How long can BT buoys operate before they need to be replaced?

BT buoys, which are used to monitor water temperature, are designed to operate for a limited duration before requiring replacement. The correct answer is based on the typical operational lifespan of these buoys, which is 12 minutes. This short duration allows them to effectively collect and transmit data but necessitates prompt replacement to maintain accuracy and reliability in monitoring conditions.

In the context of naval operations, ensuring accurate temperature readings is vital for various missions and tasks, such as underwater navigation and research. The relatively brief operational time aligns with the need for frequent checks, as environmental conditions can change rapidly. This emphasizes the importance of timely maintenance and replacement of the equipment to ensure ongoing collection of important data.
