Rio Grande Rise (RGR) is a broad elevation in the South Atlantic Ocean consisting of western and eastern parts, that in total measures about 874 km east-west by about 480 km north-south. There is a scarcity of available information to the scientific community and to address this, the Marine E-tech project has taken a holistic and interdisciplinary scientific approach to understand the oceanographic and geological environment of the rise. Here we present geophysical, geological, biological...

Planktic foraminiferal Mg/Ca ratios of sediment cores in the tropical Atlantic, supplement to: Reissig, Stefan; Nürnberg, Dirk; Bahr, André; Poggemann, David-Willem; Hoffmann, Julia (accepted): Southward displacement of the North Atlantic Subtropical Gyre circulation system during North Atlantic cold spells. Paleoceanography and Paleoclimatology

Stefan Reissig, Dirk Nürnberg, André Bahr, David-Willem Poggemann & Julia Hoffmann
During times of deglacial Atlantic Meridional Overturning Circulation (AMOC) perturbations, the tropical Atlantic experienced considerable warming at subsurface levels. Coupled ocean-atmosphere simulations corroborate the tight teleconnection between the tropical Atlantic and climate change at high northern latitudes, but still underestimate the relevance of the subsurface N Atlantic Subtropical Gyre (STG) for heat and salt storage and its sensitivity to rapid climatic change.Here we reconstruct vertical and lateral temperature and salinity gradients in the tropical W...

Geochemistry of Fe-Mn crusts in sediments of the Central Indian Ridge, supplement to: Kuhn, Thomas; Bau, Michael; Blum, Nevin; Halbach, Peter (1998): Origin of negative Ce anomalies in mixed hydrothermal-hydrogenetic Fe-Me crusts from the Central Indian Ridge. Earth and Planetary Science Letters, 163(1-4), 207-220

Thomas Kuhn, Michael Bau, Nevin Blum & Peter Halbach
Layered Fe-Mn crusts from the off-axis region of the first segment of the Central Indian Ridge north of the Rodrigues Triple Junction were studied geochemically and mineralogically. Vernadite (delta-MnO2) is the main mineral oxide phase. 230Thxs and Co concentrations suggest high growth rates of up to 29 mm/Myr and a maximum age of the basal crust layer of 1 Ma. Whereas most of the major and minor elements show concentrations which are typical of hydrogenetic...

Ages and isotopic signatures of peat cores from a boreal landscape, Interior Alaska, supplement to: Myers-Smith, Isla H; Harden, J W; Wilmking, M; Fuller, C C; McGuire, A David; Chapin, F Stuart (2008): Wetland succession in a permafrost collapse: interactions between fire and thermokarst. Biogeosciences, 5(5), 1273-1286

Isla H Myers-Smith, J W Harden, M Wilmking, C C Fuller, A David McGuire & F Stuart Chapin
To determine the influence of fire and thermokarst in a boreal landscape, we investigated peat cores within and adjacent to a permafrost collapse feature on the Tanana River Floodplain of Interior Alaska. Radioisotope dating, diatom assemblages, plant macrofossils, charcoal fragments, and carbon and nitrogen content of the peat profile indicate ~600 years of vegetation succession with a transition from a terrestrial forest to a sedge-dominated wetland over 100 years ago, and to a Sphagnum-dominated peatland...

Marine and Petroleum Geology

Eric Attias, Kelvin Amalokwu, Mille Watts, Ismael Himar Falcon-Suarez, Hu Gaowei, Angus Best, Karen Weitemeyer & Tim A Minshull
Methane emissions from gas hydrate deposits along continental margins may alter the biogeophysical properties of marine environments, both on local and regional scales. We used a combination of controlled-source electromagnetic (CSEM), seismic and sediment core data obtained in the Nyegga region, offshore Norway, in a joint elastic-electrical ap- proach to quantify marine gas hydrates found within the CNE03 pockmark. Multiscale analysis of two sediment cores reveals significant differences between the CNE03 pock- mark and a...

Metabolic rates and tissue composition of the coral Pocillopora verrucosa over 12 latitudes in the Red Sea characterized by strong temperature and nutrient gradient, supplement to: Sawall, Yvonne; Al-Sofyani, A; Hohn, S; Banguera-Hinestroza, E; Voolstra, Christian R; Wahl, Martin (2015): Extensive phenotypic plasticity of a Red Sea coral over a strong latitudinal temperature gradient suggests limited acclimatization potential to warming. Scientific Reports, 5, 8940

Yvonne Sawall, A Al-Sofyani, S Hohn, E Banguera-Hinestroza, Christian R Voolstra & Martin Wahl
Global warming was reported to cause growth reductions in tropical shallow water corals in both, cooler and warmer, regions of the coral species range. This suggests regional adaptation with less heat-tolerant populations in cooler and more thermo-tolerant populations in warmer regions. Here, we investigated seasonal changes in the in situ metabolic performance of the widely distributed hermatypic coral Pocillopora verrucosa along 12 degrees latitudes featuring a steep temperature gradient between the northern (28.5 degrees N,...

Mineral composition of mid-ocean-ridge basalts from ODP Leg 187 sites, supplement to: Sato, Hiroshi (2004): Mineral compositions of MORB from the Australian Antarctic Discordance (AAD): implications for mantle source characteristics. In: Pedersen, RB; Christie, DM; Miller, DJ (eds.) Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 187, 1-26

Hiroshi Sato
The chemical compositions of olivine, plagioclase, pyroxene, and spinel in lavas collected during Ocean Drilling Program Leg 187 in the Australian Antarctic Discordance, Southeast Indian Ridge (41°-46°S, 126°-135°E) were analyzed, and modeling of the theoretical equilibrium petrogenetic conditions between olivine and melt was conducted. The cores of larger olivine phenocrysts, particularly in the isotopic Indian-type mid-ocean-ridge basalt (MORB), are not equilibrated with melt compositions and are considered to be xenocrystic. Larger plagioclase phenocrysts with compositionally...

Ice and snow characteristics in Prydz Bay in 2006, supplement to: Lei, Ruibo; Li, Zhijun; Cheng, Bin; Zhang, Zhanhai; Heil, Petra (2010): Annual cycle of landfast sea ice in Prydz Bay, east Antarctica. Journal of Geophysical Research, 115(C2)

Ruibo Lei, Zhijun Li, Bin Cheng, Zhanhai Zhang & Petra Heil
Under the Chinese National Antarctic Research Expedition program in 2006, the annual thermal mass balance of landfast ice in the vicinity of Zhongshan Station, Prydz Bay, east Antarctica, was investigated. Sea ice formed from mid-February onward, and maximum ice thickness occurred in late November. Snow cover remained thin, and blowing snow caused frequent redistribution of the snow. The vertical ice salinity showed a 'question-mark-shaped' profile for most of the ice growth season, which only turned...

The warmest global climates of the past 65 million years occurred during the early Eocene epoch (about 55 to 48 million years ago), when the Equator-to-pole temperature gradients were much smaller than today (doi:10.1130/0091-7613(1995)023<1044:ECCALT>2.3.CO;2, doi:10.1038/nature08399) and atmospheric carbon dioxide levels were in excess of one thousand parts per million by volume (doi:10.1016/j.gca.2003.09.002, doi:10.1038/ngeo1186). Recently the early Eocene has received considerable interest because it may provide insight into the response of Earth's climate and biosphere to...

Biogeochemical and physico-chemical characteristics in the gulf of Trieste, Italy, supplement to: Ingrosso, Gianmarco; Giani, Michele; Cibic, Tamara; Karuza, Ana; Kralj, Martina; Del Negro, Paola (2016): Carbonate chemistry dynamics and biological processes along a river-sea gradient (Gulf of Trieste, northern Adriatic Sea). Journal of Marine Systems, 155, 35-49

Michele Giani, Cinzia Comici, Tamara Cibic, Cinzia De Vittor, Ana Karuza, Martina Kralj & Gianmarco Ingrosso
In this paper we investigated, for two years and with a bi-monthly frequency, how physical, chemical, and biological processes affect the marine carbonate system in a coastal area characterized by high alkalinity riverine discharge (Gulf of Trieste, northern Adriatic Sea, Mediterranean Sea).

Carbonate system during the May 2013 MedSeA cruise, supplement to: Hassoun, Abed El Rahman; Guglielmi, Véronique; Gemayel, Elissar; Goyet, Catherine; Abboud-Abi Saab, Marie; Giani, Michele; Ziveri, Patrizia; Ingrosso, Gianmarco; Touratier, Franck (2015): Is the Mediterranean Sea Circulation in a Steady State. Journal of Water Resources and Ocean Science, 4(1), 6

Abed El Rahman Hassoun, Véronique Guglielmi, Elissar Gemayel, Catherine Goyet, Marie Abboud-Abi Saab, Michele Giani, Patrizia Ziveri, Gianmarco Ingrosso & Franck Touratier
Most global ocean models are based on the assumption of a "steady state" ocean. Here, we investigate the validation of this hypothesis for the anthropized Mediterranean Sea. In order to do so, we calculated the mixing coefficients of the water masses detected in this sea via an optimum multiparameter analysis referred to as the MIX approach, using data from the BOUM (2008) and MedSeA (2013) cruises. The comparison of the mixing coefficients of each water...

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...

Eocene cooling linked to early flow across the Tasmanian Gateway, supplement to: Bijl, Peter K; Bendle, James A; Bohaty, Steven M; Pross, Jörg; Schouten, Stefan; Tauxe, Lisa; Stickley, Catherine E; McKay, Robert M; Röhl, Ursula; Olney, M; Sluijs, Appy; Escutia Dotti, Carlota; Brinkhuis, Henk; Expedition 318 Scientists (2013): Eocene cooling linked to early flow across the Tasmanian Gateway. Proceedings of the National Academy of Sciences of the United States of America

Peter K Bijl, James A Bendle, Steven M Bohaty, Jörg Pross, Stefan Schouten, Lisa Tauxe, Catherine E Stickley, Robert M McKay, Ursula Röhl, M Olney, Appy Sluijs, Carlota Escutia Dotti, Henk Brinkhuis & Expedition 318 Scientists
The warmest global temperatures of the past 85 million years occurred during a prolonged greenhouse episode known as the Early Eocene Climatic Optimum (52-50 Ma). The Early Eocene Climatic Optimum terminated with a long-term cooling trend that culminated in continental-scale glaciation of Antarctica from 34 Ma onward. Whereas early studies attributed the Eocene transition from greenhouse to icehouse climates to the tectonic opening of Southern Ocean gateways, more recent investigations invoked a dominant role of...

Warm intervals within the Pliocene epoch (5.33-2.58 million years ago) were characterized by global temperatures comparable to those predicted for the end of this century (Haywood and Valdes, doi:10.1016/S0012-821X(03)00685-X) and atmospheric CO2 concentrations similar to today (Seki et al., 2010, doi:10.1016/j.epsl.2010.01.037; Bartoli et al., 2011, doi:10.1029/2010PA002055; Pagani et al., 2010, doi:10.1038/ngeo724). Estimates for global sea level highstands during these times (Miller et al., 2012, doi:10.1130/G32869.1) imply possible retreat of the East Antarctic ice sheet, but...

Alkenones in surface waters of the Nordic seas, supplement to: Bendle, James A; Rosell-Melé, Antoni; Ziveri, Patrizia (2005): Variability of unusual distributions of alkenones in the surface waters of the Nordic seas. Paleoceanography, 20(2), PA2001

James A Bendle, Antoni Rosell-Melé & Patrizia Ziveri
Samples of filtered particulate organic matter (POM) were obtained during the summers of 1999 and 2000 from the surface waters of the Nordic seas to monitor the spatial distribution of long-chain alkenones. The aim of the study was to appraise existing alkenone-based climatic proxies in northern high latitudes. Unusually high percentages of the tetraunsaturated alkenone were measured in the polar waters of the East Greenland Current, with C37:4 of up to 77% in 80% of...

Paleomagnetic and rock magnetic properties of IODP Expedition 318 cores, supplement to: Tauxe, Lisa; Stickley, Catherine E; Sugisaki, Saiko; Bijl, Peter K; Bohaty, Steven M; Brinkhuis, Henk; Escutia Dotti, Carlota; Flores, José-Abel; Houben, Alexander J P; Iwai, Masao; Jiménez-Espejo, Francisco J; McKay, Robert M; Passchier, Sandra; Pross, Jörg; Riesselman, Christina R; Röhl, Ursula; Sangiorgi, Francesca; Welsh, Kevin; Klaus, Adam; Fehr, Annick; Bendle, James A; Dunbar, Robert G; Gonzales, J; Hayden, Travis; Katsuki, Kota; Olney, Matthew P; Pekar, Stephen F; Shrivastva, P K; van de Flierdt, Tina; Williams, T; Yamane, Masako (2012): Chronostratigraphic framework for the IODP Expedition 318 cores from the Wilkes Land Margin: Constraints for paleoceanographic reconstruction.

The Integrated Ocean Drilling Program Expedition 318 to the Wilkes Land margin of Antarctica recovered a sedimentary succession ranging in age from lower Eocene to the Holocene. Excellent stratigraphic control is key to understanding the timing of paleoceanographic events through critical climate intervals. Drill sites recovered the lower and middle Eocene, nearly the entire Oligocene, the Miocene from about 17 Ma, the entire Pliocene and much of the Pleistocene. The paleomagnetic properties are generally suitable...

Age determinations from northwest Russia, supplement to: Larsen, Eiliv; Lyså, Astrid; Demidov, Igor; Funder, Svend; Houmark-Nielsen, Michael; Kjær, Kurt Henrik; Murray, Andrew Sean (1999): Age and extent of the Scandinavian ice sheet in northwest Russia. Boreas, 28(1), 115-132

Eiliv Larsen, Astrid Lyså, Igor Demidov, Svend Funder, Michael Houmark-Nielsen, Kurt Henrik Kjær & Andrew Sean Murray
The last glacial maximum (LGM) of the Scandinavian ice sheet in the Arkhangelsk region has been identified morphologically as ridges and hummocks in an otherwise flat topography. Stratigraphically the limit is marked by the presence of till above Mikhulinian (last interglacial) sediments inside the ridges and by the absence of till outside the ridges. During the LGM, ice flowed into the region from the north and northwest forming a lobe in the Dvina--Vaga depression. The...
