Short summary
Internal waves along the Bay of Biscay coast transport water distinctly: surface and seafloor water moves shoreward while mid-depth water moves offshore, matching linear internal tide theory. This transport equals effects of moderate winds that typically dominate. Internal waves were the main transport at one site and enhanced shoreward flow near the seabed at another. Understanding these patterns could explain movement of nutrients, sediments, and pollutants affecting coastal ecosystems.
