1、Emerging ocean observations for interdisciplinary data assimilation systems Original Research Article

Journal of Marine Systems, Volumes 40–41, April 2003, Pages 5-48

Abstract

Identification, understanding, and prediction of many interdisciplinary oceanographic processes remain as elusive goals of ocean science. However, new ocean technologies are being effectively used to increase the variety and numbers of sampled variables and thus to fill in the gaps of the time-space continuum of interdisciplinary ocean observations. The formulation, accuracy, and efficacy of data assimilative models are highly dependent upon the quality and quantity of interdisciplinary observational data. In turn, the design of optimal sampling networks will benefit from data assimilative-based observation system simulation experiments (OSSEs). The present contribution, which is directed toward both modelers and observationalists, reviews emerging interdisciplinary observational capabilities and their optimal utilization in data assimilative models.

2、The evolution of the instrumental technique in underwater optics Original Research Article

AbstractAbstract | ReferencesReferencesAbstract

Thanks to the use of the photovoltaic cell significant pioneer work in underwater optics was made in the 1930's. Among the principal instruments designed at that time, the beam transmittance meter and the scatterance meter were introduced in oceanographic studies by Hans Pettersson. The development of a technique with photomultiplier tubes provided a new impetus in optical research particularly in the study of scattering problems. A distinct advantage with photomultiplier tubes is that their high sensitivity makes possible the use of interference filters by which almost monochromatic measurements are obtained and the treacherous “band width error” occurring with broad filters is avoided.

An equipment of in situ instruments fit for routine observations is described, namely an irradiance meter, a beam transmittance meter and a scatterance meter which measure the spectral energy distribution, the total attenuation coefficient and the total scattering coefficient respectively. The meters are provided with simple depth sensing units and records are obtained with an x−y recorder.
