The upwelling is an upward displacement of marine waters, although the phenomenon also occurs in lakes and freshwater reservoirs. By the effect of the Coriolis force, originated in the rotation of the Earth, a column of moving water experiences a rotation of 90 ° in relation to the direction of the wind that caused it and that blows along the coast (east effect is called Ekman transport). In this way a wind that blows over the coast can cause a displacement of surface waters towards the offshore, compensated by a slow upward movement of deep waters in the direction of the coast, called upwelling or upwelling of waters. These upwelling waters are of low temperature and extremely rich in nutrients, resulting from the remineralization by bacteria of the organic remains that accumulate in the deeper layers of the water column. By contacting these mineral salts with the photosynthetic organisms that inhabit the surface layer of the sea, an enormous primary productivity results, which translates, through the food chain into a greater fishing biomass.
Landscapes have economic value because the owners of the land or the area have many visitors coming and going and they can put up shops etc to get money
Kuroshio Current is the only option shown in the question above that has no relation to thermohaline circulation and refers to a hot sea current that occurs in conjunction with the cold sea current known as Oyashio. Kuroshio Current is also known as the Japan Current, because its action usually encourages the appearance of shoal on the Japanese fishing coast.
