Transylvanian ice cave reveals European winter climate record

Over the last 10,000 years, water dripping into a cave in Transylvania has frozen into one of the largest and oldest cave glaciers in the world. Today, the Scărișoara Ice Cave in central Romania preserves one of the longest ice records on Earth, a boon for climate researchers seeking to study how Europe’s climate has fluctuated during the Holocene.

Down to Earth With: Cave microbiologist Hazel Barton

In the early 1990s, when Hazel Barton was pursuing her doctorate in medical microbiology at the University of Colorado Health Sciences Center in Denver, she enjoyed exploring caves as a hobby. She never imagined that she would one day incorporate caving into her career.

Geomedia: Film: Exploring Florida's aquifers with filmmaker Tom Fitz

Filmmaker Tom Fitz describes the first time he found himself sitting, alone, more than 20 meters below Earth’s surface and about 300 meters into an underwater cave: He was waiting in position to film a sequence of divers swimming through a narrow passageway as their lights illuminated the chamber for his new, yet to be named, documentary. “I was suddenly in absolute, complete black,” Fitz says. “The kind of darkness that we rarely experience.”

Cave paintings confirm mystery European bison species

Ice-age hunters had an intimate knowledge of the animals they coexisted with — and this familiarity is clearly depicted in paintings on cave walls throughout Europe. Inside a cave in France, scientists recently identified artistic evidence dating to about 17,000 years ago of a previously unknown hybrid species of cattle crossed with bison. The paintings confirm findings from recent genetic studies of fossil bison, the researchers say.

Down to Earth With: Underwater cave explorer Jill Heinerth

Jill Heinerth has trekked farther into caves than any woman in history and logged more than 7,000 dives across every continent and up to roughly 140 meters underwater — recreational divers only reach depths up to 40 meters. She has dived inside icebergs in Antarctica, beneath the Sahara Desert, and in the turquoise waters of the Bahamas.

Cave dripwater records wildfires

Water seeps through soil and bedrock before dripping from the roof of a cave and carries with it elements of the outside world and its climate history. That is why speleothems, cave structures formed via precipitation, can be studied as climate proxies. New research suggests that the chemistry of the cave dripwater can also contain the signature of wildfires that burned outside the cave, on the ground above the cave’s roof, yielding a more complex picture of the past.

Chinese cave art reveals record of climate change

In times of drought, Dayu Cave in the Qinling Mountains of central China has remained a reliable source of water, and since at least the 16th century, thirsty visitors to the cave recorded their pilgrimages on the walls. Now the graffiti — rendered in black pigment on the yellow cave walls — is providing scientists with a unique record of how climate change affected nearby communities between 1520 and 1920.

Ancient cave art discovered in Indonesia

Europe has long been thought to have been the home of the oldest art in the world — including a stash of cave paintings in northern Spain that date to about 40,000 years ago — but a new dating technique may put Indonesia on the ancient art map as well.
