What is one method of searching in rescue operations?

In rescue operations, using sonar or thermal imaging cameras (TIC) is a highly effective method for searching, particularly in water scenarios. Sonar technology allows rescuers to detect and locate individuals beneath the water's surface by emitting sound waves and analyzing the echoes that bounce back. This method is especially valuable in murky or deep water conditions where visibility is severely limited.

Thermal imaging cameras complement this by detecting heat signatures. People in the water emit body heat, which can be picked up by TIC even in low visibility conditions, such as night time or fog. The combination of these technologies significantly enhances the chances of successfully locating individuals in distress, providing a reliable means of gathering data on their location and condition without needing to rely solely on visual cues.

While other methods like vocal signaling, hiking, and visual scanning can also play roles in search and rescue operations, they might not be as effective in specific scenarios where the environment limits visibility or accessibility. For instance, vocal signaling may not reach individuals who are unable to respond due to distress, and visual scanning is often hindered in poor visibility conditions. Hence, sonar and TIC are invaluable tools that enhance search operations in challenging situations.
