Red tide monitoring and early-warning system

Abstract

The invention relates to the field of marine environmental monitoring, and discloses a red tide monitoring and early-warning system. The red tide monitoring and early-warning system comprises a data acquisition device, a data diffusion analysis device and an n-dimensional data application discrete selection model device; the data acquisition device is used for acquiring sea water quality data; the data diffusion analysis device is used for performing diffusion analysis of the acquired data and generating n-dimensional data; and the n-dimensional data application discrete selection model device is used for applying a discrete selection model for the n-dimensional data, so that whether a red tide is caused or not can be determined. By means of the red tide monitoring and early-warning system disclosed by the invention, a forming process is represented by adoption of mechanical diffusion characteristics and a statistical mode; and, with the help of the manners, such as a Markov Chain Monte Carlo simulation technology and a discrete selection model, a function of predicting the red tidy generation possibility of the system can be realized.

Description

technical field [0001] The invention relates to the technical field of marine environment monitoring, in particular to a red tide monitoring and early warning system. Background technique [0002] Due to seawater eutrophication, tides, ocean current movement and other reasons, some microorganisms and planktonic algae in seawater sometimes multiply rapidly and in large numbers. Algae contain pigments that cause seawater to change color. According to different algae pigments, seawater will turn pink, red, brown, maroon, dark green or other colors. [0003] Red tides are commonly used to describe the discoloration of seawater caused by high concentrations of algae blooms. Specific species of algae will cause the dissolved oxygen in seawater to drop rapidly, killing fish. In addition, some algae have the opportunity to have adverse effects even at low concentrations, producing toxins that pollute seafood or are harmful to humans. [0004] Prior art related to the present inv...

Problems solved by technology

[0008] Combining the practical effects of various monitoring methods, the inventor found that the existing conventional red tide monitoring and forecasting methods have clear physical meaning, but the actual operation is more difficult and costly

Most of the existing red tide remote sensing methods use empirical statistical models of one or two characteristic variables of chlorophyll or temperature or spectrum, which do not take the physiological and ecological development process of red tide into consideration, lack the basis of physical process, and have great limitations
