ITP 109 Deployment

The final ITP deployed during JOIS 2918 was ITP 109 on an overcast, but otherwise decent day.  The area has more open water between apparently thinner floes than the previous ice stations.  The first floe that the ship attempts to moor to breaks up when the ship approached it, but the second floe holds together.  The rear manbasket is used to lower a team to survey the ice which is found to be sufficient for the deployment (74 cm).  The deployment took about 1.5 hours while ice analyses were also performed by others in the science party at the same time.
