Abstract

Abstract Shallow benthic habitats are hotspots for carbon cycling and energy flow, but metabolism (primary production and respiration) dynamics and habitat-specific differences remain poorly understood. We investigated daily, seasonal, and annual metabolism in six key benthic habitats in the Baltic Sea using ~?2900?h of in situ aquatic eddy covariance oxygen flux measurements. Rocky substrates had the highest metabolism rates. Habitat-specific annual primary production per m2 was in the order Fucus vesiculosus canopy?>?Mytilus trossulus reef?>?Zostera marina canopy?>?mixed macrophytes canopy?>?sands, whereas respiration was in the order M. trossulus?>?F. vesiculosus?>?Z. marina?>?mixed macrophytes?> sands?>?aphotic sediments. Winter metabolism contributed 22?31% of annual rates. Spatial upscaling revealed that benthic habitats drive >?90% of ecosystem metabolism in waters ≤5?m depth, highlighting their central role in carbon and nutrient cycling in shallow waters.
