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
On Thursday we lowered a camera into an ice borehole to get a look at the underside of the ice. In the following video, you can clearly see the algae living in the bottom of the ice due to their pigments, which they use to harvest light.
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.
Otis Redding sang “you don’t miss your water ’til your well runs dry” in 1965 about pining for a lost love. Last week, Climate and Society founder and Lamont-Doherty Earth Observatory scientist Mark Cane reprised it with a much different, more literal focus: water scarcity in the 21st century.
Nicole Davi, a postdoctoral scientist at the International Research Institute for Climate and Society and the Lamont Doherty Earth Observatory, thinks tree rings are an ideal way to motivate students to collect and analyze data as well as to learn about climate change.
Recovery Glacier is a section of Antarctic ice that lies east of the peninsular arm of West Antarctica, tucked behind the Transantarctic Mountains, a dividing line that separates west from east. We know from satellite data that Recovery and its tributaries have a deep reach, stretching well inland. But there is a lot we don’t know about Recovery because the remoteness of the area has limited the number of surveys.
This month, IceBridge Antarctica resumes. The crews have spent the last few weeks in Palmdale, where the DC8 is based, for instrument installation and test flights prior to our move down to Punta Arenas, our home base for IceBridge Antarctica.
