Evidences of continental groundwater inputs to the shelf zone in Albardão, RS, Brazil

The southern coastal region of Brazil is highly productive and many of its ceanographic processes are still poorly understood due to a great number of forces, such as the continental input from the Plata River and Patos Lagoon, several distinct oceanic water masses, and a complex contribution from g...
