title: NOAA/WDS Paleoclimatology - Sikes and Sicre 2002 C37 Alkenone, Salinity, and Temperature Data

description: This study assesses the relationship to salinity and temperature of the levels of the tetra-unsaturated 37-carbon methyl alkenone (C37:4) in the surface ocean. UK′37, a measure of the relative abundances of the C37:2 and the C37:3 alkenones, has a well constrained linear relationship to temperature in the open ocean [Prahl and Wakeham, 1987] and is a well-established technique for estimating past sea surface temperatures in the sediments (e.g. [Müller et al., 1998]). Unlike the di- and tri-unsaturated C37 alkenones, the temperature response of the tetra-unsaturated C37 alkenone is less certain [Sikes et al., 1997], and recent work has suggested a relationship to salinity instead [Rosell-Melé, 1998; Schulz et al., 2000]. Our study examined 106 surface water and sediment trap samples from the Atlantic, Pacific, and Southern Oceans to assess the relationship of the relative abundance of C37:4 to temperature and salinity. We also examined the relative unsaturation of C37:2 and C37:3 (the parameter UK′37) to the same parameters to place the C37:4 results in context. UK′37 has a strong correlation to salinity in the Atlantic, but the relationship does not hold worldwide, whereas UK′37 shows a strong linear relationship to temperatures in all ocean basins as shown in previous calibrations. The salinity response in the Atlantic does not confirm cause and effect and interpretation of the broader data set suggests any correlation is an artifact of the strong correlation of salinity to temperature in this basin implying salinity has no effect on the unsaturation of the C37:2 or C37:3 alkenones. The C37:4 alkenone shows no discernable relationship to temperature or salinity across the several basins, even when correlations are restricted to cooler temperatures where the tetra-unsaturated alkenone would be expected to be present. These results indicate that C37:4 alkenone levels in the open ocean do not reflect either salinity levels or temperature but respond most strongly to some other environmental variable, perhaps changes in growth rate, light, or nutrient supply as suggested by culture studies.

title: NOAA/WDS Paleoclimatology - Fehrenbacher et al. 2006 Western Tropical Atlantic LGM Foraminiferal Mg/Ca Data

description: We explore using changes in planktonic foraminiferal Mg/Ca with water depth in a single region to infer relative changes in deep water carbonate chemistry. The Mg/Ca ratio in foraminiferal calcite is quantitatively lowered by dissolution. We exploit this dissolution effect to generate a profile of carbonate ion concentration (CO32−) for the deep waters of the tropical Atlantic during the Last Glacial Maximum. We generated Mg/Ca data for three species, G. ruber, G. sacculifer, and N. dutertrei, from three cores located along a depth transect (2.8 to 4.0 km) on the Ceara Rise in the western equatorial Atlantic. We attribute lower Mg/Ca in glacial intervals from the shallow core to changes in sea surface temperature (SST). The even lower glacial Mg/Ca values in the deeper cores are attributed to dissolution and are used to reconstruct a paleo-CO32− profile. Our down core Mg/Ca data for G. ruber and G. sacculifer confirm that these species are more resistant to Mg loss due to dissolution than N. dutertrei. The greater susceptibility of N. dutertrei's Mg content to dissolution limits the utility of this species in thermocline temperature reconstructions to cores above the lysocline but, significant to this study, makes N. dutertrei useful in quantifying changes in deep water CO32−. Our paleo-CO32− reconstruction based on N. dutertrei suggests the Last Glacial Maximum CO32− gradient in the Atlantic was much steeper than today, implying that the boundary between deepwater masses in the Atlantic was shallower during the Last Glacial Maximum. Our results suggest comparison of Mg/Ca from multiple cores from one region could similarly provide constraints on changes in carbonate chemistry in other basins and other time periods.

title: NOAA/WDS Paleoclimatology - Kyrgyzstan Ostracode 9,000 Year Trace Element and Stable Isotope Data

description: The stable isotope and trace element geochemistry of ostracode shells from Lake Issyk-Kul, Kyrgyzstan, provide an important new paleoclimate record for central Asia. The d18O, d13C, Sr/Ca, Mg/Ca and U/Ca composition of shells from the species Candona neglecta found in two piston cores constrains the paleohydrology of the lake from 8700 to 1000 calendar yr before present. These data, combined with robust chronologies based on 16 AMS 14C dates, suggest that the region went from a relatively moist climate in the early Holocene to a more arid climate in the late Holocene. Intense freshwater input, presumably glacial runoff, flowed into the lake from 8700 to 8300 cal yr BP as evident from the d18O and d13C values. From 8300 to 6900 cal yr BP d18O and Sr/Ca values indicate that the lake was relatively fresh and an open basin, and U/Ca values suggest that the lake was well-mixed with well-oxygenated bottom waters. There is a transition zone between 6900 and 4900 cal yr BP when d18O and Sr/Ca values rapidly increase and Mg/Ca and U/Ca values rapidly decrease. During this period the lake evolved from an open, freshwater, well-mixed lake to a closed, more saline, less well-mixed lake. For the remainder of the record d18O, Sr/Ca, Mg/Ca and U/Ca are relatively constant, implying conditions similar to modern conditions, although the slight increasing trend in Sr/Ca may suggest an increase in salinity over this period. The d13C values were approximately in equilibrium with atmospheric CO2 in the early part of the record but became relatively negative in the later part of the record. This indicates that the dominant mechanism controlling the isotopic composition of dissolved inorganic carbon shifted from exchange with the atmosphere to variations in biological productivity.

title: NOAA/WDS Paleoclimatology - Southern Ocean Midlatitude 160KYr Alkenone SST Reconstructions

description: Late Quaternary climate fluctuated between extremes of glaciations, lasting ~90 kyr on average, and interglacial episodes, lasting ~10 kyr. Still largely unknown are the spatial and temporal evolution of these global climate states, with vigorous debate still underway on the mechanisms responsible for glacial inceptions and terminations. Though it is widely believed that the Southern Hemisphere oceans play a central role in global climate changes, few paleoclimate records exist from there. Here we present three new alkenone-derived SST records from the midlatitude Southern Hemisphere spanning the last 160 kyr, a full glacial-interglacial cycle. Our subtropical SST records from the last glacial period are characterized by (1) warming 47-23 kyr B.P., when high latitudes in both hemispheres cooled, and (2) milder temperatures during the penultimate glacial period than during the last glacial interval. These SST features are found to be of tropical- to subtropical-wide extent, implying increased thermal gradients at times of high-latitude ice sheet growth. This has implications for the vigor of atmospheric and upper ocean circulation and the transport of heat and moisture to the poles that may have been instrumental in the growth and maintenance of polar ice sheets during glacial periods.

title: NOAA/WDS Paleoclimatology - Istorvet Ice Cap, East Greenland Late Holocene Radiocarbon Ages

description: The Greenland Ice Sheet is undergoing dynamic changes that will have global implications if they continue into the future. In this regard, an understanding of how the ice sheet responded to past climate changes affords a baseline for anticipating future behavior. Small, independent ice caps adjacent to the Greenland Ice Sheet (hereinafter called "local ice caps") are sensitive indicators of the response of Greenland ice-marginal zones to climate change. Therefore, we reconstructed late Holocene ice-marginal fluctuations of the local Istorvet ice cap in east Greenland, using radiocarbon dates of subfossil plants, 10Be dates of surface boulders, and analyses of sediment cores from both threshold and control lakes. During the last termination, the Istorvet ice cap had retreated close to its maximum Holocene position by ~11,730 cal yr BP. Radiocarbon dates of subfossil plants exposed by recent recession of the ice margin indicate that the Istorvet cap was smaller than at present from AD 200 to AD 1025. Sediments from a threshold lake show no glacial input until the ice cap advanced to within 365 m of its Holocene maximum position by ~AD 1150. Thereafter the ice cap remained at or close to this position until at least AD 1660. The timing of this, the most extensive of the Holocene, expansion is similar to that recorded at some glaciers in the Alps and in southern Alaska. However, in contrast to these other regions, the expansion in east Greenland at AD 1150 appears to have been very close to, if not at, a maximum Holocene value. Comparison of the Istorvet ice-cap fluctuations with Holocene glacier extents in Southern Hemisphere middle-to-high latitude locations on the Antarctic Peninsula and in the Andes and the Southern Alps suggests an out-of-phase relationship. If correct, this pattern supports the hypothesis that a bipolar see-saw of oceanic and/or atmospheric circulation during the Holocene produced asynchronous glacier response at some localities in the two polar hemispheres.

title: NOAA/WDS Paleoclimatology - Vaks et al. 2003 Ma'ale Efrayim Cave, Israel Speleothem Stable Isotope Data

description: High-resolution 230Th/234U ages and d18O and d13C compositions of speleothems 
in Ma'ale Efrayim Cave located to the east of the central mountain ridge of Israel 
enable us to examine the nature of the rain shadow aridity during glacial and 
interglacial intervals. Speleothem growth occurred during marine glacial 
isotopic periods, with no growth during the two last marine isotope interglacial 
intervals and during the peak of the Last Glacial Maximum. This contrasts 
with speleothem growth in caves located on the western flank of the central 
mountain ridge, in the Eastern Mediterranean semiarid climatic zone, which 
continued throughout the last 240,000 yr. Thus, during glacial periods water 
reached both sides of the central mountain ridge. A comparison of the present-day 
rain and cave water isotopic compositions and amounts at the Ma'ale Efrayim Cave 
site with those on the western flank shows that evaporation and higher temperatures 
on the eastern flank are major influences on isotopic composition and the 
lack of rainfall. The d18O and d13C profiles of the speleothems deposited 
between 67,000 and 25,000 yr B.P. match the general trends of the isotopic 
profiles of Soreq Cave speleothems, suggesting a similar source (eastern 
Mediterranean Sea) and similar climatic conditions. Thus, during glacial periods 
the desert boundary effectively migrated further south or east from its present-day 
location on the eastern flank, whereas interglacial periods appear to have been 
similar to the present, with the desert boundary at the same position. The decrease 
in overall temperature and a consequent reduction in the evaporation to precipitation 
ratios on the eastern flank are viewed as the major factors controlling the decay 
of the rain shadow effect during glacial periods.
