OSIL (Ocean Scientific International Ltd.) have recently supplied the Countryside Council for Wales (CCW) with a data collection system for background monitoring at Skomer Marine Nature Reserve. The system consists of an OSIL Shearwater Data Buoy, fitted with a Campbell CR200 Data Logger and a VHF Omi-directional Antenna.  When deployed the 1.2 diameter buoy will be attached via a data cable to a customised OSIL Seabed Mounting Frame. The octagonal mounting frame has been fitted with a YSI 6600 Multiparameter Sonde which will be primarily monitoring CTD, DO, turbidity and chlorophyll. Once collected, the data will be transmitted back via VHF to Skomer’s Ethernet network where it will be downloaded onto a PC and later published on a website for public viewing. The buoy will be attached to the seabed by a two point mooring to prevent excessive movement of the buoy due to the extremely harsh environment of the nature reserve.
