title: Weight percentages and mass accumulation rates of biogenic components in sediment core RC11-210 (Table 1)

description: High-resolution records of the concentration and mass accumulation rate (MAR, or flux) of biogenic sediments from core RC11-210 in the central equatorial Pacific are compared for the entire late Pleistocene. The fluxes of calcium carbonate and organic carbon correlate well. The opal flux pattern shows no direct correlation with the other two; rather, opal flux maxima correlate with slopes of (i.e. both precede and follow) the organic carbon and carbonate MAR peaks. Organic carbon and calcite therefore may both be better indicators of past productivity than opal, which is an indicator of transition at this location. We interpret the sequence low biogenic fluxes, high opal fluxes, high carbonate, carbon, and opal fluxes as representing the transition from low to high sea surface biological productivity. The phase relationships for eccentricity of the biogenic sedimentation records were compared to those of other climatic indications including the oxygen isotope record of ice volume, the ice core CO2 record, the Pacific delta13C record, the deep nutrient (Cd/Ca) record, and the eolian grain-size record of wind intensity. We find that starting from maximum ice volume (phase angle of 0°) the phase relationships of the 100,000-year periodicity show, in the first quadrant, maximum wind intensity (30°) and maximum calcite and carbon flux (45°) occurring first, followed by maximum opal flux (75°) and then maximum deep nutrients (95°). Minimum Pacific delta13C occurs at a phase angle of 155°, the maximum CO2 in the Vostok record and minimum ice volume is at 180°. Thus, in the eccentricity climate cycle, glacial conditions lead to stronger wind-driven circulation which enhances productivity which in turn results in enhanced oceanic and atmospheric carbon dioxide and minimum ice volume.

title: Age model of sediment core V20-120 (Table 2)

description: Time series analyses of atmospheric and oceanic variables in a late Pleistocene record from the northwest Pacific show the complex relationship of the response of various segments of the climate system to changes in the earth's orbit. Most variance spectra of time series from this subarctic record contain frequency peaks with periods corresponding to at least one of the major orbital components of eccentricity, obliquity, or precession. Although the radiolarian faunal (water mass) assemblages have prominent spectral peaks with 41,000-year periods which are coherent with obliquity at this frequency, only the Transitional faunal assemblage contains variance focused at a frequency corresponding to the 100,000-year period of eccentricity. Three of these faunal time series also show variance concentrated at a frequency with a 20,000-year period. These three time series are not coherent at a 20,000-year frequency with either of the dominant spectral peaks of precession. They are coherent, however, with variations in the second harmonic of the obliquity cycle. Changes in obliquity apparently affect siliceous faunal abundances in the northwest Pacific region of this high-latitude site more than variations in eccentricity or precession. Maxima in the time series of quartz abundance occur during low values of eccentricity and high glacial ice volume. Because atmospheric winds serve as the major source of supply of quartz to the sediments at this site, these high quartz values reflect increased aridity at the source region. Except for short periods during interglacials, the characteristics of the surface waters in this region of the subarctic Pacific during much of the last 460,000 years were similar to those which exist today in the Sea of Okhotsk. The spectrum of winter sea surface temperature estimates, derived from siliceous microfaunal abundances, contains dominant frequency peaks at periods of 100,000, 41,000, and 23,000 years which are coherent with eccentricity, obliquity, and precession, respectively. Based upon the relationship of the Subarctic Front with the dominance of specific faunal asemblages, the front was positioned south of its present-day location throughout much of the late Pleistocene.

title: (Table 1) Calculated sea surface temperature of sediment core RC11-210

description: Proxy indicators of sea surface temperature and equatorial divergence based on radiolarian assemblage data, and of trade wind intensity based on eolian grain size data show similar aspects of variability during the late Pleistocene: All indicators fluctuate at higher frequencies than the 100,000-year glacial-interglacial cycle, display reduced amplitude variations since 300,000 years ago, exhibit a change in the record character at about 300,000 years ago (the mid-Brunhes climatic event), and have higher amplitude variations in sediments 300,000-850,000 years old. Time series analyses were conducted to determine the spectral character of each record (delta18O of planktonic foraminifer, sea surface temperature values, equatorial divergence indicators, and wind intensity indicators) and to quantify interrecord coherence and phase relationships. The record was divided at the 300,000-year clear change in climatic variability (nonstationarity). The delta18O-based time scale is better lower in the core so our spectral analyses concentrated on the interval from 402,000-774,000 years. The delta18O spectra show 100,000- and 41,000-year power in the younger portion, 0-300,000 years, and 100,000-, 41,000- and 23,000-year power in the older interval, all highly coherent and in phase with the SPECMAP average stacked isotope record. Unlike the isotope record the dominant period in both the eolian grain size and equatorial divergence indicators is 31,000 years. This period is also important in the sea surface temperature signal where the dominant spectral peak is 100,000 years. The 31,000-year spectral component is coherent and in phase between the eolian and divergence records, confirming the link between atmospheric and ocean surface circulation for the first time in the paleoclimate record. Since the 31,000-year power appears in independent data sets within this core and also appears in other equatorial records [J. Imbrie personal communication, 1987], we assume it to be real and representative of both a nonlinear response to orbital forcing, possibly a combination of orbital tilt and eccentricity, and some resonance phenomenon required to amplify the response at this period so that it appears as a dominant frequency component. The mid-Brunhes climatic event is an important aspect of these records, but its cause remains unknown.

title: Calcium carbonate and stable isotope composition of sediment core RC13-110

description: Stable isotopes in benthic foraminifera from Pacific sediments are used to assess hypotheses of systematic shifts in the depth distribution of oceanic nutrients and carbon during the ice ages. The carbon isotope differences between ~1400 and ~3200 m depth in the eastern Pacific are consistently greater in glacial than interglacial maxima over the last ~370 kyr. This phenomenon of "bottom heavy" glacial nutrient distributions, which Boyle proposed as a cause of Pleistocene CO2 change, occurs primarily in the 1/100 and 1/41 kyr**-1 "Milankovitch" orbital frequency bands but appears to lack a coherent 1/23 kyr**-1 band related to orbital precession. Averaged over oxygen-isotope stages, glacial delta13C gradients from ~1400 to ~3200 m depth are 0.1 per mil greater than interglacial gradients. The range of extreme shifts is somewhat larger, 0.2 to 0.5 per mil . In both cases, these changes in Pacific delta13C distributions are much smaller than observed in shorter records from the North Atlantic. This may be too small to be a dominant cause of atmospheric pCO2 change, unless current models underestimate the sensitivity of pCO2 to nutrient redistributions. This dampening of Pacific relative to Atlantic delta13C depth gradient favors a North Atlantic origin of the phenomenon, although local variations of Pacific intermediate water masses can not be excluded at present.

title: Calculated sea surface temperatures for the last glacial maximum

description: SST (1-12) is estimated mean annual Sea Surface Temperature in degrees C at the LGM depth. SST res is the difference between the LGM temperature estimate from this core, and the core-top estimate made with the same faunal transfer function, in the grid box overlying the site. This gridded core-top value is used because some cores with LGM samples do not have corresponding core-top analyses. A modern transfer-function estimate is used, rather than an atlas value, to minimize regional biases in the difference calculation associated with regional residuals in the transfer function. Negative values of LGM-MOD reflect cooling relative to modern conditions. Positive values reflect warming. Estimates are reported here for latitudes -40 to 40. Note, however, that only values from latitudes -20 to 20 were used in the final reconstruction. This is because no cores from higher latitudes were used in the definition of the faunal factors -- thus we consider estimates outside of the tropical latitudes to be suspect.
