 note = {P(論文), An electronic data collection and control system has been developed for the PICO 13.2cm deep ice coring drill. It monitors a variety of drilling parameters including inclination, depth, temperature, pressure, RPM, weight and others. It also displays this data for the drill operator and allows the operator to control speed and direction of the drill motor. The display program allows setting limits on all parameters so an alarm sounds if anything goes wrong. This instrumentation package will be described and some of the data collected with it will be discussed.},
