Coastal Buoy - Data Buoy

OVERVIEW

  • Reliably collect near real-time data unattended from coastal waters for prolonged periods of time
  • Proven instruments provide accurate oceanographic and meteorological data
  • Easily transported by road and deployed from small craft


REAL-TIME COASTAL MONITORING PLATFORM

Data Buoy II (DB II) is a real-time coastal monitoring platform designed to be deployed for many unattended months in a range of sea conditions.

DB II measures oceanographic and meteorological conditions in coastal waters and sends data to a land based server by means of standard cellular or global satellite telemetry.

DB II's have been successfully deployed in South-African waters collecting data for factories and oceanographers.
