A Simple Device for Retrieving Instruments or Traps Set Under Ice
Recovery of instruments or traps suspended under ice is often difficult because refreezing at the circumference of the hole decreases the hole diameter to less than trap diameter, and freezes around the attached line. Line freezing can be reduced by suspending the instrument from the center of the h...
