Aim To test whether the radiation of the extremely rich Cape flora is correlated with marine-driven climate change.Location Middle to Late Miocene in the south-east Atlantic and the Benguela Upwelling System (BUS) off the west coast of South Africa.Methods We studied the palynology of the thoroughly dated Middle to Late Miocene sediments of Ocean Drilling Program (ODP) Site 1085 retrieved from the Atlantic off the mouth of the Orange River. Both marine upwelling and terrestrial...

Geochemistry and mineralogy of sediments from the Atlantis II Fracture Zone, supplement to: Van der Flier-Keller, Eileen (1991): Geochemistry and mineralogy of sediments, Atlantis II Fracture Zone, Southwest Indian Ocean. In: Von Herzen, RP; Robinson, PT; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 118, 145-151

Eileen Van der Flier-Keller
Thirteen sediment samples, including calcareous ooze, sandy clay, volcanic sand, gravel, and volcanic breccia, from Ocean Drilling Program (ODP) Sites 732B, 734B, 734G and Conrad Cruise 27-9, Station 17, were examined. Contents of major and trace elements were determined using XRF or ICP (on samples <0.5 g). Determinations of rare earth elements (REE) were performed using ICP-MS. Mineralogy was determined using XRD.On the basis of the samples studied, the sediments accumulating in the Atlantis II...

Composition of Fe-Mn nodules and crusts from the Cape Basin, supplement to: Levitan, Mikhail A (1988): Iron-manganese nodules of the Cape Basin. Oceanology, 28(3), 359-362

Mikhail A Levitan
Facies zonation of the Cape basin with respect to Fe-Mn nodules based on data from Cruise 43 of R/V Akademik Kurchatov and published data is presented. Three facies regions are distinguished: the southern end of the Walvis Ridge and seamounts, the continental slope of the Southwest Africa and the deep-water Cape Basin. Iron-manganese nodules in the first of these areas are predominantly sedimentary, those in the second area are diagenetic and those in the third...

Chemistry of gabbroic rocks of ODP Hole 118-735B, supplement to: Hébert, Rejean; Constantin, Marc; Robinson, Paul T (1991): Primary mineralogy of Leg 118 gabbroic rocks and their place in the spectrum of oceanic mafic igneous rocks. In: Von Herzen, RP; Robinson, PT; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 118, 3-20

Rejean Hébert, Marc Constantin & Paul T Robinson
We present results of a microprobe investigation of fresh and least-deformed and metamorphosed gabbroic rocks from Leg 118, Hole 735B, drilled on the east side of the Atlantis II Fracture Zone, Southwest Indian Ridge. This rock collection comprises cumulates ranging from troctolites to olivine-gabbro and olivine-gabbronorite to ilmenite-rich ferrogabbros and ferrogabbronorites. As expected, the mineral chemistry is variable and considerably expands the usual oceanic reference spectrum. Olivine, plagioclase, and clinopyroxene are present in all the...

Gas hydrates of the Gulf of Mexico, supplement to: Brooks, James M; Cox, H Benjamin; Bryant, William; Kennicutt, Mahlon C; Mann, Robert G; McDonald, Thomas J (1985): Association of gas hydrates and oil seepage in the Gulf of Mexico. Organic Geochemistry, 10(1-3), 221-234

James M Brooks, H Benjamin Cox, William Bryant, Mahlon C Kennicutt, Robert G Mann & Thomas J McDonald
Gas hydrates were recovered from eight sites on the Louisiana slope of the Gulf of Mexico. The gas hydrate discoveries ranged in water depths from 530 to 2400 m occurring as small to medium sized (0.5-50 mm) nodules, interspersed layers (1-10 mm thick) or as solid masses (> 150 mm thick). The hydrates have gas:fluid ratios as high as 170:1 at STP, C1/(C2 + C3) ratios ranging from 1.9 to > 1000 and d13C ratios...

C1-C8 hydrocarbons in marine sediments, supplement to: Whelan, Jean K; Hunt, John M; Jasper, John P; Huc, Alain Y (1984): Migration of C1-C8 hydrocarbons in marine sediment. Organic Geochemistry, 6, 683-694

Jean K Whelan, John M Hunt, John P Jasper & Alain Y Huc
Light hydrocarbon (C1-C8) profiles are compared for three wells of varying maturities: two immature DSDP wells (Site 397 near the Canary Islands and Site 530A near the Walvis Ridge in the south-east Atlantic) and a mature well, the East Cameron well in the Texas Gulf Coast. Primary migration of C1 and C2 appears to be occurring in all of the sedimentary rocks examined. Primary migration of C3+ components becomes important only as fine-grained sedimentary rocks...

Seismic velocities and elastic properties of gabbroic rocks from ODP Hole 118-735B, supplement to: Iturrino, Gerardo J; Christensen, Nikolas I; Kirby, Stephen; Salisbury, Matthew H (1991): Seismic velocities and elastic properties of oceanic gabbroic rocks from Hole 735B. In: Von Herzen, RP; Robinson, PT; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 118, 227-244

Gerardo J Iturrino, Nikolas I Christensen, Stephen Kirby & Matthew H Salisbury
The nearly continuous recovery of 0.5 km of generally fresh, layer 3 gabbroic rocks at Hole 735B, especially near the bottom of the section, presents scientists an unusual opportunity to study the detailed elastic properties of the lower oceanic crust. Extending compressional-wave and density shipboard measurements at room pressure, Vp and Vs were measured at pressures from 20 to 200 MPa using the pulse transmission method. All of the rocks exhibit significant increases in velocity...

Stable isotope record and aklenonen index of MIS 11 sediments, supplement to: Dickson, Alexander J; Beer, Christopher J; Dempsey, Ciara; Maslin, Mark A; Bendle, James A; McClymont, Erin L; Pancost, Richard D (2009): Oceanic forcing of the Marine Isotope Stage 11 interglacial. Nature Geoscience, 2, 428-433

Alexander J Dickson, Christopher J Beer, Ciara Dempsey, Mark A Maslin, James A Bendle, Erin L McClymont & Richard D Pancost
The interglacial known as Marine Isotope Stage 11 has been proposed to be analogous to the Holocene, owing to similarities in the amplitudes of orbital forcing. It has been difficult to compare the periods, however, because of the long duration of Stage 11 and a lack of detailed knowledge of any extreme climate events that may have occurred. Here we use the distinctive phasing between seasurface temperatures and the oxygen-isotope records of benthic foraminifera in...

Pollen record in bones from Barsbek, northern Germany

Rudolf Schütrumpf
Als im Frühsommer 1949 die ersten Pferdeschädel und Hundeknochen als Streufunde aus dem Barsbeker Moor bekannt wurden, war es wünschenswert, mit Hilfe der Pollenanalyse eine zeitliche Zuordnung zu versuchen. Auf diese Weise konnte unter Umständen wieder ein prähistorischer Horizont pollenanalytisch fixiert werden, da u.a. auch datierbare Keramikreste aus der römischen Kaiserzeit gefunden wurden. Die Analyse des aus der Stirnhöhle zweier Pferdeschädel entnommenen Materials ergab die beiden obersten in der Tabelle verzeichneten Pollenspektren. Bei der Untersuchung...

Investigation of pingos in Kuganguaq delta on Disko Island, supplement to: Yoshikawa, Kenji; Nakamura, Toshio; Igarashi, Yaeko (1996): Growth and collapse history of Pingos, Kuganguaq, Disko Island, Greenland. Polarforschung, 64(3), 109-113

Kenji Yoshikawa, Toshio Nakamura & Yaeko Igarashi
The growth and collapse history of two pingos located approximately 18 m a.s.l, and 35 m a.s.l. in Kuganguag, Disko lsland, west-central Greenland were examined. The pingos of this area were formed on Tertiary basalt rocks. One of the pingos is located in the middle of an alluvial fan, the other is on a river bed. Both have already collapsed. The pingo on the river bed had already collapsed at least 3545±60 year BP (14C...

Mineralogy of silts from the Bengal Fan, supplement to: Yokoyama, Kazumi; Amano, Kazuo; Taira, Asahiko; Saito, Yasuji (1990): Mineralogy of silts from the Bengal Fan. In: Cochran, JR; Stow, DAV; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 116, 59-73

Kazumi Yokoyama, Kazuo Amano, Asahiko Taira & Yasuji Saito
Early Miocene to Quaternary sediments drilled from the Bengal Fan are divided into six zones by modal proportions of heavy minerals. The sediments were mostly derived from the Himalayas. Detritus from the Indian subcontinent is found sporadically in clay-rich sediments that were deposited during periods of slow sedimentation, when the deep-sea channel migrated away from the drilled sites.The oldest sediments, ranging from 17 to about 15 Ma, were derived mostly from the Precambrian and Paleozoic...

Fluorescence of dissolved organic matter un marine sediments, supplement to: Chen, Robert F; Bada, Jeffrey L (1994): The fluorescence of dissolved organic matter in porewaters of marine sediments. Marine Chemistry, 45(1-2), 31-42

Robert F Chen & Jeffrey L Bada
The fluorescence of porewaters from marine sediment cores from six different areas was measured. In most cases, fluorescence was affected primarily by the diagenesis of organic carbon first through sulfate reduction and subsequently by methane generation. Typically, fluorescence, dissolved organic carbon (DOC), absorbance, alkalinity, and ammonium ion concentrations correlate quite well, increasing in the upper sections of anoxic sediments and co-varying in deeper sections of these cores. The good correlation of DOC with fluorescence in...

Biomarkers of early Aptian sediments of the Shatsky Rise, supplement to: Dumitrescu, Mirela; Brassell, Simon C (2005): Biogeochemical assessment of sources of organic matter and paleoproductivity during the early Aptian Oceanic Anoxic Event at Shatsky Rise, ODP Leg 198. Organic Geochemistry, 36(7), 1002-1022

Mirela Dumitrescu & Simon C Brassell
This study investigates organic-rich sedimentary sequences deposited during the early Aptian Oceanic Anoxic Event (OAE1a) at Sites 1207 and 1213 on Shatsky Rise (ODP Leg 198) in the west-central Pacific. Biomarker analyses provide evidence of the algal and bacterial origin of organic matter (OM) in these sediments where the abundance of steroidal components, particularly sterenes and sterones, suggests that the OM includes major contributions from eukaryotic sources in an environment characterized by high phytoplankton productivity....

Physiological and biochemical characteristics of Calanoides carinatus in waters off the coast of Namibia, supplement to: Kosobokova, Ksenia N; Drits, Alexander V; Krylov, P I (1988): Physiological and biochemical characteristics of Calanoides carinatus in waters on an upwelling off the coast of Namibia. Oceanology, 28(3), 375-379

Ksenia N Kosobokova, Alexander V Drits & P I Krylov
Biochemical composition, feeding and oxygen uptake rate of mass planktic copepod Calanoides carinatus were studied off the coast of Namibia in January 1986. Population of this species in the area had two parts: the surface group inhabiting the 0-100 m layer and the deep part inhabiting depths greater than 200 m. Individuals in the surface and deep parts of the population differed in food content of guts, lipid content of bodies, oxygen uptake rate and...

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.

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...

Geochemistry of interstitial waters from ODP Leg 115 sites, supplement to: Boulègue, Jacques (1990): Interstitial waters geochemistry, Leg 116. In: Cochran, JR; Stow, DAV; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 116, 421-423

Jacques Boulègue
As a part of the shipboard scientific program, interstitial waters were routinely analyzed for pH, alkalinity, salinity, chlorinity, calcium, and magnesium during Leg 116. Unfortunately, the tables containing these data for Sites 718 and 719 were inadvertently omitted from the Initial Results volume (Cochran, Stow et al., 1989, doi:10.2973/odp.proc.ir.116.1989). The missing data are presented here (Tables 1-3) along with the Site 717 data, reproduced for completeness.

Abundance and biomass of the benthic infauna of the North Sea, supplement to: Aldridge, John N; Bergman, Magda J N; Bolam, T; Craeymeersch, Johan A; Degraer, Steven; Duineveld, Gerard C A; Eggleton, J D; Goethals, P; Hillewaert, H; Irion, G; Kershaw, P J; Kröncke, Ingrid; Lavaleye, Marc; Mason, Claire; Rachor, Eike; Rees, H L; Reiss, H; Rumohr, Heye; Schratzberger, M; Smith, R; Vanden Berghe, E; van Hoey, G; Vincx, Magda; Willems, W (2007): Structure and dynamics of the North Sea benthos. Ices Cooperative Research Report-Rapport des Recherches Collectives, 288, 265 pp

Anita Künitzer, D J Basford, Johan A Craeymeersch, Jean-Marie Dewarumez, Jürgen Dörjes, Gerard C A Duineveld, Anastasios Eleftheriou, Carlo H R Heip, P M J Herman, P Kingston, U Niermann, Eike Rachor, Heye Rumohr & Peter A W J de Wilde
In 1986 participants of the Benthos Ecology Working Group of ICES conducted a synoptic mapping of the infauna of the southern and central North Sea. Together with a mapping of the infauna of the northern North Sea by Eleftheriou and Basford (1989, doi:10.1017/S0025315400049158) this provides the database for the description of the benthic infauna of the whole North Sea in this paper. Division of the infauna into assemblages by TWINSPAN analysis separated northern assemblages from...

Physical properties, grain size distribution and clay mineralogy of ODP Leg 117 sites, supplement to: Callaway, J Sybil; Busch, William H (1991): Burial transformation of sediment fabric at sites in the western Arabian Sea. In: Prell, WL; Niitsuma, N; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 117, 221-238

J Sybil Callaway & William H Busch
The fabric of sediments recovered at sites drilled on the Indus Fan, Owen Ridge, and Oman margin during Ocean Drilling Program Leg 117 was examined by scanning electron microscopy to document changes that accompany sediment burial. Two sediment types were studied: (1) biogenic sediments consisting of a variety of marly nannofossil and nannofossil oozes and chalks and (2) terrigenous sediments consisting of fine-grained turbidites deposited in association with the Indus Fan. Biogenic sediments were examined...

Planktonic foraminifera of ODP Site 117-722, supplement to: Kroon, Dick; Steens, Tineke N F; Troelstra, Simon (1991): Onset of monsoonal related upwelling in the western Arabian Sea as revealed by planktonic foraminifers. In: Prell, WL; Niitsuma, N; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 117, 257-263

Dick Kroon, Tineke N F Steens & Simon Troelstra
Quantitative analysis of the late Cenozoic planktonic foraminiferal record from western Arabian Sea Site 722 revealed long term trends in the history of oceanography and climate. The modern western Arabian Sea surface waters are highly influenced by the monsoonal wind system. Summer upwelling, a result of southwestern winds, occurs along the coast of Somalia which produces distinct foraminiferal assemblages which are dominated by G. bulloides d'Orbigny. Consequently, variations in the distribution record of G. bulloides...

Organic carbon, reduced sulfur, and iron in Miocene to Holocene sediments from the Oman and Beguela upwelling systems, supplement to: Emeis, Kay-Christian; Morse, John W; Mays, Linda L (1991): Organic carbon, reduced sulfur, and iron in Miocene to Holocene upwelling sediments from the Oman and Benguela upwelling systems. In: Prell, WL; Niitsuma, N; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 117, 517-527

Kay-Christian Emeis, John W Morse & Linda L Mays
We examined sediments from Neogene and Quaternary sections of the Benguela and Oman upwelling systems (DSDP Site 532, ODP Sites 723 and 722) to determine environmental and geochemical factors which control and limit pyrite formation in organic-carbon-rich marine sediments.Those samples from the upwelling sites, which contained low to moderate concentrations of total organic carbon (0.7%-3%), had C/S ratios typical of normal marine sediments, i.e., around 2.8. In these sediments, TOC availability probably limited pyrite formation....

Mineralogy and structural specification of ODP Leg 125 peridotite samples, supplement to: Girardeau, Jacques; Lagabrielle, Yves (1992): Deformation history of peridotites from Mariana Forearc, conical seamount, Leg 125. In: Fryer, P; Pearce, JA; Stokking, LB; et al. (eds.), Proceedings of the Ocean Drilling Program, Scientific Results, College Station, TX (Ocean Drilling Program), 125, 519-532

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...

Zooplankton community within the Titanic Polygon, Northwest Atlantic, summer 2003, supplement to: Vinogradov, Georgy M; Musaeva, Eteri I; D'yakonov, Vladimir Yu; Gagarin, Vladimir I (2004): Vertical distribution of zooplankton in the area of the frontal zone of the Gulf Stream and subpolar waters (Titanic test area) in the summer 2003. Translated from Okeanologiya, 2004, 44(2), 249-258, Oceanology, 44(2), 230-239

Georgy M Vinogradov, Eteri I Musaeva, Vladimir Yu D'yakonov & Vladimir I Gagarin
In summer 2003 we continued our long-term series of observations over the zooplankton community within the Titanic Polygon (area of the frontal zone of Gulf Stream and the Labrador Current) in the North Atlantic, where interaction of ecosystems of subpolar and warm waters takes place. Depending on hydrological situation occurring in the frontal zone interrelated interannual variations in abundance and biomass of plankton species including Calanus hyperboreus and mesopelagic shrimps of Acanthephyra genus were observed....

Microbiological investigations of the Canadian tundra, supplement to: Bölter, Manfred (2006): Microbiological communities and properties of arctic soils: results of the Tundra Northwest Expedition 1999 (Nunavut and Northwest Territories, Canada). Polarforschung, 73(2/3), 103-110

Manfred Bölter
Microbial communities were analyzed at 17 sites visited during the expedition Tundra Northwest 1999 (TNW-99) by microscopic analyses (epifluorescence microscopy and image analyses). The data were used to describe the communities of bacteria, fungi and algae in detail by number, biovolume and biomass. Great variability was found, which could be related to organic matter content of soils and features of vegetation patterns. The amounts (numbers and abundance) of organisms and data on microbial biomass are...

Physical properties, sedimentation rates, and accumulation rates of bottom sediments from the Laptev Sea collected during SPASIBA-91 Russian-French Program, supplement to: Kuptsov, Vladimir M; Lisitzin, Alexander P (2003): Humidity, bulk density and sedimentary matter fluxes in bottom sediments of the Laptev Sea. Translated from Okeanologoya, 2003, 43(1), 127-133, Oceanology, 43(1), 121-127

Vladimir M Kuptsov & Alexander P Lisitzin
Humidity and wet and dry bulk densities were determined for bottom sediments of the Lena River marginal filter within a 700 km section from the outer boundary of the river delta. Earlier determinations of suspended matter concentration in water, material and grain-size composition and age of sediments were made along the same section. Sediment matter fluxes (accumulation rates), their changes in space and time (about 14 ka) were inferred from measurements of physical parameters. A...
