Observatory (IBO) consisting of an ITAC, ITBOB, and IMB on a 1.2 m thick, fairly level ice floe with some melt ponds.\u00a0 The profiler on this particular ITP was one of the first two systems outfit with prototype biosuite sensor packages, and the first deployed in the Makarov Basin (the other, on ITP 52, had been deployed in the Canada Basin a month earlier).<\/p>\r\n<p>Poor visibility and high winds hampered the deployment operations, while the Polarstern struggled to stay on station against the floe.\u00a0 While one group deployed the ITP, another group deployed the ITAC and ITBOB a safe distance away, and other scientists conducted ice measurements.\u00a0 Immediately after deployment, the deployment team was rushed from the ice due to the worsening weather so were unable to conduct the final inductive modem circuit test, but communications between the underwater and surface units proved to be fine.<\/p>\r\n<p>Photos on this page courtesy of: Sergey Pisarev, Ben Rabe, Hiroshi
