Cornwall Inshore Fisheries and Conservation Authority has recently taken delivery of a Scientific Echo Sounder to help them manage seagrass conservation.
The new BioSonics MX Scientific Fisheries Echo Sounder will complement IFCA’s equipment capability in conserving seagrass in marine protected areas.
Colin Trundle, Principal Scientific Officer at Cornwall IFCA, says: “We are looking at mapping the extent and density of seagrass in four marine protected areas in Cornwall, to ensure our management is appropriate and effective.
“Previously, we had to rely on 2D imagery and the new equipment will give us the 3D capability to see the canopy height and density, and also estimate the sea bed substrate type as well. “
Seagrass is vital for climate change as well as being an essential marine habitat. It has a considerable part to play in absorbing carbon dioxide from the atmosphere.
The Biosonics MX Aquatic Habitat Echo Sounder, supplied by Hayle-based survey support company Swathe Services, will be used to simultaneously map submerged seagrass vegetation as well as collect bathymetry data on the seabed and classify substrate.
BioSonics scientific echosounders provide an in-depth understanding of the underwater environment for assessment, research and management.
