title: (Table 1) Age determination of ODP Hole 117-723A

description: During the last ice age, the Indian Ocean southwest monsoon exhibited abrupt changes that were closely correlated with millennial-scale climate events in the North Atlantic region (Overpeck et al., 1996, doi:10.1007/BF00211619; Schulz et al., 1998, doi:10.1038/31750; Altabet et al., 2002, doi:10.1038/415159a), suggesting a mechanistic link. In the Holocene epoch, which had a more stable climate, the amplitude of abrupt changes in North Atlantic climate was much smaller, and it has been unclear whether these changes are related to monsoon variability. Here we present a continuous record of centennial-scale monsoon variability throughout the Holocene from rapidly accumulating and minimally bioturbated sediments in the anoxic Arabian Sea. Our monsoon proxy record reveals several intervals of weak summer monsoon that coincide with cold periods documented in the North Atlantic region (Bond et al., 2001, doi:10.1126/science.1065680) -including the most recent climate changes from the Medieval Warm Period to the Little Ice Age and then to the present. We therefore suggest that the link between North Atlantic climate and the Asian monsoon is a persistent aspect of global climate.

title: (Table T1) Carbon composition and biogenic silica of ODP Hole 199-1221C sediments

description: The Paleocene/Eocene (P/E) boundary, at ~55 Ma, is characterized by a transient warm period lasting 10,000 yr. This interval is globally characterized by significant chemical and biological signals. Ocean Drilling Program Core 199-1221C-11X captured the P/E boundary section at a depth of 154 meters composite depth. Biogenic components of the sediment were measured across this interval in order to better define the events that occurred at the P/E boundary in the equatorial Pacific Ocean. A 26-cm interval low in CaCO3 was identified, whereas biogenic silica and organic carbon remained unchanged. Although CaCO3, biogenic silica, and organic carbon (C-org) production is controlled by different constraints, it is unlikely that an environmental factor would cease production by CaCO3-producing organisms without affecting biogenic silica or C-org production. The data indicate that the CaCO3 P/E boundary event was caused by a change in CaCO3 preservation rather than a change in CaCO3 production.

title: Depth-age points to construct the age model of ODP Site 202-1242 during the Mid-Pleistocene Transition

description: This dataset contains the tie points used to establish the age model of ODP Site 1242. The age model of ODP Site 1242 is based on graphic correlation of the high-resolution ODP 1242 benthic δ¹⁸O record to the global benthic δ¹⁸O stack of Lisiecki and Raymo (2005, LR04). The strategy used here was correlating identifiable δ¹⁸O-signatures in both the 1242 and the LR04 stack records occurring at the midpoints of glacial-interglacial-glacial transitions. We took the age of those events directly from the LR04 stack or the boundaries between marine isotopic stages defined by Lisiecki and Raymo (2005).

title: Stable oxygen isotope data of Globigerinoides ruber white and titanium intensity from sediment core GeoB6211-2

description: The South American summer monsoon (SASM) is the main source of precipitation for the most densely populated and agriculturally productive regions of tropical and subtropical South America. Here we investigate the impact of the Atlantic Multidecadal Oscillation (AMO) on the SASM using ~4500 yr long proxy records of the discharge variability of the La Plata River Drainage Basin (PRDB), subtropical South America. We measured the stable oxygen composition of planktic foraminifera (related to the extension of the PRDB plume), and Ti intensity in bulk sediment (related to the source of the terrigenous sediments) from a marine sediment core. Spectral and wavelet analyses of our records indicate an oscillation with period of ~64 yr. We conclude that the observed oscillation reflects variability in the SASM activity associated to the AMO. Sea surface temperature and atmospheric circulation anomalies triggered by the AMO would control the variability in SASM activity.

title: Long-chain alkyl diol record from an alpine lake in southern Spain

description: This dataset includes the fractional abundances of the long-chain alkyl diol (LCD) record for the last ca. 9000 years of an alpine lake, Laguna de Río Seco (LdRS) at 3020 masl, in the Sierra Nevada (southern Spain), along with four reconstructed reference temperature time-series (from 1908 to 2008 CE at 3020 masl) used for the LCD-temperature calibration. Six main LCD isomers have been identified: C28 and C30 1,13-diols, C28 and C30 1,14-diols, and C30 and C32 1,15-diols. Four reference temperature series have been reconstructed at 3020 masl from 1) the temperature shifts between reference low elevation observatories and LdRS site: reference temperature time-series 1a (from Madrid data), and reference temperature time-series 1b (from Sevilla data), and from 2) the direct comparison between Madrid and Sevilla temperatures and those from the observatory Cetursa 5 (3020 masl, Sierra Nevada) by means of ordinary least square regressions: reference temperature time-series 2a (from Madrid data), and reference temperature time-series 2b (from Sevilla data).

title: (Table 1) Composition of selected ash layers in ODP Site 126-792

description: Glass shards from 26 megascopic tephras (1-29 cm thick) were separated and analyzed for 26 elements and 87Sr/86Sr and 143Nd/144Nd isotope ratios. The isotope data allowed us to assess the degree of alteration of the samples. The separates contain less than 10% of palagonitized glass or secondary alteration minerals. Correlation diagrams and multivariate analyses have been used to characterize the glass shards in a tectonic setting and group the tephras according to their magmatic affinity. Four tholeiitic groups, two calc-alkaline groups, and one group with glass of shoshonitic affinity can be distinguished. The tholeiitic groups form a time series; however, judging from the rare-earth-element patterns and the temporal variations of the Ce/Yb ratios, the evolution is not unidirectional from strong to weak tholeiitic affinity.The tephras have been correlated with volcanism along the Izu-Ogasawara and Ryukyu arcs by means of trace element distribution, 87Sr/86Sr ratios, and their magmatic affinity. The tholeiitic layers were derived from volcanoes on the Izu-Ogasawara Arc, most probably from the volcanic island Hachijojima. Only one group of the calc-alkaline layers can have derived from the Izu-Ogasawara Arc. The other calc-alkaline layers and the two layers with shoshonitic affinity probably derive from volcanism along the Ryukyu Arc.

title: (Table T1) Long-chain alkenones, UK'37 and derived sea surface temperatures of ODP Sites 184-1147 and 184-1148

description: A reconnaissance study of alkenone stratigraphy for the past 35 m.y. in the northern South China Sea (SCS) using sediments from Sites 1147 and 1148 of Ocean Drilling Program (ODP) Leg 184 has been completed. Alkenones were not detected in sediment samples older than ~31 Ma. However, C37:2 appeared in the sedimentary record between ~8 and 31 Ma and both C37:2 and C37:3 were present between 0 and 8 Ma. These changes in alkenone occurrences may signal a response to global-scale Neogene cooling as well as to monsoon intensification and sea level changes over time as a result of Himalayan uplift and the opening of the SCS. Alternatively, they may be related to an evolutionary record of the development of temperature control on alkenone production in coccolithophores. The Uk'37 index for 0-8 Ma produces sea-surface temperatures (SST) of 19°-26°C, which are in the range of previously determined glacial-interglacial values for the northern SCS. Before the late Pleistocene (~1.2 Ma), the SST range is between 23° and 26°C with less variation. This change in variability may signify the early stage of intensified winter monsoons where cold wind and waters from the north may not yet have had a significant effect on SST or it may be the evolutionary link between the early development of unsaturated alkenones in coccolithophores and modern temperature control of alkenone production. We believe a long-term alkenone record is useful for further understanding of global-scale neogene cooling, the development of the East Asian monsoon system, and the evolutionary development of temperature control on alkenone unsaturation. Our data indicate that a high-resolution Uk'37 record for at least the last ~8 Ma is feasible for the northern SCS.

title: (Table 2, page 1052) Palladium, iridium and gold contents of some oceanic manganese nodules

description: The abundance and distribution of palladium, iridium and gold has been determined in manganese nodules from widely varying locations and geological environments within the Atlantic, Indian and Pacific Oceans. The distribution of these metals is characterized by a lack of distinct regional variations, homogeneous distribution within an individual nodule, and a lack of any correlation with variations in major and other trace elements in the nodules. Assuming that all the iridium in the manganese nodules is of extraterrestrial origin, an upper limit on the mass accretion rate of interplanetary matter to the earth is calculated to be 60 tons/day over the surface of the earth.
description: The nodules were crushed and reduced to a 6ne powder in a ceramic mortar and irradiated for 24 hr in a nuclear reactor and converted to chlorides.From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions. At the time it was the most extended data compilation on ferromanganese deposits world wide. Initially published in a proprietary format incompatible with present day standards it was jointly decided by AWI and NOAA to transcribe this legacy data into PANGAEA. This transfer is augmented by a careful checking of the original sources when available and the encoding of ancillary information (sample description, method of analysis...) not present in the NOAA-MMS database.

title: (Table 1) Hydrogen- and carbon-isotope compositions of methane and pore water hydrogen-isotope compositions in DSDP Hole 96-618

description: Hydrogen- and carbon-isotope compositions of methane (dD-CH4 and d13C-CH4) and pore water hydrogen-isotope compositions (dD-H2O) in several samples from the uppermost 100 m of Orca Basin sediments show little variation with depth and have mean values of - 184, -73.5, and 7 per mil, respectively. The dD-CH4 is typical of that generally found in deep-sea sediments and suggests that the methane was produced biologically almost entirely via the CO2 reduction pathway. Production of small amounts of methane (-15% of the total) from acetate dissimilation cannot be completely ruled out, however. The pore water is more enriched in deuterium than present day Gulf of Mexico deep water, suggesting that the brine found at the bottom of Orca Basin was formed at a time when appreciably more isotopically light water was tied up in continental ice sheets than is at present. The d13C-CH4 values reported here are similar to previously determined brine d13C-CH4, but substantially more enriched in 13C than previously determined pore water d13C-CH4. Isotopic evidence and the decrease in interstitial salinity with depth suggest that most of the methane production within the Orca Basin system occurs in sediments deeper than about 5 m sub-bottom. Small deposits of isotopically anomalous methane occurring in near-surface sediments may be the result of spatially variable inputs of slumped material to the sediments underlying the anoxic, hypersaline brine.

title: Sedimentological, organic petrographic and organic chemical characteristics of Albian and Cenomanian/Turonian black shales from the North Altlantic (Tab. 3, 4)

description: Large parts of the Cretaceous Atlantic Ocean are characterized by the wide-spread deposition of organic-carbon-rich sediments ("black shales“), with a maximum occurrence during Aptian/Albian and Cenomanian/Turonian times. In order to explain the origin of these black shales, changes in the amount and type of organic matter in relation to changes in paleogeography, paleoceanic circulation, and paleoclimate have been investigated in detail. The study is mainly based on calculation of accumulation rates of marine and terrigenous organic carbon, organic carbon/sedimentation rate relationships, and estimates of paleoproductivity. Because both the amount and type of organic matter in the black shales change markedly with location and age, different mechanisms must have caused the accumulation of these organic-carbon-rich sediments: (1) Terrigenous organic matter supply was the dominant factor for black shale formation during Hauterivian and Albian times in the Northwest Atlantic.(2) Increased oceanic productivity was important for black shale deposition in the Northeast Atlantic during Albian times.(3) Increased preservation of (marine) organic matter in anoxic environments due to extremely reduced deep-water circulation was probably the main cause for the formation of Cenomanian/Turonian black shales, rather than increased supply of organic matter due to higher oceanic productivity.(4) Locally, rapid burial by turbidites may have been an important mechanism for increased preservation of organic matter.

title: Relative abundance of pennate diatoms Thalassionema spp. and Thalassiothrix spp. im Upper Miocene-Lower Pliocene bulk sediment at ODP Hole 145-886B, North Pacific (Table 1)

description: Rapidly deposited Thalassionema-Thalassiothrti pennate diatom oozes previously have been described in Upper Miocene-Lower Pliocene sediment beneath the frontal boundary of the eastern equatorial Pacific. Here we document a new occurrence of Thalassionema-Thalassiothrix ooze in Upper Miocene-Lower Pliocene sediment beneath the frontal boundary of the subarctic North Pacific. The ooze is a 6 m interval of siliceous sediment at Ocean Drilling Program (ODP) sites 885/886 that was rapidly deposited between approximately 5.0 and 5.9 Ma. Bulk sediment in this interval may contain greater than 85% pennate diatom tests. There are also abundant laminae and pockets that are composed entirely of Thalassionema and Thalassiothrix diatoms. The presence of a rapidly deposited ooze dominated by pennate diatoms indicates unusual past conditions in the overlying surface waters. Time coincident deposition of such oozes at two distinct frontal boundary locations of the Pacific suggests that the unusual surface water conditions were causally linked to large-scale oceanographic change. This same oceanographic change most likely involved (1) addition of nutrients to the ocean, or (2) redistribution of nutrients within the ocean. The occurrence and origin of pennate diatom oozes may be a key component to an integrative understanding of late Neogene paleoceanography and biogeochemical cycling.
