title: NOAA/WDS Paleoclimatology - Wortmann et al 1999 Early Cretaceous Tethys Major-Element Data

description: Lower Cretaceous sediments are frequently characterized by a well expressed cyclicity. While the processes influencing environments above the carbonate compensation depth (CCD) are reasonably well understood, almost nothing is known about the deep ocean. Cretaceous sub-CCD sediments from the Tethys and Atlantic Oceans typically show rhythmic black/green shale successions. To gain insight into the nature of these black/green shale cycles, we performed detailed geochemical analyses (X-ray fluorescence, Rock-Eval and reactive iron analysis) on a 3 m long section of latest Aptian age. The major-element distribution of the analyzed shale sequence indicates a periodic change from a high-productivity and well-oxygenated green shale mode to a low-productivity oxygen-deficient black shale mode. It is proposed here that the preservation of organic matter was dependent on the strength of salinity-driven deepwater generation. Furthermore, the data show that the Corg content covaries with changes in the detrital composition. Therefore we hypothesize that Tethyan deepwater circulation was sensitive to changes in the monsoonal system. Time series analysis suggests that these changes are periodic in nature, although we are currently unable to prove that the dominant periodicity is related to the precession component of the Milankovitch frequencies.

title: NOAA/WDS Paleoclimatology - Diester-Haass 2004 Tasman Rise Neogene Paleoproductivity and Ice Rafting Data

description: Late Neogene sediments (11.3-1 Ma) at ODP Sites 1171 and1172 south of Tasmania are different in that (i) there is a hiatus at the more southerly Site 1171 covering the 5.23-8.7 Ma period, whereas Site 1172 shows a complete record during that interval, and (ii) coarse (up to 1000 um) sized clastic material and detrital glauconite occur at Site 1171, interpreted as ice rafted detritus from Antarctica, whereas at Site 1172 no glauconite has been found and clastic material is always smaller than 125 um, and is interpreted as eolian. Paleoproductivity as deduced from benthic foraminifers and carbonate dissolution was higher prior to 8.7 Ma than after the hiatus at Site 1171, related to the northward drift of the South Tasman Rise and increasing distance from the proto-polar front. Radiolarian opal concentrations anticorrelate with our paleoproductivity proxies. The depression in CaCO3 concentrations at 9.6-10 Ma and 10.6-11.2 Ma, and the strong dissolution, are tentatively regarded as an expression of the "carbonate crash event". The elevated productivity at Site 1171 at 5.23-4.5 Ma corresponds to a paleoproductivity maximum at Site 1172, where a sharp 3-5 fold productivity increase at 7-6.5 Ma points to the occurrence of the late Miocene "biogenic bloom event". Both these major late Miocene events, well known in the equatorial Indo-Pacific and SE Atlantic upwelling areas, have not be seen in the subantarctic before.

title: NOAA/WDS Paleoclimatology - Vostok - Deuterium Data and Temperature Reconstruction

description: During much of the Quaternary, the Earth's climate has undergone drastic changes most notably successive glacial and interglacial episodes. The past 150 kyr includes such a climatic cycle: the last interglacial, the last glacial and the present holocene interglacial. A new climatic–time series for this period has been obtained using δ18 O data from an Antarctic ice core.

title: NOAA/WDS Paleoclimatology - Byrd - Methane, del18O, and CO2 Data

description: A central issue in climate dynamics is to understand how the Northern and Southern hemispheres are coupled during climate events. The strongest of the fast temperature changes observed in Greenland (so-called Dansgaard–Oeschger events) during the last glaciation have an analogue in the temperature record from Antarctica. A comparison of the global atmospheric concentration of methane as recorded in ice cores from Antarctica and Greenland permits a determination of the phase relationship (in leads or lags) of these temperature variations. Greenland warming events around 36 and 45 kyr before present lag their Antarctic counterpart by more than 1 kyr. On average, Antarctic climate change leads that of Greenland by 1–2.5 kyr over the period 47–23 kyr before present.

title: NOAA/WDS Paleoclimatology - Okinawa Trough Oxygen Isotope and Mg/Ca-SST Data

description: Detailed deglacial and Holocene records of planktonic d18O and Mg/Ca-based sea surface temperature (SST) from the Okinawa Trough suggest that at ~18 to 17 thousand years before present (kyr B.P.), late spring/early summer SSTs were approximately 3°C cooler than today, while surface waters were up to 1 practical salinity unit saltier. These conditions are consistent with a weaker influence of the summer East Asian Monsoon (EAM) than today. The timing of suborbital SST oscillations suggests a close link with abrupt changes in the EAM and North Atlantic climate. A tropical influence, however, may have resulted in subtle decoupling between the North Atlantic and the Okinawa Trough/EAM during the deglaciation. Okinawa Trough surface water trends in the Holocene are consistent with model simulations of an inland shift of intense EAM precipitation during the middle Holocene. Millennial-scale alternations between relatively warm, salty conditions and relatively cold, fresh conditions suggest varying influence of the Kuroshio during the Holocene.

title: NOAA/WDS Paleoclimatology - Equatorial Pacific (MANOP C) during the past 26,000 years

description: Eleven sediment samples taken downcore and representing the past 26 kyr of deposition at MANOP site C (0°57.2′N, 138°57.3′W) were analyzed for lipid biomarker composition. Biomarkers of both terrestrial and marine sources of organic carbon were identified. In general, concentration profiles for these biomarkers and for total organic carbon (TOC) displayed three common stratigraphic features in the time series: (1) a maximum within the surface sediment mixed layer (≤4 ka); (2) a broad minimum extending throughout the interglacial deposit; and (3) a deep, pronounced maximum within the glacial deposit. Using the biomarker records, a simple binary mixing model is described that assesses the proportion of terrestrial to marine TOC in these sediments. Best estimates from this model suggest that ≈20% of the TOC is land-derived, introduced by long-range eolian transport, and the remainder is derived from marine productivity. The direct correlation between the records for terrestrial and marine TOC with depth in this core fits an interpretation that primary productivity at site C has been controlled by wind-driven upwelling at least over the last glacial/interglacial cycle. The biomarker records place the greatest wind strength and highest primary productivity within the time frame of 18 to 22 kyr B.P. Diagenetic effects limit our ability to ascertain directly from the biomarker records the absolute magnitude that different types of primary productivity have changed at this ocean location over the past 26 kyr.

title: NOAA/WDS Paleoclimatology - North Atlantic Plio-Pleistocene IRD and Isotope Data

description: We generated 200-500 year resolution records of oceanic processes in the North Atlantic (Ocean Drilling Program Site 983, 60°24'N, 23°38'W, 1983 meters water depth) for intervals in the latest Pliocene (1.86-1.93 Ma) and the earliest Pleistocene (1.75-1.83 Ma) in order to examine the linkages between millennial-scale variations in the ocean and background glacial-interglacial climate change. Within glacial intervals we find evidence for variations similar to those observed in the late Pleistocene. We find discrete ice-rafted debris (IRD) events that reoccur every 2-5 kyr. These events are preceded by a short cooling and accompanied by a reorganization of glacial deep waters. The timing of IRD events in the late Pliocene and early Pleistocene intervals is similar to that of Dansgaard-Oeschger cycles, but we find no IRD events comparable in timing to late Pleistocene Heinrich events. Although interglacial intervals are much more stable, we do find evidence for low-amplitude variations in deep water properties that reoccur every ~2 kyr within interglacial intervals. The similarity between our late Pliocene-early Pleistocene records and late Pleistocene records implies that the mechanism driving millennial-scale variations cannot be uniquely attributed to the strongly nonlinear linkage between climate and insolation and the large ice sheets of the late Pleistocene.
