The site of the deployment was selected during an ice reconnaissance survey the previous afternoon, where this particular ice floe stood out from the very thin and ponded floes in the region.\u00a0 Overnight, while other shipboard science was being performed, the 2.4 m thick floe drifted only 5 miles, and was easily located the following morning.\u00a0 By this time of the cruise, the deployment operations had become extremely efficient.\u00a0 Consequently, the entire installation from the first helicopter flight with personnel and equipment to the site, to the concluding deployment of the surface package took only 1.5 hours, while other scientists concurrently obtain ice and upper ocean measurements from the floe, and the last SAMS ice mass balance buoy was deployed.<\/p>\r\n<p>More information and photos on the deployment operation are also available at:\u00a0<a href=\"https:\/\/www.whoi.edu\/page.do?pid=67322\">https:\/\/www.whoi.edu\/page.do?pid=67322<\/a><\/p>\r\n\t\t\t\t<a href=\"https:\/\/www2.whoi.edu\/site\/itp\/wp-content\/uploads\/sites\/92\/2019\/09\/DSCN3496_415273.jpg\" target=\"_self\" rel=\"noopener noreferrer\">\r\n\t\t\t\t<img loading=\"lazy\" src=\"https:\/\/www2.whoi.edu\/site\/itp\/wp-content\/uploads\/sites\/92\/2019\/09\/DSCN3496_415273.jpg\" alt=\"Gary Morgan and Will Ostrom auger the 10.5&quot; hole through the 2.4 m floe for deployment of ITP 30.\" height=\"2304\" width=\"3072\" title=\"DSCN3496_415273\" \/>\r\n\t\t\t\t<\/a>\r\n\t\tGary Morgan and Will Ostrom auger the 10.5&#8243; hole through the 2.4 m floe for deployment of ITP 30.
