Laboratory processing of concentrates was aimed at the removal of non-sporomorph organic matter by means of chemical treatment, micro-sieving and heavy liquid seperation. The...

High temperature measurements of magnetic susceptibility in clay-rich layers. Magnetite, characterised by a Curie temperature of 590 °C, dominates the signal.

The vertical distribution of organisms in the sediment indicates that animals can be present as deep as 15 cm although at very low abundance at such depths (Fig. 4, Fig. 5 and...

Sediment slices of 0.5 cm thickness were obtained from gravity core segments and of 1 cm thickness from the Vydrino piston core. Volumetric subsamples of 5 cm3 (10 cm3 in case...

High temperature measurements of magnetic susceptibility in diatomaceous layers. Most of the weak susceptibility is still present up to the temperature of 670 °C and carried by...

The day plot (Fig. 6B; Day et al., 1977) indicates that samples with S-ratios >0.95 plot rather in the single-domain (SD) to pseudosingle-domain (PSD) range. Samples with...

Porewater samples were conserved with 0.2% chloroform and analyzed at EAWAG, Switzerland, for NO3-, NH4+, SiO2, and o-PO4 using standard photometric methods (DEW, 1996). In...

The vertical distribution of organisms in the sediment indicates that animals can be present as deep as 15 cm although at very low abundance at such depths (Fig. 4, Fig. 5 and...

S. grandis is by far the species that contributes the most to the total biovolume accumulation rate with a peak value just above 4×106 μm3 cm−2 year−1. Its relative contribution...

Higher abundance of greigite during glacial intervals also coincides with small increases of the S content (Fig. 11B). Greigite levels in glacial sediments cannot be correlated...

Values of measured chlorophyll (HPLC=High Pressure Liquid Chromatography) are the mean concentrations of each sampling point from 5 to 30 m depth. For the OC2 chl-a...

Wet bulk density (GRAPE) of pilot core CONT01-604-3a to piston core CON01-604-3 at Posolskoe

Wet bulk density (GRAPE) of trigger core CON01-605-4a to piston core CON01-605-4a at Vydrino

Anhysteretic remanent magnetisation (ARM) measurements, free of the effect of the dia-, para- and superparamagnetic components, provide an estimation of the magnetic remanence...

It shows a loss of a part of the signal at temperatures between 350 and 400 °C, typical disintegration temperatures for greigite. The remaining signal disappears above a...

Sediment slices of 0.5 cm thickness were obtained from gravity core segments and of 1 cm thickness from the Vydrino piston core. Volumetric subsamples of 5 cm3 (10 cm3 in case...

Dashed lines mark some correlation levels of the cores from Lake Baikal with the dated δ18O record from ODP 677 (Shackleton et al., 1990), see also Fig. 3. Diagenetic features...

It shows a loss of a part of the signal at temperatures between 350 and 400 °C, typical disintegration temperatures for greigite. The remaining signal disappears above a...

No significant HIRM change is observed at the transition between oxidising and reducing conditions in the sediment (Fig. 9A). This implies that HIRM is not affected by redox...

Selected intervals of down-core variations of normalised relative paleointensity, ChRM inclination and declination, and the reversal angle. (A) Core CON 01-603-2: numbers in the...
