Sea surface carbon dioxide off the Iberian Peninsula (North Eastern Atlantic Ocean)
19 páginas, 10 figuras, 1 tabla The variability in carbon dioxide in the eastern North Atlantic Ocean was analysed during three seasons with differing hydrographical and meteorological conditions that corresponded to upwelling and downwelling.
