Seasonal dynamics of zooplankton in a northern Chile bay exposed to upwelling conditions

Due to the ever-increasing use of the coastline for industrial purposes, particularly by those activities that take up great amounts of sea water, it is fundamental to understand the composition of the planktonic fauna and its natural spatial and temporal variability in relation to hydrographic vari...
