title: Bulk chemical composition of pelagic sediment samples from the Central Pacific Basin, GH 79-1 detailed survey area

description: Sediment samples from three box cores and one piston core, collected on cruise GH79-1 of the research vessel Hakurei-Maru, were analyzed for major oxides and minor elements. All cores were collected from a small area of the Central Pacific Ocean, centered at 167°40'W and 10°N. The concentrations of 10 elements (Si, Al, Fe, Mg, Ca, Na, K, Ti, P, and Mn) were determined for 15 bulk sediment samples using X-ray fluorescence. Between the four sites, compositional ratios exhibit a longitudinal trend. This east-west trend in the composition of the ISF may be related to a decreasing influence of continentally derived material from east to west. The ISF at DOMES Site C, the easternmost of these four locations, most closely resembles the composition of terrigenous mud. An increase in the relative contribution of basaltic debris, from east to west, may be one factor contributing to the relative increases of Fe2O3, MgO, CaO, and TiO2 and the decrease in total alkalies along this same trend.

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.This dataset represents the digitized Table XVI-1, pp. 231 of the related publication.

title: Chemical analysis of major constituents in surface sediment samples from GH79-1 cruise

description: Surface sediments were collected during the GH79-1 cruise, Geological Survey of Japan, from the area of 10°-13°N and 165°-180°W. Material for this study (34 samples) was selected from box core samples. The samples examined were mainly of an argillaceous or calcareous-argillaceous type. They were dried at 110°C, ground, and subsequently split into fractions. One fraction was analysed with automatic X-ray fluorescence spectrometer JOEL-IOOS for Si, Ti, Al, Fe, Mn, Mg, Ca, Na, K, and P. Other fractions were analysed for total water, ignition loss, dissolved chlorine, ferrous iron, and carbonate.

title: Chemical composition of manganese nodules from GH80-1 cruise

description: 67 samples of manganese nodules were obtained during the GH79-1 Cruise of R/V Hakurei Maru in the northern part of the Central Pacific Basin. All nodules were immersed in running water and then ion-free water. After air-dried, samples were ground to under 150 mesh. The ground samples were encased in small paper bags, dried at 20-25°C for 24 hours, and then kept in a desiccator. In most cases an analysis was done for mixed ground sample of two or three different size classes of nodules from each box corer or freefall grab. Mn, Fe, Ni, Cu, Co. Pb, and Zn were determined by atomic absorption spectrometry. Each sample of 0.1 g was decomposed with a mixture of 5 ml of hydrochloric acid and 5 ml of nitric acid in a covered 50 ml beaker on a boiling water bath for about 30 minutes. After cooling, the solution was filtered into a 100 ml calibrated flask and diluted to the mark with water. The atomic absorbance of each element in the sample solution was measured using an atomic absorption spectrometer using an air-acetylene flame.

title: (Table 1) Mineralogy of basal sediments from DSDP Hole 25-245

description: Deep Sea Drilling Hole 245 (31°32'S, 52°18'E) in the southwest Indian Ocean shows pronounced linear concentration-depth gradients in interstitial dissolved Ca, Mg and Sr. Electrical conductivity tests enable us to make the estimate of a constant diffusion coefficient with depth of about 0.000002 cm**2/sec. The shapes of the concentration-depth gradients suggest that the major reaction sites in this hole are situated in the basal sediments and/or underlying basalts. It is proposed that observed interstitial water concentration changes in Ca and Mg are related to alteration of basaltic material, whereas those in Sr are due to calcium carbonate recrystallization processes. Support for the basaltic material alteration hypothesis comes from petrochemical and mineralogical data. Geochemical data also indicate that the high contents in Fe and Mn of the basal sediments can be related to low temperature alteration of basaltic glass and not necessarily to 'hydrothermal' activity.

title: Aboveground community and species-specific plant biomass from the Jena Experiment (Dominance Experiment, year 2010)

description: This data set contains aboveground community plant biomass (Sown plant community, Weed plant community, Dead plant material, and Unidentified plant material; all measured in biomass as dry weight) and species-specific biomass from the sown species of the dominance experiment plots of a large grassland biodiversity experiment (the Jena Experiment; see further details below). In the dominance experiment, 206 grassland plots of 3.5 x 3.5 m were established from a pool of 9 plant species that can be dominant in semi-natural grassland communities of the study region. In May 2002, varying numbers of plant species from this species pool were sown into the plots to create a gradient of plant species richness (1, 2, 3, 4, 6, and 9 species). Plots were maintained by bi-annual weeding and mowing. Plot size was reduced to 1.0 x 1.0 m in 2009. Aboveground community biomass was harvested twice in May and August 2010 on all experimental plots of the dominance experiment. This was done by clipping the vegetation at 3 cm above ground in one rectangle of 0.2 x 0.5 m in the center of each experimental plot. The harvested biomass was sorted into categories: individual species for the sown plant species, weed plant species (species not sown at the particular plot), detached dead plant material, and remaining plant material that could not be assigned to any category. All biomass was dried to constant weight (70°C, &gt;= 48 h) and weighed. Sown plant community biomass was calculated as the sum of the biomass of the individual sown species. Overall, analyses of the community biomass data have identified species richness and the presence of particular species as an important driver of a positive biodiversity-productivity relationship.

title: (Table S1) Stable carbon and oxygen isotopes and Mg/Ca ratios of planktonic foraminifera from ODP Hole 198-1209B

description: The Paleocene-Eocene Thermal Maximum (PETM) has been attributed to a rapid rise in greenhouse gas levels. If so, warming should have occurred at all latitudes, although amplified toward the poles. Existing records reveal an increase in high-latitude sea surface temperatures (SSTs) (8° to 10°C) and in bottom water temperatures (4° to 5°C). To date, however, the character of the tropical SST response during this event remains unconstrained. Here we address this deficiency by using paired oxygen isotope and minor element (magnesium/calcium) ratios of planktonic foraminifera from a tropical Pacific core to estimate changes in SST. Using mixed-layer foraminifera, we found that the combined proxies imply a 4° to 5°C rise in Pacific SST during the PETM. These results would necessitate a rise in atmospheric pCO2 to levels three to four times as high as those estimated for the late Paleocene.

title: δ11B of well-preserved brachiopod fossils coupled with geochemical modeling

description: We present the δ11B of well-preserved brachiopod fossils coupled with geochemical modeling to examine how seawater boron responded to abrupt and dynamic climate changes in the Late Paleozoic. The Late Carboniferous, a time of major coal formation and glacio-eustatic sea level changes, is characterized by relatively stable brachiopod δ11B of 15-17‰, similar to values seen in modern brachiopods. Brachiopod δ11B dropped by ~5‰ in the early Permian and then re-stabilized at a new value of 10‰ within a few million years. Mass balance models of seawater δ11B reproduced the overall trends in our brachiopod data but failed to capture the large drop in δ11B in the early Permian. Published seawater 87Sr/86Sr and δ44/40Ca data based on brachiopod shells also shift to lower values in the early Permian, suggesting a common control on all three seawater isotope systems. The Permian terrestrial record of evaporites and eolian deposits suggests a prolonged reduced delivery of dissolved weathering products to the ocean, accounting for the change in seawater 87Sr/86Sr. This reduced weathering, in turn, led to increased atmospheric CO2 and lowered seawater pH, which may have significantly decreased major removal mechanisms for seawater calcium and boron leading to declines in both isotope systems. We propose that boron removal via coprecipitation in carbonates and adsorption onto clay minerals was significantly diminished due to a reduction in the availability of the borate aqueous species caused by lowered seawater pH.
