Development of Remote Sensing Assisted Water Quality Nowcasting and Forecasting Models for Coastal Beaches
A remote sensing assisted water quality modeling framework is developed in this dissertation for nowcasting and forecasting recreational water quality of Holly Beach in Louisiana, USA. The modeling framework is composed of four models/systems: (1) an Artificial Neural Network (ANN) model (Model 1) …

Lipopolysaccharide in marine bathing water; a potential real-time biomarker of bacterial contamination and relevance to human health
The quality of marine bathing water is currently assessed by monitoring the levels of faecal indicator bacteria. Among other drawbacks, results are retrospective using the traditional culture based methods. A rapid method is thus needed as an early warning to bathers for bacterial contamination in …
