Researchers are using X-ray CT to analyze magnetic minerals in speleothems, which can reveal past climate conditions. The team hopes to uncover evidence of extreme weather events and improve understanding of New Zealand's climate history.
A recent study published in Science has proven that repeated and abrupt climate changes during the last ice age occurred simultaneously in South America, Southeast Asia, Europe, and Greenland. The researchers used stalactite measurements from caves and ice core samples to determine the timing of these events.
A team of researchers led by Eberhard Gischler analyzed the Blue Hole stalactite recovered in 1970, revealing concentric layers that detail climate conditions since the last ice age. The study provides new insights into paleo-environmental conditions and storm patterns.
Researchers at the University of Arizona have discovered a surprisingly diverse ecosystem of microbes living in the perpetual darkness of Kartchner Caverns, a limestone cave system. The microbes thrive on limited nutrients, including nitrogen-containing compounds, and can even harness energy from minerals dissolved in rock fissures.
Evidence from Siberian caves suggests a 1.5°C temperature rise could cause substantial permafrost thawing, releasing massive amounts of greenhouse gases into the atmosphere and damaging ecosystems and human infrastructure.
Researchers from the University of Arizona found that the same mathematical equation describing stalactite shapes also applies to icicles, regardless of size or growth conditions. The discovery provides new insights into the physics of natural formations and their underlying math.
Researchers at the Hebrew University of Jerusalem and Geological Survey of Israel developed a new method to date ancient earthquakes using cave evidence. They found evidence of earthquakes with magnitudes of 7.5 or greater occurring in the region over the last 200,000 years, but not in recent times.
Researchers developed a mathematical theory that describes the universal shape of stalactites, found in caves worldwide. The theory, based on fluid dynamics and geometry, reveals an ideal form underlying all stalactite shapes, with actual formations differing by less than 5%.
A recent study by Drs. Kaufman, Bar-Matthews, and Ayalon analyzed stalactite samples to reconstruct ancient climatic changes. The research found that the region experienced dry and cool conditions from 20,000 to 58,000 years ago, with significant rainfall fluctuations occurring after 6,000 years ago.
