Ice buoy left to its uncertain future as the ice will melt and remelt, it will drift, and perhaps this area will be subjected to crushing forces throwing up great ice ridges.

Dr. Pablo Clemente-Colon "ice fishing" off the HEALY. He has caught an Arctic boxfish. Not really. He is trying to sample "frost flowers" on the new ice which the CGC HEALY is passing through.
