As defined by Jerlov, type I water is the clearest, consistent with subtropical open ocean (“blue”) environments, while type III water is most turbid, typical of river outflows and highly productive coastal waters. The subtype IA is closest to but slightly more turbid than type I, while the Jerlov subtype IB is closest to but slightly less turbid than type II. Fig. 5. View large Download.
The ROMS in this configuration uses Jerlov’s (1968) optical classification of water type I, which assumes the most transparent water. The sensitivity of the result to the choice of different water types (e.g., Shinoda 2005; Li et al. 2013) is not considered in this study. The simulation period spans 1 month from 14 November to 13 December 2011, covering both the convectively suppressed and.
Irradiance The Western Mediterranean waters belong to the optical water types lB-Il, according to Jerlov's optical classification for the upper 10 meters of the surface layer2 (Fig. I). A later attempt by Jerlov'4 to extend his original classification to greater water depths cannot be characterized as being successful, judged from the present data set (note the deviation for 371 nm at 50 ni.
Jerlov’s theoretical and experimental work on ocean optical and related processes helped form the foundation of modern ocean optical research. He proposed the concept of an optical ocean water mass classification and the Jerlov water types are familiar to many outside of the ocean optics community. His book, Marine Optics, published in 1976, remains widely referenced and is considered.
General optical water mass classification schemes have also been used for several decades (Jerlov, 1976; Morel and Prieur, 1977), but a robust, quantifiable scheme is required to optically identify and characterize complex coastal water types. The common distinction between Case 1 oceanic and Case 2 coastal waters is not adequate. By coupling new in situ optical measurements with advances in.
Unlike the other components of heat flux (which warm or cool solely the surface of the model ocean), the incoming shortwave radiative heat flux is allowed to penetrate downward a distance that depends on a double exponential function determined according to the Jerlov classification of the waters, as given by Paulson and Simpson.
Abstract. A simple solar heat input model applicable to a stagnant, incompressible and horizontally stratified ocean is presented. The model demands only a single optical input parameter in order to work.
Nevertheless, the Jerlov classification scheme still is useful, especially in applications where estimates of performance in typical water conditions are required.
This has resulted in the well-known Jerlov's optical classification: a classification which remains purely phenom- enological in the sense that only the variations in the optical properties are quantified, whereas the causes of these vari- ations are not identified and quantitatively assessed. Meanwhile, biologists have sought for empirical relation- ships between easily measurable optical.
Description: Since the publication of Jerlov's classic volume on optical oceanography in 1968, the ability to predict or model the submarine light field, given measurements of the inherent optical properties of the ocean, has improved to the point that model fields are very close to measured fields. In the last three decades, remote sensing capabilities have fostered powerful models that can.
