Expanding Our Vision Brings the Big Picture Into Focus
1500 feet above the ground surface is where our suite of instruments normally operates, but for this flight we are taking them up higher, much higher, in fact over 20 times our normal range to 33,000 feet. Our flight plan is to repeat lines surveyed in a previous years by NASA’s Land, Vegetation Ice Sensor…

The Story at Ronne
Named after Edith Ronne, the first American woman to set foot on this southern continent, the Ronne Ice Shelf is tucked just to the East of the Antarctic Peninsula on the backside of the Transantarctic Mountains. With an area measured at 422,000 square kms, this is the second largest ice shelf in Antarctica. This vast…

The ‘Skinny’ on Antarctic Sea Ice
One piece of our IceBridge mission focuses on sea ice here in the south. Sea ice in the northern regions has been reducing at dramatic rates over the last decade, setting a new record just this year, but the story in the south is not so clear. In fact, there has been a buzz that…

A Recovery Mission
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…

Hiron Point in Sundarban
We traveled by boat to the south part of the Sundarbans near the Indian Ocean to install a GPS at Hiron Point, this isolated facility also hosts a tide gauge recording long-term water level changes due to rising sea level and land subsidence. Our GPS will help distinguish how much of each there is in…

Polder 32
Polder 32 is one of the many inland islands in Bangladesh that was enclosed by an embankment to protect it from flooding. When that embankment failed during Cyclone Aila in 2009, the island was flooded for almost 2 years. Subsidence of the ground inside the embankment with no sedimentation to compensate made it worse. We…

Columbia-PepsiCo Collaboration Creates Tool for Calculating Carbon Footprints
Researchers at the Earth Institute’s Lenfest Center for Sustainable Energy working in collaboration with PepsiCo, Inc. have developed new software that rapidly calculates the carbon footprints of thousands of products simultaneously.
By studying thousands of buildings and analyzing their electricity use, Columbia Climate School Dean Alexis Abramson has been able to uncover ways to significantly cut energy consumption and emissions. Watch the Video: “Engineering a Cooler Future Through Smarter Buildings“
