What are the two positions for submersion?

The two positions for submersion are typically understood as horizontal and vertical. When discussing submersion in diving or aquatic environments, these two orientations are crucial for understanding how a diver interacts with water and the effects of buoyancy, pressure, and movement.

In a horizontal position, the diver is streamlined, which allows for efficient movement through the water and helps to reduce drag. This position is commonly used when swimming or when a diver is aiming to cover distance with minimal effort.

Conversely, the vertical position is often adopted for activities such as diving or when in a standing position in the water. It can also be significant for certain maneuvers, such as climbing or descending underwater.

Understanding these two positions allows divers to maximize their efficiency and safety during water activities. Knowing how to transition between these positions effectively is essential in various diving scenarios, including managing ascent and descent in the water column.
