Highlights Alkenone analysis on sediment core from Sermilik Fjord, SE Greenland. Reconstruction of ocean surface temperature changes of the past 100 years. Alkenones advected and represent temperature changes on nearby shelf. Warm ocean c. 1940 concurs with increased calving from Helheim Glacier Similar to observation from Disko Bay and Jakobshavn Isbrae in West Greenland. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 2 of warm subsurface waters ~ 1940 concurrent with markedly increased calving and retreat of Helheim Glacier. Our results therefore suggest that alkenone-derived SST time series from highsedimentation rate glacial fjords may provide a new approach for reconstruction of past changes of shelf water properties and variability around Greenland.
