Stable isotope record and aklenonen index of MIS 11 sediments, supplement to: Dickson, Alexander J; Beer, Christopher J; Dempsey, Ciara; Maslin, Mark A; Bendle, James A; McClymont, Erin L; Pancost, Richard D (2009): Oceanic forcing of the Marine Isotope Stage 11 interglacial. Nature Geoscience, 2, 428-433

Alexander J Dickson, Christopher J Beer, Ciara Dempsey, Mark A Maslin, James A Bendle, Erin L McClymont & Richard D Pancost
The interglacial known as Marine Isotope Stage 11 has been proposed to be analogous to the Holocene, owing to similarities in the amplitudes of orbital forcing. It has been difficult to compare the periods, however, because of the long duration of Stage 11 and a lack of detailed knowledge of any extreme climate events that may have occurred. Here we use the distinctive phasing between seasurface temperatures and the oxygen-isotope records of benthic foraminifera in...

Foraminiferal isotope ratios from IODP Site U1313, supplement to: Bolton, Clara T; Wilson, Paul A; Bailey, Ian; Friedrich, Oliver; Beer, Christopher J; Becker, Julia; Baranwal, Soma; Schiebel, Ralf (2010): Millennial-scale climate variability in the subpolar North Atlantic Ocean during the late Pliocene. Paleoceanography, 25, PA4218, 16 pp

Clara T Bolton, Paul A Wilson, Ian Bailey, Oliver Friedrich, Christopher J Beer, Julia Becker, Soma Baranwal & Ralf Schiebel
Large-amplitude millennial-scale climate oscillations have been identified in late Pleistocene climate archives from around the world. These oscillations appear to be of larger amplitude during times of enlarged ice sheets. This observation suggests the existence of a relationship between large-amplitude millennial variations in climate and extreme glacial conditions and therefore that the emergence of millennial-scale climate variability may be linked to the Pliocene intensification of northern hemisphere glaciation (iNHG). Here we test this hypothesis using...

(Table 2) Age interval and accumulation rates of organic and inorganic carbon from ODP Sites 175-1082, 175-1084, 175-1085 and 175-1087

Jaques Giraudeau, Philip A Meyers & Beth A Christensen
The Ocean Drilling Program Leg 175 recovered a unique series of stratigraphically continuous sedimentary sections along the SW African margin, an area which is presently affected by active coastal upwelling. The accumulation rates of organic and inorganic carbon are a major component of this record. Four Leg 175 sites (1082, 1084, 1085, 1087) are chosen as part of a latitudinal transect from the present northern to southern boundaries of the Benguela Current upwelling system, to...

Vitrinite reflectance and carbon chemistry of ODP Leg 122 samples (Table 1), supplement to: Snowdon, Lloyd R; Meyers, Philip A (1992): Source and maturity of organic matter in sediments and rocks from Sites 759, 760, 761, and 764 (Wombat Plateau) and Sites 762 and 763 (Exmouth Plateau). In: von Rad, U; Haq, BU; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 122, 309-315

Lloyd R Snowdon & Philip A Meyers
A summary of shipboard Rock-Eval measurements shows that organic matter in Upper Triassic siltstone from the Wombat Plateau is dominated by Type III kerogen and is thermally immature. Neocomian siltstone from the Exmouth Plateau similarly contain thermally immature Type III organic matter. Overlying Upper Cretaceous to Quaternary carbonates are poor in organic matter at both locations, yet significant amounts of methane-dominated gas are dissolved in the pore waters of the thick carbonate sequence present on...

Extractable hydrocarbon and carbon isotope geochemistry of Lower Cretaceous sediments of the Exmouth Plateau, supplement to: Meyers, Philip A; Snowdon, Lloyd R (1992): Data report: Extractable hydrocarbon and carbon isotope geochemistry of Lower Cretaceous sediments from Sites 762 and 763 on the Exmouth Plateau, Northwest Australian Margin. In: von Rad, U; Haq, BU; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 122, 855-860

Philip A Meyers & Lloyd R Snowdon
The organic geochemical character of rocks selected from Aptian, Valanginian, and Berriasian clay stone and siltstone sequences encountered in Ocean Drilling Program (ODP) Holes 762C and 763C on the Exmouth Plateau was determined by means of a variety of analytical procedures. These sequences represent distal portions of the Mesozoic Barrow delta, in which petroleum source rocks and reservoirs exist on the Australian continent. The organic matter at the ODP sites is thermally immature type III...

Seawater carbonate chemistry and sea urchin Paracentrotus lividus biological processes during experiments, 2011, supplement to: Martin, Sophie; Richier, Sophie; Pedrotti, Maria-Luiza; Dupont, Sam; Castejon, Charlotte; Gerakis, Yannis; Kerros, Marie-Emmanuelle; Oberhänsli, F; Teyssié, Jean-Louis; Jeffree, Ross; Gattuso, Jean-Pierre (2011): Early development and molecular plasticity in the Mediterranean sea urchin Paracentrotus lividus exposed to CO2-driven acidification.

Ocean acidification is predicted to have significant effects on benthic calcifying invertebrates, in particular on their early developmental stages. Echinoderm larvae could be particularly vulnerable to decreased pH, with major consequences for adult populations. The objective of this study was to understand how ocean acidification would affect the initial life stages of the sea urchin Paracentrotus lividus, a common species that is widely distributed in the Mediterranean Sea and the NE Atlantic. The effects of...

Phytoplankton-bacteria coupling under elevated CO2 levels: a stable isotope labelling study, 2010, supplement to: de Kluijver, Anna; Soetaert, Karline; Schulz, Kai Georg; Riebesell, Ulf; Bellerby, Richard G J; Middelburg, Jack J (2010): Phytoplankton-bacteria coupling under elevated CO2 levels: a stable isotope labelling study. Biogeosciences, 7(11), 3783-3797

Anna de Kluijver, Karline Soetaert, Kai Georg Schulz, Ulf Riebesell, Richard G J Bellerby & Jack J Middelburg
The potential impact of rising carbon dioxide (CO2) on carbon transfer from phytoplankton to bacteria was investigated during the 2005 PeECE III mesocosm study in Bergen, Norway. Sets of mesocosms, in which a phytoplankton bloom was induced by nutrient addition, were incubated under 1x (~350 µatm), 2x (~700 µatm), and 3x present day CO2 (~1050 µatm) initial seawater and sustained atmospheric CO2 levels for 3 weeks. 13C labelled bicarbonate was added to all mesocosms to...

Seawater carbonate chemistry and biological processes during experiments with temperate coral Cladocora caespitosa, 2010

Riccardo Rodolfo-Metalpa, Sophie Martin, Christine Ferrier-Pagès & Jean-Pierre Gattuso
Atmospheric CO2 partial pressure (pCO2) is expected to increase to 700 µatm or more by the end of the present century. Anthropogenic CO2 is absorbed by the oceans, leading to decreases in pH and the CaCO3 saturation state of the seawater. Elevated pCO2 was shown to drastically decrease calcification rates in tropical zooxanthellate corals. Here we show, using the Mediterranean zooxanthellate coral Cladocora caespitosa, that an increase in pCO2, in the range predicted for 2100,...

Seawater carbonate chemistry and zooxanthellate coral Cladocora caespitosa boron isotopic and elemental systematics during experiments, 2011, supplement to: Trotter, Julie; Montagna, Paolo; McCulloch, Malcolm T; Silenzi, Sergio; Reynaud, Stéphanie; Mortimer, Graham; Martin, Sophie; Ferrier-Pagès, Christine; Gattuso, Jean-Pierre; Rodolfo-Metalpa, Riccardo (2011): Quantifying the pH 'vital effect' in the temperate zooxanthellate coral Cladocora caespitosa: Validation of the boron seawater pH proxy. Earth and Planetary Science Letters, 303, 163-173

Julie Trotter, Paolo Montagna, Malcolm T McCulloch, Sergio Silenzi, Stéphanie Reynaud, Graham Mortimer, Sophie Martin, Christine Ferrier-Pagès, Jean-Pierre Gattuso & Riccardo Rodolfo-Metalpa
Boron isotopic and elemental systematics are used to define the vital effects for the temperate shallow water Mediterranean coral Cladocora caespitosa. The corals are from a range of seawater pH conditions (pHT ~ 7.6 to ~ 8.1) and environmental settings: (1) naturally living colonies harvested from normal pH waters offshore Levanto, (2) colonies transplanted nearby a subsea volcanic vent system, and (3) corals cultured in aquaria exposed to high (700 µatm) and near present day...

Integrated Data Sets of the EU FP5 Research Project ORFOIS: Origin and fate of biogenic particle fluxes in the ocean and their interactions with atmospheric CO2 concentrations as well as the marine sediment

Nicolas Dittert, Dorothee C E Bakker, Jorgen Bendtsen, Lydie Corrin, Marion Gehlen, Christoph Heinze, Ernst Maier-Reimer, Panagiotis Michalopoulos, Karline Soetaert & Richard S J Tol
For a reliable simulation of the time and space dependent CO2 redistribution between ocean and atmosphere an appropriate time dependent simulation of particle dynamics processes is essential but has not been carried out so far. The major difficulties were the lack of suitable modules for particle dynamics and early diagenesis (in order to close the carbon and nutrient budget) in ocean general circulation models, and the lack of an understanding of biogeochemical processes, such as...

Stable oxygen isotope and Mg/Ca ratios on Globorotalia inflata, supplement to: Groeneveld, Jeroen; Chiessi, Cristiano Mazur (2011): Mg/Ca ratios of Globorotalia inflata as a recorder of permanent thermocline temperatures in the South Atlantic. Paleoceanography, 26, PA2203

Jeroen Groeneveld & Cristiano Mazur Chiessi
We present a species-specific Mg/Ca-calcification temperature calibration for Globorotalia inflata from a suite of 38 core top samples from the South Atlantic (from 8° to 49°S). G. inflata is a deep-dwelling planktonic foraminifer commonly occurring in subtropical to subpolar conditions, which qualifies it for reconstructions of the permanent thermocline. Apparent calcification depths and calcification temperatures were determined by comparing measured d18O with equilibrium d18O of calcite based on water column properties. Based on our core...
