ITP 110 Deployment

ITP 110 was the second ITP deployed during the JOIS 2018 cruise. As the previous ITP deployment, this day was another beautiful day. However, the ice was more rubbly and several floes cracked while trying to position the ship, so it took longer to find a candidate floe. Personnel go over in the aft man basket and measure two ice thicknesses of 80 and 84 cm which is sufficient for the deployment. The ship’s gangway was lowered onto the ice for access by personnel and equipment was lowered using the ship’s crane. The deployment operation takes 2 hours while others in the science party perform ice analyses.
