If you are diving wearing an exposure suit, what should you do to control buoyancy as you descend?

When descending while wearing an exposure suit, managing buoyancy is crucial for a controlled dive. Adding air to your buoyancy device is the correct method to achieve proper buoyancy control.

When descending, especially in an exposure suit, which can trap air and thus cause an increase in buoyancy, adding air to your buoyancy control device can help offset this effect. This ensures that you are descending at a controlled rate rather than floating upwards due to positive buoyancy. Proper use of the buoyancy device allows for fine-tuning your buoyancy during the descent, helping you maintain a stable position underwater.

In contrast, the other options involve actions that would generally increase buoyancy or are unsuitable for controlled descent. Adding weight to your belt could lead to sinking too rapidly and could be dangerous. Deflating your buoyancy device would reduce your buoyancy further, which may lead to an uncontrolled descent. Removing weight from your suit is not a practical solution during a dive and may disrupt your overall buoyancy balance. Thus, managing buoyancy with your buoyancy control device is essential for safe and effective descent.
