50 year means of oxygen isotope data from ice core NGRIP, supplement to: North Greenland Ice Core Project Members (2004): High-resolution record of Northern Hemisphere climate extending into the last interglacial period. Nature, 431, 147-151

Two deep ice cores from central Greenland, drilled in the 1990s, have played a key role in climate reconstructions of the Northern Hemisphere, but the oldest sections of the cores were disturbed in chronology owing to ice folding near the bedrock. Here we present an undisturbed climate record from a North Greenland ice core, which extends back to 123,000 years before the present, within the last interglacial period. The oxygen isotopes in the ice imply...

Dust concentration in the NGRIP ice core, supplement to: Ruth, Urs; Bigler, Matthias; Röthlisberger, Regine; Siggaard-Andersen, Marie-Louise; Kipfstuhl, Sepp; Goto-Azuma, Kumiko; Hansson, Margareta E; Johnsen, Sigfus J; Lu, Huayu; Steffensen, Jørgen Peder (2007): Ice core evidence for a very tight link between North Atlantic and east Asian glacial climate. Geophysical Research Letters, 34, L03706

Urs Ruth
Corresponding millennial-scale climate changes have been reported from the North Atlantic region and from east Asia for the last glacial period on independent timescales only. To assess their degree of synchrony we suggest interpreting Greenland ice core dust parameters as proxies for the east Asian monsoon systems. This allows comparing North Atlantic and east Asian climate on the same timescale in high resolution ice core data without relative dating uncertainties. We find that during Dansgaard-Oeschger...

Gravity mapping in the southern Weddell Sea region, Antarctica (Scale 1:2 000 000), supplement to: Aleshkova, Nadezhda D; Golynsky, Alexander V; Kurinin, Rem G; Mandrikov, V S (2000): Gravity mapping in the southern Weddell Sea region. (Explanatory note for free-air and Bounger anomalie maps). Polarforschung, 67(3), 163-177

Nadezhda D Aleshkova, Alexander V Golynsky, Rem G Kurinin & V S Mandrikov
New maps of free-air and the Bouguer gravity anomalies on the Weddell Sea sector (70-81° S, 6-75° W) of Antarctica are presented. These maps are based on the first computer compilation of available gravity data collected by ''Sevmorgeologia'' in 1976-89 in the southern Weddell Sea and adjacent coasts of western Dronning Maud Land (WDML) and Coats Land. The accomplished gravity studies comprise airborne observations with a line spacing of about 20 km and conventional measurements...

Distribution of halacarid species in sediment surface samples of Josephine Bank and Great Meteor Bank, Northeast Atlantic (Table 4), supplement to: Bartsch, Ilse (1973): Halacaridae (Acari) von der Josephinebank und der Großen Meteorbank aus dem östlichen Nordatlantik. II. Die Halacaridae aus den Bodengreiferproben. Meteor Forschungsergebnisse, Deutsche Forschungsgemeinschaft, Reihe D Biologie, Gebrüder Bornträger, Berlin, Stuttgart, D15, 51-78

Ilse Bartsch
In 22 samples, 6 from Josephine Bank and 16 from the Great Meteor Bank, 14 halacarid species were found and described. Halacarus spiniger n. sp., Copidognathus magniporus n. sp., Arhodeoporus lineatus n. sp., A. brevocularis n. sp., Coloboceras karamani n. sp., Scaptognathus minutus n. sp., and Atelopsalis newelli were hithero unknown. Acaromantis squilla Trouessart & Neumann and Atelopsalis tricuspis Trouessart were redescribed. Four larvae, probably belonging to Copidognathus longips Bartsch, C. tricorneata (Lohmann), Lohmannella falcata...

Distribution of the sand-ascidian Seriocarpa rhizoides in surface sediments of Josephine-Bank, North Atlantic (Table 4), supplement to: Diehl, Manfred (1970): Die neue, ökologisch extreme Sand-Ascidie von der Josephine-Bank: Seriocarpa rhizoides Diehl 1969 (Ascidiacea, Styelidae). Meteor Forschungsergebnisse, Deutsche Forschungsgemeinschaft, Reihe D Biologie, Gebrüder Bornträger, Berlin, Stuttgart, D7, 43-58

Manfred Diehl
Seriocarpa rhizoides Diehl 1969 was collected in abundance from the calcareous sand of the Josephine Bank (between Portugal and Madeira) during the „Meteor“ seamount cruises in 1967. Attachment in this loose soft substratum is effected by fine anchoring strands of the tests. Two irregular series of small polycarp-like hermaphrodite bodies which are embedded in a connective tissue lie directly below the endostyle, forming a tubular compound gonad, but without common ducts. The intermediate nature of...

The near-bottom plankton and benthic invertebrate fauna of Josephine and Great Meteor Seamounts (Table 2), supplement to: Hesthagen, Ivar H (1970): On the near-bottom plankton and benthic invertebrate fauna of the Josephine Seamount and the Great Meteor Seamount. Meteor Forschungsergebnisse, Deutsche Forschungsgemeinschaft, Reihe D Biologie, Gebrüder Bornträger, Berlin, Stuttgart, D8, 61-70

Ivar H Hesthagen
15 samples obtained with Beyer's epibenthic closing net were studied quantitatively. The numbers of epi- and endobenthic animals were found to be correlated with the volume of sediment in the samples. Among the planktonic components, calanoid copepodes were strongly predominant. In the samples obtained on the Great Meteor Seamount, very much larger numbers of these animals were caught in the daytime than at night. Possible explanations for this difference are suggested.

Distribution of benthic abyssal gastropods in the Iberian Deep-Sea Basin (Table 2), supplement to: Fechter, Rosina (1979): Gastropoden aus der Iberischen Tiefsee. Meteor Forschungsergebnisse, Deutsche Forschungsgemeinschaft, Reihe D Biologie, Gebrüder Bornträger, Berlin, Stuttgart, D30, 23-40

Rosina Fechter
During the cruises 3 and 15 of R.V. "Meteor", representatives of 7 families of benthic abyssal gastropods were collected. The prevalent group was the Turridae; the Naticidae are represented by 2 species, the remaining families by a single species each. A survey of the frequency and distribution of the species within the study area is given. A systematic part deals with the individual species in detail, including notes on taxonomy, material and distribution. Concerning the...

Carbonate saturation in the water column of station M8_056 off Cap Sao Vincente, Portugal (Table 1), supplement to: Gieskes, Joris M (1970): Einige Beobachtungen über Lösungsvorgänge am Boden des Ozeans. Meteor Forschungsergebnisse, Deutsche Forschungsgemeinschaft, Reihe A Allgemeines, Physik und Chemie des Meeres, Gebrüder Bornträger, Berlin, Stuttgart, A8, 12-17

Joris M Gieskes
Changes in the dissolved oxygen content, the alkalinity, and the pH in sea water near the ocean floor are interpreted in terms of chemical and biochemical processes at the sediment water interface. A simple model provides a plausible explanation of the observed phenomena. Special emphasis is given to the importance of borate corrections in the calculation of the solution effects of calcium carbonate.

Benthic organic carbon flux and oxygen penetration depth in the Southern Ocean, supplement to: Sachs, Oliver; Sauter, Eberhard-Jürgen; Schlüter, Michael; Rutgers van der Loeff, Michiel M; Jerosch, Kerstin; Holby, Ola (2009): Benthic organic carbon flux and oxygen penetration reflect different plankton provinces in the Southern Ocean. Deep Sea Research Part I: Oceanographic Research Papers, 56(8), 1319-1335

Oliver Sachs, Eberhard-Jürgen Sauter, Michael Schlüter, Michiel M Rutgers van der Loeff, Kerstin Jerosch & Ola Holby
For the investigation of organic carbon fluxes reaching the seafloor, oxygen microprofiles were measured at 145 sites in different sub-regions of the Southern Ocean. At eleven sites, an in situ oxygen microprofiler was deployed for the measurement of oxygen profiles and the calculation of organic carbon fluxes. At four sites, both in situ and ex situ data were determined for high latitudes. Based on this dataset as well as on previous published data, a relationship...

Sedimentological, organic petrographic and organic chemical characteristics of Albian and Cenomanian/Turonian black shales from the North Altlantic (Tab. 3, 4), supplement to: Stein, Ruediger; Rullkötter, Jürgen; Welte, Dietrich Hugo (1989): Changes in paleoenvironments in the Atlantic Ocean during Cretaceous times: results from black shales studies. Geologische Rundschau, 78(3), 883-901

Ruediger Stein, Jürgen Rullkötter & Dietrich Hugo Welte
Large parts of the Cretaceous Atlantic Ocean are characterized by the wide-spread deposition of organic-carbon-rich sediments ("black shales“), with a maximum occurrence during Aptian/Albian and Cenomanian/Turonian times. In order to explain the origin of these black shales, changes in the amount and type of organic matter in relation to changes in paleogeography, paleoceanic circulation, and paleoclimate have been investigated in detail. The study is mainly based on calculation of accumulation rates of marine and terrigenous...

Chemical composition of clinoptilolite crystals from ODP Hole 108-661A (Table 2), supplement to: Bohrmann, Gerhard; Stein, Ruediger; Faugeres, Jean-Claude (1989): Authigenic zeolites and their relation to silica diagenesis in ODP Site 661sediments (Leg 108, Eastern Equatorial Atlantic). Geologische Rundschau, 78(3), 779-792

Gerhard Bohrmann, Ruediger Stein & Jean-Claude Faugeres
At ODP Site 661 from the continental margin of Northwest Africa, authigenic clinoptilolites were investigated in detail. Based on chemical data, crystal size and shape and their intergrowth with associated mineral phases, two types of clinoptilolite (type A and B) occur representing different diagenetic conditions under which the formation of zeolites took place. Clinoptilolite type A was found in a sediment section comprises numerous hiatuses and stratigraphically condensed sediments and could have been formed during...

Occurence of monothalamous foraminifera in Admiralty Bay, King George Island, West Antarctica (Table 1, 2), supplement to: Majewski, Wojciech; Lecroq, Beatrice; Sinniger, Frederic; Pawlowski, Jan (2007): Monothalamous foraminifera from Admiralty Bay, King George Island, West Antarctica. Polish Polar Research, 28(3), 187-210

Wojciech Majewski, Beatrice Lecroq, Frederic Sinniger & Jan Pawlowski
During the late 2007 austral summer, 20 sediment samples were collected in Admiralty Bay (King George Island, South Shetlands, West Antarctica) from 8 down to 254 m water-depth (mwd). The samples yielded abundant assemblage of monothalamous benthic foraminifera, belonging to at least 40 morphospecies. They constituted the first such collection from Antarctic Peninsula fjords and provided a new insight into this group's diversity and distribution. Among organic-walled taxa, Psammophaga sp., Allogromia cf. crystallifera, and three...

Distribution of Upper Cretaceous deep water agglutinated foraminifera in sediments of the North Atlantic and its marginal seas (Tab. 1), supplement to: Kuhnt, Wolfgang; Kaminski, Michael A; Moullade, Michel (1989): Late Cretaceous deep-water agglutinated foraminiferal assemblages from the North Atlantic and its marginal seas. Geologische Rundschau, 78(3), 1121-1140

Wolfgang Kuhnt, Michael A Kaminski & Michel Moullade
The stratigraphic and biogeographic distribution of more than 170 species of deep-water agglutinated benthic foraminifers (DWAF) from the North Atlantic and adjacent marginal seas has been compared with paleoenvironmental data (e.g. paleobathymetry, oxygenation of the bottom waters, amount of terrigenous input and substrate disturbance). Six general types of assemblages, in which deep water agglutinated taxa occur, are defined from the Turonian to Maastrichtian times:1. High latitude slope assemblages2. Low to mid latitude slope assemblages3. Flysch-type...

Present day and paleo-geographic coordinates, thicknesses and isopach area of the Early Eocene +19 ash layer (Table 1), supplement to: Egger, Hans; Brückl, Ewald (2006): Gigantic volcanic eruptions and climatic change in the early Eocene. International Journal of Earth Sciences, 95, 1065-1070

Hans Egger & Ewald Brückl
23 layers of altered volcanic ash (bentonites) originating from the North Atlantic Igneous Province have been recorded in early Eocene deposits of the Austrian Alps, about 1,900 km away from the source area. The Austrian bentonites are distal equivalents of the ''main ash-phase'' in Denmark and the North Sea basin. We have calculated the total eruption volume of this series as 21,000 km**3, which occurred in 600,000 years. The most powerful single eruption of this...
