Ice trials on USCGC HEALY during April/May 2000
Ice trials on the new USCGC Healy were conducted in Baffin Bay in April/May 2000. IMD's main contribution was to measure the sea ice properties, specifically ice thickness and strength. These were done using two pieces of equipment, an Over-The-Side-Video (OTSV) and a RapidCore. The OTSV is a d...

From the video screen, which had been calibrated, the thickness of the ice was measured. The RapidCore is an apparatus that allows an ice core to be retrieved without anybody going onto the sea ice. It is lifted by crane from the deck of the ship onto the ice and it then drills a core up to 1.5 m thick, controlled from the ship. After drilling, the RapidCore was crane lifted back onto the deck, the core retrieved and measurements of core temperature, density, and salinity were made. From these measurements, the ice strength was determined for correlation with the full-scale tests. Thick sections of some cores were returned to IMD for analysis of the crystal structure.
