Submersed Aquatic Vegetation(SAV)

Learn the Basics

Submersed Aquatic Vegetation(SAV)Researchers and resource managers use BioSonics echosounder systems and software to assess submerged aquatic vegetation in both marine and fresh water environments. Common uses include locating and quantifying critical habitat species such as eelgrass for protection purposes, and calculating accurate canopy heights and densities of invasive species such as Eurasian Watermilfoil. The system can be deployed from virtually any size watercraft in depths as shallow as one meter. The echosounder system automatically records bottom depth and plant canopy height and density. All data is time-stamped, geo-referenced and digitally stored. Surveys can be conducted by a single operator and do not require sophisticated training.

How It Works

SAV HOW IT WORKS PLANT MAPA high frequency transducer is used to collect fine resolution hydroacoustic data and detect the tips of submersed vegetation growing on the seabed. The narrow ,focused acoustic beam of sound energy can penetrate the vegetative canopy and detect the actual bottom below. Specialized software using multiple algorithms effectively determines the bottom and plant canopy levels and calculates the percent coverage in each sample report. The processed data are exported as geo-referenced CSV files which can readily mapped using GIS software tools.
