A reef is a bar of rock, sand, coral or similar material, lying beneath the surface of water. Many reefs result from natural, abiotic processes—deposition of sand, wave erosion planing down rock outcrops, etc.—but the best known reefs are the coral reefs of tropical waters developed through biotic processes dominated by corals and coralline algae.

PendingCN122310756ATidal cycleAtmospheric sciences
This invention belongs to the technical field of environmental multi-parameter monitoring methods, and particularly relates to an environmental multi-parameter monitoring method and system for optimizing and denoising island and reef data. Based on prior knowledge of island and reef environmental physics, an unsupervised pseudo-label generation system is constructed. A multi-parameter numerical simulation model is built based on tidal cycles, temperature-salinity-density coupling, and the physicochemical equilibrium law of dissolved oxygen-temperature-pH. Environmental time-series characteristics of measured noise data are input to generate clean simulation reference data. A self-supervised learning framework is used to pre-train the basic denoising model with the clean simulation data as a weakly supervised signal. A physics-driven multi-parameter coupling and noise decoupling mechanism is constructed, transforming the physicochemical coupling relationships of temperature, salinity, pH, and dissolved oxygen into hard constraints for the model and establishing a parameter coupling correlation matrix. Through feature decoupling branches, environmental coupling change components and noise components are separated, distinguishing between parameter coupling pseudo-noise and real noise from sensor drift and transmission interference. Denoising bias of a single parameter is corrected through coupling constraints.
