The OSIL Profiling Fulmar, Skua and Albatross Buoys are manufactured using rotationally moulded polyethylene hulls, which are foam filled for added security. The hulls are constructed around a galvanised steel core, which has a large hole through the centre which allows the passage of instrumentation from the winch down through the water column to the seabed. The winch automatically profiles from just below the surface to just above the seabed (maximum 100m).
The system is normally supplied with a water quality sonde (including CTD, DO, pH/ORP, Turbidity, Chlorophyll) or oceanographic CTD which is connected to an internal winch designed for the marine environment that can provide automatic profiles every 3-8 hours. Other sensors can be connected at the client’s request.
Depth is controlled by an on board echosounder and the datalogger automatically compares the echosounder data with the profiling sensors depth sensor to avoid the seabed. The buoys are moored in a fixed position with a dual point mooring.
The profiling option can be added to our range of MetOcean Buoys adding further measurement capability for options like current speed/direction, wind speed/direction, temperature, humidity, pressure, rainfall, solar radiation as well as a GPS locator. All buoys are fitted with solar panels, navigation/warning lights and other markings as necessary. A range of telemetry options are available (UHF/VHF, GSM, GPRS, Satellite), selected to suit both the location and application requirements. OSIL provide a complete data telemetry solution, including either desk top or web-based software packages to access the data.
