A study of the C37 alkenone distributions in core MD952011 from the Norwegian Sea (about 65°N) has allowed the evaluation of the applicability of the U37K and U37K′ indexes in these cold waters. The use of the first defined U37K appears to be the most appropriate to estimate sea surface temperatures (SST) allowing a high resolution SST reconstruction for the Holocene section. At this site, the warmest SST values were recorded during the first-half of the Holocene, between 8.5 and 5.5ka BP, after a gradual warming. Since then, the SST evolution of the late Holocene exhibits a cooling trend towards present values, in concordance with the decreasing summer insolation at these high latitudes. In terms of variability, higher SST changes were observed in the warmer than in the cooler periods, ±2°C and ±0.5°C, respectively.
