Geochemistry of sediments and kerogenes of ODP Hole, supplement to: Katz, Barry J (1988): Organic-geochemical character and hydrocarbon-source potential of Site 635. In: Austin, JA Jr.; Schlager, W; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 101, 381-388

Barry J Katz
The organic matter contained within a series of Albian to Cenomanian, dark gray to black marls was characterized using pyrolysis techniques and analysis (elemental and carbon isotopes) of isolated kerogens. It was concluded that this material had a marine affinity. Variations in geochemical characteristics reflect differences in the extent of preservation, rather than changes in organic provenance. These changes appear to reflect differences in water depth and the position of the depositional site relative to...

Late Quaternary sediment accumulation in the Baffin Bay, supplement to: Andrews, John T (1987): Late Quaternary marine sediment accumulation in fjord-shelf-deep-sea transects, Baffin Island to Baffin Bay. Quaternary Science Reviews, 6(3-4), 231-243

John T Andrews
Piston cores from fiords, shelf troughs, and the deep-sea off eastern Baffin Island, N.W.T., Canada, have been sampled for texture and detrital carbonate in the <2 mm fraction. The sediments consist primarily of silty clays usually containing <5% sand. Estimates are made for sediment accumulation (kg/m**2/ka) over the last ca. 10 ka. Three sets, of two cores each, lie on a fiord-shelf transect and thus define variations in sediment accumulation gradients. These continental margin data...

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.

Sedimentology on two cores from Scoresby Sund, Greenland, supplement to: Marienfeld, Peter (1992): Postglacial sedimentary history of Scoresby Sund, East Greenland. Polarforschung, 60(3), 181-195

Peter Marienfeld
Reconstruction of the postglacial palaeoenvironmental evolution was the main objective of marine geological investigations in the Scorcsby Sund fjord system. For this purpose, samples of marine sediments, taken on RV Polarstern cruises ARK-V/3b and ARK-VII/3b in 1988 and 1990, have been analysed. All investigated fjord sediments are paratills. However, remarkable changes in sediment fabric and composition occur with depth in cores. They are attributable to different modes of sediment deposition. Therefore, a subdivision of the...

Jacques Girardeau & Yves Lagabrielle
Abundant serpentinite seamounts are found along the outer high of the Mariana forearc at the top of the inner slope of the trench. One of them, Conical Seamount, was drilled at Sites 778, 779, and 780 during Leg 125.The rocks recovered at Holes 779A and 780C, respectively, on the flanks and at the summit of the seamount, include moderately serpentinized depleted harzburgites and some dunites. These rocks exhibit evidence of resorption of the orthopyroxene, when...

Age determinations of rocks from Vestfjella and Ahlmannryggen in Antarctica, supplement to: Peters, Matthias; Lippolt, Hans Jürgen; Rittmann, Ursula; Weber, Klaus (1989): Field relations, petrography and K-Ar Age determinations on Magmatic Rocks from Neuschwabenland, Antarctica. Polarforschung, 59(1/2), 35-44

Matthias Peters, Hans Jürgen Lippolt, Ursula Rittmann & Klaus Weber
The Proterozoic country rock at Ahlmannryggen consists of flat lying basaltic lo andesitic lava flows and sedimentary rocks intruded by dioritic sills (Borgmassivet Intrusives). The suites display a typical platform cover. K-Ar age determinations gave maximum ages of about 1200 Ma on the magmatic rocks. All these suites were intruded bv Proterozoic dikes dated also at about 1200 Ma. Localiy the Proterozoic rocks have a slaty cleavage grading into mylonitic texture which strike parallel to...

Hydrocarbons in the surface microlayer and bottom sediments of the Black Sea, supplement to: Chernova, Tatyana G (1993): Hydrocarbon associations in the ecosystem of the Black Sea. Oceanology, 33(1), 67-72

Tatyana G Chernova
Data on concentrations and molecular structure of paraffin hydrocarbons and polycyclic aromatic hydrocarbons (PAHs) present in dissolved and particulate forms in the surface microlayer and in bottom sediments of the inshore and central parts of the Black Sea are presented. Distribution of hydrocarbons in these regions is chiefly governed by the independent geochemical background distribution. Industrial pollutions play a noticeable role in the northwestern and southeastern zones of the basin and that is expressed by...

Stable oxygen and carbon isotopes from ODP sites on Maud Rise and Kerguelen Plateau, supplement to: Mackensen, Andreas; Ehrmann, Werner (1992): Middle Eocene through early Oligocene climate history and paleoceanography in the Southern Ocean: Stable oxygen and carbon isotopes from ODP Sites on Maud Rise and Kerguelen Plateau.

At both sites we recovered continuous core from fairly complete Cenozoic and Cretaceous sequences; the Cretaceous sequence is 790 m thick in Site...

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...

Sedimentary history and chemical characteristics of clay minerals from the Bengal Fan, supplement to: Aoki, Saburo; Kohyama, Norihiko; Ishizuka, Toshio (1991): Sedimentary history and chemical characteristics of clay minerals in cores from the distal part of the Bengal Fan (ODP 116). Marine Geology, 99(1-2), 175-185

Saburo Aoki, Norihiko Kohyama & Toshio Ishizuka
The purpose of this study is to clarify the sedimentary history and chemical characteristics of clay minerals found in sediments deposited in the distal part of the Bengal Fan since the Himalayas were uplifted 17 m.y. ago. A total of seventy-eight samples were collected from three drilled cores which were to be used for the clay mineral analyses by means of XRD and ATEM. The results obtained from the analyses show that individual clay mineral...

Composition and sorption capacity of oceanic and marine ferromanganese nodules, supplement to: Novikov, Georgy V; Baturin, Gleb N (1997): Sorption ability of oceanic and marine ferromanganese nodules and crusts of different chemical and mineralogical composition. Translated from Okeanologiya, 1997, 37(4), 525-531, Oceanology, 37(4), 472-478

Georgy V Novikov & Gleb N Baturin
Experimental data obtained show that oceanic and marine ferromanganese nodules and crusts are natural ion-exchangers. Exchange capacity of oceanic ferromanganese aggregates is much higher than that of shallow-water marine ones, whereas reactivities of exchange cations (Na, K, Ca, and Mg) are almost equal in both.

Mineralogy and geochemistry of aerosols from the Western Pacific, supplement to: Lukashin, Vyacheslav N; Shevchenko, Vladimir P; Lisitzin, Alexander P; Serova, Valentina V; Ivanov, Georgy V (1996): The distribution, matter, and chemical composition of aerosols over the Western Pacific. Translated from Okeanologiya, 1996, 36(2), 288-298, Oceanology, 36(2), 267-276

Vyacheslav N Lukashin, Vladimir P Shevchenko, Alexander P Lisitzin, Valentina V Serova & Georgy V Ivanov
Aerosols collected by net method over the Western Pacific were investigated. Distribution of eolian material, its mineral and chemical compositions are controlled by the climatic and circumcontinental zonalities. It was stated that Fe and Mn were bound with mineral components of aerosols, while trace elements are bound with organogenic matter. Fluxes of aerosols and their components on the ocean surface were determined.

Chemical composition of waters from the Black Sea, supplement to: Danilenko, A F; Ryabinin, A I (1986): Sulfates in Black Sea waters. Oceanology, 26(6), 710-716

A F Danilenko & A I Ryabinin
Concentrations of sulfate ions at three depths in the water column of the Black Sea were studied during cruises of the GOIN (State Oceanographic Institute) Sevastopol' Division in 1983 and 1985. Results were compared with data from earlier studies. Obtained data indicate pronounced lateral and temporal variation in the SO4/Cl ratio.
