Porewater oxygen profiles in surface sediments of the North Atlantic Basin during RV Maria S. Merian cruise MSM96 ...
Vertical profiles of dissolved oxygen (O2) concentrations in the surface sediment of the North Atlantic Basin were acquired during MSM96 through ex-situ voltametric measurements during this research cruise. For every multicorer station, one liner was selected and transported to the on-board cool roo...
