Core of the Matter

A final note (for now) on the expedition to recover ice cores from the top of Puncak Jaya in Papua, Indonesia: the cores arrived safely on Thursday, July 22, at Ohio State University’s Byrd Polar Research Center, and are now in a special freezer. In coming months, the team hopes to extract and interpret climatic… read more

Ice on Ice

I have reached Jakarta, and so have the ice cores, which are being kept frozen while awaiting air shipment to the United States. The rest of the team has already returned to their homes. Next for me: back to sea level, on two research cruises that will add oceanographic information to the data we gathered on Puncak Jaya…. read more

Images of Ice Drilling

Here are some photos of the ice drilling, and the site where we are working. All come courtesy of David Christenson, Greg Chmura and Ario Samudro, the video/photography team from Freeport McMoRan, which has been helping us with all phases of logistics.

The Landscape We Are Up Against

We have drilled a second core through the ice to bedrock, and are done at our first site. Unfortunately, the helicopter that we need to move the heavy pieces to our second planned spot is down for regular maintenance until next Monday, June 21. That means the team must wait it out at the relatively sheltered “saddle… read more

Ice Drills Retrieved

With the drills essential to our work apparently lost somewhere in transit, Lonnie and I finally backtracked to Jakarta–a five-hour flight–and found them sitting in an airline warehouse! Within 24 hours, we had them shipped to our staging site, and now we are ready to go.

High Elevation Lakes

We are currently taking samples of water and sediments from high-elevation lakes near the glaciers. Like ice cores from the glaciers themselves, these should contain substances that will help us understand the climate history of this region. The sampling is being done in conjunction with the Indonesian Institute of Sciences and the Indonesian Meteorological, Climatological… read more

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… read more

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… read more
