  • “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…

    A Rare 114-Year Record, Kept by Generations, Logs Changing Climate

  • 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…

  • Code Charlie Turns to Code Delta

    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…

AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
