title: NOAA/WDS Paleoclimatology - King and Howard 2005 Southern Ocean Sediment Trap Planktonic Foraminiferal d18O Data

description: The oxygen isotopic record obtained from Globigerina bulloides, Globorotalia inflata, and Neogloboquadrina pachyderma (s.) was analysed for 5 sediment traps moored in the Southern Ocean and Southwest Pacific. The traps extend from Subtropical to the Polar Frontal environments, providing the first analysis of seasonal foraminiferal δ18O records from these latitudes. Comparison between the foraminiferal records and various equations for predicted δ18O of calcite reveals that the predicted δ18O is best captured by the equations of Epstein et al. (1953) [Epstein, S., Buchsbaum, R., Lowenstam, H.A., Urey, H.C., 1953. Revised carbonate-water isotopic temperature scale. Geological Society of America Bulletin 64, 1315–1326.] and Kim and O'Neil (1997) [Kim, S.-T., O'Neil, J.R., 1997. Equilibrium and non-equilibrium oxygen isotope effects in synthetic carbonates. Geochimica et Cosmochimica Acta 61, 3461–3475.]. The Epstein equation shows a constant offset from the δ18O of G. bulloides and N. pachyderma (s.) across the full range of latitudes. The seasonal range in δ18O values for these two species implies a near-surface habitat across all sites, while G. inflata most likely dwells at ∼ 50 m depth. A significant finding in this study was that offsets from predicted δ18O for G. bulloides do not correlate to changes in the carbonate ion concentration. This suggests that [CO32−] in and of itself may not capture the full range of carbonate chemistry conditions in the marine system. This sediment trap deployment also reveals distinct seasonal flux patterns for each species. Comparison between flux-weighted isotopic values calculated from the sediment traps and the isotopic composition of nearby surface sediments indicates that the sedimentary records retain this seasonal imprint. At the 51°S site, G. bulloides has a spring flux peak while N. pachyderma (s.) is dominated by summer production. The imprint of these differing seasonal production patterns on the flux-weighted δ18O values results in more depleted δ18O for N. pachyderma (s.) than for G. bulloides. Interpretations of N. pachyderma (s.) isotopic composition as a record of subsurface conditions may therefore need to be refined, with implications for interpretation of depleted glacial δ13C for this species (Sigman & Boyle, 2000) [Sigman, D.M., Boyle, E.A., 2000. Glacial/interglacial variations in atmospheric carbon dioxide. Nature 407, 859–869.].

title: NOAA/WDS Paleoclimatology - Lund and Curry 2006 High Resolution Florida Current Foraminferal SST Data

description: The salinity and temperature of the Florida Current are key parameters affecting the transport of heat into the North Atlantic, yet little is known about their variability on centennial timescales. Here we report replicated, high-resolution foraminiferal records of Florida Current surface hydrography for the last millennium from two coring sites, Dry Tortugas and the Great Bahama Bank. The oxygen isotopic composition of Florida Current surface water (d18Ow) near Dry Tortugas increased 0.4% during the course of the Little Ice Age (LIA) (~1200-1850 A.D.), equivalent to a salinity increase of 0.8–1.5. On the Great Bahama Bank, where surface waters are influenced by the North Atlantic subtropical gyre, d18Ow increased by 0.3% during the last 200 years. Although a portion (~0.1%) of this shift may be an artifact of anthropogenically driven changes in surface water ECO2, the remaining d18Ow signal implies a 0.4–1 increase in salinity after 200 years B.P. The simplest explanation of the d18Ow data is southward migration of the Atlantic Hadley circulation during the LIA. Scaling of the d18Ow records to salinity using the modern low-latitude d18Ow-S slope produces an unrealistic reversal in the salinity gradient between the two sites. Only if d18Ow is scaled to salinity using a high-latitude d18Ow-S slope can the records be reconciled. Variable atmospheric 14C paralleled Dry Tortugas d18Ow, suggesting that solar irradiance paced centennial-scale migration of the Inter-Tropical Convergence Zone and changes in Florida Current salinity during the last millennium.

title: NOAA/WDS Paleoclimatology - Stahle et al. 1998 Southern Oscillation Index Reconstruction

description: Exactly dated tree-ring chronologies from ENSO-sensitive regions in subtropical North America and Indonesia together register the strongest ENSO signal yet detected in tree-ring data worldwide and have been used to reconstruct the winter Southern Oscillation index (SOI) from 1706 to 1977. This reconstruction explains 53% of the variance in the instrumental winter SOI during the boreal cool season (December–February) and was verified in the time, space, and frequency domains by comparisons with independent instrumental SOI and sea surface temperature (SST) data. The large-scale SST anomaly patterns associated with ENSO in the equatorial and North Pacific during the 1879–1977 calibration period are reproduced in detail by this reconstruction. Cross-spectral analyses indicate that the reconstruction reproduces over 70% of the instrumental winter SOI variance at periods between 3.5 and 5.6 yr, and over 88% in the 4-yr frequency band. Oscillatory modes of variance identified with singular spectrum analysis at ~3.5,4.0, and 5.8 yr in both the instrumental and reconstructed series exhibit regimelike behavior over the 272-yr reconstruction. The tree-ring estimates also suggest a statistically significant increase in the interannual variability of winter SOI, more frequent cold events, and a slightly stronger sea level pressure gradient across the equatorial Pacific from the mid–nineteenth to twentieth centuries. Some of the variability in this reconstruction must be associated with background climate influences affecting the ENSO teleconnection to subtropical North America and may not arise solely from equatorial ENSO forcing. However, there is some limited independent support for the nineteenth to twentieth century changes in tropical Pacific climate identified in this reconstruction and, if substantiated, it will have important implications to the low-frequency dynamics of ENSO.
description: EXPERIMENTAL DENDROCLIMATIC RECONSTRUCTION OF THE SOUTHERN OSCILLATION  This file documents reconstruction of the winter (DJF) season of Allan's version of the Southern Oscillation Index (SOI).  It was reconstructed by using the factor scores from a Principal Components Analysis (PCA) of time t and selected t-1 and t+1 lags of 14 tree-ring chronologies from northern Mexico (Durango and Chihuahua), the southwestern U.S.A. (Arizona, Utah and New Mexico) and Java, Indonesia plus the first two factor scores from a network of 9 chronologies in OK and TX as independent variables.  All chronologies were compiled from indices of tree growth (earlywood or total ring width) detrended to remove biological trends (Cook 1985).  The dependent variable was winter (DJF) average SOI compiled by R. Allan, based on normalized Tahiti minus Darwin sea level pressure, multiplied by 10 (Allan et al. 1996), adjusted so the mean of the period 1879-1977 equals 0.0.  The reconstruction is the basis for the paper (D.W. Stahle et al. 1998).
