Organic carbon and nitrogen in marine sediment from short time moorings during TYDEMAN cruise DCM

Marine sediments for determination of organic carbon and nitrogen was collected using paired funnel-shaped traps (0.0314 m**2 opening) suspending on buoys at two depths. One set of traps was deployed at 300 m, the other ones just below the chlorophyll maximum. After 24 hours traps were recovered and the marine sediment filtered on pre-combusted GF/C filters and stored at -20°C. Organic carbon was determined after removing carbonate carbon by acidification with sulfurous acid.
