Relationship between zooplankton biomass and continental water discharges in the southern Gulf of Mexico (1984-2001)

Zooplankton biomass is recognized as an important indicator of secondary production, its spatial and temporal variation in neritic zones is particularly affected by discharges of the rivers, and the spatial-temporal effect of continental water discharges on the distribution of zooplankton biomass in...
