A log of the temperature of the fluids in the borehole; a differential temperature log records the rate of change in temperature with depth and is sensitive to very small changes. Using empirical models, we relate this radar- attenuation pattern to borehole- measured temperature to then infer the temperature structure of this ice sheet. The temperature distribution through the Greenland ice sheet at the Dye 3 borehole is a record of the past climatic changes in the Arctic. Scientists measure the temperature of an ice sheet directly by lowering a thermometer into the borehole that was drilled to retrieve the ice core. The most detailed information exists since 1850, when methodical thermometer- based records began. temperature drilling parameters. refrigerator temperature log sheet. A team of scientists and engineers has for the first time successfully drilled over two kilometers through the ice sheet in West Antarctica using hot water. Consequently the variations of the ice sheet sur- face temperature ( 15Ts) might be not merely proportional to those of the inversion temperature ( • Ti) as it was suggested by Jouzel et at. Once they reached the bottom of the ice sheet to the sediment below , BEAMISH team members sent various instruments down through the bore hole to record ice temperature, water pressure to. ocean borehole temperatures, cave deposits, ice cores, lake sediments, , fossils glacier length.

The project - named BEAMISH ( Bed Access, Monitoring and Ice Sheet History) - will see a string of instruments fed through the borehole to record water pressure, ice temperature, and deformations. The borehole temperature reconstruction does not match the last bit of this time period in part because the measurements begin further down the hole, and many of the measurements were made in the 1980s and 1990s before the instrumental record ends. On 1 July 1993, after five years of drilling, the Greenland Ice Sheet Project Two ( GISP2, ). length of the environmental record, presence or lack of discontinuities), the only such experiment of this magnitude in ice core research. temperature scenarios to ﬁnd the best ﬁt with the borehole temperature record.

The method is in principle the same as that used by Alley and KociFig. A team of scientists and engineers has for the first time successfully drilled over two kilometres through the ice sheet in West Antarctica using hot water. the borehole which will record.
