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

Marine biogeochemistry deals with diverse variables, many of them (especially biological rates) difficult to measure. For parameter estimation and data assimilation, differences between predicted and measured values of these variables must be summarized by a single misfit number. A ‘correct’ measure of misfit incorporates choices about issues that include (1) the relative importance of deviations from a small and a large predicted value; (2) the relative importance of small and large deviations from a predicted value; (3) the relative importance of deviations above and below a predicted value; (4) comparing discrepancies measured in intrinsically different units, like concentrations and rates. Recent papers on estimating ecological parameters represent a variety of different choices. This paper uses a data set and model for the subtropical North Atlantic to demonstrate that the choices made for defining misfit can have a large influence on the ‘best’ estimate of biogeochemically important fluxes and concentrations.
