AbstractDuring summer, when oligotrophic conditions prevail offshore in the Mediterranean Seea, an alongshore zone with enhanced phytoplankton biomass is ofteen evidenced in these waters. Here, using high continuous measurements of temperature, salinity and fluorrescence as well as discrete samples and primary production experiments, we examine the cross-shore typology and the associated chemical and biological characteristics of these waters. Data from three coastal regions in the NW Mediterranean revealed widespread presence of lower water density bands in the proximity of the shoreline generated by increased warming and groundwater seeps through the coastal sediments. Most often, enhanced phytoplankton biomass (max=9.6 mg Chla m3; up to 16 fold offshore chlorophyll) was associated with these modified waters and exponentially decayed in the offshore direction. Gradient characteristics are highly variable but the main onshore-offshore features, determined by terrestrial loads and hydrodynamics are locally consistent. Important variations were observed in the structure of the communities among nearshore sites which were attributed to variations in the geochemical conditions. Our study argues the relevance of the formation of a groundwater-sustained nearshore niche and its temporal stability for the development of a distinct community which could eventually favor the emergence of harmful algal blooms
