The CPR Towed Body has an extremely robust construction and its proven design allows deployment at speed (15 to 20 knots) from ships of opportunity where it can be left unattended and recovered prior to entering port. The CPR Body is towed with a 10mm diameter wire rope at a fixed depth of typically 10 metres. Data gathered with the CPR Towed Body is compatible with the long time series survey conducted at the Sir Alister Hardy Foundation for Ocean Science (SAHFOS).

Chelsea
Technologies Group Ltd and the Sir Alister Hardy Foundation
for Ocean Science (SAHFOS) have teamed up to offer coastal and ocean
monitoring authorities a complete equipment and service
provider for ship of opportunity based plankton sampling systems
and training in plankton analysis and taxonomy. Chelsea Technologies Group, has been supplying towed undulating vehicles, (SeaSoar, AQUAshuttle and Nu-Shuttle) for over 30 years. These systems have been fitted with a wide range of instrumentation and tools including the CTG Autonomous Plankton Sampler, a plankton sampler based on the mechanism used within the SAHFOS CPR, updated with an electric motor and indexed gauze advance. |
For fixed depth tow applications, CTG has also
supplied CPR bodies fitted with an Autonomous Plankton Sampler. These CPR bodies can also be fitted with a CTG MINIpack
CTD-F. Whether coastal and ocean surveyors are looking for plankton sampling on simple instrumented towed platforms for SOOP deployments, undulating platforms with comprehensive sensor arrays (such as the Mariner Nu-Shuttle developed for the Large Marine Ecosystem programme), or require plankton sampling systems to be fitted to onboard flow-through systems (such as FerryBox type systems), they can now obtain equipment, advice and training through the Chelsea Technologies Group.
