% ----------------------------------------------------------------------- % WAIS divide Borehole temperature record % as measured in January 2009 % data represent the average between duplicates or triplicates when available. % Calibration has been determined with a Steinhart-Hart curve: % 1/T = a0 + a1*ln(R) + a3*ln(R)^3 % a0 = 0.003090925 % a1 = 3.0623e-04 % a2 = -5.6090e-07 % Accuracy of calibration is within 0.2K % First column is depth below the surface, in meters % Second column is the resistance measured in 2009 in KOhms % Third column is the borehole temperature in degrees C, measured in 2009 % Pooled standard deviation is 2.0mK under 20 meters in 2009 (13 depths) % Any questions should be addressed to Anais Orsi, aorsi@ucsd.edu % Anais Orsi, April 2009 % This dataset was published in %Orsi, A.
