Mapping algal blooms from space with remote sensing
The quality of water bodies is a key determinant in the usability of the resource for the purpose required. It is therefore of great importance to managers of hydrologic resources to be able to confidently tell the status of their water resource. One of the major problems in the quality of surface water bodies is the blooming of algae and blue green algae.
Algal blooms can result in ecological, social and economic depreciation of lakes and reservoirs and other surface water bodies with a possible adverse effects to human health from blue-green algal toxins. Monitoring of such water bodies requires an up-to-date spatial and temporal representative water quality data and analysis.
How it works
Satellite remote sensing as an art of obtaining information about an object, area or phenomenon through an analysis of data acquired from a device that is not in direct contact with area, object or phenomenon. In addition to other environmental applications, it allows the monitoring and prediction of the quality of surface water bodies regularly.
The conventional ship-based field measurement and analysis techniques are very limited both in spatial and temporal coverage, thus the need to determine other methods to retrieve water quality parameters accurately. One of the ways to overcome this is to integrate earth observation products derived from satellite imagery in the management tools to improve the water quality monitoring and predicting programs.
Satellite remote sensing in combination with in-situ water quality data allows for the detection and monitoring of the quality of larger surface water bodies at higher spatial and temporal coverages.
LG Sonic has integrated the satellite remote sensing technique to the real-time in-situ water quality data from the MPC-Buoys to accurately map the spatial and temporal distribution of the optically active water quality parameters to help effectively monitor and improve the ultrasonic algae control systems. The MPC-Buoy combines online water quality monitoring, web-based software and ultrasound technology to provide state-of-the-art treatment against algae in lakes, ponds and drinking water reservoirs.
