Boundaries
Source waters for the Benguela include Indian and South Atlantic subtropical thermocline water; saline, low-oxygen tropical Atlantic water; and cooler, fresher deep water. The Benguela current is 200 to 300 km wide and widens further as it flows north and northwest. Its western, seaward edge is ill-defined, with many temporary and seasonal eddies and meanders. There is however a well-defined thermal front between the waters associated with the Benguela Upwelling System and those of the south east Atlantic.
Where the icy Benguela and the warm, south-flowing Agulhas current mix, there is a richly productive marine ecosystem off the Cape of Good Hope but storms and turbulence above.

Famous quotes containing the word boundaries:
“The boundaries which divide Life from Death are at best shadowy and vague. Who shall say where the one ends, and where the other begins?”
—Edgar Allan Poe (1809–1845)
“Ideas are not thoughts; the thought respects the boundaries that the idea ignores thereby failing to realize itself.”
—Franz Grillparzer (1791–1872)
“Women’s art, though created in solitude, wells up out of community. There is, clearly, both enormous hunger for the work thus being diffused, and an explosion of creative energy, bursting through the coercive choicelessness of the system on whose boundaries we are working.”
—Adrienne Rich (b. 1929)
