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…

“The glacier whispers to me”
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…

What can we learn from ‘land terminating’ glaciers?
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…

Greenland’s ‘Big Three’ Glaciers
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…

Triaging the Behindedness
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…

Earthquake Chasers in Upstate New York
Following a series of small, mysterious earthquakes in the rural town of Berne, southwest of Albany, N.Y., seismologists from Lamont-Doherty Earth Observatory have placed three temporary seismometers in the area, in an attempt to understand what is driving the tremors and assess whether there is a risk of larger events. Occasional small quakes have been recorded…

Seismologists Gather for “Discourse over Materials”
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…

Challenges Inherent in Teaching Geosciences
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…
