Search and

Rescue (SAR)

The real time observations by HF-radar can contribute to get more reliable information on ocean surface currents and waves to support Search and Rescue.

The quality checked real time data can be assimilated into hydrodynamic models and existing prediction systems. This improves the reliability of the drift prediction. WERA data is very useful for search and rescue operations when used for object or particle tracking to narrow down the search radius for people lost overboard or for lost containers.

WERA can save lives.
