My involvement with Operation IceBridge comes from a desire to better understand the polar climate and the climatic changes that are evident there. I have been working with NASA through the last five years as a system engineer for the Constellation project, while working to complete my doctoral dissertation in Aerospace Engineering Sciences at the University of Colorado in Boulder. I have also been recently involved with airborne remote sensing and LiDAR systems by completing a three year, NASA-funded research campaign that involved flying a small Mooney M20K aircraft to the Northwest Territories, Canada to better understand noctilucent clouds through synchronized observations with NASA’s Aeronomy of Ice in the Mesosphere (AIM) satellite.
This has been my first campaign with the project, participating in sorties based out of Kangerlussuaq, Greenland throughout the first two weeks of May 2010. To me, the project is a unique synthesis of personal interests — from polar climate observation and analysis, aircraft operations, remote sensing and instrument design, and flight research campaign planning. My role this year has been principally as a student with the intent to integrate the data that we collect with satellite and ground station data to better characterize glacial evolution, though I hope to become much more involved with the operations of future campaigns.
Seeing Eastern Greenland for the first time through the P-3’s windows, as its four engines lifting the aircraft easily over the sharp mountainous ridgelines and its strong airframe holding up to the constant moderate turbulence of the coastal winds being channeled through the fjords, was spectacular. I really got a strong sense of contrast between experiencing the stark minimalism of the ice cap and experiencing the aggressive terrain of the eastern fjordlands. The long flight trajectories we conducted there gave me a sense of the incredible diversity of the terrain and the low altitude of the flight plans gave me a connection to the environment not available at higher altitudes, even down to viewing the tracks of polar bears!
I have been very grateful to all the team members that have spent time with me to explain in detail the systems that they are responsible for, specifically the LiDAR systems, the photogrammetric systems, and the RADAR systems. Also, NASA pilot Shane Dover clearly explained to me the systems unique to the P-3 from a pilot perspective, which was of keen interest even though I may never log an hour in a P-3. In particular interest to me was the way John Sonntag was able to modulate complex flight plans onto ILS frequencies, providing the pilot a very logical, precise display to aid in navigating through both the numerous winding glaciers and the long swaths of satellite groundtrack. This has truly been an amazing personal experience, but upon hearing the excitement that many of the world’s top glaciologists have voiced about Operation IceBridge during my time in Kangerlussuaq, I’ve been proud to be a part of the team.
