title: U-Th isotopes and Fe-Mn composition of layers from the top side of Mn nodule SO11_262DK (262GBHF)

description: Attempts have been made to study the entire growth history of a manganese nodule from the northern part of Peru Basin in the Pacific using radiochemical profiles of 230Th232Th, 227Th230Th, and 10Be9Be. Combined with the observations on Fe-Mn contents and textural variation, the radiochemical data indicate that the nodule grew more or less concentrically throughout most of its existence since it formed 1.5 my ago, receiving Mn from both bottom water and pore water. This condition appeared to have changed about 180 ky ago when the growth became asymmetric in that the top and bottom sides became fixed in their relative positions on the sea floor. Since then, the bottom side accreted with a fast rate of close to 200 mm/my, apparently fueled by the supply of diagenetically remobilized Mn in pore water from the sediment substrate. In the meantime, the top side accumulated at about 6 mm/my, a value which is in the normal range for deep-sea nodules having their Mn supplied from the hydrogenous source.

title: Major chemical elements concentration in metalliferous sediments of the southwest Pacific

description: Chemical elements in the samples analysed were determined by atomic absorption spectrophotometry after completely dissolving the samples in a mixture of hydrofluoric, nitric and perchloric acids. The chemical data were corrected for calcium interference, and the precision of the analyses was better than ± 4% at 2 s.d. for Ca, Al, Mn, Fe and Cu, ±5% for Zn, ± 14% for Ni and ±25% for Pb. Accuracy was checked by the analysis of several international standards. Samples are distributed irregularly throughout the southwest Pacific region, the major sampling being concentrated along the island arc-trench systems, and in the North and South Fiji Basins. In addition, a number of samples from near New Zealand have been included.

title: Chemical composition of manganese crusts along the Line Islands archipelago for major and trace elements

description: Thirty Mn crust samples and associated substrates were taken from dredge hauls collected at 16 sites by the Hawaii Institute of Geophysics. They are located along the Line Islands Archipelago between 15°S and 17°N, and from depths between 1150 and 4700 m. Prior to analysis, samples of both crusts and substrates were finely ground and dried over silica gel at room temperature. Following digestion in a mixture of hydrotluoric, nitric and perchloric acids, final solutions were made up in 1 M HCl and anaiysed for Mn, Fe, Ca, Al, Ti, Cu, Ni. Co, Pb and Zn on a Perkin Elmer 5000 atomic absorption spectrophotometer. Most samples were analysed in duplicate. On the basis of replicate analyses and comparison with international nodule standards (analysis by AAS), precisions for all elements were better than 4% and accuracies better than 10% for al1 elements except Al (15%). Foliowing the same procedures, samples were further analysed by inductively coupled plasma spectrophotometry for Be, Sr. Mo, V and Cd in addition to the ten elements analysed for by AAS. Whilst the precision of these analyses was excellent (better than 2%), abundances of some elements were depressed by up to 20% on ICPS with respect to AAS, probably as a result of enhanced rotational interference.

title: Rare-earth and major elements concentration in manganese nodules from the Northwest Atlantic

description: The shale-normalized REE patterns of manganese nodules from the northwest Atlantic show enrichment in Sm and Eu relative to the heavier and lighter REE, excluding Ce, and are similar to the patterns previously observed in deep water (&gt; 3000m) nodules from the Pacific. The inverse relation of this pattern to that of sea water and the high Ce anomaly (average 5.5) indicate that probably the REE in the nodules originate from sea water and the nodules are possibly hydrogenous. The patterns for micronodules are similar to those of the nodules but the concentrations of REE were substantially higher in two of them. The red clay occurring on abyssal hills where nodules and micronodules are found also shows higher REE concentrations over terrigenous gray clay. The latter is devoid of nodules and micronodules and occurs in abyssal plains. The excess REE in the red clay also show a pattern similar to those of the nodules and micronodules. Most of the micronodule samples show a lower Ce anomaly (1.7) and lower Co concentration compared to the nodules, so it is inferred that at least some micronodules were formed during post-depositional periods when the conditions were less oxidizing than average.

description: In situ Gibbs energies of reaction (DG) for acetate-oxidizing sulfate reduction, acetate-oxidizing iron reduction, and acetoclastic methanogenesis, and sulfate-reducing methanotrophy are consistently negative and relatively constant throughout most of the sediment column at the eastern equatorial Pacific Ocean Drilling Program (ODP) Site 1226. The energy yields (-DG) closely match the values (for acetate-oxidizing sulfate reduction and acetoclastic methanogenesis) in published culturing experiments with actively growing cells and, for sulfate-reducing methanotrophy, in other environments.Although microbes mediating these reactions compete for substrates, mutualistic interactions between them appear to sustain their co-existence in deep subseafloor sediments for millions of years (the interval over which the sediments have been deposited). These competing and mutualistic interactions collectively constitute a highly coupled reaction network where relative rates of reaction are regulated by the in situ Gibbs energies of reaction.

title: Stable isotope records of G. sacculifer-quadrilobatus, Mg/Ca ratios, and Mg/Ca-SST estimates of ODP Hole 184-1146A

description: The monsoon system represents one of the basic elements of global atmospheric circulation. Its evolution and variability over long periods of geologic time play a significant role in our understanding of global climate. In this study, we focus on the Late Miocene interval from 10 Ma to 6 Ma, a period of postulated profound ecological and environmental shifts in East and South Asia. The combined approach of measuring planktonic foraminiferal Mg/Ca ratios and stable oxygen isotopes from Ocean Drilling Program (ODP) Site 1146 enabled us to reconstruct temperature independent seawater delta18O (i.e. proxy for sea surface salinity) variations in order to reconstruct the hydrography in the northern South China Sea. Located offshore the Pearl (Zhujiang) River, or its predecessor, the location of ODP Site 1146 is considered to provide a most sensitive record for detecting potential changes in freshwater input/river run-off as a result of changes in continental humidity, and hence changes in East Asian summer monsoon (EASM) climate. Local seawater delta18O reconstructions reveal that monsoon development during the Late Miocene can be regarded as an abrupt weakening in the EASM around 7.5 Ma. We suggest that an EASM weakening was most likely the driving force for decreasing aridity in East and South Asia at 8-6 Ma, leading to widespread ecosystem changes in East and South Asia.
description: (1) Mg/Ca ratios were transforemd to SST by using the calibration equation for G. sacculifer of Nürnberg et al. (2000)(2) The Nürnberg et al. (2000) calibration were modified in order to account for differences in seawater Mg/Ca ratios between the Late Miocene (4.5 mol/mol) and present (5.1 mol/mol)(3) calculation of local seawater d18O; see Steinke et al. (2010)

description: 12 cores of Late Pleistocene - Holocene deposits were studied. They were collected by gravity cores on the continental slope and in the deep-water part of the Black Sea within the Adler-Tuapse polygon. In four of them in New Euxinian deposits at the base of a packet of hydrotroilite laminae paleomagnetic anomalies likely resulting from the Gothenburg magnetic excursion occur. Comparison with results of similar studies in the western Black Sea, where the Gothenburg magnetic excursion was previously found, let to validate stratigraphic synchronism of the hydrotroilite horizon in the eastern and western parts of the Black Sea and to confirm the authors' views about peculiarities of paleogeographical development of the Black Sea basin in the Late Pleistocene - Holocene.
