This front seems to be related to the cold water
upwelled off Punta Lavapie, which is then transported northward by a coastal jet that flows along the shelf break (Fig.
The upwelling filaments defined two frontal zones, a coastal front and an oceanic front both associated with
upwelled cold-waters (Fig.
Ohwaki, "Numerical experiments of upwelling in Tokyo Bay in relation to "Aoshio" (the
upwelled anoxic blue-green turbid water)," Bulletin on Coastal Oceanography, vol.
This
upwelled water is relatively rich in iron, the macronutrient needed for growth by most organisms, and the production is high in many areas of the Galapagos and surrounding waters [7].
2) it is assumed that the
upwelled water was originated at this depth-range during our experiment.
The high productivity of the California Current (CC) is primarily the result of local wind-driven seasonal upwelling and the interaction of alongshore currents with prominent coastal features such as capes, headlands, and bays that advect
upwelled water masses into complex patterns of offshore filaments and coastal retentive eddies (Davis, 1985; Gan and Allen, 2002).
This implies that either water which
upwelled in the Southern Ocean, after 16,500 years ago, had a vigorous exchange with the atmosphere, allowing its 14C-clock to be reset, or the circulation was significantly different than what the current paradigm is.
The
upwelled water did not reach the sea surface at the site of the mooring station.
The Peruvian and Chilean regions differ in their upwelling characteristics as well, with stronger winds along the Peruvian coast upwelling subsurface countercurrent water, while off Chile subantarctic water of the equatorward flowing coastal current is
upwelled (Wolff et al., 2003).
Therefore, statistical analyses of upwelling parameters (horizontal scales of the
upwelled water and the upwelling-related filaments, temperature differences between the
upwelled and the surrounding water) as well as the frequency of upwelling events during summer by using SST from satellite remote sensing images is an important task.
