Volcanoes helped species survive ice ages

Volcanoes helped species survive ice ages

An international team of researchers has found evidence that the steam and heat from volcanoes and heated rocks allowed many species of plants and animals to survive past ice ages, helping scientists understand how species respond to climate change.

Largest flood recorded beneath Antarctica mapped by CryoSat

Largest flood recorded beneath Antarctica mapped by CryoSat

ESA’s CryoSat satellite has found a vast crater in Antarctica’s icy surface for which scientists believe was left behind when a lake lying under about 3 km of ice suddenly drained.

The study, published recently in Geophysical Research Letters,

Bedmap2 – detailed view of Antarctica’s landmass

Bedmap2 – detailed view of Antarctica’s landmass

Scientists at the British Antarctic Survey (BAS) have released the most detailed map yet of Antarctica’s landmass that allows scientists to better analyse the bed below the Antarctic ice sheet. Bedmap2 reveals a landscape of mountain ranges and plains

Antarctic ice sheet earthquakes shed light on ice movement and earthquakes

Antarctic ice sheet earthquakes shed light on ice movement and earthquakes

Penn State geoscientists made analysis of small, repeating earthquakes in an Antarctic ice sheet. They point that it may  lead to an understanding of glacial movement and also shed light on stick slip earthquakes like those on the San Andreas fault or in

Melting glaciers alter Earth’s gravity

Melting glaciers alter Earth’s gravity

Melting glaciers can alter Earth’s gravity field, scientists have found, a discovery that is shedding light on when Greenland and Antarctica began heavily melting. Knowing the timing of this melting could help climate scientists make better estimates of the potential

Study links ozone hole to climate change all the way to the equator

Study links ozone hole to climate change all the way to the equator

In a study to be published in the April 21st issue of Science magazine, researchers at Columbia University’s School of Engineering and Applied Science report their findings that the ozone hole, which is located over the South Pole, has affected the entire circulation

New deep-sea volcanic vents found in Antarctic’s Southern Ocean

New deep-sea volcanic vents found in Antarctic’s Southern Ocean

British researchers say the discovery of deep-sea volcanic vents in the Antarctic’s Southern Ocean suggests they’re more common than previously thought.

Deep-sea vents are hot springs on the seafloor, where mineral-rich water nourishes colonies of
