Abstract
We present high‐resolution vertical profiles of methylated mercury (MeHgT = monomethylmercury + dimethylmercury) concentrations in the water column of the open and marginal areas of the Mediterranean Sea. MeHgT concentrations ranged from −1 to 0.430 pmol L −1 (n = 130), with maximal concentrations occurring within the maxima of oxygen consumption. Within the most biologically active zone (0‐600 m), the MeHgT vertical profiles exhibited a nutrient‐like pattern. The MeHgT vs. phosphate relationships were highly significant (p
