High-resolution alkenone sea surface temperature variability
on the North Icelandic Shelf: implications for Nordic Seas
palaeoclimatic development during the Holocene.

doi:10.1177/0959683607073269
The palaeoceanography of the northern Icelandic Shelf for the
Holocene period was reconstructed from alkenone indices measured
in core JR51-GC35. This contains a continuous record of Holocene
sedimentation spanning 0 - 10.2 cal. kyr BP with a resolution of
~20 yr/cm. We have identified a general Holocene cooling trend
that has superimposed millennial-scale oscillations of >2°C.
Their timing is in close agreement with the timing of glacier
advances in northern Iceland. For the later half of the Holocene,
the alkenone-sea surface temperature (SST) record from JR51-GC35
correlates with proxy data for the strength of NADW formation
recorded in cores south of Iceland. This is interpreted as
evidence of a close connection existing between north Icelandic
sea surface temperatures and the North Atlantic meridonal
overturning circulation. The timing of the millennial-scale
SST variability in our core off North Iceland is found to be
out of phase, or anti-phased, with the SST variability of a
record in the eastern Nordic Seas (MD952011). This suggests
that the evolution of Holocene climate in the Nordic Seas
was more complex than previously proposed; and it is likely
to be caused by differential responses of the Irminger and
Norwegian Currents and modulated by changes in atmospheric
circulation analogous to the North Atlantic Oscillation.
STUDY NOTES: Uk37' alkenone content and alkenone sea surface temperature
estimates for the Holocene from Core JR51GC-35, Iceland Shelf,
North Atlantic. UK37 is converted to SST using the Rosell-Melé
et al. (1995) annual SST calibration that is constructed from
an extensive data set of NE Atlantic and Nordic Seas core-tops.
