Luckily the wind was to our backs as the ice thickness profiling teams began measuring ice thicknesses along the Healy s track of broken ice. We collected data for a distance of 2,060 meters today. It was not only used to transport the ice drilling equipment, but also to shuttle us back to the ship. You re driving, he shouts through my cap s earflaps and pulled up neck gaiter as he jumps on behind me. It didn t take but one ridge for me to learn that flying over them was the fun part.
Snow offers resistance to ships during their forward motion.
To account for the snow on ice, some researchers calculate equivalent ice thickness as the sum of ice thickness and half or one-third of snow depth. A better estimate of the effects of snow on ship motion can be obtained from the measured snow depths combined with the density of the snow. It s exactly like one I have in my kitchen at home. I learned that the tools used in field research do not necessary need to be high-tech or expensive. They simply must do the job.
