The Lamont Icepod team is a blended mix of engineers and scientists learning from each other through the design and testing of this new instrument. With a range of talents and backgrounds, the project mixes seasoned field workers with those new to field work; experienced instrument developers with those newly learning this end of engineering; and scientists with countless hours spent pouring over Greenland ice sheet data with those exploring the ice sheet for the first time. It is the opportunity for mentoring and development that comes from this mix that has made the Icepod Instrument Development Project a good fit for its American Recovery and Reinvestment Act funding.
When we left Stratton Air Field almost two weeks ago, I recall smiling when a mechanical issue temporarily pulled us from the aircraft and the woman shepherding us back into the waiting area remarked, “Don’t worry, we keep doing it until we get it right!” Today we are faced with just that type of day.
Holidays vary around the world with their dates and traditions, so it should have come as no surprise that we would find a holiday in our scheduled Greenland visit. Today, April 26, is “Store Bededag,” which translates as “Great Prayer Day,” brought by the Danish to Greenland when they ventured to this island from their homeland.
Ice sheets are large enough that they can create their own weather. Large mountains of ice several miles thick, they stretch into higher elevations and gather the clouds around them. The sunny but cold weather (-21 to -9 degrees C) is a tease to the group ready each morning and waiting for clearance, day after day.
Ravens dominate the Kangerlussuaq landscape. Perhaps it is their deep ebony color and solid frame, or perhaps it is the white stillness of winter with little else but humans moving about, but whatever the cause the ravens are a recognized presence. The towering black hill rising above the glacially carved fjord is aptly named Raven Hill and boasts a steady circling of the mythical black winged creatures calling out in their raspy voices. With ravens being much a part of the region, it seems only fitting that our first flight would be to Raven Camp.
Icepod joined the first large wave of science teams headed to Greenland via the NYANG LC130 transport system. Four LC130 aircraft were packed to bursting with pallets of equipment, supplies and science teams anxious to get to their designated research locations.
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.
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.
Greenland is surrounded by a ring of high mountains that work like fingers encircling the ice to hold it in place. Ice sliding from between these “fingers” into the surrounding waters results in a major human impact – Sea Level Rise.
To Norse mythology Midgard is a place that is impassable, surrounded by a world of ocean. Thor, the hammer-wielding warrior god often traveled across to Midgard, and one imagines evidence of his fiery power remains in the highly charged rocks that are left behind. Magnetized rocks containing Thor’s energy and the fiery touch of his [...]
