USGS Deep Logging Winch

Description

In PY 2014, the United States Geological Survey (USGS) gifted its 4 km logging winch to IDP for continued use by the polar logging community. The winch has been used extensively for logging boreholes in both Greenland and Antarctica and was most recently used during the 2014-2015 Antarctic season for logging the WDC06A borehole at WAIS Divide that was drilled by the DISC Drill. Gary Clow, the former predominant operator of the winch, has trained the IDP staff on the set-up, operation, crating, maintainance and troubleshooting of the winch.

The USGS winch is capable of logging boreholes 4400 meters deep. The cable is a standard four-conductor logging cable headed with a standard 1-inch outer-diameter Gearhart-Owen variant. The winch has a broadband slip-ring connector enabling it to transmit both analog and high speed digital signals from DC to 250 MHz.
