Statistical relationships between coefficients of light attenuation, scattering and backscattering at wavelength 550 nm derived from series of optical measurements performed in Baltic Sea waters are presented. The relationships were derived primarily

Statistical models of the useful and background signals forming an image of the sea bottom observed through a rough sea surface are constructed. The methods for estimating the signal-to-noise ratio in the image of the bottom with the test distributio

An algorithm is derived to retrieve the concentration of optically active materials, e.g., phytoplankton pigments, etc., from remotely measured spectra of up welled oceanic light. The algorithm takes into account sensor noise in deriving equations fo

The problem of the present-day methods for determining the sea water absorption coefficient from space is the fact that the valid signal is an order of magnitude lower than the noise. In the present work, the pulse-gating method is considered as a me

A laboratory-modeling installation for experimental investigations of light and image transfer through a wavy water surface was described. Measurements of the modulation transfer function of turbid media and a wavy surface have proved the reliability

This paper is devoted to computer simulation of random realizations of bottom images. Simulations of random images are considered to be a straightforward way to predict bottom visibility under realistic conditions. A simplified version of a bottom im

We consider the inverse problems in the retrieval of the water's inherent optical properties (IOP) and the properties of the hydro-physical processes taking place in a water body using the returned signal of an oceanic lidar. An algorithm for the ret

The possibility of the retrieval of the water's inherent optical properties (IOP) from Secchi disk observations is discussed. The paper directly addresses objections to the use of Secchi disks raised by Preisendorfer in 1986. A new version of Secchi

The long-term goal of the Project is to develop robust inversion algorithms to extract estimates of the optical and physical properties of sea water layers, the sea floor, and the sea surface from LIDAR (Light Detection and Ranging) returns, and opti
