Scuba Diving Travel

Channel Islands, Southern California:
Among scuba divers California is certainly famous for its Channel Islands along the coastline between Los Angeles and San Diego. Divers find nomally ideal conditions with clear water. Many tour operators offer diving lessons and tours like shark diving and feeding.

Farallones Islands, Northern California:
Just north and west of San Francisco Bay a large expanse of Pacific Ocean along with nearshore tidal flats, rocky intertidal areas, wetlands, subtidal reefs, and coastal beaches was designated in 1981 as Gulf of the Farallones National Marine Sanctuary.
This is considered an optimal location for seeing the Great White Shark; water temperatures are usually cold.

Way deeper than 130 feet lies Pulley Ridge, Florida
Pulley Ridge is a 100+ km long series of north-south trending, drowned, barrier islands on the southwest Florida Shelf approximately 250 km west of Cape Sable, Florida (WNW of Dry Tortugas).
The ridge is a subtle feature about 5 km across with less than 10 m of relief. The shallowest parts of the ridge are about 60 m deep. Surprisingly at this depth, the southern portion of the ridge hosts an unusual variety of zooxanthellate scleractinian corals, green, red and brown macro algae, and typically shallow-water tropical fishes.
From the U.S. Geological Survey's staff's scientific perspective of a structure built from hermatypic corals, southern Pulley Ridge may well be the deepest coral reef in the United States.

Scuba diving became a public sport not until the mid 50's / early 60's even if the technical base was invented way before.
It was Jacques Cousteau und Emile Gagnan who invented in 1942 the technique to control the air pressure of a diver's inhaled air by developing a type of on-demand valve.
SCUBA stands for: 'Self Contained Underwater Breathing Apparatus' and was coined by the U.S. Navy end of the 1930's/early 40's.
