Crew members of the USCGC Healy deploying the 12×30 L bottle CTD/rosette, beginning the 9th cast of the 26th station, located at 83°41'N, 173°48'E. Notice that all bottles are open, the sensor package underneath the bottles, and the rope hanging from the rosette that is connected to the mono corer (similar to the gravity corer), which will collect sediments from the seafloor. Photo taken on 28 August 2015 by Petty Officer 2nd Class, C.J. Mendenhall, USCG.
