Following a successful test in which Cabled UV prevented marine growth on oxygen sensors and cameras deployed in situ for six months, Oregon State University (OSU) has purchased 20 Cabled UV biofouling control systems. Cabled UV was selected for the Endurance Array, a multi-scaled array developed under the Ocean Observatories Initiative (OOI), for its suitability for fragile and complex surfaces. Assistant Professor Jonathan Fram explained:

Each cruise is expensive, so we need instruments deployed in the photic zone to last the full six months without significant fouling. Six weeks into our test, the unprotected oxygen sensor was clearly fouled while the UV protected sensor is still producing reasonable data. We intend to deploy the UV device with all of our upper water column oxygen sensors in the future, and will experiment with the UV light on our other optical instruments.

OSU’s trial is the latest in a string of in situ deployments successfully completed through the use of AML’s biofouling control solutions, Cabled UV and UV•XchangeTM.
