Earth Institute research expeditions investigating the dynamics of the planet on all levels take place on every continent and every ocean. Most projects originate with our main research center, Lamont-Doherty Earth Observatory, and are often run in collaboration with other institutions.

IcePod Clears Hurdles and Takes to the Air

The morning briefing room was filled with layers of engineers and technicians from the civilian side, matched with pilots, navigators and air support staff from the Air National Guard side. Spanning the middle were the two Systems Project Office (S.P.O.) representatives. Adding new instrumentation and equipment to any aircraft requires intense scrutiny, but on a military plane there are extra rounds of reviews and sign offs required.

Welcoming a New Instrument for ‘Probing’ the Polar Regions

The new Common Science Support Pod (CSSP) Ice Imaging System for Monitoring Changing Ice Sheets (IcePod) instrument designed by Lamont's Polar Geophysics Group.

In 2009 it was just a dream. But creative vision, sweat equity, good partnerships and funding can bring dreams to reality, and 2013 delivered. It was four years ago that a small team of Lamont scientists, polar geophysicist Robin Bell, engineer Nick Frearson and ocean climate physicist Chris Zappa, began discussions of an instrument that could be used to collect measurements on polar ice during routine field-support flights in both the Arctic and Antarctic. It’s called the IcePod.

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

by | 11.8.2012 at 3:53pm
Travel to the Ronne Ice Shelf involved passing by the Ellesworth Mountains. The range contains Antarctica’s highest peak, Vinson Massif at 4897 meters of elevation.

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 know about Recovery because the remoteness of the area has limited the number of surveys.

Launching the Season with a Key Mission – IceBridge Antarctica 2012

Snow blowing off the ice

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.

Earth Institute scientists explore how the physical world works on every continent — over and under the arctic ice, in the grasslands of Mongolia, on volcanoes in Patagonia, over subduction zones in Papua New Guinea, and on the streets of New York City.
