dc.description.abstractOcean studies in the 1970s provided an improved knowledge of the coastal upwelling region off NW Africa while in the 1980s and 1990s they led to a good description of the open ocean flow patterns in the Canary Basin. It was not until the late 1990s that major research addressed the open-coastal ocean coupled response. Here we examine the mean and seasonal circulation patterns in the Canary Basin with data from four hydrographic cruises carried out in the region between Cape Ghir, Madeira Island, and the Canary Islands. We apply an inverse box model to an ocean divided into 14 layers, with several layers representing each water mass or stratum, to obtain mass fluxes consistent with the thermal wind equation. An optimum flow description is obtained using conservation of mass, salt and heat anomaly, biologically corrected oxygen, and silicate, and allowing for Ekman transport in the surface layer and dianeutral mixing between adjacent layers. The deep waters show no predominant flow direction while the intermediate waters display localized southward flowing Mediterranean Water far from shore, and northward flowing Antarctic Intermediate Water near the continental slope, specially in the passage between the eastern Canary Islands and the African slope. The mean upper-thermocline Canary Current, composed of North Atlantic Central Water, flows south with an open-ocean branch transporting about 3 +/- 1 Sv (1 Sv = 10(6) m(3) s(-1) congruent to 10(9) kg s(-1)), and an upwelling-related branch near the continental slope carrying 1 +/- 0.3 Sv. The seasonal transport by the open-ocean branch intensifies and moves offshore from spring to fall (2.8 +/- 1.2 Sv in spring, 2.9 +/- 1.1 Sv in summer, and 4.5 +/- 1.2 Sv in fall), while it carries its lowest southward mass flux in winter (1.7 +/- 1.0 Sv), possibly as a result of a migration offshore the sampled region. Upwelling-related southward flow is present in spring and summer (1.9 +/- 0.1 Sv and 2.4 +/- 0.1 Sv, respectively) while in fall and winter it merges with the offshore southward branch. This westward migration allows a northward mass flux between the Canary Islands and the African coast (1.8 +/- 0.1 Sv), that by winter reaches Cape Ghir (0.5 +/- 0.2 Sv). Seasonal air-sea heat fluxes fit well with the climatological values. The net phosphate transport in the surface layer indicates that primary production was negligible in this region during January 1997 and April 1998, though in this last month production was probably starting as a result of significant nutrient supply.
