David O asked:


If the force on the tympanic membrane (eardrum) increases by about 1.50 Nabove the force from atmospheric pressure, the membrane can be damaged. When you go scuba diving in the ocean, below what depth could damage to your eardrum start to occur? The eardrum is typically 8.20 mm in diameter. Take the density of seawater to be equal 1.03\times 10^3 kg/m^3.

Im going on a vacation, never been scuba diving before. Where is there a place to rent scuba gear for a reasonable price? I dont want a pool or set up atmosphere- I’m looking for reef and actual marine wildlife. I’m assuming these are guided experiences. About 100 mile radius from Orlando. Thank you for any help.

The earliest years of recreational scuba training were rigorous and labeled too militaristic by some educators and trainers. They argued that easier training would open diving to a greater portion of public, and make it more popular and profitable. This encouraged some scuba manufacturers, who needed a growing diving population to support their product sales, to actually develop a number of the earlier diver training courses. This led to the growth of the recreational diving public, which, coupled with the establishment of private training organizations, succeeded in bringing scuba diving to everyone. Nowadays almost all of us can participate in a diving course. In may cities we have a divers clubs associated with schools, colleges, universities and other. However, there are three obvious limitations connected with participating in a diving course. First one refers to one’s own health, which conditions may sometimes be insufficiently well to perform an underwater activities. Second one – is pure material reason called money. Diving courses, while not performed on behalf of university, or school, are in general relatievley expensive. The third, and the last limit is our will, which sometimes may happen to be not strong enough to help us stay.

The Great Barrier Reef is considered to the ultimate in scuba diving adventures in the world which offer same excitement to experts as well as beginners. So what is so special about the Great Barrier Reef ? First of all, the size. Its simple huge - stretching over 1400 miles along Australia’s East Coast. It is not only the largest reef system in the world, but many consider it as one of the most beautiful too. If this has been your dream to visit this natural wonder, here are some tips for the first-time traveler :

The Location of the Reef

Situated near Queensland in Australia, the Great Barrier Reef is about 185 miles away from the mainland on the southern side. It is about 12 miles away from the shore on the northern side. It is about 50 miles wide at the northern side - the widest stretch. What can you expect to see at the Great Barrier Reef. The amazing variety of plant and animal life which have made its home here is mind-boggling. You can, actually see about 4000 species of mollusks, more than 1000 species of fish, about 380 species of coral, 500 species of seaweed, six varieties of sea turtles.

How to Get to the Barrier Reef

There are daily flights to Australia from the West Coast in the United States. When you reach Australia, you may have to take a small connecting flight to land near one of the gateways to the reef. Generally people go for Cairns and Townsville, two tropical cities located near the northern side of the reed. The other gateway is at Gladstone and Bundaberg, located near the southern side of the reef.

The Ultimate Scuba Diving Adventure

The calm and lucid waters around the reef make it the best location for scuba diving in the world. Water may run deep at certain places, but is generally moderate for amateurs to dive in. For beginners, diving should be in shallow waters - about 60 feet in depth. However for experts, there are reefs around the Coral Sea where the depth is about 300 feet.

To go through one of the best scuba diving experiences, you can board one of the popular ‘live aboard’ boats. These specialized boats take visitors right where the action is. Many such boats have convenient luxury amenities and can organize boats to take divers right at the center of the reef. There are day boats available for day-time scuba diving. These day boats take visitors for 4 to 5 hour trips into the reef. Even local resorts organize these day boats for their guests.

Finding a ‘Dive Island’ Resort

Resorts located in small islands around the reef are capable of organizing scuba diving trips for the guests. They provide convenient access to the reef and are great for visitors looking for a scuba diving adventure. Generally these resorts are situated in Lizard, Green, Lady Elliot, and Heron islands. ‘Cod Hole” - a popular diving site is situated off Lizard Island.

Best Time to Visit the Reef

Anytime of the year is considered to be safe and suitable to visit the reef for scuba diving. This is because of the nature of the water which is normally calm and steady. The Australian summer is considered to be popular - which is between December and March. Because of the tropical climate, the temperature usually hovers around 70 to mid-80s.This makes a visit to the Great Barrier Reef and its surrounding cities pleasant at anytime of the year.

Gozo is an island in the Mediterranean Sea. Gozo is 67 square kilometres in size, which is about the same size as Manhattan. The island of Gozo, with its three hilled island, is greener and more picturesque than Malta.

It looks like the Garden of Eden with all the wild flowers, birds and other animals in its best months which are October to May. Its underwater landscape is spectacular and the waters surrounding the island are of the most beautiful blue. Gozo is rated as the best scuba diving holiday spot in the Mediterranean where divers can enjoy drop offs, reefs, and caves.

Ramla beach is one of Gozo’s nicest beaches Ramla bay is in fact reputed to be the place where Ulysses, the heroic Greek warrior, met the enchanting queen Calypso

The red sand beach at Ramla Bay is among the nicest in the Mediterranean. Marsalforn and Xlendi near to Victoria are the main resorts. Xlendi is one of the most popular places in Gozo.

The island is also known for it’s lace and for its woollen goods. There are also many small stalls to buy them from. All over the island are small shops selling beautiful lace items and in some of them can be also seen old ladies showing how the lace is done. Knitted jackets are also on sale everywhere.

Dwejra is the Fungus Rock. In Maltese it is called Il Gebla tal-General General’s Rock. It is called in remembrance of the Italian General who centuries ago fell to his death while supervising quarrying activities in the area. History tells us that a special plant with medicinal and healing properties used to grow on Fungus Rock and because of this the Rock used to be heavily guarded during the time of the Knights of Malta. Anyone caught stealing the crop was sentenced to death.

Ghantija Temples are two massive megaliths which were carved into temples by the pre-Phoenician Gozitans between 4,100 and 2,500BC. There now stand on the island as mysterious monuments to a bygone age. Legend has it that they were transported to the island by a giantess called Sansuna. The name of the site, Ghantija, which means giant. Large stone balls in the area, however, have led archaeologists to conclude that the massive blocks were rolled into place atop these. The two temples have a common facade but each has a separate entrance one is larger than the other. It is believed both originally had roofing made of wooden beams, and that sacrifices of animals were made in the temples during rituals.

I have a friend who knows everything about everything. However, this time I think he has overstepped his boundries. He has assured me that it doesnot matter what type of SCUBA tank you are using that the maximum time is one hour. I think he has let his alligator mouth overload his hummingbird ass.
