Monitoring HABs in Spain

摘要

Situated in Galicia in the northwest of Spain, the Ria de Vigo is a river valley that has sunk tectonically and has been flooded by the sea. The ria is connected to the open sea via a narrow northern channel and a wider and deeper southern channel (see Figure 1). Due to the low tidal circulation, the Ria de Vigo can be susceptible to harmful algal blooms (HABs), which can kill fish, contaminate seafood with toxins and fundamentally alter whole ecosystems.
