title: (Table 1) Organic carbon contents and vitrinite reflection in sediments from DSDP Holes 63-467, 63-471, and 64-481A

description: A number of C25 and C30 highly branched isoprenoid (HBI) sulphur compounds (E.G., thiolanes, 1-oxo-thiolanes, thiophenes, and benzo[b]thiophenes) with 2,6,10,14-tetramethyl-7-(3-methylpentyl)pentadecane and 2,6,10,14,18-pentamethyl-7-(3-methylpentyl)nonadecane carbon skeletons were identified in sediments, ranging from Holocene to Upper Cretaceous. These identifications are based on mass spectral characterisation, desulphurisation, and, in some cases, by comparison of mass spectral and relative retention time data with those of authentic standards. The presence of unsaturated C25 and C30 HBI thiolanes in a Recent sediment from the Black Sea (age 3-6 ka) strongly supports their formation during early diagenesis. The co-occurrence of HBI polyenes (C25 and C30) and unsaturated HBI thiolanes (C25 and C30) possessing two double bonds less than the corresponding HBI polyenes, in this Recent sediment, testifies to the formation of unsaturated HBI thiolanes by a reaction of inorganic sulphur species with double bonds of the HBI polyenes. Furthermore, a diagenetic scheme for HBI sulphur compounds is proposed based on the identification of HBI sulphur compounds in sediment samples with different maturity levels.

title: Geochemical analyses of chert nodules and beds from deep-sea sediments (Table 1)

description: Concentrations of Fe, Mg, Ca, Sr, Mn, Zn, and other heavy metals were analyzed by atomic absorption spectrometry in 27 chert samples from the Pacific deep sea, 17 chert samples from land, and 4 associated sediments from the Pacific Ocean. Among the elements, Fe and Mg concentrations are highly correlatable as are the relationships between Ca and Sr, or between Ca and CO2. The correlation between Fe and Mg is particularly high for Pacific deep-sea flints and cherts, and for cherts of deep-sea origin from outcrops on land. Enrichments in heavy metals were recognized in some deep-sea cherts; volcanogenic cherts are enriched in Fe, a chert nodule containing basaltic fragments is enriched in Zn and Cr, and biogenically enclosed carbonates in flint nodules are enriched in Mn. The correlation of Fe and Mg and their constant ratio [Mg(%)/Fe(%)] of around 0.33 might be characteristic features in the pelagic clays contained in deep-sea flints and cherts, and the concentrations of heavy metals in them would be controlled by the concentrations of Fe-Mg correlated clays. Although the mineralogical nature of the Fe-Mg clay in deep-sea cherts was not clarified by dissolution experiments on opaline minerals in chert, the high concentrations of Fe-montmorillonite and fine-grained olivine or other ferromagnesian silicate minerals in the clay may result in the high correlations between Fe and Mg.

title: Annotated record of the detailed examination of Mn deposits from R.R.S. "Discovery" Cruise 33 stations

description: The American Deep Sea Drilling Project (JOIDES) has agreed to drill several holes into the deep sea sediments at sites in the NE Atlantic suggested by UK and French scientists. These sites have been chosen on the basis of data collected over several years in the areas of Rockall, the Bay of Biscay and King's Trough. On Cruise 33 we undertook to make more detailed seismic reflection surveys of three of these sites in order to guide the choice of the exact hole position and to provide supplementary data. The following three sites were surveyed: Site A in the Hatton-Rockall Basin, Site B in Rockall Trough, Site C on the Azores-Biscay Rise. (2) The southeast end of King's Trough (Peake and Freen Deeps) was studied in detail in Cruises 4 and 11 of R. R. S. 'Discovery' in 1965 and 1966. The results of this work (Matthews et al. , 1969) were not conclusive about the origin of King's Trough. The major part of Cruise 33 was concerned, therefore, with obtaining more geological and geophysical data about King's Trough and its relationship to sea floor spreading occurring to the west on the mid-Atlantic Ridge.

title: Abundance of bacteria and endospores in surface sediments of Josephine Seamount area (Table 1)

description: During the 19th cruise of the research vessel "Meteor" between Madeira and Lisbon 260 strains of aerobic heterotrophic bacteria have been isolated from sediment samples collected from different depths. These strains have been identified mainly as members of the genera Marinovibrio, Pseudomonas, and Bacillus. The majority of bacteria isolated from shallow areas (Josephine Seamount) were sea water media requiring Marinovibrio and Pseudornonas spp. but in sediment samples taken from depths exceeding 1000 m the probably terrestrial sporeforming Bacillus spp. predominated. Further investigations in the same region during the 23rd cruise of the "Meteor" demonstrated that about 30 to 50% of the sporeforming bacteria found in the sediment samples could be isolated from dormant spores in situ. The remaining more than 50 % of sporeformers in the deep sea region examined are believed to be metabolic active cells.

title: Occurrence and activity of anammox bacteria in surface sediments of the southern North Sea

description: We investigated the occurrence and activity of anaerobic ammonia oxidation (anammox) bacteria in sandy and muddy sand sediments of the southern North Sea. The presence of anammox bacteria was established through the detection of specific phosphocholine-monoether ladderane lipids, 16S rRNA gene, and hydrazine synthase (hzsA) genes. Anammox activity was measured in intact sediment cores (in situ rate) and in sediment slurries (potential rate) as the rate of N2 evolution from 15N-labeled substrates and compared to the transcriptional activity of genes of anammox bacteria. The contribution of anammox to N2 production ranged between 0% and 29%. The potential rate of anammox agreed well with the abundance of anammox bacteria 16S rRNA and hzsA gene copies and the transcriptional activity of the anammox bacteria 16S rRNA gene. We found a higher abundance and activity of anammox bacteria in sediments with higher organic carbon content and also higher activity in summer than in winter. The abundance of anammox bacteria and their potential anammox rates were similar to those reported for other marine coastal sediments, suggesting that potentially they are important contributors to the nitrogen cycle in sandy sediments of shallow continental shelf areas.

title: Ichthyoplankton composition from SUDEPE cruise 7, Southern Brazilian Shelf, in 1976

description: The cruises of this series were carried out by the "Superintendência de Desenvolvimento da Pesca" (SUDEPE), through the "Grupo Especial para Execução de Pesquisas Marítimas e Lacustres" (GEEPMAL) from the state of Rio Grande do Sul, with support from the "Programa de Desenvolvimento Pesqueiro do Brasil" (PDP). Ichthyoplankton was obtained during 14 exploratory demersal fishing cruises, carried out in 1970, 1971 and 1976 by the Mestre Jerônimo and Cruz Del Sur Research Ships. Because they represent a continuity of sampling during the same time of year, cruises 1, 2 and 3 of 1970 were aggregated in a single cruise (SUDEPE_1, Winter), cruises 7 and 8 of 1970 (SUDEPE_2, Spring), cruises 1 and 2 of 1971 (SUDEPE_3, Winter), cruises 3 and 4 of 1971 (SUDEPE_4, Spring) , and cruises 5 and 6 of 1976 (SUDEPE_8, Winter).In the cruises conducted in 1970 and 1971 two sampling strategies were used. Horizontal trawls of 5 min duration, at 4-5 m depth and at a speed of 3 knots, using Gulf net of 0.18 m of mouth diameter and 500 µm mesh. Vertical trawls with 0.70 m diameter Nansen net and 500 µm mesh, from 50 m depth to the surface, or from the bottom at stations with depths of less than 50 m (Weiss et al. , 1976; Weiss & Souza, 1977). In the cruises made in 1976 the horizontal trawls were obtained at 8 m depth, and only in the first (SUDEPE_5, Summer) were horizontal and vertical trawls conducted. The samples of the cruises 5 and 6 of 1976 (SUDEPE_8) were obtained by the Cruz Del Sur Research Ship through vertical trawls with a conical net of 0.50 m in diameter and 200 µm mesh, from 50 m depth to the surface, or from the bottom at stations with depths less than 50 m (Weiss & Souza, 1977). The volume of filtered water in each trawl was calculated from the measurements obtained from the flowmeter coupled in the nets, and used to standardize the abundance of eggs and fish larvae per 100 m3 of filtered water.

title: (Table 3) Clay mineralogy and calcium carbonate and organic carbon contents of fabric samples of ODP Leg 117

description: Calcium carbonate and organic carbon concentrations are from measurements made on board the JOIDES Resolution during Leg 117 (Prell, Niitsuma, et al., 1989, doi:10.2973/odp.proc.ir.117.1989). Values are for samples immdiately adjacent to fabric samples, or for Site 723 within 25 cm of the fabric sample interval. Intervals for which carbon analyses were not performed are represented by values in parenthesis which are from the nearest interval of similar lithology. Organic carbon analyses were not performed for samples below 402 mbsf at Site 731. Analyses performed on similar sediments at Sites 722 and 731 indicate the organic carbon concentration is probably &lt;0.20%.

title: (Appendix) Inclinations of characteristic directions, polarity and reliability rating for paleomagnetic samples at DSDP Site 89-585

description: Coring in two adjacent holes at DSDP Site 585 (13.5°N, 156.8°E) recovered lower Tertiary through Aptian sedimentary rocks. The paleolatitudes of each hole from the late Aptian through Paleocene were derived from an extensive set of paleomagnetic minicores. Each sample underwent progressive thermal demagnetization, and the characteristic direction of magnetization was derived from the region of stable directions. True mean inclinations were computed for each lithologic unit and for each stage or pair of stages, using the method of Kono (1980b). The results yield average paleolatitudes of 1°S for the Paleocene-Maestrichtian, 7°S for the Santonian-Turonian, and 15°S for the Albian-late Aptian. The Aptian-Albian paleolatitudes agree with paleomagnetic results from DSDP Sites 462 and 289 in the western central Pacific. The average rate of northward drift by the site was about 30 km/m.y. through the Late Cretaceous and earliest Tertiary. The Maestrichtian paleolatitude agrees with a Pacific paleomagnetic pole computed by Gordon (1982) from North Pacific data, but the site is about 12° farther north than predicted by Campanian and Cenomanian North Pacific poles (Gordon, 1983; Gordon and Cox, 1980). Recovery of the latest Cretaceous-early Tertiary sediments was inadequate to allow unique determination of the magnetostratigraphy. No reversed interval could be identified within the late Aptian or early Albian.

description: Mineral and chemical compositions of highly ferruginous layered silicates (HLS) of glauconite sands occurred on the East Korean Rise outside volcanic structures and on an unnamed volcano and the Chentsov Volcano have been studied. The use of cluster and discriminant analyses has resulted to more objectively distinguished groups among HLS, and the use of factor analysis - to illustrate correlations between chemical elements in different groups. It has been found that green mineral assemblages of the East Korean Rise are heterogeneous in terms of morphology, composition and origin, and their formation is a complex multistage process including both neoformation and degradation.

title: (Table 1) Concentrations of phosphorus- and nitrogen forms in the near-bottom layer of the Baltic Sea

description: Nitrogen and phosphorus compounds in the near-bottom layer and interstitial waters in sediments of the Baltic Sea were studied. Statistical analysis of data revealed that variability of hydrochemical conditions in regions of fluid fluxes is higher than in regions without such fluxes. Hydrochemical conditions (concentrations of mineral phosphorus and ammonia in the near-bottom layer) in locations of fluid fluxes appeared to depend on intensity of these fluid fluxes. Influence of the fluid fluxes on formation of the hydrochemical structure and specific conditions is discussed.

description: Between January 3 and February 15, 1979, geoscientific investigations off Northwest Australia (Exmouth Plateau, Cuvier Abyssal Plain, Wallaby Plateau) were carried out on SONNE cruises SO-8A and SO-8B by the Bundesanstalt fur Geowissenschaften (BGR, Hannover) in cooperation with the Bureau of Mineral Resources (BMR, Canberra).The major objective of this cruise was the investigation of the geology and structure of the outer West Australian continental margin between 16° and 26° S. An additional objective of the SO-8 cruise included the sampling of manganese crusts and nodules on the plateaus and the adjacent abyssal plains.From 1983 until 1989 NOAA-NCEI compiled the NOAA-MMS Marine Minerals Geochemical Database from journal articles, technical reports and unpublished sources from other institutions. At the time it was the most extended data compilation on ferromanganese deposits world wide. Initially published in a proprietary format incompatible with present day standards it was jointly decided by AWI and NOAA to transcribe this legacy data into PANGAEA. This transfer is augmented by a careful checking of the original sources when available and the encoding of ancillary information (sample description, method of analysis...) not present in the NOAA-MMS database.

title: (Table 1) Snow and sea ice thickness, solar heat input and solar heat used for melting at seven ice mass-balance buoys in the Arctic in 2008

description: There has been a marked decline in the summer extent of Arctic sea ice over the past few decades. Data from autonomous ice mass-balance buoys can enhance our understanding of this decline. These buoys monitor changes in snow deposition and ablation, ice growth, and ice surface and bottom melt. Results from the summer of 2008 showed considerable large-scale spatial variability in the amount of surface and bottom melt. Small amounts of melting were observed north of Greenland, while melting in the southern Beaufort Sea was quite large. Comparison of net solar heat input to the ice and heat required for surface ablation showed only modest correlation. However, there was a strong correlation between solar heat input to the ocean and bottom melting. As the ice concentration in the Beaufort Sea region decreased, there was an increase in solar heat to the ocean and an increase in bottom melting.
