Proposed Flight Lines

Detailed plan for P-3 flights over ice streams, outlet glaciers, and Jacobshavn in the Arctic using 150 MHz and 450 MHz radars, optimizing altitude for Tomography. Flight routes cover specific segments for data collection.

  1. Proposed Flight Lines

  2. April 07 Experiment • P-3 flights from Thule and Kangerdlussuaq • 150 MHz and 450 MHz Radars • Maximum altitude allowable • 6, 6 hour flights available with existing budget

  3. Flight Description • Each flight flown twice: 150 and 450 MHz • Flight 1 is highest priority at 450 Mhz • Each flight is between 2000 and 2500 km (roundtrip) • Flights 1 and 2 include segments over the ocean • Flight 3 should include a segment down the Sondrestrom Fjord

  4. Proposed Flight Lines • Ice Streams • Outlet Glaciers • Jacobshavn

  5. Flight Details • Flight 1 • Segment over open ocean • Repeat segment flown at 150 MHz in May 2006 • Flights at 150 and 450 MHz • Overflight of NGRIP and North East Ice Stream • Segment from GITS to Thule reflown several times for Tomography (20-30 m • Horizontal offsets) • Flight 2 • Flight of NEMES drilling site location • Flights across crevassed areas of outlet glaciers and across grounding lines • Reflight of GITs Thule segment for Tomography • Segment over open ocean • Flight at 150 and 450 MHz • Flight 3 • Open Ocean Segment down Sondrestrom Fjord • Several passes over Jacobshavn glacier with at least two segments separated • By 20 – 30 m • Flight over GRIP GISP drill sites • Outbound at 26000 ft, Return flight at 500 feet • Flights at 150 MHz and 450 MHz • Need to include Tomography segments
