| Zusammenfassung |
| Modelling of surface temperature change effect on temperature vs.~depth and
temperature-depth logs in Western Canada Sedimentary Basin show that SAT
(surface air temperature) forcing is the main driving factor for the
underground temperature changes diffusing with depth. It supports the
validity of the basic hypothesis of borehole temperature paleoclimatology,
namely that the ground surface temperature is systematically coupled with
the air temperature in the longer term (decades, centuries). While the
highest groundwater recharge rate used in the modelling suggests that for
this extreme case some of the observed curvature in the profile, could be
due to groundwater flow, it is more likely that the low recharge rates in
this semi-arid region would have minimal impact. We conclude that surface
temperature forcing is responsible for most of the observed anomalous
temperature profile. |
