Caves of Ice: The Next Frontier in Paleoclimatology?

It’s early June in the Austrian Alps. Tourists in shorts sweat their way up a trail from the cable car above Lake Hallstatt. But the summer heat doesn’t stop a group of scientists from pulling on brightly colored jumpsuits over their hiking clothes at the entrance to Mammuthohle, one of the many limestone caves that riddle the Dachstein Massif. Lukas Plan, a geophysicist at the University of Vienna, straps on his headlamp and pauses to warn the crowd of researchers about the cave they are about to enter. It won’t just be chilly inside, he cautions; it will be an Alpine meat locker.

The crowd, part of the fourth international ice cave workshop organized by a network of European geophysicists and glaciologists, is gathered to visit the cave’s year-round ice formations.

Plan turns toward the tunnel in the mountainside and opens the metal door. A rush of wind bursts out. The group prepares to enter, hoping to read the history of the region’s climate in the cave’s ice.

Big science at the table

José Ordovas sips a mint tea in a languid café in Madrid, Spain. His eyes scan two mobile phones as he confirms his next appointments. In conversation, he switches effortlessly between Spanish and English to find the right expressions. If the geneticist seems to be moving on a different wavelength from the other patrons, he could blame it on the jet lag: he has just flown from Boston where it’s now 5am. This is his third overseas trip this month, but Ordovas contends his frequent visits from Tufts University, where he’s based, to Europe have no adverse effects. “For me the time difference doesn’t matter, I’m up at 4am to make calls to Europe when I’m home anyway, and then I’m up late on calls to California,” he says.

Ordovas embodies the hustle and bustle of the ‘big science’ approach that has changed nutrition research in the past decade. This field, once confined to small groups of researchers studying the effects of single nutrients — such as particular vitamins or proteins — on a few dozen volunteers, is now adopting the heavy-lifting tools developed for genetics and pharmaceutical research. It also has a catchy name: nutrigenomics. And the more that researchers learn how our genes interact with our diet, the more they appreciate the deeper insight gained by an interdisciplinary approach. Such knowledge could lead to breakthroughs in our understanding of risk factors for diabetes and cardiovascular disease or, for example, improve the design of weight-loss diets.

Winter in the Picos de Europa

CUMC2010coverfrontThe snow under my tentatively placed left boot gave way and I scampered back onto my perch. I leaned heavily on my ice axe with one hand and cheerlessly on the snow with my other hand. I pawed the snowy slope like a misguided rhinoceros charging up the wrong mountain. When I hazarded a look at my leg, I noted a dismaying gap between its boot and crampon. Continue reading Winter in the Picos de Europa

Iceland Reporting Trip Roundup

I went to Iceland in April to report on volcano monitoring during the Eyjafjallajökull eruption for Science Magazine.

That story, which appeared 23 April 2010, is here.

A pair of photos from my field trips appeared in my aunt’s Long Island newspapers (L&M Publications) the week of 26 April. See them here.

A first-person essay on the visit appeared in Global Talent, a Catalan science website, on 4 May, here.

Another feature, including two of my photographs, appeared in the Financial Times Weekend Magazine on 22 May, here.

A news item appeared in Discover Magazine in the September issue, here.
