Upwelling Bays: How Coastal Upwelling Controls Circulation, Habitat, and Productivity in Bays

Annual Review of Marine Science, 2020
Bays in coastal upwelling regions are physically driven and biochemically fueled by their interaction with open coastal waters. Wind-driven flow over the shelf imposes a circulation in the bay, which is also influenced by local wind stress and thermal bay–ocean density differences.

Upwelling age: an indicator of local tendency for coastal upwelling

Journal of Oceanography, 2011
A proxy named “upwelling age”, defined as the ratio of wind time scale to “advection time”, was developed to quantify the local tendency for coastal upwelling. The formulation of the “advection time” was derived from Ekman theory. A 3D numerical model was used to validate and refine the theoretical formula by simulating a total of 30 cases of different

A documentary proxy for coastal upwelling

2023
Coastal upwelling is a process in which sea water from intermediate depths emerges along the west coast of continents in response to the intensity of the alongshore component of the wind. These areas are economically relevant as upwelled water is rich in nutrients, creating regions of great interest for fisheries.Quantifying upwelling intensity at ...

The Peruvian Coastal Upwelling System

2001
The Peruvian coastal upwelling ecosystem is part of an upwelling area that extends between 4°S and about 40°S along the western coast of South America (Guillen 1983), with high productivity originating from equatorial upwelling south of the Galapagos Islands.

Chapter 6 Coastal Upwelling Dynamics

1989
Publisher Summary This chapter describes the results of two experiments that are explicitly designed to elucidate the physical control of mesoscale biomass and nutrient patterns in a region where upwelling processes may be quasi-two-dimensional. Although the study region (the mid-Washington shelf) exhibits significant alongshore gradients in physical

A Cyclesonde View of Coastal Upwelling

Journal of Physical Oceanography, 1976
Abstract In August 1973, 320 vertical profiles of temperature and horizontal velocity were recorded during a 64 h period by an array of three Cyclesondes in the coastal upwelling region off Oregon. The mean interior along-shore velocity was geostrophic and a linear function of density, with a near-surface, equatorward jet at mid-shelf, and a poleward ...

Coastal Effects on Upwelling.

1983
Steady wind parallel to the coast generates upwelling and the influence of the spatial structure of the wind or the coastal indentattions must be taken into account in the determination of the lifting of the thermocline. A shallow water model is used to display the response of the ocean around a cape. The response to steady wind forcing is described in
