GEOLOGIA GENERAL. 1er CURS. GRAU EN BIOLOGIA. 20137Equatorial UpwellingAs surface water diverges, sea level falls, surface layer thins and cold water upwells
GEOLOGIA GENERAL. 1er CURS. GRAU EN BIOLOGIA. 20138Coastal UpwellingCoastal divergence results in upwelling as cold water rises to replace surface water
GEOLOGIA GENERAL. 1er CURS. GRAU EN BIOLOGIA. 20139Coastal upwelling and downwellingEkman transport moves surface seawater onshore (downwelling) orOffshore (upwelling)
