Abstract
NO 3 − concentration profiles were measured in the sediments of a meso-eutrophic lake with a newly developed microelectrode. The depth of penetration of NO 3 − varied from only 1.3 mm in organic-rich profundal silty sediments to 5 mm in organic-poor littoral sandy sediments. The thickness of the zone of denitrification in the organic-rich sediments was −2 day −1 ) at in situ nitrate concentrations in the overlying water (0.030 mmol liter −1 ) and limitation of denitrification by nitrate availability.Keywords
