Hydrologie du Maroc atlantique

Many oceanographers acknowledge the particular features of the waters from the continental shelf-also called continental waters, but which should be called coastal waters. Less saline than offshore waters, coastal waters are often warmer in the summer and colder in the winter, at least in temperate regions. Given their shallowness and their proximity to the coast, coastal waters are subject to currents and mixing that are highly influenced by tides, waves, floods and various atmospheric factors. These features make for a mixed area where classic hydrological features are obscured by local and seasonal variation and not expressed as clearly as in offshore waters. This may be one of the reasons why oceanographers have concentrated their efforts on offshore waters and the deep sea where hydrological patterns are broader and clearer and lend themselves better to generalisations....
