# Description_and_Notes
#	Description: Fiji Diploastrea cores 4F1 and LH were collected from opposite sides  of the channel in Savusavu Bay.   Core 4F1 was collected in 10 meters  of water and spans 1940 to 1997, while core LH was collected in  2 meters of water and we present here only the period 1940 to 2001.   The composite d18O and Sr/Ca records are an average of the two cores,  both normalized to the 1970-1996 mean.  Both cores were sampled at  0.5 mm intervals within the upper 50 mm, and at 1 mm intervals below  50 mm depth.

#       Abstract: To date, coral-based paleoclimate research in the Pacific has primarily  utilized core samples from the genus Porites and has been most successful  reconstructing past variability on interannual timescales, particularly  the El Nino Southern Oscillation (ENSO). The Indo-Pacific coral genus  Diploastrea, however, owing to its slower extension rate, denser structure,  and longer lifespan, can potentially preserve geochemical proxy records  2 to 3 times longer than Porites cores of the same length. Before its potential  can be realized, Diploastrea must first be calibrated and its climate signal  assessed. We present oxygen isotope (d18O) and Sr/Ca results from two  Diploastrea cores collected in Fiji (16deg 49'S, 179deg 14'E) that allow for  simultaneous evaluation of this coral's paleoclimatic utility and the  reproducibility of each tracer at this site. Comparison to a Porites record  from the same location allows for further evaluation of Diploastrea as a  paleoclimatic archive. We demonstrate that Diploastrea's septal and columellar  material yield similar d18O-SST relationships and that despite some sacrifice  of the seasonal d18O amplitude, bulk sampling of either region is satisfactory  for resolving interannual and lower frequency modes of climatic variability.  Therefore paleoclimate reconstructions employing either a septal or columellar  sampling regime of this genus may be useful at filling in spatial and temporal  sampling gaps which currently hinder the reconstruction of long-term changes  in major climate fields in the western Pacific.

#	Abstract: Progress in paleoclimatology increasingly occurs via data syntheses. 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.
