Tom Hull, Marine Observation Scientist, took the time to share with Zebra-Tech about a recent annual nutrient baseline survey and SmartBuoy maintenance trip and his use of Hydro-Wipers. Tom works for CEFAS – the Centre for Environment, Fisheries and Aquaculture Science in the UK.
The problem: Bio-fouling
Not very clean is it? Bio-fouling, especially among the buoys deployed closest to the shoreline, can interfere with data gathering within a fortnight. Hardly ideal when trying to run an extensive long term Eutrophication monitoring program.
As the UK’s “most diverse applied marine science centre”, CEFAS helps to shape and implement policy through their “internationally renowned science and collaborative relationships that span the EU, UK government, non-governmental organisations, research centres and industry”.
They achieve this through collecting, managing and interpreting environmental, biodiversity and fisheries data including through their annual nutrient baseline survey in the North Sea using SmartBuoys.

“Biofouling is the primary cause of data loss at our coastal sites and the use of the ZebraTech wipers has enabled us to extend the length of our deployments, significantly reducing the amount of ship time the program requires”.
“The sensors have not been damaged by the wiping action. This is particularly important for the Oxygen sensors which have a thin permeable membrane rather than a hard quartz glass”.
Hydro-Wipers are extremely robust and engineered to exacting standards by ZebraTech.
