Corelogger Protocol

Core label: PS64/330 Core type: SL

Length: 1.54m

1. Measurement

Date: 02.07.2003 Name: Usbeck

Section Corelabel Comments

1 0-53.5 Bad acoustic coupling (gas) 2 153.5 – 154 Air / gas from 73-103 cm Total 154

Comments:

• Measured at approx. 6°C, directly after retrieval

• Poor acoustic signal due to high gas content

• Temperatures logged (approx. every 10 cm)

• T from ca. 6 °C (top) to -1°C (bottom)

• PW-velocities probably not correct (gas caves in core, low amplitudes)

2. Processing

Name: Usbeck

MSCL-parameter, measurement conditions, and calibrations:

• PTO: 7.49 µs at 7.7°C

• γ-Density: a = 0.0002, b = -0.0703, c = 9.9317

• PW-velocity normalized to 20°C

• BED = 0.0

• Liner thickness 2.5 mm

• Outer liner diameter 125 mm

• Susceptibility sensor (10-6 SI): Loop

• Susceptibility volume correction (10-5 SI): 6.39 Comments:

• Drift and ends of cores corrected for magnetic susceptibility (10cm).

• Negative susceptibility values removed

• Density values and at section breaks removed

• Temperature and PW-veloc. supplied to PANGAEA
