Two types of instrument packages for monitoring the ice drilling process have been designed. Both are mounted in the drill and return information to the surface while drilling. One was used on a hot water during the November-December 1987 summer season in Antarctica. It was powered and controlled from the surface with the data conversion being done using a commercial board in a Compaq computer. The other design was tested in Greenland during June, 1988. It is battery powered and the data conversion is done by a custom microprocessor and electronics package mounted in an ice coring drill. The data is then returned to the surface serially over two data lines The designs and types of data collected are discussed as well as possible future extensions of the design to include controlling some of the drilling process.
