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. #-------------------- # Publication # Authors: Bagnato, S.; Linsley, B.K.; Howe, S.S.; Wellington, G.M.; Salinger, J. # Published_Date_or_Year: 2004 # Published_Title: Evaluating the use of the massive coral Diploastrea heliopora for paleoclimate reconstruction. # Journal_Name: Paleoceanography # Volume: 19 # Edition: # Issue: PA1032 # Pages: # DOI: 10.1029/2003PA000935 # Online_Resource: # Full_Citation: Bagnato, S., B.K.

Geochemistry, Geophysics, Geosystems, Vol. 6, Q06001, 1 June 2005. doi:10.1029/2004GC000879 # 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. #------------------ # 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 # Funding_Agency_Name: # Grant: #------------------ # Funding_Agency_Name: National Science Foundation # Grant:AGS-1304263 # Funding_Agency_Name: National Oceanic and Atmospheric Administration # Grant:NA14OAR4310176 #------------------ # Site_Information # Site_Name: Savusavu Bay, Fiji # Location: Ocean>Pacific Ocean>South Pacific Ocean>Polynesia>Fiji # Country: Fiji # Northernmost_Latitude: -16.82 # Southernmost_Latitude: -16.82 # Easternmost_Longitude: 179.23 # Westernmost_Longitude: 179.23 # Elevation: -2 m #------------------ # Data_Collection # Collection_Name: 04fiji01b # Earliest_Year: 1940 # Most_Recent_Year: 2000 # Time_Unit: y_ad # Core_Length: # Notes: {"database":"LMR"} Composite of cores LH and 4F1 #------------------ # Species # Species_Name: Diploastrea heliopora # Common_Name: #------------------ # Chronology: # # # # # # # # #---------------- # Variables # # Data variables follow that are preceded by "##" in columns one and two. # Data line variables format: Variables list, one per line, shortname-tab-longname-tab-longname components (9 components: what, material, error, units, seasonality, archive, detail, method, C or N for Character or Numeric data) # ##age age, , ,years AD, , Corals and Sclerosponges, , ,N ##d18O_anom delta 18 Oxygen anomaly, Diploastrea heliopora, , permil VPDB, , Corals and Sclerosponges, average of the two cores both normalized to the 1970-1996 mean, ,N ##Sr/Ca_anom Strontium/Calcium anomaly, Diploastrea heliopora, , mmol/mol, , Corals and Sclerosponges, average of the two cores both normalized to the 1970-1996 mean, ,N # #---------------- # Data: # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header # Missing Values: NAN # age d18O_anom Sr/Ca_anom 2000 -0.13 -0.1 1999 0.03 0.01 1998 0.36 -0.01 1997 0.22 0 1996 -0.14 -0.04 1995 0.05 0.04 1994 0.15 0.03 1993 0.12 0.07 1992 0.06 -0.01 1991 0 -0.02 1990 -0.13 -0.03 1989 -0.26 -0.06 1988 -0.09 -0.04 1987 0.29 0.06 1986 0.12 0.02 1985 -0.05 0.01 1984 -0.02 -0.01 1983 0.21 0.03 1982 0.03 0.03 1981 0.01 0.04 1980 0.09 0.03 1979 -0.01 0.01 1978 0.06 0 1977 0.05 0 1976 -0.15 -0.02 1975 -0.21 -0.02 1974 -0.15 -0.04 1973 0.01 -0.01 1972 -0.05 -0.01 1971 -0.1 -0.03 1970 0.12 -0.04 1969 0.16 0.04 1968 -0.06 0.03 1967 0.02 0 1966 0.12 0.03 1965 0.16 -0.01 1964 0.14 -0.02 1963 0.02 NAN 1962 -0.03 NAN 1961 -0.06 NAN 1960 -0.08 NAN 1959 0.07 NAN 1958 0.26 NAN 1957 0.01 NAN 1956 -0.17 NAN 1955 -0.16 NAN 1954 0.02 NAN 1953 0.13 NAN 1952 0.03 NAN 1951 -0.07 NAN 1950 -0.12 NAN 1949 -0.1 NAN 1948 -0.08 NAN 1947 -0.06 NAN 1946 -0.01 NAN 1945 -0.02 NAN 1944 -0.2 NAN 1943 -0.11 NAN 1942 0.11 NAN 1941 0.15 NAN 1940 0.13 NAN
