Wind-Forced Seasonal Exchange Between Marginal Seas and the Open Ocean

Explore the dynamics of wind-driven circulation in marginal seas and their exchange with the open ocean through this 44-minute lecture. Delve into idealized numerical models and theories examining the strong seasonal wind cycles over the Nordic Seas and their interaction with the subpolar North Atlantic Ocean. Identify two distinct regimes: an interior with closed f/h contours and a shallow shelf region connecting to the open ocean. Analyze the development of strong oscillating along-topography circulation in the interior and the factors influencing bottom Ekman layer and interior ageostrophic flows. Investigate shelf dynamics controlled by frictional decay of coastal waves and their impact on surface Ekman transport and exchange with the open ocean. Discover the direct connection between coastal wave dynamics on the shelf and deep water exchange through straits. Gain insights into the complex interplay between wind forcing, topography, and ocean circulation in marginal seas, with implications for understanding planetary-scale fluid flows.
