A survey by helicopter was conducted on August 11, 2007 to choose an icefloe between 3 and 5 m thick for deploying ITP 8.  Extremely thin and loose ice conditions substantially limited the possibilities, but on the second landing, a suitable 3.49 m icefloe was found.  After 5 flights to deliver the deployment team, apparatus and buoy, the ITP was installed after a routine 2.5 hour deployment.  At the same, the icefloe was cored and surveyed by a team of scientists from UAF.
