How the Toe of Italy’s Boot Evolved
Nano and I have arrived in the Crotone Basin, where we’re staying in a place that Italians call an “agriturismo,” which is like a bed and breakfast that also serves lunch and dinner. Our little place is unique even among agriturismos. It is called Canciumati (can-chew-ma-tea), a house with four generations living under one roof.…

Scouting the Glacier
Team members are now actively scouting by foot on Puncak Jaya, looking for the best drill spots, travel routes and campsites. The man in red is Broxton Bird of Ohio State University. In brown, the appropriately named alpine veteran Keith Mountain of the University of Louisville. At bottom: team leaders Dwi Susanto and Lonnie Thompson give a…

Recovering from Jet Lag in a Dormant Volcano
It is a brutal flight from New York City to Roma. I am a sucker for in-flight movies: things I would never watch in the real world, I am completely enthralled with during an overseas flight. The problem on this flight is that we arrive at 7:30am. We have a whole day ahead of us…

Moving Up a Melting Mountain
Four days ago, we flew into the lowland Papuan city of Timika, then moved up to Tembagapura, a town managed by the Freeport-McMoRan company, whose gold/copper mine near our glaciers is lending us logistical support. Tembagapura, at 1,900 meters (6,000 feet), was our first step in acclimatizing to high elevation. Now we have moved up…

Return to Malawi: Bringing Home Instruments and Earthquake Data
In early May, Scott Nooner and I returned to Malawi to retrieve our seismic equipment and finally lay eyes on the data recorded over the last 4 months. Picking them up was vastly easier than putting them out. In contrast to the days studying out-dated maps and driving down dirt roads looking for sites, and…

The shrinking face of Jacobshavn Isbrae (Glacier)
Jacobshavn Isbrae is one of the fastest moving and most productive glaciers in the world. Scientists estimate that close to the snout (front) its movement has accelerated in recent years from 20 to 40 meters a day. At the same time that the front has accelerated the glacier has been rapidly retreating through ‘calving’ (large sections breaking…

Heading for Thin Air
The project to core the glaciers of Puncak Jaya was officially launched today at a press conference in Jakarta, at the offices of the Indonesian Meteorology, Climatology and Geophysics Agency (BMKG). Agency director general Sri Woro B. Harijono hailed the project as “a milestone for climate study in Indonesia” that will produce important data for…

Our Race Against Time
Our team is planning to recover and analyze ice cores from glaciers on opposite sides of the tropical Pacific Ocean: Puncak Jaya in Papua-Indonesia (4,884 meters above mean sea level) and Nevado Haulcán, Peru (6,100 meters.). Puncak Jaya offers the only potential opportunity to acquire an ice core history from the western side of what…

Reaping Ice From a High Indonesian Peak
After years of preparation, scientists are about to ascend Indonesia’s 4,884-meter (16,000-foot) Puncak Jaya, earth’s highest mountain between the Andes and the Himalayas, to drill samples of some of the last, fast-dwindling glacial ice in the tropics. From deep cores representing centuries of accumulation, they hope to extract clues to past cyclic swings in the…
