MD02-2489 (MD022489) * Latitude: 54.390700 * Longitude: -148.921300 * Date/Time: 2002-05-23T00:00:00 * Elevation: -3640.0 m * Recovery: 29.8 m * Campaign: MD122 (IMAGES VII - WEPAMA) * Basis: Marion Dufresne * Method/Device: Giant piston corer (GPC) * Comment: Originally the site and core belonged to the cruise IMAGES VII WEPAMA but was postponed due to tight schedule. The core was then taken in 2002, during transit, preliminary to cruise IMAGES VIII MONA.
Chlorin concentrations were calculated from CPE (chloroplastic pigment equivalents) values measured with a Turner-Flourometer TD-700, applying standard procedures of IFM-GEOMAR, Kiel. Pigments were released with acetone and a cell-mill from 100 mg of freeze-dried and crushed sediment and acidified with HCl to change chlorophyll-a into phaeopigments. A Sigma-Aldrich 25730-chlorophyll-a solution was used to produce a standard for CPE-measurements. Chlorin concentrations are given in ng/g.
