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...

The magnetic susceptibility is measured by an inductive AC device (BARTINGTON). The sample is placed inside a coil which generates an alternating magnetic field. The applied...

In the KTB field laboratory, porosity, internal surface and permeability were determined on identical mini cores with 25.4 mm in diameter and approximately 50 mm in length....

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...

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...

Cuttings were crushed in a tungsten carbide ball mill for 25 min; while core samples were crushed in a tungsten carbide jaw breaker and then processed in the same way as the...

The density of rocks depends on the mineral contents and is therefore a helpful property for the discrimination of lithological units. It is also used for the calculation of...

In general, four-electrode devices are used to measure the resistivity on original (unprepared) cores and on mini cores drilled from these original cores. The in-phase and the...

Ultrasonic wave propagation through core samples is studied in a water tank to insure good signal transmission between transducer, rock specimen and receiver and to avoid time -...

In the KTB field laboratory, porosity, internal surface and permeability were determined on identical mini cores with 25.4 mm in diameter and approximately 50 mm in length....

The main objective of this drilling fluid analysis was the detection of inflows of formation fluids. Therefore different gases dissolved in the drilling mud were measured...

SAFOD is motivated by the need to answer fundamental questions about the physical and chemical processes controlling faulting and earthquake generation within a major...

Geochemical Analysis of Cations of Mud Samples of the KTB Main Hole HB1.

In the laboratory, the gamma radiation is measured by a sodium iodtite (NaI) scintillation detector (cores and cuttings) and by a germanium (Ge) semiconductor detector...

The qualitative and quantitative phase analyses were performed in the KTB field laboratory by x-ray powder diffraction using SIEMENS D 500 diffractometer. During early stages of...

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...
