What happens to fast-moving water as it flows over a bumpy seafloor? Drag, turbulence, eddies and suspended sediment, among other things. Ocean Networks Canada will deploy the “Benthic Boundary Layer” experiment in August in the Strait of Georgia. Our engineers have built this platform to hold an array of instruments to measure water movements and sediment flux near the seafloor. Alex Hay of Dalhousie University designed this configuration to investigate turbulence and the vertical structure of the flow in the bottom boundary layer.
