Hydrographic conditions and mesozooplankton species distribution in the Bay of Biscay shelf during spring 2004

Mesozooplankton community structure on the southern Bay of Biscay shelf and its relationship with environmental conditions was analysed during spring 2004. According to thermohaline characteristics, we observed two frontal zones along the shelf (around 7° and 3°W) that gave rise to three distinct hy...
