This copepod from Monterey Bay is less than one millimeter (1/32 inch) long.
“Traditionally, we picture a dense
phytoplankton [microscopic algae]
bloom near the surface, full of grazing copepods. Yet we’ve detected
large numbers of
copepods that appear to be feeding at the interface
between the bloom and plumes of upwelled water,” said MBARI molecular
ecologist Julio Harvey. “The copepods are at edges of the bloom, not
just inside it.”
"Near-coastal retention of
larvae affects the ecology of many marine
species. In coastal upwelling ecosystems having strong offshore
transport, larval ecology is greatly influenced by nearshore retention
in bays and in the lee of headlands. Further, frontal dynamics along the
periphery of retention zones can drive larval accumulation and
transport. "
