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

Small-scale horizontal heterogeneites or patches of bioluminescence intensity and sound volume back scattering strength (SVBS) were studied in the central part of the Black Sea in October, 1989. Bathyphotometric casts and measurements of SVBS, were taken every 3 minutes in the surface layer (0–20 m) over a period of several hours from a drifting vessel. Casts were accompanied by temperature profiles and zooplankton sampling. Measurements were carried out during the day and night periods. From adaptive spectral analysis it was shown that the horizontal dimensions of the bioluminescent and SVBS heterogeneities were between 75 to 1500 m and 20 to 443 m respectively. In the case of zooplankton biomass the dimensions were 85 to 818 m and 80 to 1800 m for the temperature field. Physical and dynamical factors dominate in the formation of small-scale spatial heterogeneity of the studied fields. Biological factors, such as diel vertical migrations, trophic interactions etc. will also contribute to the formation of patches at night.
