Abstract

Copepod nauplii were collected from continental shelf waters off Cape San Blas, Florida, off the Mississippi River delta, and off of Galveston, Texas. There was significant interannual variability in naupliar concentrations within the region around the Mississippi River delta; naupliar concentrations in the upper 10m decreased in the onshore-offshore direction in 2 of 4 comparisons; naupliar concentrations in the upper 10m differed regionally in 2 of 3 comparisons; and the naupliar concentration was correlated with chlorophyll concentration in 4 to 5 comparisons. Maximum concentrations of nauplii within a water column were 2-10 times greater at stations influenced by the Mississippi River plumes than in the other 2 regions, attributed to vertical stratification imparted to the water column by the inflowing low salinity water. -from Authors
