POS55_S57b (S57.2) * Latitude: 57.798300 * Longitude: 9.131700 * Date/Time: 1980-03-08T00:00:00 * Elevation: 129.0 m * Campaign: POS55 * Basis: Poseidon * Method/Device: Gravity corer (GC) * Comment: Gravity corer (Rumohr type, 1 m, diam. 80 mm); core stored upright, desiccated at core base, supernate water loss 2.3 cm, shrinkage 0.9 cm [1980.04.08-1982-02-25]; core length 0.069 m, sampled on 1982-02-25 as 1 cm wide slices at every 1 cm (possibly different at top or base), split for a) W/Pb210/Cs137 with drying at 70°C, and b) grain size/metal studies.
Comment:
Water: weight loss by drying
Pb210: conc. HNO3/HCl digestion, Po210 deposition , Po210 alpha counting, surf. barrier detector (Erlenkeuser and Pederstad, 1984)
Pb(Po)210 age: CIC model. CIC Model Parameters: 61 [Bq/kg] Initial Conc.; 4.5 [Bq/kg] Supported Conc.; 0.05 [Bq/kg] Std e of Supported Conc.;1980 Start Year [a AD]; Halflife: 22.3 a (Erlenkeuser, 1985)
CS137: dry sed., gamma counting, low level HPGe-detector (Huebener et al, 2009)
