When we sat down to map out the flight plan, our request to the crew for locating lakes met with an easy nod: No problem at all. It took only seconds to register that our definition of lakes might differ from theirs.
Even the most skilled of English language lipreaders are only able to tease apart about 30 percent of the information being shared, I read in a recent article. The author, herself deaf, noted that in some transmissions, the information capture is higher, while in others, nothing is collected. An average of 30 percent information transfer…most of us seek more information, we are curious beings. I don’t know anyone who is happy to sit comfortably saying “yes we know 30 percent, that is good enough.”
A new study in the journal Nature provides fresh insight into deep-earth processes driving apart huge sections of the earth’s crust. This rifting mostly takes place on seabeds, but can be seen in a few places on land—nowhere more visibly than in the Afar region of northern Ethiopia.
Can shifting tides trigger earthquakes? Research done by Maya Tolstoy, a geophysicist at Lamont-Doherty Earth Observatory, suggests they do.
Why should society care that CO2 is now as high as 400 ppm? The reasons are multiple, but all trace back to the relationship between CO2 and temperature.
Twice humans have witnessed the wasting of snow and ice from Peru’s tallest volcano, Nevado Coropuna—In the waning of the last ice age, some 12,000 years ago, and today, as industrial carbon dioxide in the air raises temperatures again. As in the past, Coropuna’s retreating glaciers figure prominently in the lives of people below. In an ongoing project, scientists at Columba University’s Lamont-Doherty Earth Observatory and partner institutions are reconstructing the ebb and flow of ice on Coropuna since the last ice age to understand how the tropics influence the global climate system,…
Lamont-Doherty scientist Hugh Ducklow is featured in a documentary due out next summer on climate change and the West Antarctic Peninsula. Catch a preview in this newly-released trailer.
Our team spent most of Friday on the Arctic sea ice, drilling and sampling ice cores at our main field site. For each core collected, Lamont-Doherty Earth Observatory scientists Andy Juhl and Craig Aumack take a number of different physical, chemical and biological measurements
Fieldwork is exciting and inspiring, leading scientists to new ideas, places and observations about how the world works. Spring on Alaska’s North Slope provides an especially productive environment for fieldwork. When the sun never sets, it’s easy to linger in the field and the lab long into the well-lit night.
While I arrived in Barrow, Alaska on Tuesday, Lamont-Doherty Earth Observatory scientists Andy Juhl and Craig Aumack, and graduate student Kyle Kinzler from Arizona State University, got here one week ago.
Andy Juhl and Craig Aumack, microbiologists from Columbia University’s Lamont-Doherty Earth Observatory, are spending a month in Barrow, Alaska studying algae in and below sea ice, and how our warming climate may impact these important organisms.
