Measuring Gravity From a Moving Aircraft Requires a ‘Gravi-God’!
From: Joël Dubé, Engineer/Geophysicist at Sander Geophysics, OIB P-3 Gravity Team One of the instruments used in Operation IceBridge (OIB) is an airborne gravimeter operated through a collaboration between Lamont Doherty Earth Observatory of Columbia University and Sander Geophysics of Ottawa, Canada. People from other instrument teams have been heard to call it a gravity…

Switchyard Project: New Sampling Record
On May 10, we celebrated the sampling of our 10th station yesterday. These are more stations than we were ever able to get water samples from. Because of the ongoing good weather, we will certainly get one more station today, and hopefully many more during the next couple of days. So watch the posted video and celebrate with…

Switchyard Project: Sampling Success
The past 1½ weeks have been very successful. Our team from Lamont-Doherty Earth Observatory was able to obtain water samples from eight stations, while the team from the University of Washington has already broken their all-time record of the past years of 18 stations. Today (May 7) is actually the first day we can’t fly…

Switchyard Project: Rescue Operation
Four people who tried to ski from the North Pole to Greenland got stuck on the ice and ran out of food. Since our team was out on the ice for sampling close to their location, we stopped sampling and picked them up.

Switchyard Project: It’s all about the weather
One can only imagine what kind of a pilot one has to be to fly in the arctic regions and land on sea-ice under weather conditions as we have experienced already – fog above the ice and clouds covering the area with very low visibility.

Switchyard Project: Day 1 – Alert, Alert, Alert
The first day of our operation is usually filled with a lot of work preparing and testing the instruments we brought up here, preparing the airplanes, loading our equipment into the planes, setting up the equipment in the laboratory and preparing the sampling containers. Since our operation requires drilling holes through the sea ice, we…
