Summary
Abstract: The DC-8 Dropsonde System (D8D) uses dropwinsonde and Global
Positioning System (GPS) receivers to measure the atmospheric state
parameters (temp, humidity, windspeed/direction pressure) and location
in 3 dimensional space during the sonde's descent once each half
second. Measurements are transmitted to the aircraft from the time of
release until impact with the ocean's surface.

GPR > Ground Penetrating Radar Ancillary Description
Quality Error in the measurements arises from three main sources: * the migration technique (See Processing Steps (http://nsidc.org/data/docs/agdc/nsidc0274_conway/index.html#process...).) * uncertainty picking the location of the bed reflection * uncertainty in the radio wave velocity within the glacier. For these measurements the investigators estimate the uncertainty in ice thickness to be approximately 5 m.
