CMAR - Coastal Marine Applied Research: Equipment (hire available)

CMAR has a comprehensive range of equipment for survey, hydrodynamic and morphological measurements. All equipment listed is available for hire.

CMAR has a comprehensive range of field equipment for survey, hydrodynamic and morphological measurements. Our technical and academic staff are highly experienced in the set up, deployment and retrieval of this equipment, and we've published a number of peer-reviewed journal papers using the fantastic data they acquire.

We also have a rapid storm response unit, which can mobilise and deploy a range of our instruments at short notice. Over the last three years this has recorded data from some of the largest storms to have hit the British coastline since records began.

Below is a sample of the equipment that is available for project use and hire from CMAR. Please contact us for further details, or for a full instrument roster.

Lagrangian surface current drifters

GPS drifters: used to measure lagrangian current velocities, with capability up to several kilometres from shore. We have used these extensively for the measurement of nearshore rip currents and for the validation of hydrodynamic models. We have a large fleet of drifters available, with on-board logging or live-feed data telemetry up to 2km from shore

Rapid Storm Response Unit

To further our understanding of the impacts of storms on our coastline, we have developed the rapid storm response unit. This vehicle has everything we need to go out and monitor hydro and morpho dynamics during extremely high-energy conditions at the coast. The unit can be mobilised at short notice – an essential prerequisite to capturing pre, during, and post storm conditions. Over the last three years this has recorded data from some of the largest storms to have hit the British coastline since records began.
