ITP 16 was the first ITP deployed for DAMOCLES in IPY, and took place in early September 2007 from the Polarstern. Scientists from the Alfred Wegener Institute for Polar and Marine Research in Germany, Shirshov Institute of Oceanology, Russia and Japan Marine-Earth Science and Technology, Japan all contributed to the deployment efforts of all of the ice based instruments during the expedition. Despite the relative thinness of the ice, the drilling became difficult at the end due to seawater that was encountered near the bottom in the porous rotten ice at end of the melt season. Some problems were encountered while lowering the wire using the winch, as the wire sometimes chafed against the spool and several times the plastic coating had to be repaired (to ensure the integrity of the inductive modem circuit). This particular ITP system was deployed in the evening between 8 PM and midnight (UTC) and the underwater profiler responded to post-deployment interrogation successfully on the second attempt.
