O12 - 02 GLOBAL CHANGES & MARINE GEOSCIENCES GROUND SURFACE TEMPERATURE VARIATIONS IN THE LAST 200 YEARS IN ROMANIA FROM INVERSION OF BOREHOLE TEMPERATURE DATA C. Demetrescu 1 M. Tumanian 1 V. Dobrica 1 C. Boroneant 2 1 Institute of Geodynamics Bucharest Romania 2 National Administration for Meteorology Bucharest Romania Summary Temperature data from eight boreholes in the orogen bordering the Transylvanian Basin (Eastern Carpathians Apuseni Mts.) have been inverted for ground surface temperature history (GSTH) in the last 200 years. The temperature measurements were obtained with a thermistor probe (sensitivity in the 0.01 K range) using the stop and
