Dynamics of nutrient cycling of the Valdes Bay-Punta Cero pond system (Peninsula Valdes, Patagonia) Argentine
Valdes Bay constitutes a very interesting land-sea interface (LSI) at Peninsula Valdes. A gravel bank separates the bay from the open sea. The general characteristics (physical, chemical and biological) of this ecosystem and the chemical composition of the seawater coming in and out were analyzed. N...

Valdes Bay constitutes a very interesting land-sea interface (LSI) at Peninsula Valdes. A gravel bank separates the bay from the open sea.
