St. John's Buoy

A 3 metre diameter meteorological/oceanographic buoy built by AXYS Environmental Technologies of Sidney, British Columbia. The buoy is located in St. John's Bay just north of Cape Spear at the approaches to St. John's Harbour in about 160 m. water depth. The buoy's purpose is to monitor and transmit in near real time meteorological and oceanographic data in support of operational efficiency, safety and situational awareness for marine transportation. The buoy also provides a continuous data feed in support of the Science and R&D community.The buoy is capable of measuring a variety of atmospheric and surface conditions including: wind speed and direction, air temperature, humidity, dew point, barometric pressure, water temperature, current speed and direction (0.5 m. depth), wave height, direction and period as well as wave spectral information. The buoy is also equipped with an Aids to Navigation Information System (ATONiS) allowing direct transmittal of the buoy data to a ship's bridge.
