocean, and southern Africa. Tar balls form in smoke from wood fires and agricultural and forest burning. Carbon-bearing particles like tar balls in the lower atmosphere are a concern, they say, because they may affect global climate change, as well as air quality.

The team, headed by Mihály Pósfai, an Earth and environmental science professo

NASA Explains "Dust Bowl" Drought

NASA scientists have an explanation for one of the worst climatic events in the history of the United States, the “Dust Bowl” drought, which devastated the Great Plains and all but dried up an already depressed American economy in the 1930’s.

Siegfried Schubert of NASA’s Goddard Space Flight Center, Greenbelt, Md., and colleagues used a computer model developed with modern-era satellite data to look at the climate over the past 100 years. The study found cooler than normal tropical

Europe at the forefront in research on solar, wave and geothermal energies

Today at the “Solar platform” test site in Almeria (Spain) the European Commission presented the state of play on its research programmes in alternative energy sources, including solar thermal, wave and geothermal energy. World energy consumption will double over the next 50 years, with Europe currently depending heavily on foreign energy sources. Currently, 41% of EU energy consumption is based on oil, followed by gas (23%), coal (15%), nuclear (15%) and only 6% is based on renewable energies. The t

Isolated corals reefs are at risk from global climate change

For species such as corals the dispersal of their larvae and restocking of damaged reefs is critical to their ability to survive the changes produced by global warming.

In the latest issue of Ecology Letters, David Ayre and Terry Hughes from the Australia’s Wollongong and James Cook Universities have for the first time used genetic data to show that individual coral reefs within the world’s largest tropical reef system (the Great Barrier Reef) must be buffered against such change
