Manta Ray Night Dive
A manta ray night dive is a scuba diving or snorkeling excursion to view manta rays at night. This activity is especially popular on the big island of Hawai'i, where divers and snorkelers can observe manta rays during their nocturnal feeding in their natural habitat. Description Depending on the amount of microscopic plankton present, the number of manta rays will vary. Some days no manta rays are seen while on days with high plankton levels upwards of a dozen may be present. While diving, scuba divers shine lights up - known as "bonfire" or "campfire" diving - while snorkelers shine them down creating a column of light which attracts millions of minuscule plankton, which in turn attracts the manta rays. A popular site is just off the coast of Hawaii (island), Hawaii Island called Garden Eel Cove, as well as the Kona Surf Hotel. Located just off the coast of Keahole Point (near the Kona International Airport), it attracts scuba divers for the abundance of manta rays. Its offic ...

Scuba Diving
Scuba diving is a Diving mode, mode of underwater diving whereby divers use Scuba set, breathing equipment that is completely independent of a surface breathing gas supply, and therefore has a limited but variable endurance. The word ''scuba'' is an Acronym#Normal case and acronyms, acronym for "Self-Contained Underwater Breathing Apparatus" and was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, affording them greater independence and movement than surface-supplied divers, and more time underwater than freedivers. Although the use of compressed air is common, other gas blends are also used. Open-circuit scuba systems discharge the breathing gas into the environment as it is exhaled and consist of one or more diving cylinders containing breathing gas at high pressure which is supplied to the diver at ambient pressure through a diving regulator. They may include additional cylinders for range extension, de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
