title: Microbe abundance and biomass in the euphotic zone of the Aegean Sea at Station MARCH-1997-GN36199704601MSB07 in spring 1997

description: 10-30 ml subsamples were concentrated on 25 mm black polycarbonate filters (0.6 µm for NF, 0.2 µm for B), stained with DAPI for 10 min and filtered. NF were counted using UV and blue excitation and enumerated. Heterotrophic B were counted using UV excitation. NF were classified in size categories and biovolume was calculated. NF abundance data were converted into C biomass using 220 fgC µm**-3. Bact abund data were converted into C biomass using 20 fgC cell**-1. BP C was estimated by the 3H-leucine approach according to Kirchman et al. (1986) and Kirchman D.L., 1993. Leucine incorporation as a measure of biomass production by heterotrophic bacteria. In: Kemp P.F. et al. (eds), 1993. Handbook of methods in aquatic microbial ecology. Lewis Publishers, Ann Arbor, 509-512). At each depth duplicate samples and a control one were incubated with 1 nM L-[4,5 3H]-leucine (specific activity 128 Ci/mmol) and 18 nM non-radioactive leucine. Samples were incubated in the dark at in situ temperature.

title: Mesozooplankton average mass during Mikhail Lomonosov cruise ML27, Part III

description: Mesozooplankton was sampled by open-closing JUDAY net with a 36 cm ring diameter and mesh size of 125 µm. Additionally, the JUDAY oceanic model JOM with 300 µm mesh size and 80 cm ring diameter was used. The open-closing mechanism used was the Nansen mechanical lock system allowing nets to be vertically towed through standard depths (0-10, 10-25, 25-50, 50-100, 100-200, 200-300, 300-500 m) and closed at the upper depth level. Depth of tow was evaluated by wire paid out and the angle of wire inclination. The 10-20 ml samples were preserved in 3-4% buffered formaldehyde and processed on return to the laboratory. All of copepods were identified to genus level, other taxanomic groups - to type, class, order and family levels.

title: (Table 3) Trace element abundances at DSDP Hole 72-516F

description: If two pill names are given for a single sample, all elements besides Ir were measured on the pills indicated in the second column. Exceptions occurred for Samples 26, 29, 31, and 35. The indicated errors are the estimated precisions of measurement; i.e., essentially the standard deviations in the counting of gamma rays following activation by neutron irradiation. Because of uncertainties in interference corrections, all precisions are at least 1%, although counting errors for some elements are smaller. The accuracies of the measurements are comparable to the precisions except when flux monitors were used for calibration. Empty cells indicate that the element was not measured in that sample.

title: Nannofossil biohorizons of the late Oligocene section of ODP Hole 120-748B from the Kerguelen Plateau, Southern Ocean (Table 2)

description: Palaeoecological changes in nannofossil assemblages in the Southern Ocean during Oligocene times are examined through high-resolution, quantitative analyses of samples from Ocean Drilling Program (ODP) Site 748 (Kerguelen Plateau). We quantitatively characterized the palaeoecological preference of groups of species and compared their general trends with those determined at Maud Rise (ODP Sites 690 and 689) (Persico, D., Villa, G., 2004. Eocene-Oligocene calcareous nannofossils from Maud Rise and Kerguelen Plateau (Antarctica): palaeoecological and palaeoceanographic implications. Marine Micropaleontology 52, 153-179, doi:10.1016/j.marmicro.2004.05.002). We then attempt a correlation between the main assemblage variation and sea-surface temperature (SST) changes in the Southern Ocean at this time. Relatively stable, cool conditions are interpreted to have persisted from earliest to late Oligocene times, when an increase in abundance of temperate-water taxa is recorded, both at Maud Rise and Kerguelen Plateau, before the Mi-1 event. This reveals a climatic event that probably involved both sites, and which is comparable to that indicated by the global oxygen isotope curve ([Miller, K.G., Wright, J.D., Fairbanks, R.G., 1991. Unlocking the Ice House: Oligocene-Miocene oxygen isotopes, eustasy, and margin erosion. Journal of Geophysical Research, 96, 6829-6848, doi:10.1029/90JB02015; Zachos, J., Pagani, M., Sloan, L., Thomas, E., Billups, K., 2001. Trends, rhythms, and aberrations in global climate 65 Ma to present. Science, 292, 686-693, doi:10.1126/science.1059412.]). In the uppermost Oligocene at Site 689, the temperate-water taxa index ([temperate / temperate+cool]*100) increases from 25.2 Ma. Similarly, at Site 748, the temperate-water taxa index indicates an increase in SST in the late Oligocene, from about 26.5 Ma, at the base of Chron C8n.2n, which is offset by about 1 m.y. between the two areas. The reason for this time difference can probably be found in the location of Site 748 with respect to Site 689, and in the palaeoceanographic setting, taking into account that Site 748 lies north of a deep water passage that separates Kerguelen Plateau from Antarctica, and north of the present day front of the Antarctic Circumpolar Current. The presence of warm-water taxa, exclusively at Site 748, corroborates this hypothesis.

title: (Table T1) Density, porosity, void ratio and silica crystallinity index of ODP Site 185-1149 sediments

description: Siliceous pelagic sediments have been known to be crystallographically altered during burial diagenesis (e.g., Hesse, 1990; Behl and Smith, 1992, doi:10.2973/odp.proc.sr.129.112.1992). In order to know the systematic downhole change of silicification, sediments from Pacific Ocean crust obtained during Ocean Drilling Program Leg 185 Site 1149 (Plank, Ludden, Escutia, et al., 2000, doi:10.2973/odp.proc.ir.185.2000) were analyzed. For collected samples of Early Cretaceous age below the pelagic sediments, which are not as highly silicified, silica mineral crystallization in the siliceous sedimentary rocks is determined by X-ray diffraction (XRD), and the related textural change is shown by using scanning electron microscope (SEM).

title: (Table 1) Interstitial water chemistry at DSDP Leg 81 Holes

description: Interstitial water studies on samples obtained during Leg 81 have revealed substantial changes with depth in dissolved calcium, magnesium, strontium, potassium, and lithium. Calcium and magnesium concentration changes result from alteration reactions, primarily in the basalts and also in the volcanic sediments overlying the basalts. Similarly, depletions in potassium are the result of reactions in volcanic sections of the drill holes. Lithium has its main source in the volcanic sediments. On the other hand, strontium-concentration maxima occur at the ooze-chalk boundary and are the result of carbonate recrystallization reactions. Distinct correlations between calcium gradients and extents of concentration maxima in strontium with sedimentation rates suggest (1) build up of calcium concentrations below diffusion communication depth and (2) increased rates of recrystallization of carbonate with rate of sedimentation. The latter process is probably related to the more "corrosive" character of the sediments as the result of organic carbon diagenesis.

title: Distribution of calcareous nannofossils in the Miocene interval of DSDP Hole 94-608 in the north Atlantic (Fig. 1)

description: DSDP North Atlantic Site 608 yielded an excellent Miocene pelagic section which affords a further opportunity for elucidating the chronology of the calcareous nannofossil succession in the framework of magnetostratigraphic control. Most of the conventional (zonal) markers have been documented for this site and some of the earlier results are confirmed and refined. In addition several unconventional and less known markers have been added. The first two are the highest (last) occurrence of Sphenolithus delphix and Sphenolithus capricornutus at 23.6 Ma, which is immediately above the Oligocene-Miocene boundary as identified by the last occurrence of Reticulofenestra bisecta at 23.7 Ma. The next unconventional datum is the highest (last) occurrence of Ilselithina fusa at 22.8 Ma, which is also the highest (last) occurrence of Helicosphaera recta. Calcidiscus tropicus' lowest (first) occurrence is at 19.5 Ma, which is also the lowest occurrence of Sphenolithus belemnos, and Calcidiscus leptoporus' lowest (first) occurrence coincides with that of Sphenolithus heteromorphus at 18.5 Ma. Sphenolithus dissimilis' highest (last) occurrence is at 18.2 Ma and the Calcidiscus premacintyrei lowest (first) and highest (last) occurrences are, respectively, at 17.7 and 11.7 Ma. Discoaster braarudii occurs from 11.6 to 11.3 Ma and its highest (last) occurrence corresponds to that of Cyclicargolithus floridanus. Minylitha convallis occurs from 9.0 to 6.9 Ma. Within the range of Minylitha, at 8.0 Ma, a major shift occurs in reticulofenestrid placoliths from dominantly large (Reticulofenestra pseudoumbilicus) and medium size (Reticulofenestra minutula) species below to significant numbers of very small species (Dictyococcites productus and Gephyrocapsa) above. This is interpreted to be a major, though perhaps seasonal, change of productivity of the North Atlantic at Site 608.A new genus and species Cryptococcolithus takayamae, is described and a variety, Reticulofenestra pseudoumbilicus var. amplus is identified.

title: Mesozooplankton average length during Akademik Kovalevsky cruise AK7/4, Part II

description: Mesozooplankton was sampled by open-closing JUDAY net with a 36 cm ring diameter and mesh size of 0.145 mm. The open-closing mechanism used was the Nansen mechanical lock system allowing nets to be vertically towed through standard depths (0-10, 10-25, 25-50, 50-100, 100-200, 200-500 m) and closed at the upper depth level. Depth of tow was evaluated by wire paid out and the angle of wire inclination. The 10-20 ml samples were preserved in 3-4% buffered formaldehyde and processed on return to the laboratory. All of copepods were identified to genus level, other taxanomic groups - to type, class, order and family levels.
