Snorkel Sea

Snorkel (swimming)

A snorkel is a device used for breathing atmospheric air when the wearer's head is face downward in the surface water with the mouth and the nose submerged. It may be either a separate unit, or integrated into a swimming or diving mask. The integrated version is only suitable for surface snorkeling, while the separate device may also be used for surface breathing during breathhold underwater activities such as spearfishing, freediving, finswimming, underwater hockey, underwater rugby and for surface breathing while wearing scuba equipment. A standard snorkel is a curved tube with a shape usually resembling the letter "L" or "J", fitted with a mouthpiece at the lower end and made from plastic, synthetic elastomers, rubber, or light metal. The snorkel may have a loop or a clip to attach it to the head strap of the diving mask or swimming goggles, or may be tucked between the mask-strap and the head, or may be provided with its own head strap. Some snorkels are fitted with a float valve at the top to prevent flooding if the top opening is immersed, and some are fitted with a water trap and purge valve, intended for draining water from the tube.

Sea

A sea is a very large body of salty water. The term has two distinct meanings. The first is the interconnected body of seawater that spans most of Earth, known as the sea or the ocean. The second is a named body of water: usually either a marginal sea, or a large, nearly landlocked body of water.
