Varve thickness was measured for the period 1998 AD-2192 BC on a long gravity core (CB06EV1) taken in 2006. An erosive turbidite eroded sediments from 1972 to 1966 AD. Correlation with instrumental data were made on the 1973 - 2005 AD only. Data are presented along an AD/BC time scale and a Varve Years time scale. Caution must be used when interpreting the section from 2192 BC to 243 AD because it was attributed to an estuarine environment that may have affected the varve formation. Chronology was supported by 137-Cs. The counting error sum for two varve counts (#1 and #2) of the same analyst was estimated as mean square error (Lotter and Lemcke, 1999) and it is equal to 4027 +/- 232 years (Table 1 of the paper). Count #2 was selected. East Lake, Cape Bounty, Melville Island, Canada: 74°53'N, 109°32'W, 32m depth, 5m asl. ABSTRACT SUPPLIED BY ORIGINATOR: A long sedimentary sequence from East Lake, Cape Bounty, Melville Island (74°55'N, 109°32'W) contains a 4200 year-long clastic varved record of paleohydrologic variations at high resolution. Sedimentary elemental geochemistry from micro X-ray fluorescence (m-XRF) and sediment fabric variability reflect changes in sediment sources and lacustrine conditions through time. The sedimentary environment progressed from marine in the mid-Holocene, to estuarian from 2195 BC to 243 AD, to fully lacustrine source after 244 AD. Correlation with local meteorological data indicates that varve thickness (VT) is positively correlated with snow depth on May 1st and negatively correlated with mean Sept-May temperatures. Our paleoclimatic reconstruction from VT series revealed high snow accumulation and warm Sept-May months before 1350 BC, and a period of low snow accumulation and cold Sept-May between 1600-1900 AD that may correspond to the Little Ice Age. The general trends of VT series from Cape Bounty are in phase with the d18O series in Agassiz Ice Cap, and in anti-phase with the VT series from Lower Murray Lake in the northeastern of Queen's Elizabeth Islands (QEI). Low mean Arctic temperatures coincide with clusters of high sediment yield events at East, Nicolay and South Sawtooth Lakes, especially during 1600-1750 AD and 1810-1910 AD. The East Lake record also exhibits the signature of the Atlantic Multidecadal Oscillation (AMO) for periods: 600-850 AD, 1400-1550 AD and 1750-1850 AD.
