Bruce Vaughn of INSTARR (Institute of Arctic and Alpine Research, University of Colorado) is leading the way in monitoring the melting of our polar ice caps with an apparatus that his organization has built to monitor the flow for water isotopes in ice cores.
Dimetix DLS-C15 lasers monitor roll diameter and width
INSTARR has developed an apparatus that includes a Dimetix DLS-BH30 laser distance sensor with an integrated heater. The laser sensor is mounted inside a temperature controlled freezer operating at -40 degrees F. The distance sensor measures the relative distance change to the top of a plunger resting on a sample of Arctic ice. The distance calculation is included in the parameters that determine the melt rate of the ice isotopes.
