Open WL Archief (OWA)

Over het archief

Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.

Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

Abstract

Three mysid and three calanoid copepod species dominated the mesozooplankton in the Sundays River estuary, South Africa. Mid estuary, there was considerable overlap in the spatial and temporal distribution of species. Mesozooplankton abundance was lowest during winter. Microzooplankton, consisting of ciliates, zooflagellates and rotifers, was most abundant in the middle of the estuary. Rotifer abundance was lowest in winter and autumn. Other microzooplankton showed no seasonal variation. Phytoplankton was dominated by micro- and nanoflagellates, dinoflagellates and euglenoids, but diatoms were very abundant after a flood. Chlorophyll a concentrations were greatest in the middle and upper estuary, but there they showed no seasonal fluctuations.
