Hydrocarbon analyses of submarine mud volcanoes (MV) in the Kumano forearc basin, supplement to: Pape, Thomas; Geprägs, Patrizia; Hammerschmidt, Sebastian; Wintersteller, Paul; Wei, Jiangong; Fleischmann, Timo; Bohrmann, Gerhard; Kopf, Achim J (2014): Hydrocarbon seepage and its sources at mud volcanoes of the Kumano forearc basin, Nankai Trough subduction zone. Geochemistry, Geophysics, Geosystems, 15(6), 2180-2194

Thomas Pape, Patrizia Geprägs, Sebastian Hammerschmidt, Paul Wintersteller, Jiangong Wei, Timo Fleischmann, Gerhard Bohrmann & Achim J Kopf
Twelve submarine mud volcanoes (MV) in the Kumano forearc basin within the Nankai Trough subduction zone were investigated for hydrocarbon origins and fluid dynamics. Gas hydrates diagnostic for methane concentrations exceeding solubilities were recovered from MVs 2, 4, 5, and 10. Molecular ratios (C1/C2<250) and stable carbon isotopic compositions (d13C-CH4 >-40 per mil V-PDB) indicate that hydrate-bound hydrocarbons (HCs) at MVs 2, 4, and 10 are derived from thermal cracking of organic matter. Considering thermal...

Dead Sea lake level for the last 260 ka, supplement to: Waldmann, Nicolas; Torfstein, Adi; Stein, Mordechai (2010): Northward intrusions of low- and mid-latitude storms across the Saharo-Arabian belt during past interglacials. Geology, 38(6), 567-570

Nicolas Waldmann, Adi Torfstein & Mordechai Stein
The rain regime of the Levant during the late Quaternary was controlled primarily by Mediterranean cyclonic systems associated with North Atlantic climate shifts. Lake levels in the Dead Sea basin have been robust recorders of the regional hydrology and generally indicate highstand (wet) conditions throughout glacial intervals and lowstands (dry) during interglacials. However, sporadic deposition of travertines and speleothems occurred in the Negev Desert and Arava Valley during past interglacials, suggesting intrusions of humidity from...

Sources and seasonality of polycyclic aromatic hydrocarbons transported to Alert, Canadian Arctic, supplement to: Wang, Rong; Tao, Shu; Wang, Bin; Yang, Yu; Lang, Chang; Zhang, Yanxu; Hu, Jing; Ma, Jianmin; Hung, Hayley (2010): Sources and pathways of polycyclic aromatic hydrocarbons transported to Alert, the Canadian High Arctic. Environmental Science & Technology, 44(3), 1017-1022

Rong Wang, Shu Tao, Bin Wang, Yu Yang, Chang Lang, Yanxu Zhang, Jing Hu, Jianmin Ma & Hayley Hung
A probabilistic function (integrated source contribution function, ISCF) based on backward air mass trajectory calculation was developed to track sources and atmospheric pathways of polycyclic aromatic hydrocarbons (PAHs) to the Canadian High Arctic station of Alert. In addition to the movement of air masses, the emission intensities at the sources and the major processes of partition, indirect photolysis, and deposition occurring on the way to the Arctic were incorporated into the ISCF. The predicted temporal...

Isotope analysis and heat flow measurements of Maria S. Merian cruise MSM21/4 on the western Svalbard margin, supplement to: Berndt, Christian; Feseker, Tomas; Treude, Tina; Krastel, Sebastian; Liebetrau, Volker; Niemann, Helge; Bertics, Victoria J; Dumke, Ines; Dünnbier, Karolin; Ferre, Benedicte; Graves, Carolyn; Gross, Felix; Hissmann, Karen; Hühnerbach, Veit; Krause, Stefan; Lieser, Kathrin; Schauer, Jürgen; Steinle, Lea (2014): Temporal constraints on hydrate-controlled methane seepage off Svalbard.

Methane hydrate is an ice-like substance that is stable at high-pressure and low temperature in continental margin sediments. Since the discovery of a large number of gas flares at the landward termination of the gas hydrate stability zone off Svalbard, there has been concern that warming bottom waters have started to dissociate large amounts of gas hydrate and that the resulting methane release may possibly accelerate global warming. Here, we can corroborate that hydrates play...

Nd-Sr isotopes, diatom and biogenic opal content of Pliocene sediments from IODP Site 318-U1361, supplement to: Cook, Carys P; van de Flierdt, Tina; Williams, Trevor; Hemming, Sidney R; Iwai, Masao; Kobayashi, Munemasa; Jiménez-Espejo, Francisco J; Escutia, Carlota; Gonzàlez, Jhon Jairo; Khim, Boo-Keun; McKay, Robert M; Passchier, Sandra; Bohaty, Steven M; Riesselman, Christina R; Tauxe, Lisa; Sugisaki, Saiko; Lopez Galindo, Alberto; Patterson, Molly O; Sangiorgi, Francesca; Pierce, Elizabeth L; Brinkhuis, Henk; Klaus, Adam; Fehr, Annick; Bendle, James A; Bijl, Peter K; Carr, Stephanie A; Dunbar, Robert B; Flores, José-Abel; Hayden, Travis G; Katsuki, Kota; Kong, Gee Soo; Nakai, Mutsumi; Olney, Matthew P; Pekar, Stephen F; Pross, Jörg; Röhl, Ursula; Sakai, Toyusaburo; Shrivastava, Prakash Kumar; Stickley, Catherine E; Tuo, Shouting; Welsh, Kevin; Yamane, Masako (2013): Dynamic behaviour of the East Antarctic ice sheet during Pliocene warmth. Nature Geoscience, 6(9), 765-769

Carys P Cook, Tina van de Flierdt, Trevor Williams, Sidney R Hemming, Masao Iwai, Munemasa Kobayashi, Francisco J Jiménez-Espejo, Carlota Escutia, Jhon Jairo Gonzàlez, Boo-Keun Khim, Robert M McKay, Sandra Passchier, Steven M Bohaty, Christina R Riesselman, Lisa Tauxe, Saiko Sugisaki, Alberto Lopez Galindo, Molly O Patterson, Francesca Sangiorgi, Elizabeth L Pierce, Henk Brinkhuis, Adam Klaus, Annick Fehr, James A Bendle, Peter K Bijl … & Masako Yamane
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...

Benthic foraminiferal Mg/Ca ratios, supplement to: Lear, Caroline H; Rosenthal, Yair; Slowey, Niall C (2002): Benthic foraminiferal Mg/Ca-paleothermometry: a revised core-top calibration. Geochimica et Cosmochimica Acta, 66(19), 3375-3387

Caroline H Lear, Yair Rosenthal & Niall C Slowey
Core-top samples from different ocean basins have been analyzed to refine our current understanding of the sensitivity of benthic foraminiferal calcite magnesium/calcium (Mg/Ca) to bottom water temperatures (BWT). Benthic foraminifera collected from Hawaii, Little Bahama Bank, Sea of Okhotsk, Gulf of California, NE Atlantic, Ceara Rise, Sierra Leone Rise, the Ontong Java Plateau, and the Southern Ocean covering a temperature range of 0.8 to 18°C were used to revise the Cibicidoides Mg/Ca-temperature calibration. The Mg/Ca-BWT...

Halogen deposition in polar snow and ice, supplement to: Spolaor, Andrea; Vallelonga, Paul T; Gabrieli, Jacopo; Martma, Tõnu; Björkman, M P; Isaksson, Elisabeth; Cozzi, Giulio; Turetta, C; Kjær, Helle Astrid; Curran, Mark A J; Moy, Andrew D; Schönhardt, Anja; Blechschmidt, Anne-Marlene; Burrows, John Philip; Plane, J M C; Barbante, Carlo (2014): Seasonality of halogen deposition in polar snow and ice. Atmospheric Chemistry and Physics, 14(6), 9613-9622

The atmospheric chemistry of iodine and bromine in polar regions is of interest due to the key role of halogens in many atmospheric processes, particularly tropospheric ozone destruction. Bromine is emitted from the open ocean but is enriched above first-year sea ice during springtime bromine explosion events, whereas iodine is emitted from biological communities hosted by sea ice. It has been previously demonstrated that bromine and iodine are present in Antarctic ice over glacial-interglacial cycles....

Radiocarbon age, Mg/Ca and δ¹⁸O measurements on planktonic foraminifera of sediment core GeoB12605-3, supplement to: Kuhnert, Henning; Kuhlmann, Holger; Mohtadi, Mahyar; Meggers, Helge; Baumann, Karl-Heinz; Pätzold, Jürgen (2014): Holocene tropical western Indian Ocean sea surface temperatures in covariation with climatic changes in the Indonesian region. Paleoceanography

Henning Kuhnert, Holger Kuhlmann, Mahyar Mohtadi, Helge Meggers, Karl-Heinz Baumann & Jürgen Pätzold
The sea surface temperature (SST) of the tropical Indian Ocean is a major component of global climate teleconnections. While the Holocene SST history is documented for regions affected by the Indian and Arabian monsoons, data from the near-equatorial western Indian Ocean are sparse. Reconstructing past zonal and meridional SST gradients requires additional information on past temperatures from the western boundary current region. We present a unique record of Holocene SST and thermocline depth variations in...

Comparison of Ba/Ca and δ¹⁸OWATER as freshwater proxies: a multi-species core-top study on planktonic foraminifera from the vicinity of the Orinoco River mouth, supplement to: Bahr, André; Schönfeld, Joachim; Hoffmann, Julia; Voigt, Silke; Aurahs, Ralf; Kucera, Michal; Flögel, Sascha; Jentzen, Anna; Gerdes, Axel (2013): Comparison of Ba/Ca and d18Owater as freshwater proxies: A multi-species core-top study on planktonic foraminifera from the vicinity of the Orinoco River mouth. Earth and Planetary Science Letters, 383, 45-57

Past river run-off is an important measure for the continental hydrological cycle and the as-sessment of freshwater input into the ocean. However, paleosalinity reconstructions applying different proxies in parallel often show offsets between the respective methods. Here, we compare the established foraminiferal Ba/Ca and d18OWATER salinity proxies for their capability to record the highly seasonal Orinoco freshwater plume in the eastern Caribbean. For this purpose we obtained a data set comprising Ba/Ca and d18OWATER determined...

Isotopic composition of terrestrial plant waxes (dD and δ¹³C of n-alkanes) of sediment core SO188_342 from the Northern Bay of Bengal for the last 18 ka, supplement to: Contreras-Rosales, Lorena Astrid; Jennerjahn, Tim C; Tharammal, Thejna; Meyer, Vera D; Lückge, Andreas; Paul, André; Schefuß, Enno (2014): Evolution of the Indian Summer Monsoon and terrestrial vegetation in the Bengal region during the past 18 ka. Quaternary Science Reviews, 102, 133-148

Lorena Astrid Contreras-Rosales, Tim C Jennerjahn, Thejna Tharammal, Vera D Meyer, Andreas Lückge, André Paul & Enno Schefuß
The Indian Summer Monsoon (ISM) is a major global climatic phenomenon. Long-term precipitation proxy records of the ISM, however, are often fragmented and discontinuous, impeding an estimation of the magnitude of precipitation variability from the Last Glacial to the present. To improve our understanding of past ISM variability, we provide a continuous reconstructed record of precipitation and continental vegetation changes from the lower Ganges-Brahmaputra-Meghna catchment and the Indo-Burman ranges over the last 18,000 years (18...

Authigenic uranium, mass accumulation rates, benthic δ¹³C and SST during the last interglacial period of ODP Site 177-1094, supplement to: Hayes, Christoper T; Martínez‐García, Alfredo; Hasenfratz, Albin; Jaccard, Samuel L; Hodell, David A; Sigman, Daniel M; Haug, Gerald H; Anderson, Robert F (2014): A stagnation event in the deep South Atlantic during the last interglacial period. Science, 346(6216), 1514-1517

Christoper T Hayes, Alfredo Martínez‐García, Albin Hasenfratz, Samuel L Jaccard, David A Hodell, Daniel M Sigman, Gerald H Haug & Robert F Anderson
Southern Ocean sediments reveal a spike in authigenic uranium 127,000 years ago, within the last interglacial, reflecting decreased oxygenation of deep water by Antarctic Bottom Water (AABW). Unlike ice age reductions in AABW, the interglacial stagnation event appears decoupled from open ocean conditions and may have resulted from coastal freshening due to mass loss from the Antarctic ice sheet. AABW reduction coincided with increased North Atlantic Deep Water (NADW) formation, and the subsequent reinvigoration in...

Cd and δ¹³C reconstruction for the LGM and Holocene in Brazil Margin sediment cores, supplement to: Makou, Mathhew C; Oppo, Delia W; Curry, William B (2010): South Atlantic intermediate water mass geometry for the last glacial maximum from foraminiferal Cd/Ca. Paleoceanography, 25(4), PA4101

Mathhew C Makou, Delia W Oppo & William B Curry
Paleoceanographic studies using benthic foraminiferal Cd as a nutrient tracer have provided a robust means of reconstructing glacial Atlantic Ocean water mass geometry, but a paucity of data from the South Atlantic above 1200 m has limited investigation of Antarctic Intermediate Water (AAIW) configuration and formation. A new Cd depth profile from Brazil margin sediments suggests that AAIW penetrated northward at 1100 m to at least 27°S in the glacial Atlantic. It exhibited substantially reduced...

A global historical radiosondes and tracked balloons archive on standard pressure levels back to the 1920s, supplement to: Ramella Pralungo, Lorenzo; Haimberger, Leopold; Stickler, Alexander (2014): A global radiosonde and tracked balloon archive on 16 pressure levels (GRASP) back to 1905 - Part 1: Merging and interpolation to 00:00 and 12:00 GMT. Earth System Science Data, 6(1), 185-200

Lorenzo Ramella Pralungo, Leopold Haimberger, Alexander Stickler & Stefan Brönnimann
The Comprehensive Historical Upper-Air Network (CHUAN version 1.7), which was substantially extended in 2013, and the Integrated Global Radiosonde Archive (IGRA) are the most important collections of upper-air measurements taken before 1958. CHUAN (tracked) balloon data start in 1900, with higher numbers from the late 1920s onward, whereas IGRA data start in 1937. However, a substantial fraction of those measurements have not been taken at synoptic times (preferably 00:00 or 12:00 GMT) and on altitude...

Field data, numerical simulations and probability analyses to assess lava flow hazards at Mount Etna, supplement to: Del Negro, Ciro; Cappello, Annalisa; Neri, Marco; Bilotta, Giuseppe; Hérault, Alexis; Ganci, Gaetana (2013): Lava flow hazards at Mount Etna: constraints imposed by eruptive history and numerical simulations. Scientific Reports, 3, 3493

Ciro Del Negro, Annalisa Cappello, Marco Neri, Giuseppe Bilotta, Alexis Hérault & Gaetana Ganci
Improving lava flow hazard assessment is one of the most important and challenging fields of volcanology, and has an immediate and practical impact on society. Here, we present a methodology for the quantitative assessment of lava flow hazards based on a combination of field data, numerical simulations and probability analyses. With the extensive data available on historic eruptions of Mt. Etna, going back over 2000 years, it has been possible to construct two hazard maps,...

Age models of northern North Atlantic sediment cores, supplement to: Thornalley, David JR; Elderfield, Henry; McCave, I Nick (2010): Intermediate and deep water paleoceanography of the northern North Atlantic over the past 21,000 years. Paleoceanography, 25(1), PA1211

David JR Thornalley, Henry Elderfield & I Nick McCave
Benthic foraminiferal stable isotope records from four high-resolution sediment cores, forming a depth transect between 1237 m and 2303 m on the South Iceland Rise, have been used to reconstruct intermediate and deep water paleoceanographic changes in the northern North Atlantic during the last 21 ka (spanning Termination I and the Holocene). Typically, a sampling resolution of ~100 years is attained. Deglacial core chronologies are accurately tied to North Greenland Ice Core Project (NGRIP) ice...

Age determination and model of sediment core RAPiD-15-4P, supplement to: Thornalley, David JR; McCave, I Nick; Elderfield, Henry (2010): Freshwater input and abrupt deglacial climate change in the North Atlantic. Paleoceanography, 25(1), PA1201

David JR Thornalley, I Nick McCave & Henry Elderfield
Greenland ice core records indicate that the last deglaciation (~7-21 ka) was punctuated by numerous abrupt climate reversals involving temperature changes of up to 5°C-10°C within decades. However, the cause behind many of these events is uncertain. A likely candidate may have been the input of deglacial meltwater, from the Laurentide ice sheet (LIS), to the high-latitude North Atlantic, which disrupted ocean circulation and triggered cooling. Yet the direct evidence of meltwater input for many...

Physico-chemical parameters of sediment core PG1975-1 (09-Tik-05) from a Tundra Lake, Northeastern Siberia, supplement to: Biskaborn, Boris K; Herzschuh, Ulrike; Bolshiyanov, Dimitry Yu; Schwamborn, Georg; Diekmann, Bernhard (2013): Thermokarst processes and depositional events in a Tundra Lake, Northeastern Siberia. Permafrost and Periglacial Processes, 24(3), 160-174

Boris K Biskaborn, Ulrike Herzschuh, Dimitry Yu Bolshiyanov, Georg Schwamborn & Bernhard Diekmann
The relationships between thermokarst activity, limnogeological processes and climate change in the Siberian Arctic are not well understood. The objective of this paper is to identify the factors controlling the patterns of deposition, using grain size distribution, organic content, elemental composition and mineralogical composition of a 137-cm long sediment core with a maximum age of ~10.9 cal. kyr BP from Lake El'gene-Kyuele in the tundra of northeastern Siberia. Eight fine sand layers are attributed to...

Stable isotope record, carbonate and organic carbon content of the Miocene section of IODP Site 321-U1337, supplement to: Holbourn, Ann; Kuhnt, Wolfgang; Kochhann, Karlos Guilherme Diemer; Andersen, Nils; Meier, K J Sebastian (2015): Global perturbation of the carbon cycle at the onset of the Miocene Climatic Optimum. Geology, 43(2), 123-126

Ann Holbourn, Wolfgang Kuhnt, Karlos Guilherme Diemer Kochhann, Nils Andersen & K J Sebastian Meier
The Miocene Climatic Optimum (~17-14.7 Ma) represents one of several major interruptions in the long-term cooling trend of the past 50 million years. To date, the processes driving high-amplitude climate variability and sustaining global warmth during this remarkable interval remain highly enigmatic. We present high-resolution benthic foraminiferal and bulk carbonate stable isotope records in an exceptional, continuous, carbonate-rich sedimentary archive (Integrated Ocean Drilling Program Site U1337, eastern equatorial Pacific Ocean), which offer a new view...

Water temperature and salinity data from southern elephant seals from Marion Island, supplement to: Roquet, Fabien; Wunsch, Carl; Forget, Gael; Heimbach, Patrick; Guinet, Christophe; Reverdin, Gilles; Charrassin, Jean-Benoît; Bailleul, Frederic; Costa, Daniel P; Huckstadt, Luis A; Goetz, Kimberly T; Kovacs, Kit Maureen; Lydersen, Christian; Biuw, Martin; Nøst, Ole Anders; Bornemann, Horst; Plötz, Joachim; Bester, Marthán N; McIntyre, Trevor; Muelbert, Monica C; Hindell, Mark A; McMahon, Clive R; Williams, Guy; Harcourt, Robert; Field, Iain C; Chafik, Leon; Nicholls, Keith W; Boehme, Lars; Fedak, Mike A (2013): Estimates of the Southern Ocean general circulation improved by animal-borne instruments. Geophysical Research Letters, 40(23), 6176-6180

Over the last decade, several hundred seals have been equipped with conductivity-temperature-depth sensors in the Southern Ocean for both biological and physical oceanographic studies. A calibrated collection of seal-derived hydrographic data is now available, consisting of more than 165,000 profiles. The value of these hydrographic data within the existing Southern Ocean observing system is demonstrated herein by conducting two state estimation experiments, differing only in the use or not of seal data to constrain the...

Nd and Sr isotope compositions, REE concentrations and Al/Ca ratios of different phases of surface sediments in the South Pacific, supplement to: Molina-Kescher, Mario; Frank, Martin; Hathorne, Ed C (2014): Nd and Sr isotope compositions of different phases of surface sediments in the South Pacific: Extraction of seawater signatures, boundary exchange, and detrital/dust provenance. Geochemistry, Geophysics, Geosystems

Mario Molina-Kescher, Martin Frank & Ed C Hathorne
The radiogenic isotope composition of neodymium (Nd) and strontium (Sr) are useful tools to investigate present and past oceanic circulation or input of terrigenous material. We present Nd and Sr isotope compositions extracted from different sedimentary phases, including early diagenetic Fe-Mn coatings, "unclean" foraminiferal shells, fossil fish teeth, and detritus of marine surface sediments (core-tops) covering the entire midlatitude South Pacific. Comparison of detrital Nd isotope compositions to deep water values from the same locations...

Seawater Nd and Pb isotopic record in central Pacific and Caribbean sediments, supplement to: Osborne, Anne H; Newkirk, Derrick R; Groeneveld, Jeroen; Martin, Ellen E; Tiedemann, Ralf; Frank, Martin (2014): The seawater neodymium and lead isotope record of the final stages of Central American Seaway closure. Paleoceanography, 29

Anne H Osborne, Derrick R Newkirk, Jeroen Groeneveld, Ellen E Martin, Ralf Tiedemann & Martin Frank
The shoaling and final closure of the Central American Seaway (CAS) resulted in a major change of the global ocean circulation and has been suggested as an essential driver for strengthening of Atlantic Meridional Overturning Circulation (AMOC). The exact timing of CAS closure is key to interpreting its importance. Here we present a reconstruction of deep and intermediate water Nd and Pb isotope compositions obtained from fossil fish teeth and the authigenic coatings of planktonic...

South Pacific dissolved Nd isotope compositions, rare earth element and nutrient concentrations from SONNE cruise SO213, supplement to: Molina-Kescher, Mario; Frank, Martin; Hathorne, Ed C (2013): South Pacific dissolved Nd isotope compositions and rare earth element distributions: Water mass mixing versus biogeochemical cycling. Geochimica et Cosmochimica Acta, 127, 171-189

Mario Molina-Kescher, Martin Frank & Ed C Hathorne
Despite its enormous extent and importance for global climate, the South Pacific has been poorly investigated in comparison to other regions with respect to chemical oceanography. Here we present the first detailed analysis of dissolved radiogenic Nd isotopes (epsilon-Nd) and rare earth elements (REEs) in intermediate and deep waters of the mid-latitude (~40°S) South Pacific along a meridional transect between South America and New Zealand. The goal of our study is to gain better insight...

Fish biometry and concentration of volatile siloxanes in liver of Atlantic cod (Gadus morhua) and shorthorn sculpin (Myxocephalus scorpius) sampled during RV Lance cruise COPOL in 2009, supplement to: Warner, Nicholas A; Evenset, Anita; Christensen, Guttorm; Gabrielsen, Geir W; Borgå, Katrine; Leknes, Henriette (2010): Volatile Siloxanes in the European Arctic: Assessment of Sources and Spatial Distribution. Environmental Science & Technology, 44(19), 7705-7710

Nicholas A Warner, Anita Evenset, Guttorm Christensen, Geir W Gabrielsen, Katrine Borgå & Henriette Leknes
The purpose of this study was to investigate presence and potential accumulation of cyclic volatile methyl siloxanes (cVMS) in the Arctic environment. Octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), and dodecamethylcy-clohexasiloxane (D6) were analyzed in sediment, Zooplankton, Atlantic cod (Gadus morhua), shorthorn sculpin (Myxocephalus scorpius), and bearded seal (Erignathus barbatus) collected from the Svalbard archipelago within the European Arctic in July 2009. Highest levels were found for D5 in fish collected from Adventfjorden, with average concentrations of 176...

Coral communities exposed to differential large amplitude internal waves cooling and a severe heat stress in 2010 in the Andaman Sea, supplement to: Wall, Marlene; Putchim, Lalita; Schmidt, Gertraud; Jantzen, Carin; Khokiattiwong, Somkiat; Richter, Claudio (2015): Large-amplitude internal waves benefit corals during thermal stress. Proceedings of the Royal Society B-Biological Sciences, 282(1799), 20140650

Marlene Wall, Lalita Putchim, Gertraud Schmidt, Carin Jantzen, Somkiat Khokiattiwong & Claudio Richter
Tropical scleractinian corals are particularly vulnerable to global warming as elevated sea surface temperatures (SST) disrupt the delicate balance between the coral host and their algal endosymbionts, leading to symbiont expulsion, mass bleaching and mortality. While satellite sensing of SST has proven a good predictor of coral bleaching at the regional scale, there are large deviations in bleaching severity and mortality on the local scale, which are only poorly understood. Here, we show that internal...

Grain-size distributions and bulk chemistry of sediment core MD00-2361, supplement to: Stuut, Jan-Berend W; Temmesfeld, Felix; De Deckker, Patrick (2014): A 550 ka record of aeolian activity near North West Cape, Australia: inferences from grain-size distributions and bulk chemistry of SE Indian Ocean deep-sea sediments. Quaternary Science Reviews, 83, 83-94

Jan-Berend W Stuut, Felix Temmesfeld & Patrick De Deckker
The terrigenous fraction of sediments from a deep-sea sediment core recovered from the northwestern Western Australian continental slope offshore North West Cape, SE Indian Ocean, reveals a history of Western Australian climate throughout the last 550 ka. End-member modelling of a data set of grain-size distributions (n = 438) of the terrigenous sediment fraction allows to interpret the record in terms of aeolian and fluvial sediment deposition, both related to palaeo-environmental conditions in the North...
