Bicycle winch

One of the problems with doing science at temperatures down to minus 40 degrees is that normal equipment tends to break. The team had tried a motorised winch the year before,but it broke down. Hand winches are another alternative, but they are too slow and tiring to lower instruments hundreds of metres down into the ocean. So, the expedition came up with another alternative, a custom-built bicycle winch.
