The Russian MI-8 helicopter was brought to the Barneo runway after breakfast loaded with all of the buoys and deployment apparatus and departed with 8 deployment personnel at 9:50 UTC. One and a half hours and 273 km further upstream from Barneo a large ice floe greater than 250 m in diameter and surrounded by 1-2 m ridges was selected for the deployment site. No rafting was detected during test drilling which indicated ice thicknesses between 1.6 m and 2.0 m with 0.1 m freeboard and 0.2 m of snow on the surface.<\/p>\n<p>Unloading of the helicopter, deployment of all 4 buoys (in air temperatures hovering around 30\u00b0C), and reloading of the deployment apparatus was completed in 6 hours while the helicopter remained on site. By 19:50 UTC all personnel and apparatus had returned safely at the Barneo ice camp.<\/p>\n\t\t\t\t<a href=\"https:\/\/www2.whoi.edu\/site\/itp\/wp-content\/uploads\/sites\/92\/2024\/02\/DSCN9686-scaled.jpg\" target=\"_self\" rel=\"noopener\">\n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/itp\/wp-content\/uploads\/sites\/92\/2024\/02\/DSCN9686-scaled.jpg\" alt=\"Assembling the Tripod for AOFB deployment with MI-8 in the background.
