Abstract:
Pore water nitrate concentrations were measured on board with a SEAL QuAAtro continuous flow auto analyzer. Pore water samples for dissolved element analysis were acidified with HCl to pH < 2 after sampling. Depending on the concentration range, pore water K and Fe was measured by inductively coupled plasma optical emission spectrometry (Varian 720 ES) or inductively coupled plasma mass spectrometry (Agilent 7500).
