Design of shallow-water optical fiber cables

SPIE Proceedings, 2004
Optical fiber cables installed in seabed were divided into the deep water optical fiber cables and the shallow water optical fiber cables (SOFC) in the light of the depth of installation. Shallow water optical fiber cables, belonged to submarine optical fiber cables, are used in not only the connection among the islands and the channels but also the ...

Optical Remote Sensing of Shallow-Water Environmental Parameters

Remote Sensing of Environment, 2000
Abstract A review of methods used for deriving seafloor reflectance and water diffuse attenuation form remotely sensed data is conducted. Emphasis is made on inverse methods applied to remote sensing of ocean properties. Then an inverse scheme for the retrieval of optically active components in coastal shallow waters is described and validated ...

Shallow water rogue waves in nonlinear optical fibers

2013 Conference on Lasers & Electro-Optics Europe & International Quantum Electronics Conference CLEO EUROPE/IQEC, 2013
The dynamics of extreme waves, often known as freak or rogue waves (RW), is presently a subject of intensive research. In oceanography, RW are mostly known as a sudden deep-water event which is responsible for ship wreakages and can be modeled by the 1D Nonlinear Schrodinger Equation (NLSE).

Sentinel-2 images deliver possibilities for accurate and consistent multi-temporal benthic habitat maps in optically shallow water

Remote Sensing Applications Society and Environment, 2021
The availability of frequently updated maps has always been the ultimate goal of remote sensing in benthic habitat data acquisition. Although the techniques offer cost and time effectiveness, the lack of consistency of inputted images can cause issues in

Hyperspectral retrievals of suspended sediment using cluster-based machine learning regression in shallow waters.

Science of the Total Environment, 2022
Remote sensing of suspended sediment in shallow waters is challenging because of the increased optical variability of the water, resulting from the influence of suspended matter in the water column and the heterogeneous bottom properties.

Determination of shallow water depth using optical satellite images

International Journal of Remote Sensing, 2009
The Penghu archipelago comprises 64 basaltic volcanic isles lying on the Taiwan Strait between mainland China and Taiwan. The water around and within these isles is shallow and poses considerable difficulty in echo sounding detection for bathymetry. Most existing bathymetry data around such areas are in water depths of greater than 5 m. Therefore, when

Optical effects from the menisci of emergent rods in shallow water

Applied Optics
The shadow created by a narrow plant stalk or rod partially submerged in water is modified by refraction through the meniscus adhering to the plant. Using laboratory experiments and Monte Carlo simulations, we investigate the structure of the caustic formed by a vertical rod and discuss several aspects of it: the caustic’s shape, brightness, and color;

Bathymetry Retrieval From Hyperspectral Remote Sensing Data in Optical-Shallow Water

IEEE Transactions on Geoscience and Remote Sensing, 2014
In this paper, an algorithm for estimating shallow-water depth from hyperspectral data is proposed. This methodology is based on the different responses of shallow-water reflectance on depth and substrate type. Two parameters-similarity coefficient and Pearson correlation coefficient-are introduced to describe the different types of responses, and a ...

Collaborative Investigations of Shallow Water Optics Problems

2003
Abstract : A combination of HydroLight and Monte Carlo numerical modeling was used to quantify the effects of water column optical properties, bottom morphology, bottom material reflectances, bottom bidirectional reflectance distribution functions (BRDFs), and external environmental conditions on remote-sensing reflectances in optically shallow waters.

The development of a towed vehicle for optical mapping in shallow water

IEEE Oceanic Engineering Society. OCEANS'98. Conference Proceedings (Cat. No.98CH36259), 2002
Environmental mapping in shallow water is normally carried out by divers. However, divers make poor mapping platforms. In order to meet these needs, a semi-submersible imaging vessel was developed. However, its operation has demonstrated some important limitations. The first was that the system could operate to only about 6 m depth.
