Boundary layer flow dynamics at a cold-water coral reef

The Tisler cold-water coral reef is a 2 km long reef in the north-eastern Skagerrak, Norway. The reef is comprised principally of Lophelia pertusa at depths between 70 and 160 m. Velocity shear and boundary layer shear stresses have been measured at Tisler Reef to quantify the effect of the reef structure on the benthic boundary layer (BBL) dynamics. Two different approaches to estimating the magnitude of the near seabed stress were employed:...
