Proposed Flight Lines

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

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

Proposed Flight Lines

1. Ice Streams2. Outlet Glaciers3. Jacobshavn

Flight DetailsFlight 1

Segment over open oceanRepeat segment flown at 150 MHz in May 2006Flights at 150 and 450 MHzOverflight of NGRIP and North East Ice StreamSegment from GITS to Thule reflown several times for Tomography (20-30 m

Horizontal offsets)Flight 2

Flight of NEMES drilling site locationFlights across crevassed areas of outlet glaciers and across grounding linesReflight of GITs Thule segment for TomographySegment over open oceanFlight at 150 and 450 MHz

Flight 3Open Ocean Segment down Sondrestrom FjordSeveral passes over Jacobshavn glacier with at least two segments separated

By 20 – 30 mFlight over GRIP GISP drill sitesOutbound at 26000 ft, Return flight at 500 feetFlights at 150 MHz and 450 MHzNeed to include Tomography segments
