DESCRIPTION:
SONNE cores 17940-1 and 17940-2 (Core 17940-1 is a giant-spade box core 
and core 17940-2 is a gravity core)
2007'N, 11723'E; 1727 m water depth; 13.30 m long

AMS 14C:
AMS14C are measured on all Globigerinoides ruber.

d18O:
d18O isotope measurement, in permil. , ±0.08 ‰ PDB			
Oxygen isotopes are measured on 15-20 specimens of Globigerinoides ruber (white) s.s.
Chronostratigraphy: smooth spline fit of 40 AMS dates and direct correlation with 
GISP2 ice core d18O
Standard  method of Ganssen, G. and M. Sarnthein, [1983]

Clay Content:
clay content, %, 0.27±0.47, in the sediment siliciclastic  fraction <63 micron.
clay contents were measured on a SediGraph 5100D made by Micromeritics 
according to procedures described by Stein [1985]

Median Grain Size:
Silt median grain size (micron) in the sediment siliciclastic  fraction <63 micron

Modal Grain Size:
Grain size were measured on a SediGraph 5100D made by Micromeritics, 
according to procedures described by Stein [1985]:
