Holes drilled into the volcanic and ultrabasic basement of the Izu-Ogasawara and Mariana forearc terranes during Leg 125 provide data on some of the earliest lithosphere created after the start of Eocene subduction in the Western Pacific. The volcanic basement contains three boninite series and one tholeiite series. (1) Eocene low-Ca boninite and low-Ca bronzite andesite pillow lavas and dikes dominate the lowermost part of the deep crustal section through the outer-arc high at Site...

Distribution of radiolaria in Oligocene to Pleistocene sediments of the North-West Pacific, supplement to: Levykina, L E (1986): Stratigraphy of Neogene deposits in North-West Pacific according to radiolarians. Transactions of the Geological Institute, USSR Academy of Sciences, 413, 116 pp

L E Levykina
Neogene stratigraphy of the tropical and subtropical Pacific on radiolaria is studied in the book. A detailed comparison of coeval systems from tropics and subtropics is given. A possibility of use of a uniform zonal scale in these areas is proved. Magnitude of changes of complexes on borders of Neogene zones is studied in detail. Six stages in development of radiolarians are identified in the tropics in Neogene. Stratigraphic levels, where the greatest changes of...

Investigation of the sedimentary record of pre-Alpine Lake Mondsee (Upper Austria) focused on the environmental reaction to rapid Lateglacial climatic changes. Results of this study reveal complex proxy responses that are variable in time and influenced by the long-term evolution of the lake and its catchment. A new field sampling approach facilitated continuous and precisely controlled parallel sampling at decadal to sub-annual resolution for µ-XRF element scanning, carbon geochemistry, stable isotope measurements on ostracods, pollen...

Mineralogy of southern Kerguelen Plateau sediments, supplement to: Holmes, Mary Anne (1992): Cretaceous subtropical weathering followed by cooling at 60°S latitude: the mineral composition of southern Kerguelen Plateau sediment, Leg 120. In: Wise, SW; Schlich, R; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 120, 99-111

Mary Anne Holmes
Kaolinite, goethite, minor hematite, and gibbsite were found in fluvial upper Lower Cretaceous basal sediment from the Southern Kerguelen Plateau, Sites 748 and 750, 55°S latitude. This mineral assemblage, derived from the weathering of basalt, indicates near-tropical weathering conditions with high orographic rainfall, at least 100 cm per year. The climate deteriorated by the Turonian or Coniacian, as indicated by the decline in kaolinite content of this sediment.The Upper Cretaceous sediment at Site 748 consists...

Geochemistry of Kerguelen-Heard Plateau basalts, supplement to: Salters, Vincent J M; Storey, Michael; Sevigny, James H; Whitechurch, Hubert (1992): Trace element and isotopic characteristics of Kerguelen-Heard Plateau basalts. In: Wise, SW; Schlich, R; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 120, 55-62

Vincent J M Salters, Michael Storey, James H Sevigny & Hubert Whitechurch
During Leg 120 basalts were recovered at four drill holes on the Kerguelen-Heard Plateau. This paper reports the trace element and Sr, Nd, Hf, and Pb isotopic characteristics of these basalts and compares these basalts with Indian Ocean basalts and Kerguelen and Heard island volcanics. Kerguelen-Heard Plateau basalts are extremely heterogeneous in character. Intersite variations are larger than intrasite variations. Part of the chemical variations of the plateau volcanics overlap with those characteristics of Kerguelen...

Chemistry of bulk-rocks and minerals of ODP Hole 120-748C, supplement to: Bitschene, Peter Rene; Holmes, Mary Anne; Breza, James R (1992): Composition and origin of Cr-rich glauconitic sediments from the southern Kerguelen Plateau (Site 748). In: Wise, SW; Schlich, R; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 120, 113-134

Peter Rene Bitschene, Mary Anne Holmes & James R Breza
Five hundred meters of a unique Upper Cretaceous Cr-rich glauconitic sequence (Unit III) that overlies a 3-m-thick alkali-basalt flow with underlying epiclastic volcanogenic sediments was drilled at ODP Leg 120 Site 748. The Cr-rich glauconitic sequence is lithostratigraphically and biostratigraphically divided into three subunits (IIIA, IIIB, IIIC) that can also be recognized by the Cr concentration of the bulk sediment, which is low (<200 ppm) in Subunits IIIC and IIIA and high (400-800 ppm) in...

Grain size investigations of sediments off the coast of Istria, supplement to: Fütterer, Dieter K (1969): Die Sedimente der nördlichen Adria vor der Küste Istriens. Göttinger Arbeiten zur Geologie und Paläontologie, 3, 57 pp

Dieter K Fütterer
Composition, grain-size distribution, and areal extent of Recent sediments from the Northern Adriatic Sea along the Istrian coast have been studied. Thirty one stations in four sections vertical to the coast were investigated; for comparison 58 samples from five small bays were also analyzed. Biogenic carbonate sediments are deposited on the shallow North Adriatic shelf off the Istrian coast. Only at a greater distance from the coast are these carbonate sediments being mixed with siliceous...

Late Pliocene and Early Pleistocene dinoflagellate cysts and sea surface temperture reconstruction for several IODP and DSDP sites in the North Atlantic, supplement to: De Schepper, Stijn; Fischer, Eva I; Groeneveld, Jeroen; Head, Martin J; Matthiessen, Jens (2011): Deciphering the palaeoecology of Late Pliocene and Early Pleistocene dinoflagellate cysts. Palaeogeography, Palaeoclimatology, Palaeoecology, 309(1-2), 17-32

Stijn De Schepper, Eva I Fischer, Jeroen Groeneveld, Martin J Head & Jens Matthiessen
In an attempt to document the palaeoecological affinities of individual extant and extinct dinoflagellate cysts, Late Pliocene and Early Pleistocene dinoflagellate cyst assemblages have been compared with geochemical data from the same samples. Mg/Ca ratios of Globigerina bulloides were measured to estimate the spring-summer sea-surface temperatures from four North Atlantic IODP/DSDP sites. Currently, our Pliocene-Pleistocene database contains 204 dinoflagellate cyst samples calibrated to geochemical data. This palaeo-database is compared with modern North Atlantic and global...

Modes of sapropel formation in the eastern Mediterranean: some constraints based on pyrite properties, supplement to: Passier, Hilde F; Middelburg, Jack J; de Lange, Gert Jan; Böttcher, Michael E (1999): Modes of sapropel formation in the eastern Mediterranean: some constraints based on pyrite properties. Marine Geology, 153(1-4), 199-219

Hilde F Passier, Jack J Middelburg, Gert Jan de Lange & Michael E Böttcher
Pyrite formation within and directly below sapropels in the eastern Mediterranean was governed by the relative rates of sulphide production and Fe liberation and supply to the organic-rich layers. At times of relatively high [SO4]2- reduction, sulphide could diffuse downward from the sapropel and formed pyrite in underlying sediments. The sources of Fe for pyrite formation comprised detrital Fe and diagenetically liberated Fe(II) from sapropel-underlying sediments. In organic-rich sapropels, input of Fe from the water...

Ages and sedimentation rates of bottom sediments from the south arid zone of the Pacific Ocean, supplement to: Dekov, Vesselin M; Kuptsov, Vladimir M (1990): Rates of accumulation of metal-bearing sediments on the East Pacific Rise (20°S). Oceanology, 30(3), 321-324

Vesselin M Dekov & Vladimir M Kuptsov
Radiocarbon datings are used to calculate mean sedimentation rates of metalliferous sediments in the southern arid zone of the Pacific Ocean adjoining the axis of the East Pacific rise (20°S). Owing to low sedimentation rates and intense mixing, only averaged figures could be obtained for ages less than 16 ky. Sedimentation rate varies from 0.3 to about 1 cm/1000 years in the surface layer and is several times higher in the time interval from 20...

Composition of standard reference samples of Fe-Mn nodules and bottom sediments, supplement to: Berkovits, Leonid A; Obol'yaninova, V G; Baturin, Gleb N (1990): Standard specimens of iron-manganese nodules and surrounding sediments. Oceanology, 30(3), 329-335

Leonid A Berkovits, V G Obol'yaninova & Gleb N Baturin
The first series of Soviet standard reference samples of composition of ore materials and ocean pelagic sediments has been created. It includes iron-manganese nodules (SDO-4, SDO-5 and SDO-6), ore crusts (SDO-7) diatomaceous ooze (SDO-8), and deep-sea red clays (SDO-9). The standards are intended to serve as a metrologic basis for physical, physicochemical and chemical analyses of iron-manganese minerals and ocean sediments. The standards are provided with certified analyses of rock-forming components and certain trace elements....

Oxygen and carbon isotopic records have been developed for the Cenozoic carbonate oozes of Sites 752, 754, 756, and 757 based on the analysis of monospecific benthic foraminifers. The intent of this report is to provide a basic isotopic stratigraphy for use in other paleoceanographic studies. The oxygen isotope record displays the enrichments associated with cooling or ice volume buildup at the Eocene/Oligocene boundary, in the middle Miocene, and in the upper Pliocene. The carbon...

Age determination of Paleogene sediments from the Prysz Bay, supplement to: Thierstein, Hans R; MacDougall, J Douglas; Martin, Ellen E; Larsen, Birger; Barron, John A; Baldauf, Jack G (1991): Age determinations of Paleogene Diamictites from Prydz Bay (Site 739), Antarctica, using sr isotopes of mollusks and biostratigraphy of microfossils (diatoms and coccoliths). In: Barron, J; Larsen, B; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 119, 739-745

Hans R Thierstein, J Douglas MacDougall, Ellen E Martin, Birger Larsen, John A Barron & Jack G Baldauf
Age dating of Paleogene diamictites from ODP Site 739 in Prydz Bay with marine microfossils (diatoms and calcareous nannofossils) suggests the build-up of a major East Antarctic ice shield in latest Eocene to earliest Oligocene time, about 35-38 m.y. ago. Strontium isotopic analyses of small mollusk remains found within these diamictites, however, yield younger ages ranging from 29 to 23 Ma (i.e., latest early Oligocene to earliest Miocene). These age discrepancies could be caused by...

Vegetation community and geochemistry in the Uummannaq District, West Greenland, supplement to: Lepping, Ortrun; Daniëls, Frederikus J A (2007): Phytosociology of beach and salt marsh vegetation in northern West Greenland. Polarforschung, 76(3), 95-108

Ortrun Lepping & Frederikus J A Daniëls
Beach and salt marsh vegetation of the Uummannaq District, northern West Greenland (c. 70°15' N – 72° N, 49° W – 54° W) was studied 1998 according to the Braun-Blanquet phytosociological approach. Habitat analyses included soil chemistry. Such vegetation locally occurs and is not developed over extensive areas. On gravely stony beaches a Mertensia maritima ssp. maritima community occurs, while a Honckenya peploides var. diffusa community is confined to sandy beaches. The association Honckenyo diffusae-Elymetum...

Carbonate preservation of sediment cores from the Great Bahama Bank, supplement to: Schwarz, Johanna (2007): Carbonate preservation in Pliocene to Holocene periplatform sediments (Great Bahama Bank, Florida Straits). PhD Thesis, Elektronische Dissertationen an der Staats- und Universitätsbibliothek Bremen, Germany

Johanna Schwarz
The oceanic carbon cycle mainly comprises the production and dissolution/ preservation of carbonate particles in the water column or within the sediment. Carbon dioxide is one of the major controlling factors for the production and dissolution of carbonate. There is a steady exchange between the ocean and atmosphere in order to achieve an equilibrium of CO2; an anthropogenic rise of CO2 in the atmosphere would therefore also increase the amount of CO2 in the ocean....

Geochemistry of gas hydrates of DSDP Hole 84-570, supplement to: Kvenvolden, Keith A; Claypool, George E; Threlkeld, Charles N; Sloan, E Dendy (1984): Geochemistry of a naturally occurring massive marine gas hydrate. Organic Geochemistry, 6, 703-713

Keith A Kvenvolden, George E Claypool, Charles N Threlkeld & E Dendy Sloan
During Deep Sea Drilling Project (DSDP) Leg 84 a core 1 m long and 6 cm in diameter of massive gas hydrate was unexpectedly recovered at Site 570 in upper slope sediment of the Middle America Trench offshore of Guatemala. This core contained only 5-7% sediment, the remainder being the solid hydrate composed of gas and water. Samples of the gas hydrate were decomposed under controlled conditions in a closed container maintained at 4°C. Gas...

Total organic carbon, delta13C, biomarker, gas compilations and hopanoids analysis from IODP Sites 307-U1317 and 307-U1318, supplement to: Mangelsdorf, Kai; Zink, Klaus-Gerhard; di Primio, Rolando; Horsfield, Brian (2011): Microbial lipid markers within and adjacent to Challenger Mound in the Belgica carbonate mound province, Porcupine Basin, offshore Ireland (IODP Expedition 307).

During the Integrated Ocean Drilling Program (IODP) Expedition 307 for the first time a cold-water coral carbonate mound was drilled down through its base into the underlying sediments. In the current study, sample material from within and below Challenger Mound, located in the Belgica carbonate mound province in the Porcupine Basin offshore Ireland, was investigated for its distribution of microbial communities and gas composition using biogeochemical and geochemical approaches to elucidate the question on the...

Humic acids in bottom sediments of the Western Pacific, supplement to: Vasilevskaya, N A; Golyashin, V N; Denisenko, N M; Maksimov, O B (1977): Chemical study of humic acids in Western Pacific bottom sediments. Oceanology, 17(3), 300-307

N A Vasilevskaya, V N Golyashin, N M Denisenko & O B Maksimov
Elemental composition, functional groups, and molecular mass distribution were determined in humic acids from the Western Pacific abyssal and coastal bottom sediments. Humic acid structure was studied by oxidative degradation with alkaline nitrobenzene and potassium permanganate, p-coumaric, guaiacilic, and syringilic structural units typical for lignin of terrestrial plants were identified in humic acids by chromatographic analysis of oxidation products. Polysubstituted and polycondensed aromatic systems with minor proportion of aliphatic structures were basic structural units of...

Heat flow in the Black and Mediterranean seas, supplement to: Zolotarev, Vladimir G; Sochel'nikov, V V; Malovitskiy, Ya P (1979): Results of heat-flow measurements in the Black and Mediterranean Sea basins. Oceanology, 19(6), 701-704

Vladimir G Zolotarev, V V Sochel'nikov & Ya P Malovitskiy
Results of heat-flow measurements in the western Black Sea and within the African-Sicilian region of the Mediterranean Sea are presented. New data reveal a well-defined correlation with the deep-seated geologic structure of the regions examined. A heat-flow anomaly within the Pantelleria graben, in the authors' opinion, is a consequence of connective heat transfer along channels of disjunctive faults.

Calcareous nannofossils of ODP Holes 114-699A and 114-700B, supplement to: Crux, Jason A (1991): Calcareous nannofossils recovered by Leg 114 in the subantarctic South Atlantic Ocean. In: Ciesielski, PF; Kristoffersen, Y; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 114, 155-177

Jason A Crux
Ocean Drilling Program (ODP) Leg 114 recovered nannofossil-bearing sediments from seven sites in the high latitudes of the South Atlantic Ocean.Cretaceous sections were recovered from Sites 698 and 700, located on the Northeast Georgia Rise and its lower flanks, respectively. These contain distinctive high-latitude nannofossil floras similar to those from high-latitude areas of the Northern Hemisphere. Most of the biostratigraphic datums used to date the upper Campanian to Maestrichtian interval appear to lie at approximately...

Late Miocene to Quaternary planktonic foraminifera of ODP SIte 114-704, supplement to: Brunner, Charlotte A (1991): Latest Miocene to Quaternary biostratigraphy and paleoceanography, Site 704, subantarctic South Atlantic Ocean. In: Ciesielski, PF; Kristoffersen, Y; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 114, 201-215

Charlotte A Brunner
The planktonic foraminiferal zonation of Jenkins and Srinivasan (1986), which was defined for the southwestern sector of the temperate South Pacific Ocean, was successfully extended to the temperate sequences at Site 704. The zonation is based on first and last appearances of globorotalids, principally Globoconella species, which are indigenous to temperate surface-water masses. Most of the first and last appearances at ODP Site 704 are diachronous with those in the warmer temperate to subtropical South...

On the base of detailed studies in the Keret' and Kem' estuaries (Karelian coast of the White Sea) in 2000-2003 a comparative analysis has been carried out. It includes: salinity and freshening of the water column, variations of suspended matter concentration and its chemical composition, current velocity and zooplankton species composition during flood- and ebb tides.

Plio-Pleistocene benthic foraminifera of the Tyrrhenian Sea, supplement to: Sprovieri, Rodolfo; Hasegawa, Shiro (1990): Plio-Pleistocene benthic foraminifera stratigraphic distribution in the deep-sea record of the Tyrrhenian Sea (ODP Leg 107). In: Kastens, KA; Mascle, J; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 107, 429-459

Rodolfo Sprovieri & Shiro Hasegawa
Benthic foraminifers from Site 652, Site 653 (Hole 653A), and Site 654 of Leg 107 (Tyrrhenian Sea, Western Mediterranean), which penetrated with more or less good recovery the Plio-Pleistocene stratigraphic interval, were studied in a total of 699 close-spaced samples. A total number of 269 species have been classified and their quantitative distribution in each sample is reported. The benthic foraminifers assemblage is more diversified in Site 654, less diversified in Site 652. Less than...
