They are about 250 m apart, from Ras Umm Sidd, off the southern Sinai co ast, in the northern Red Sea proper. The correlation coefficients between fom coral 8 18 0 records from Ras Umm Sidd vary on an annual time scale. The two additional 8 18 0 records were obtained previously from two other colonies (RUS-95, Felis 1999, and RUS-l, Pätzold and Klein, unpublished data), which grew in the same environment about 500 m away. Therefore, we suggest that local biological (individual) effects play a maj or role in the coral 8 18 0 records. As a test, we correlate the different 8 18 0 records with the eOADS sea-surface temperature (at al1l1Ual time scales and four time intervals, 1907-1916, 1919-1939, 1946-1966 and 1976-1992). The correlation coefficients are also different among the different 8 18 0 records and eOADS SST on annual time scales. Excluding the data gaps, the correlation coefficients varied from -0,45 (RUS-95) to -0.60 (RUS-93a). A 3-coral average composite Ö 18 0 re cord was constructed from 1907- 1992. Regression analysis between annual SST and this 3-coral average 8 18 0 re cord yields a much better and significant correlation (r=-0.68) also excluding the data gaps. Therefore, based on this study, it is advisable to analyse more than one coral from a given locality to obtain a reliable coral 8 18 0 record that can be used in coral-based paleoclimate studies. The Ö I8 0/SST gradient varied between 0.15 to 0.18%%e, with a mean value of 0.165%ofOe as in a previous study by Felis (1999). The 8 18 0 record of RUS-93a indicates a warming in the twentieth century of about 1.1 oe. Pronounced cyclicities of 10 and 3.6 years are evident when cross-spectral analysis is applied to the bimonthly 8 18 0 time series of RUS-93a and RUS-93b. The 3.6-year period is coherent with a similar cyclicity in the Southern Oscillation Index (SOl). Also, a highly coherent 5.8 cyclicity is evident. This period is also present in the 8 18 0 of RUS-95 (Felis 1999), and happens to be the most prominent period in the co-spectrum of the Northern Atlantic Oscillation (NAO) and EI-Nino Southern Oscillation (ENSO). #------------------ # Authors: Anderson, D.M., Tardif, R., Horlick, K., Erb, M.P., Hakim, G.J., Noone, D., Perkins, W.A., and E.

We describe additions to a collection prepared for use in paleoclimate state estimation, specifically the Last Millennium Reanalysis (LMR). The 2290 additional series include 2152 tree ring chronologies and 138 other series. They supplement the collection used previously and together form a database titled LMRdb 1.0.0. The additional data draws from lake core, ice core, coral, speleothem, and tree ring archives, using published data primarily from the NOAA Paleoclimatology archive and a set of tree ring width chronologies standardized from raw International Tree Ring Data Bank ring width series. In contrast to many previous paleo compilations, the data were not selected (screened) on the basis of their environmental correlation, multi-century length, or other attributes. The inclusion of proxies sensitive to moisture and other environmental variables expands their use in data assimilation. A preliminary calibration using linear regression with mean annual temperature reveals characteristics of the proxy series and their relationship to temperature, as well as the noise and error characteristics of the records. The additional records are structured as individual files in the NOAA Paleoclimatology format and archived at NOAA Paleoclimatology (Anderson et al. 2018) and will continue to be improved and expanded as part of the LMR Project. The additions represent a four-fold increase in the number of records available for assimilation, provide expanded geographic coverage, and add additional proxy variables. Applications include data assimilation, proxy system model development, and paleoclimate reconstruction using climate field reconstruction and other methods. #------------------ # Funding_Agency #
