Appropriate field data are required to check the reliability of hydrodynamic models simulating the dispersion of soluble substances in the marine environment. This study deals with the collection of physical measurements and soluble tracer data intended specifically for this kind of validation. The intensity of currents as well as the complexity of topography and tides around the Cap de La Hague in the center of the English Channel makes it one of the most difficult...

Age determination of three sediment cores from the Eurasian continental margin, supplement to: Knies, Jochen; Nowaczyk, Norbert R; Müller, Claudia; Vogt, Christoph; Stein, Ruediger (2000): A multiproxy approach to reconstruct the environmental changes along the Eurasian continental margin over the last 150 000 years. Marine Geology, 163(1-4), 317-344

Jochen Knies, Norbert R Nowaczyk, Claudia Müller, Christoph Vogt & Ruediger Stein
Sediment cores located along the Eurasian continental margin (Arctic Ocean) have been studied to reconstruct the environmental changes in terms of waxing and waning of the Barents/Kara Sea ice-sheets, Atlantic water inflow, and sea-ice distribution over the last 150 kyr. The stratigraphy of the cores is based on stable oxygen isotopes, AMS 14C, and paleomagnetic data. We studied variations in marine and terrigenous input by a multiproxy approach, involving direct comparison of sedimentological and organo-geochemical...

n-Alkanes and lignin in bottom sediments of the West European Basin (area of the battleship Bismark wreck site), supplement to: Peresypkin, Valery I; Romankevich, Evgeny A; Belyaev, Nikolay A (2003): Contents and molecular composition of alkane-naphthene hydrocarbons, lignin and lignin-derived phenols in the bottom sediments from the West-European Basin. Translated from Okeanologiya, 2003,43(3), 371-382, Oceanology, 43(3), 347-358

Composition of bitumen in the organic matter of Black Sea sediments from DSDP Hole 42-379B, supplement to: Geodekyan, Artyom A; Chernova, Tatyana G; Ul'mishek, Georgy F; Bokovoy, A P; Fedorova, M S (1977): Bitumoids in the organic matter of Black Sea sediments (based on Deep-Sea Drilling data). Oceanology, 17(5), 536-540

Artyom A Geodekyan, Tatyana G Chernova, Georgy F Ul'mishek, A P Bokovoy & M S Fedorova
Bituminologic analysis of sediment cores from the Black Sea (water depth up to 2000 m, drilling depth up to 625 m) has revealed all components typical for fossilized rocks, viz. hydrocarbons, resins, asphaltenes, and insoluble matter. Proportions of these components, their composition and properties do not display any dependence on depth in hole and seem to be governed by composition of organic matter and conditions and degree of its transformation at early stages of lithogenesis.

Age model and grain size distribution of the fine fraction of ODP Site 114-704, supplement to: Mienert, Jürgen; Nobes, David C (1991): Physical properties of sediments beneath Polar Front upwelling regions in the subantarctic South Atlantic (Hole 704A). In: Ciesielski, PF; Kristoffersen, Y; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 114, 671-683

Jürgen Mienert & David C Nobes
The physical properties of sediments beneath an upwelling area in the southern part of the Atlantic Ocean (ODP Hole 704A) were investigated. Highly significant correlations characterize the relationship of carbonate content to bulk density (R = 0.85), carbonate content to porosity (R = 0.84), and carbonate content to impedance (R = 0.84). No relationship exists between carbonate content and compressional-wave velocity (R = 0.24), indicating that amplitude variations in impedance are primarily controlled by variations...

Grain size composition of sediments from the Theresa Clavenes Bay, Laptev Sea, supplement to: Alekseeva, Tatyana N; Sval'nov, Vyacheslav N (2000): On the techniques for grain-size analysis of fine-grained sediments. Translated from Okeanologiya, 2000, 40(2), 304-312, Oceanology, 40(2), 281-288

Tatyana N Alekseeva & Vyacheslav N Sval'nov
A comparative analysis of grain size composition of shallow water terrigenous sediments from the southeastern Laptev Sea was carried out using methods developed by V.P. Petelin and A. Atterberg. Potential of these methods and possibilities of improvement of domestic techniques for grain size analysis are discussed.

This data report tabulates results of X-ray fluorescence analysis of sediments from three sites drilled during Ocean Drilling Program Leg 124. Two of these sites were drilled in the abyssal plain of the Celebes (767) and Sulu (768) seas, in water depths of 4905 and 4385 m, respectively. The seismic records at these sites reveal a sedimentary section that appears complete enough to obtain a good stratigraphic history of the basins, one of the main...

Short-term spectral analysis of ODP Hole 114-704B, supplement to: Mwenifumbo, C J; Blangy, J P (1991): Short-Term spectral analysis of downhole logging measurements from Site 704. In: Ciesielski, PF; Kristoffersen, Y; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 114, 577-585

C J Mwenifumbo & J P Blangy
Short-term spectral analysis was carried out on geochemical logging data from ODP Site 704. The FFT was used to compute the amplitude spectra of short-term overlapping segments to produce depth-period-amplitude spectrograms of the logging data. The spectrograms provided a means of evaluating the significance of the observed periodic components. The periodic components that were consistently present and prominent across a given record interval were considered to be significant. Changes in the spectrogram characteristics seem to...

Biomass of picophytoplankton in the Black Sea in winter 1991, supplement to: Kokurkina, E N; Mikaelyan, A S (1994): Composition and distribution of picophytoplankton in the open area of the Black Sea in winter. Oceanology, 34(1), 60-65

E N Kokurkina & A S Mikaelyan
Studies of picophytoplankton were carried out in the open Black Sea from February to April 1991 with concomitant blooming of diatoms. During this period cyanobacteria predominated in picoplankton averaging 98.8% of total picophytoplankton abundance and 95% of total picoplankton biomass. In February number of cells reached 1.5x10**9 per liter in the East Black Sea. Picoplankton biomass decreased during the observation period. From February to March biomass varied from 452 to 4918 mg/m**2 (av. 1632 mg/m**2),...

Cs-137 and Co-60 isotopes and sedimentation rates in Late Holcene sediments from the Northwestern Black Sea, supplement to: Domanov, Mikhail M; Kontar', Evgeny A; Kosyan, Ruben D; Sapozhnikov, Dmitry A; Shimkus, Kazimir M (1996): Anthropogenic radionuclides in Northwestern Black Sea sediments. Translated from Okeanologiya, 1996, 36(4), 550-555, Oceanology, 36(4), 516-520

Mikhail M Domanov, Evgeny A Kontar', Ruben D Kosyan, Dmitry A Sapozhnikov & Kazimir M Shimkus
Results of measurements of Cs-137 and Co-60 concentrations in bottom sediments of the Northwestern Black Sea indicate inhomogenity of their distribution both over the studied area and along sediment cores. Intermittency of sediment layers with different concentration of radionuclides in the cores reflects active horizontal movements and redistribution of sediments on the shelf and continental slope. As a result sediment layers dated by the Chernobyl mark as seven years old were found in the 5-7...

First-year and second-year snow properties on sea ice in the Weddell Sea during POLARSTERN cruise ANT-XXII/2 (ISPOL) during the drift, supplement to: Nicolaus, Marcel; Haas, Christian; Willmes, Sascha (2009): Evolution of first-year and second-year snow properties on sea ice in the Weddell Sea during spring-summer transition. Journal of Geophysical Research: Atmospheres, 114, D17109

Marcel Nicolaus, Christian Haas & Sascha Willmes
Observations of snow properties, superimposed ice, and atmospheric heat fluxes have been performed on first-year and second-year sea ice in the western Weddell Sea, Antarctica. Snow in this region is particular as it does usually survive summer ablation. Measurements were performed during Ice Station Polarstern (ISPOL), a 5-week drift station of the German icebreaker RV Polarstern. Net heat flux to the snowpack was 8 W/m**2, causing only 0.1 to 0.2 m of thinning of both...

Oligocene strontium isotope stratigraphy of Indian Ocean sediments, supplement to: Pospichal, James J; Wei, Wuchang; Wise, Sherwood W (1991): Data report: Indian Ocean Oligocene strontium isotope stratigraphy, Legs 119-121, Kerguelen Plateau and Ninetyeast Ridge. In: Weissel, J; Peirce, J; Taylor, E; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 121, 921-930

James J Pospichal, Wuchang Wei & Sherwood W Wise
Strontium isotope (87Sr/86Sr) ages have been established for Oligocene samples of Leg 119 Site 744, Leg 120 Sites 747 and 748, and Leg 121 Sites 756 and 757. Ages were determined using the strontium isotope age equation of Miller et al. (1988) and preliminary correlations have been made with available nannofossil biostratigraphy. The strontium isotope ages calculated here augment biostratigraphy, which for the Oligocene is characterized by long biozones, and provide additional detail where the...

Sedimentological and paleontological anaylsis of a profile from Lake Ohrid, supplement to: Wagner, Bernd; Lotter, André F; Nowaczyk, Norbert R; Reed, Jane M; Schwalb, Antje; Sulpizio, Roberto; Valsecchi, Verushka; Wessels, Martin; Zanchetta, Giovanni (2009): A 40,000-year record of environmental change from ancient Lake Ohrid (Albania and Macedonia). Journal of Paleolimnology, 41, 407-430

Bernd Wagner, André F Lotter, Norbert R Nowaczyk, Jane M Reed, Antje Schwalb, Roberto Sulpizio, Verushka Valsecchi, Martin Wessels & Giovanni Zanchetta
Lake Ohrid is considered to be of Pliocene origin and is the oldest extant lake in Europe. A 1,075- cm-long sediment core was recovered from the southeastern part of the lake, from a water depth of 105 m. The core was investigated using geophysical, granulometric, biogeochemical, diatom, ostracod, and pollen analyses. Tephrochronology and AMS radiocarbon dating of plant macrofossils reveals that the sediment sequence spans the past ca. 39,500 years and features a hiatus between...

Composition of micronodules and host sediments from the Guatemala Basin, supplement to: Gorshkov, Anatoly I; Sval'nov, Vyacheslav N; Sivtsov, Alexander V; Ivlev, Pavel A; Uspenskaya, Tatyana Y (1996): Mineralogy of manganese micronodules from the Guatemala Basin. Translated from Okeanologiya, 1996, 36(1), 112-118, Oceanology, 36(1), 102-108

Anatoly I Gorshkov, Vyacheslav N Sval'nov, Alexander V Sivtsov, Pavel A Ivlev & Tatyana Y Uspenskaya
A complex of mineralogical techniques used in studies of near-surface layer hemipelagic sediments indicates that disordered todorokite and hexagonal birnessite dominate in manganese micronodules, whereas hexagonal birnessite is the main phase of micronodules from miopelagic sediments. Content of todorokite increases downward through the miopelagic sedimentary sequence; this can be reasonably explained by transformations of some other manganese minerals to todorokite. Occurrence of several manganese minerals in studied samples may reflect temporal and lateral variations in...
