Giant earthquakes: not as random as thought
By analyzing sediment cores from Chilean lakes, an international team of scientists discovered that giant earthquakes reoccur with relatively regular intervals. When also taking into account smaller earthquakes, the repeat ...
How glaciers disappeared from Scotland at the end of the last Ice Age
Research led by a Stirling academic has revealed how glaciers disappeared from Scotland at the end of the last Ice Age.
Ancient humans left Africa to escape drying climate
Humans migrated out of Africa as the climate shifted from wet to very dry about 60,000 years ago, according to research led by a University of Arizona geoscientist.
Geophysical investigation aims revealing how vegetation responds to climate change
In early August 2017, a team of scientists from the University of São Paulo (USP), the University of Campinas (UNICAMP) in Brazil and France's Development Research Institute (IRD) began drilling boreholes and analyzing sediment ...
Understanding the glacial history of the western Arctic
To interpret what we see today both on land and at the seabed, we need to understand how the landscape was different in the past. When we say "past," we mean on a geologic timeframe—specifically, about 10,000 to 20,000 ...
Post-glacial history of Lake of the Woods
The extent and depth of lakes in glaciated regions of North America are controlled by climate and the influence of differential isostatic rebound of the land's surface that began when Pleistocene ice melted from the continent. ...
Study finds Earth's magnetic field 'simpler than we thought'
Scientists have identified patterns in the Earth's magnetic field that evolve on the order of 1,000 years, providing new insight into how the field works and adding a measure of predictability to changes in the field not ...
Meltwater lakes under the Antarctic Ice Sheet accelerated glacial retreat in the Earth's past
During the last glacial period - when the ice in the Antarctic was far thicker and extended further offshore than it does today - it has been speculated that subglacial lakes existed beneath it. An international team of researchers ...
Coring Arctic lakes to study Vikings
Billy D'Andrea, a Lamont-Doherty Earth Observatory paleoclimatologist and Center for Climate and Life Fellow is currently doing fieldwork in Norway's Lofoten Islands. He's interested in the natural factors that may have ...
