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… read more

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… read more

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… read more

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 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

Having seen the Russell glacier from the air (May 13, 2010 blog post), several of us decided to travel the 35 miles by land from our Kangerlussuaq station with a local guide named Adam. Adam is from Southern Greenland and fills us in on local information. He notes in that area it is illegal to… read more

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… read more

Nature is keeping us in check at every turn. With weather and volcanic ash clouds limiting visibility we have to regularly rearrange plans, but most days we are able to capture a fairly complete set of data.The flight over Russell Glacier in Southwest Greenland (just inland from Kanger) was a redirect from a mission aborted… read more

Today’s flight had to be carefully planned in order to avoid the volcanic ash plume still drifting  from  Iceland, so we flew to the east coast of Greenland to survey the Helheim glacier first. Glaciologists refer to Helheim glacier as one of ‘The big three’ in Greenland. The ‘big three’ (Helheim, Jakobshavn/Ilulissat and Kangerdlussuaq) are among… read more

Last fall, Lamont-Doherty Earth Observatory, honored my former advisor and boss, Bill Ryan. As my small contribution, I offered this essay that ends with a story about Bill. “Triage” is a term originating with medical personnel in the military. Its original meaning was the process of dividing wounded on the battlefield into three groups: those… read more

Every Friday afternoon, for as long as anyone can remember, the seismologists at Lamont-Doherty Earth Observatory have gathered for a lively session of discourse over materials. “Discourse over materials” is a phrase coined by scholars who use ethnographic techniques to study the behavior of scientists and science students as though they (we) were a recently-contacted… read more

Several inherent attributes of ocean, atmosphere and solid earth sciences contribute to making these disciplines challenging to teach and learn at the K-14 level. These include the large spatial scale of important processes, the consequent reliance on models and representations rather than actual target phenomena in hands-on activities, the centrality of systems thinking and emergent… read more

Since the first week of the Spring Campaign we have had a planned flight from Thule to Fairbanks. This trans Arctic flight will provide a valuable overview of the icecap and the condition of the Northwest Passage. The weather has caused reschedules in that flight until we are down to the last days of the… read more

The United Nations has awarded Taro Takahashi, a geochemist at Lamont-Doherty Earth Observatory, its highest honor for environmental leadership, the Champions of the Earth award, for his research on the oceans’ uptake of carbon dioxide and its implications for global warming. He was presented with a trophy and a $40,000 prize on Thursday, April 22,… read more
