Salt water is denser than fresh water, hence, it requires more weight to sink in salt water.
The bubbles exhaled by a scuba diver grow as they approach the surface of the ocean due to the decrease in pressure. As the diver ascends, the surrounding pressure decreases, causing the gas in the bubbles to expand. This expansion makes the bubbles appear larger as they rise to the surface.
When a scuba diver descends into deeper waters, the pressure increases, causing the volume of air in their scuba tank to decrease according to Boyle's law. This is because as pressure increases, the volume of a gas decreases proportionally, illustrating Boyle's law in action.
Being neutrally buoyant underwater allows a diver to hover effortlessly at any depth without sinking or floating to the surface. This conserves energy and helps prevent damage to fragile marine ecosystems by minimizing contact with the bottom. Additionally, it enhances dive safety by allowing better control of buoyancy and maintaining proper depth.
A buoyancy compensator, typically worn by scuba divers, is a piece of equipment that helps control the diver's buoyancy underwater. It can be inflated or deflated to adjust buoyancy and maintain a desired depth. It also provides a means for attaching other diving equipment and can serve as a flotation device on the surface.
Right at the surface of the ocean, the pressure is just the same as the air pressure at sea level; that is, one "atmosphere", or about 14.7 PSI (Pounds per Square Inch). But water pressure increases with increasing depth: For each foot of depth, the water pressure increases by 0.445 PSI. SCUBA divers, who need to be very aware their depth because of this pressure effect, often use this rule: Every 33 feet of depth, water pressure increases by one "atmosphere" (14.7 PSI). So, for example, at 66 feet the pressure on a diver is three atmospheres: There's one atmosphere of pressure from the air, and two atmospheres from the water.
A scuba diver is a human who enjoys scuba diving. Therefore, a scuba diver has a spine and is a vertebrate.
It depends: for instance, a fish swims in the ocean. A ship sails on the ocean. The scuba diver descended into the ocean.

Scuba Bob's Ocean Quest - 2006 Adaptive Diver Certification Part 2 4-3 was released on: USA: 2009
Becasue if a SCUBA diver didn't go underwater, they really wouldn't be a SCUBA diver. SCUBA stands for Self-Contained Underwater Breathing Apparatus.
Elaine Rowsby-Tucker is the best scuba-diver in the world!!!!!
The current world record is 313 meters.
There are several sports magazines which specifically feature scuba diving, these are Scuba Diving, Diver, Sport Diver, Dive Girl, Explore Underwater and Seaduction.

That is a Scuba diver flag, meaning "diver down."
