title: (Table 1) Wet and dry density and porosity of mudstone at DSDP 84 holes

description: Vein structure and related small fractures in muddy sedimentary Oligocene to Miocene rocks of Sites 568 and 569 have been analyzed to study the deformation and tectonics of the Middle America Trench landward slope area off Guatemala. These veins are filled with fine, clayey materials and essentially developed as extensional fracture cleavages perpendicular to the minimum principal compressive stress axis. Three stages are recognized; early stage fractures parallel to bedding (probably caused by bedding parallel slip), abundant fractures highly oblique or perpendicular to bedding, and veins formed at various angles during tilting. Most of the veins show drag or rotation features, which mostly show downdip sliding and probably occurred during stages of large-scale folding related to faulting or draping of the middle Trench slope area. Veins are concentrated only in the middle part of the Trench landward slope of the late Oligocene to middle Miocene sections, where high sedimentation rates and possible normal faulting and folding caused by local uplift of the basement occurred. This may indicate that the veins required rapid sediment consolidation, which caused abnormal lithification

title: Table 3: Comparison of freshwater species in Ob and Yenisei during the 1997 cruise

description: Phytoplankton biomass distribution (chlorophyll a, chl. a) and species composition (cell numbers) were investigated during three expeditions to the Kara Sea with "Akademik Boris Petrov" (BP) in 1997, 1999, and 2000. The distribution of biomass in the estuaries of Ob and Yenisei showed a similar range in 1997 (0.2 to 3.2 µg/l) and 2000 (0.4 to 3.5 ug/l); higher chl. a concentrations during these two years were found in Yenisei than in Ob. In 1999, phytoplankton biomass in the Ob and Ob Estuary was much higher than in 1997 and 2000, with maximum values above 10.0 ug chl. a/l. In 1999, biomass in Yenisei was lower (1.5 to ~5 ug/l) than in Ob but slightly higher than in 1997 and in 2000. During the expedition in 2000, the research area extended farther to the north, here, lowest phytoplankton biomass during all three years was found. Typical summer values for integrated chl.a biomass (surface to bottom) ranged between 6 and 20 mg m**-2. Strong differences existed in species composition in both rivers, the estuaries, and the open Kara Sea. In general, three or four different populations could be distinguished in surface waters: (1) freshwater diatoms together with bluegreen algae in both rivers, (2) centric and small pennate diatoms mainly brackish species in the estuaries, (3) north of 74°N, brackish/marine species dominated, i.e. in 1999 Thalassiosira cfpunctigera and Chaetoceros spp prevailed in the phytoplankton bloom in Ob. (4) At the northernmost, almost marine stations, a region with a more heterogeneous composition of unicellular plankton was encountered. We assume, we found different seasonal signals of phytoplankton development during 1997/2000 and 1999, respectively. However, the yearly fluctuation of freshwater runoff of both rivers seems to have the strongest influence on the timing and duration of phytoplankton blooms, species compositions and biomass standing stocks during summer.

title: Size exclusion chromatogram of the Tannermoor 2009 sample after saltout experiments

description: Samples from a pristine raised peat bog runoff in Austria, the Tannermoor creek, were analysed for their iron linked to natural organic matter (NOM) content. Dissolved organic carbon &lt; 0.45 µm (DOC) was 41 to 64 mg/L, iron 4.4 to 5.5 mg/L. Samples were analysed applying asymmetric field flow fractionation (AsFlFFF) coupled to UV-Vis absorption, fluorescence and inductively coupled plasma mass spectrometry (ICP-MS). The samples showed an iron peak associated with the NOM peak, one sample exhibiting a second peak of iron independent from the NOM peak. As highland peat bogs with similar climatic conditions and vegetation to the Tanner Moor are found throughout the world, including areas adjacent to the sea, we examined the behaviour of NOM and iron in samples brought to euhaline (35 per mil) conditions with artificial sea salt. The enhanced ionic strength reduced NOM by 53% and iron by 82%. Size exclusion chromatography (SEC) of the samples at sea-like salinity revealed two major fractions of NOM associated with different iron concentrations. The larger one, eluting sharply after the upper exclusion limits of 4000-5000 g/mol, seems to be most important for iron chelating. The results outline the global importance of sub-mountainous and mountainous raised peat bogs as a source of iron chelators to the marine environment at sites where such peat bogs release their run-offs into the sea.

title: (Table 1) Strontium concentration and isotope ratios of carbonates from DSDP Holes 69-504B as well as 83-504B and fish debris samples from Indian and Pacific Ocean sediments

description: Recent revisions of the geological time scale by Kent and Gradstein (in press) suggest that, on the average, Cretaceous magnetic anomalies are approximately 10 m.y. older than in Larson and Hilde's (1975) previous time scale. These revised basement ages change estimates for the duration of alteration in the ocean crust, based on the difference between secondary-mineral isochron ages and magnetic isochron-crustal ages, from 3 to approximately 13 m.y.In addition to the revised time scale, Burke et al.'s (1982) new data on the temporal variation of 87Sr/86Sr in seawater allow a better understanding of the timing of alteration and more realistic determinations of water/rock ratios during seawater-basalt interaction. Carbonates from all DSDP sites which reached Layer 2 of Atlantic crust (Sites 105, 332, 417, and 418) are deposited within 10-15 m.y. of crustal formation from solutions with 87Sr/86Sr ratios identical to unaltered or contemporaneous seawater. Comparisons of the revised seawater curve with the 87Sr/86Sr of basement carbonates is consistent with a duration of approximately 10-15 m.y. for alteration in the ocean crust.Our preliminary Sr and 87Sr/86Sr data for carbonates from Hole 504B, on 5.9-m.y.-old crust south of the Costa Rica Rift, suggest that hydrous solutions from which carbonates precipitated contained substantial amounts of basaltic Sr. For this reason, carbonate 87Sr/86Sr cannot be used to estimate the duration of alteration at this site. A basalt-dominated alteration environment at Hole 504B is consistent with heat-flow evidence which indicates rapid sediment burial of crust at the Costa Rica Rift, sealing it from access by seawater and resulting in unusually low water/rock ratios during alteration.

description: Basal part of the Laacher See tephra (LST) layer (upper third of the image) in the sediment record of Sacrower See, NE Germany. The tephra layer has been dated to 12,880 varve years BP in sediments of Meerfelder Maar, Eifel, Germany (Brauer et al., 1999).The tephra layer mainly consists of volcanic glas with gas vesicules. The condenser aperture of the microscope has been closed to increase the contrast between the glas particles and the embedding resin which have a similar refractive index.

description: The Japan Sea experienced bottom water anoxia at the last glacial maximum (LGM) since it is surrounded by four shallow straits, the sill depths of which are close to, or shallower than, the drop in sea level (~120 m) that occurred then. A distinctive negative d18O excursion of planktonic foraminifera also took place during the LGM. This excursion has been interpreted from foraminiferal data as recording a drop in the paleosalinity of surface waters on the assumption of a constant low sea surface temperatures between 34 and 11 ka. We present here a profile of alkenone-based sea surface temperatures (alkenone-SSTs) over the past 36 kyr. Our results suggest that SSTs during the LGM were much higher than those previously assumed. After considering the factors that might affect estimation of alkenone-SSTs and comparisons of core-top alkenone-SSTs values with values for modern seawater we conclude that the higher alkenone-SSTs during the LGM are reliable and reasonable. These warm SSTs were probably caused by radiative equilibrium associated with the development of stable water stratification in the Japan Sea during the LGM.

description: The deformation of a 20 m deep firn pit in the accumulation area of Kesselwandferner was surveyed over aperiod of 11 years. Six or seven surveying markers had been installed at each of 14 levels. The survey shows tImt the shear strain rate is independent of depth and the originally circular pit cross section was changed into an ellipse. In the direction of the glacier flow, the diameter was increased, the strain rate being approximately independent of depth. Transverse to the flow, however, the diameter decreased, the strain rate becoming higher as the depth increased. The vertical strain rates responsible for thinning of firn layers decrease with depth.

title: (Table 7) Hiatuses and compressed intervals at DSDP Leg 85 sediments

description: Biostratigraphic studies using planktonic and benthic foraminifers, calcareous nannofossils, radiolarians, diatoms, and silicoflagellates are summarized for the four main sequences (Sites 572 to 575) collected during DSDP Leg 85 in the central equatorial Pacific. Upper Eocene through Quaternary reference sections were recovered at Sites 573 and 574, and middle Miocene through Quaternary and lower Miocene through Quaternary reference sections were cored at Sites 572 and 575, respectively. Detailed graphic correlation plots suggest that Site 573 may contain as many as nine short hiatuses. Site 572 in the fertile eastern equatorial Pacific is apparently free of hiatuses, and Sites 574 and 575 have hiatuses (two each) only in the compressed upper sections. Few inconsistencies exist in the various microfossil stratigraphies. Diachronous species occurrences are identified, and age estimates for 66 late Eocene through Quaternary microfossil datums have been extrapolated from age-vs.-depth plots constructed from 63 datums with direct and/or indirect ties to paleomagnetic stratigraphy. An addendum presents an alternative biostratigraphic time scale for the middle and late Miocene based on a correlation of paleomagnetic Anomaly 5 with paleomagnetic Chron 11.

title: (Table 1) Oxygen and carbon isotopic values for mixed species of Cibicidoides at DSDP Hole 85-574

description: Oxygen and carbon isotopic data from mixed species of the benthic foraminifer Cibicidoides at Site 574 in the equatorial Pacific are compared with benthic foraminiferal isotopic data from equatorial Pacific Site 77 (Keigwin and Keller, 1984) and western North Atlantic Site 563 (Miller and Fairbanks, 1983, in press). Cibicidoides within the age range of about 33 to 35 Ma (within the early Oligocene) at the Pacific sites were lower in d13C than those of the same age from the North Atlantic site. For those from about 26 to 33 Ma (late early to late Oligocene), the equatorial Pacific and western North Atlantic d13C values were similar, whereas for those from about 26 to 12 Ma (latest Oligocene to Miocene) (see Miller and Fairbanks, 1983), Pacific values were lower. We suggest that this reflects bottom-water production analogous to modern North Atlantic Deep Water (NADW) in the early Oligocene and latest Oligocene to Miocene and reduced production of "NADW" in the late early to late Oligocene. High d18O values (approximately 2.0 per mil) were recorded at Site 574 for Cibicidoides at 36 Ma (earliest Oligocene); high, oscillating d18O values occurred from 30 to 29 Ma (near the early/late Oligocene boundary). These intervals of high d18O values apparently represent either bottom waters colder than at present or the presence of significant continental ice sheets. We suggest that major periods of continental glaciation occurred at approximately 36 and from 29 to 30 Ma.
