stream-like movements of water that occur at or near the surface of the ocean Can reach depths of several hundred meters Can reach depths of several hundred meters Example: Gyres Example: Gyres
In subject area: Earth and Planetary Sciences Barotropic flow is defined as a type of flow in ocean dynamics where the density is solely dependent on pressure, resulting in a nearly constant density with minor variations in pressure and temperature. AI generated definition based on: Nonlinear Ocea...
Ocean gyreIn this paper, existence and uniqueness of solutions for the nonlinear and linear models of the arctic gyres over 84 north latitude are studied by using the stereographic projection, which represents the streamline and no jet at the outside boundary. By using the fixed point technique,...
A plausible explanation is that this net flux is pumped downward by the convergent wind-driven Ekman pumping, as is typical of all midlatitude anticlyclonic gyres. The downward flux can follow isopycnals to depths (500–600 m) and deeper by eddy mixing; a mechanism for forcing deep water ...
Six velocity sections straddling Cape Hatteras show a deep counterflow rounding the Cape wedged beneath the poleward flowing Gulf Stream and the continental slope. This counterflow is likely the upper part of the equatorward-flowing Deep Western Boundary
In subject area: Earth and Planetary Sciences Geostrophic flow, and hence the topography of the thermocline, is rendered the more complex by the change of sign of the Coriolis force at the equator, which the province straddles. From: Ecological Geography of the Sea (Second Edition), 2007 About...
The northernmost extension of the Atlantic-wide overturning circulation consists of the flow of Atlantic Water through the Arctic Ocean. Two passages form the gateways for warm and saline Atlantic Water to the Arctic: the shallow Barents Sea and the Fram Strait which is the only deep connection ...
Ocean gyreIn this paper, existence and uniqueness of solutions for the nonlinear and linear models of the arctic gyres over 84 degrees north latitude are studied by using the stereographic projection, which represents the streamline and no jet at the outside boundary. By using the fixed point ...
To the right of the detached upstream current is a closed gyre that connects the upstream flows (that have different patterns depending on source location) with the unique passage flows. The results suggest that gyres upstream of critically controlling passages in the ocean might serve as ...
