Acoustic and optical tools
Our research vessel, the Cefas Endeavour, is
equipped with the latest sonar technology, and some of this
equipment can be supplied for use on other survey vessels.
Our range of acoustic tools include:
- echo sounders: three frequencies for fish abundance estimation
and behaviour studies
- sonar: for monitoring fish distribution and tracking tagged
fish
- multi-beam swathe sonar: for 3-D seabed mapping
- digital dual-frequency side-scan sonar: for detailed seabed
mapping
- hydrographic echo sounders: for collecting high-quality ground
discrimination data
- acoustic ground discrimination systems
- high-resolution, shallow water multi-beam bathymetry
system
To check actual details on the seabed, we use a optical tools
and other techniques. These include:
- optical methods, for example drop-down video cameras, a
video sledge and sediment-profile camera
- quantitative methods: Hamon, Shipek and Day grabs to collect
sediment and mud
- qualitative methods, for example beam-trawls and a range of
fishing gear.
Our team of experts can advise and assist on survey design,
planning and the analysis of outputs.
