Journal of Geophysical Research - Ocean v.104 (C10) pp. 23,607-613. # Abstract: We present high-precision radiocarbon (D14C) results and stable isotope (d18O and d13C) records for a coral from Heron Island (23S, 152E) and new stable isotope (d18O and d13C) records for annual coral bands from Abraham Reef (22S, 153E) in the southern Great Barrier Reef studied earlier [Druffel and Griffin, 1993]. These tracers provide unique information on the regional water mass history, and together these data allow us to constrain the variability of circulation in the upper Pacific over the past four centuries. First, we observe decreases in d18O of coral from Abraham Reef and Heron Island, indicating an increase in sea surface temperature and/or a decrease in surface salinity since 1850. Second, the small Suess effect value (D14C decrease from 1880 to 1955, due mostly to fossil fuel CO2) observed previously at Abraham Reef [Druffel and Griffin, 1993] is confirmed in the measurements reported here from the Heron Island coral. This value is low compared to those observed in other areas of the ocean [Druffel, 1997; Druffel and Linick, 1978; Nozaki et al., 1978] between 1880 and 1955. Third, we report alterations in the correlation between El Nino events and the occurrence of low D14C, which is indicative of long-term change(s) in circulation in the SW Pacific. The D14C shifts reported here are not large, but even small temporal changes in prebomb D14C suggest that important changes in the large-scale state of the ocean have occurred, such as a temporal change in circulation. #-------------------- # Publication # Authors: Druffel, E.R.M.; Griffin, S. # Published_Date_or_Year: 1995 # Published_Title: Regional variability of surface ocean radiocarbon from southern great barrier reef corals. # Journal_Name: Radiocarbon # Volume: 37 # Edition: # Issue: # Pages: 517-524 # DOI: # Online_Resource: # Full_Citation: Druffel, E.R.M. and S.

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: Abraham Reef, Great Barrier Reef, Australia # Location: Australia/New Zealand>Australia # Country: Australia # Northernmost_Latitude: -22.096667 # Southernmost_Latitude: -22.096667 # Easternmost_Longitude: 152.492621 # Westernmost_Longitude: 152.492621 # Elevation: -10 m #------------------ # Data_Collection # Collection_Name: 99aust02a # Earliest_Year: 1635 # Most_Recent_Year: 1991 # Time_Unit: y_ad # Core_Length: # Notes: {"database":"LMR"} Abraham core-1 Collected December 1985 by Peter Isdale.
