Mobilis DB 8000 UKMO-OC

3m Diameter Data Buoy Platform

Download DataSheet

DB 8000 UKMO-OC is a meteorological/oceanographic data buoy capable of carrying a large number of sensors / equipment packages along with a large solar panel array and battery bank.

Based on the DB 8000 data buoy platform, it comprises a 3m diameter hull constructed from multiple-section polyethylene floats that are bolted around a central steel structure, with through-hull access for underwater instrumentation and cabling.

The large marine grade aluminium towers of the DB 8000 allow its large equipment payloads to be placed in a protected location. The UKMO-OC buoy has been designed with a larger diameter tower to allow more equipment to be installed and enable technicians to access underwater instrumentation from inside the tower. The meteorological sensors and antennae are mounted within a strong protection ring whilst still allowing exposure to the elements that they are installed to measure.

The UKMO-OC buoy contains a meteorological sensor suite measuring wind speed and direction, air temperature, relative humidity, and barometric pressure. It also has an oceanographic sensor suite measuring salinity, depth, dissolved oxygen, chlorophyll ‘A’, turbidity, dissolved organic matter, and nitrates. A spectral wave sensor outputs wave height, wave period and direction. Data is transmitted ashore using an Iridium satellite communication system.
