The sedimentary record is dated with tephrochronology, alleviating marine 14C reservoir age uncertainties. Comparison of changes in SSTs on the North Icelandic Shelf with variations in the atmospheric circulation above Greenland, North American Atlantic coastal SSTs, and mean temperature anomalies for the Northern Hemisphere suggests synchronous North Atlantic-wide fluctuations, which would seem to imply a common forcing factor. A positive and significant correlation between our SST record from the North Icelandic Shelf and reconstructed solar irradiance, together with modeling results, supports the hypothesis that solar forcing is an important constituent of natural climate variability in the northern North Atlantic region. #---------------------- # Science Keywords: PAGES 2k Network, PAGES Arctic 2k, Arctic 2k, temperature, decadal resolution #-------------------- # Site Name # Region: North Atlantic # Country: North Icelandic Shelf # Northmost Latitude: 66.55 # Southmost Latitude: 66.55 # Eastmost Longitute: -17.37 # Westmost Longitute: -17.37 # Elevation: 0 #------------------ # Data Collection # Core Name: MD99-2275 # First Year: -36.079 # Last Year: 1948.69 # Time Unit: AD #------------------ # Searchable Controlled Keywords # >paleocean>reconstruction>Sea Surface Temperature (C) #---------------- # Variables # age_AD Age (years AD) # sst Sea Surface Temperature (C) # age_AD sst 1948.69 6.0705 1943.44 6.8495 1935.56 7.0073 1930.31 7.3879 1922.43 5.8513 1909.3 6.5327 1896.17 6.5746 1883.04 7.4927 1869.92 7.1984 1856.79 7.0789 1843.66 5.5579 1830.53 6.5524 1817.4 6.3 1804.27 7.3933 1791.15 7.0554 1778.02 7.2154 1764.89 5.7278 1751.76 7.3543 1738.63 7.2757 1725.5 7.0237 1712.37 7.0936 1699.25 7.8395 1686.12 7.0945 1672.99 6.5663 1659.86 7.2932 1646.73 6.7329 1633.6 6.4874 1620.47 6.6389 1607.35 6.1653 1594.22 6.9067 1581.09 6.993 1567.96 6.9085 1554.83 6.7351 1541.7 6.9503 1528.58 7.0301 1515.45 6.6508 1502.32 6.7056 1489.19 6.6986 1476.5 7.608 1464.83 6.1022 1453.17 6.9607 1441.5 6.8487 1429.83 7.0327 1418.17 6.3605 1404.5 6.858 1386.17 6.719 1367.83 6.0741 1349.5 6.6948 1331.17 6.2925 1312.83 6.8942 1290.91 7.1933 1260.61 7.0332 1230.3 7.4312 1200 7.6023 1169.7 7.3866 1139.39 7.0919 1109.09 7.0426 1083.57 6.4842 1060.1 7.6362 1036.63 6.7832 1013.16 7.114 989.694 7.6157 966.225 7.7419 942.755 7.3443 919.286 7.6977 895.816 6.9998 877.041 6.2986 862.014 7.472 835.396 7.8746 808.777 6.8239 782.158 6.395 755.54 7.5316 728.921 7.7732 702.302 7.423 675.683 6.7734 649.065 6.964 622.446 7.4861 595.827 8.1686 569.209 7.789 542.59 7.8874 515.971 7.6365 489.353 7.5636 462.734 8.5481 436.115 7.6091 409.496 7.1479 382.878 7.6675 356.259 7.8094 329.64 8.051 303.022 7.8018 276.403 7.0808 249.784 6.9199 223.166 7.7717 196.547 7.5475 169.928 7.7576 143.309 7.6982 117.225 7.428 91.674 7.021 66.123 7.289 40.573 8.1268 15.022 7.9264 -10.529 7.4397 -36.079 7.4236
