Abstract:

Over the past 13 kyr the most significant natural changes in the Reykjanes ridge region took place within 13-7.8 kyr B.P. They resulted from alternating intensifications of the influence of the Labrador (LWM) and Norwegian-Greenland (NGWM) water masses. During 13-11.7 kyr B.P. natural conditions were governed by influence of LWM with sea surface temperature (SST) 3-5°C lower present one. During 11.7-10.3 kyr B.P. NGWM with SST 6-7°C lower present one predominated. During 10.3-9.5 kyr B.P. oceanographic conditions were rapidly transforming and approaching present ones controlled by interaction between LWM and North Atlantic water masses; SST abruptly increased almost to the present value. During 9.5-8.3 kyr B.P. intensification of NGWM led to small decrease of SST (1.5-2.5°C below present value; between 8.3 and 7.8 kyr B.P. natural conditions had approximated present ones and later on remained relatively stable; SST fluctuated with an amplitude of about 1.5°C.
