title: (Table 1) Interstitial water δ¹³C, tritation alkalinity, and sulphate concentrations of ODP Site 131-808A

description: The d13C values of total inorganic carbon (Sum CO2 ) were measured for interstitial waters extracted from the turbidite and hemipelagic sediments of the Nankai Trough accretionary prism during ODP Leg 131. At 3.0 mbsf in the bacterial sulfate reduction zone, a significant low d13C of -29.8 per mil (PDB) was found, suggesting oxidation of upward-migrated methane from the zone below. At 6.0 mbsf, below the sulfate reduction zone, the d13C value increases abruptly to a maximum value of +12.0 per mil, reflecting an enrichment of 13C in residual Sum CO2 from the bacterial reduction of some Sum CO2 to 12C-enriched CH4. Below 80 mbsf, the 13C values decrease almost linearly with depth to ~ -20 per mil at 1000 mbsf, indicating that the fraction of Sum CO2 derived from thermal degradation of organic material increases gradually with increasing in-situ temperature.

title: Mesozooplankton abundance from net APRIL-2000-K3mockness

description: The samplings of zooplankton were taken with the Mockness net. The type of tows was oblique. The Mockness net is comprised of nine nets that have mesh size 200µm, its mouth area is 1m**2 and the net width is 1m. Both opening and closure of the net are achieved automatically through means of a computer (Wiebe et al. 1985, doi:10.1007/BF00397811). Mockness is manufactured in such a way, so that each tow can be performed at a 45o corner, which is usually achieved when the speed of the vessel equals roughly to 2kn. The filtered water volume was measured by the MOCNESS flow meter.

title: (Supplement) Groundwater quality in Lahore Pakistan: emphasis on Arsenic and Fluoride levels

description: The dataset provides detailed information on the study that was conducted in Lahore's 7 major towns. The sample was taken from 472 tubewells and analyzed for major cations and anions using APHA 2012 techniques as explained herein. Besides, E.coli determination was done to check for microbial contamination. The data includes results from PHREEQC modeling of As(III)/ As(V) species and saturation indices as well as Aquachem's computed hydrochemical water facies. The WHO (2011) and EPA standards included in Aquachem identified the parameters that where in violation. Bicarbonates dominated the groundwater types with 50.21% of the samples exceeding the EPA maximum permissible limit of 250 mg/L in drinking water. Similarly, 30.51% of the samples had TDS values greater than 500 mg/L while 85.38 % of the samples exceed 10 µg/L threshold limit value of arsenic. Also, instances of high magnesium hazard values were observed which requires constant assessment if the groundwater is used for irrigation. Higher than 50% MH values are detrimental to crops which may reduce the expected yields.The membrane filtration technique using m-Endo Agar indicated that 3.59% samples had TNC (too numerous to count) values for E.coli while 5.06% showed values higher than 0 cfu/ 100 ml acceptable value in drinking water. Any traces of E-coli in a groundwater sample indicate recent fecal contamination. Such outcomes signify presence of enteric pathogens. If the groundwater is not properly dosed with disinfectants it may cause harm to human health. It is concluded that more studies are needed and proper groundwater management implement to safeguard the lives of communities that depend solely on groundwater in the city.

title: Stable oxygen and carbon isotope ratios for Early to Middle Cretaceous benthic and planktonic foraminifera of DSDP Hole 62-463 from the Mid Pacific Mountains (Table 1)

description: Stable isotopic measurements have been made on planktonic and benthic foraminifera of Early to mid-Cretaceous (Early Albian-Cenomanian) age from DSDP site 463 located in the Pacific Ocean. The degree of alteration of the foraminifera has been assessed through the application of scanning electron microscopy. The oxygen isotope data support the view that during the Cenomanian 'globigerine' foraminifera, such as the genus Hedbergella, inhabited near-surface waters, whilst the flattened, keeled, morphotypes lived deeper within the water column. The carbon isotope data reveal a more complex pattern as the delta13C values from planktonic species essentially show a large overlap, which is interpreted in terms of a weak delta13C gradient existing in the upper part of the ocean. In contrast, the oxygen isotope data from planktonic foraminifera from the Late Albian display no discernible depth stratification pattern and the delta13C data also show a large overlap of values indicative of a complete disruption of the upper part of the thermocline. A relatively low surface to bottom water temperature gradient within the Early-Middle Albian part of the succession may reflect a well-mixed ocean. Inferred cool ocean temperatures (and/or high salinities) for the Early Albian may reflect increased oceanic poleward heat transport. An increase in temperature (and/or decrease in salinity) in the Cenomanian suggests a reduction of the poleward heat flux, promoting the build-up of limited polar ice during this period of tropical warmth.

title: Stable carbon isotope ratios of the planktonic foraminifera Globigerina bulloides in ODP Hole 117-723A from the Arabian Sea (Table 2)

description: Production of Globigerina bulloides generally increases during upwelling in the tropical ocean and, in particular, during southwest monsoon season in the Arabian Sea. We studied the d13C signatures of G. bulloides from Ocean Drilling Program (ODP) site 723A located in the intense upwelling area along the Oman Margin, Arabian Sea. The delta13C signature of G. bulloides from the Oman Margin during the last 19 ka ranges from -2.65‰ to -1.13‰. Strikingly, the delta13C values of G. bulloides are about 1‰ lower than that of benthic foraminifera Uvigerina excellens at this site. Apparently, the vital effects induced carbon isotopic fractionation in G. bulloides results in abnormal delta13C values. During upwelling seasons, G. bulloides calcifies faster, perhaps because of high-nutrient availability. Faster calcification rates in this species require higher respiration, which involves more respired CO2 enriched with 12C accounting for nearly 10% of shell carbon. Therefore, the combination the foraminifera of faster calcification and involvement of respired CO2 would induce more negative delta13C in G. bulloides compared to other foraminifera. Apart from vital effects, the environmental changes caused by the variations of upwelling intensity during Holocene and last glacial maximum also affected the down-core delta13C record of G. bulloides in the Arabian Sea. Significant ontogenic differences in both delta18O and delta13C occurred between large and small size classes of G. bulloides.

title: (Table T3) Calcium carbonate mineralogy of ODP Leg 182 sites, Great Australian Bight

description: Carbonate mineralogy was determined on a total of 2845 samples from Sites 1126-1132 situated on the southern margin of the Australian continent. Five of these sites represent distal to proximal transects (Sites 1127-1131-1129 and 1132-1130), which penetrate principally Pleistocene-aged sediments. These sediments exhibit high concentrations of aragonite and high-Mg calcite (HMC) in shallow portions of the core, decreasing with depth. Dolomite was ubiquitous throughout these five cores and showed an inverse correlation in some instances with HMC. Sites 1126 and 1128 penetrated older strata and show lower concentrations of aragonite, HMC, and dolomite.

title: Thallium concentrations and isotope composition of MORB glasses and altered oceani crust from DSDP/ODP Hole 504B and DSDP Hole 52-417D

description: Hydrothermal fluids expelled from the seafloor at high and low temperatures play pivotal roles in controlling seawater chemistry. However, the magnitude of the high temperature water flux of mid-ocean ridge axes remains widely disputed and the volume of low temperature vent fluids at ridge flanks is virtually unconstrained. Here, we determine both high and low temperature hydrothermal fluid fluxes using the chemical and isotopic mass balance of the element thallium (Tl) in the ocean crust. Thallium is a unique tracer of ocean floor hydrothermal exchange because of its contrasting behavior during seafloor alteration at low and high temperatures and the distinctive isotopic signatures of fresh and altered MORB and seawater. The calculated high temperature hydrothermal water flux is (0.17-2.93)*10**13 kg/yr with a best estimate of 0.72*10**13 kg/yr. This result suggests that only about 5 to 80% of the heat available at mid-ocean ridge axes from the crystallization and cooling of the freshly formed ocean crust, is released by high temperature black smoker fluids.The residual thermal energy ismost likely lost via conduction and/or through the circulation of intermediate temperature hydrothermal fluids that do not alter the chemical budgets of Tl in the ocean crust. The Tl-based calculations indicate that the low temperature hydrothermal water flux at ridge flanks is (0.2-5.4)*10**17 kg/yr. This implies that the fluids have an average temperature anomaly of only about 0.1 to 3.6 °C relative to ambient seawater. If these low temperatures are correct then both Sr and Mg are expected to be relatively unreactive in ridge-flank hydrothermal systems and this may explain why the extent of basalt alteration that is observed for altered ocean crust appears insufficient to balance the oceanic budgets of 87Sr/86Sr and Mg.
