How to Help Preserve Marine Life Through Scuba Diving?
Issues such as global warming and environmental degradation have stirred many sectors of society towards social responsibility and the stewardship of our natural resources. Organizations such as REEF (Reef Environmental Education Foundation) and NARC (Neptune's Army of Rubbish Cleaners) are grass roots environmental agencies that organize research and educational programs, including clean up activities that aim to entice divers, marine researchers and even non-divers to become stewards of aquatic ecosystems and marine life per se. If you are a diving enthusiast and would like to participate in the global effort of preserving marine habitats, here are a few noteworthy activities that you can engage into.
It commences from land. The activities of man on land will eventually affect the state of marine life in one way or another. So why not join the local scuba diving community in the conduct of coastal clean-up activities that are organized every year. This can help reduce the volume of hazardous wastes infiltrating marine habitats.
Taking whatever your hands can carry. Reef clean-up involves the removal of non-biodegradable materials without disturbing the fragile balance of marine flora and fauna thriving in these biotic underwater habitats. Garbage collected from reefs can be further segregated, recycled or reprocessed to prevent its unwanted return to the ocean.
Surveying Fish and Reef Species. Besides the removal of trash from the waters, REEF also maintains a growing database of fish and other marine species with their corresponding abundance scores. This is accomplished through the Roving Diver Volunteer Program that beckons certified scuba divers inclined to multi-task, as they go about with their individual, recreational diving pursuits in the waters of Canada and the US, with the survey of marine species and recording of its manifestation based on the inputs required by a proforma survey sheet. Said activity not only seeks to provide a dynamic, primary data for marine research and product development but also fosters a profound understanding and appreciation of marine life for volunteers.
Think you have got what it takes to become a steward of marine ecosystems? Non-divers can contribute to this pursuit by participating in coastal clean-up activities. Nonetheless, certified scuba divers can do so much more to this end being in close contact with coral reefs and other reef formations. This can be conducted without upsetting the fun part of any recreational scuba dive with the simple retrieval of any garbage you find on the reef. Moreover, becoming a REEF surveyor puts more meaning to the definition of marine life stewardship. Just make sure you're properly geared up with the right scuba equipment to keep you properly insulated, mobile and neutrally buoyant as you probe into the depths of the ocean to inspect the bounties of marine ecosystems

Saving Coral Reefs
As responsible divers, our first priority is to protect the beautiful underwater world that we all so deeply love. With just a little care, coral reefs and fish can easily be left unscathed. Here are some tips that might help SCUBA divers enjoy a safe and responsible trip into the deep blue;
Fins are a primary cause of coral reef damage. The use of short strokes for propulsion instead of heavy long strokes will cut down on the risk of damage through impact as well as greatly reduce turbulence, which can break off delicate pieces like fan and tubular coral.
Loose equipment can cause major damage to coral. One of the main problems, with wearing so much gear underwater, is that there are so many pieces that have to be monitored. Have a friend check all your equipment for loose or unattached parts before and after entering the water. Equipment can easily come loose with a high step entry or during underwater twists and turns, as might happen in wreck and cave diving.
Buoyancy control is one of the easiest ways to stay off of a reef. Novice divers and people that do not dive very frequently are especially vulnerable to the sharp tongue lashing of a Dive Master or Instructor for being unable to control buoyancy. The best advice is to relax, admit to the divers in charge that you are a little out of practice, and take your time testing your buoyancy before starting the actual dive. Remember, that your buoyancy can be refined from time to time during the dive; so do not simply get stabilized at the start of the dive then forget about it. Use your BC as a tool to help take the burden and stress off of using your arms and legs to move.
Underwater cameras offer great opportunities to record the incredible adventure of diving but also can be the source of two problems for the ocean environment. First, cameras can become underwater "hammers" if allowed to become loose and dangle while swimming. Make sure the camera is controlled throughout the dive to insure it does not hit the coral. Second, the flash will cause a fish to become temporarily blind, which can also cause it to become a meal for the next predator it stumbles upon. Be cognizant of the fact that you are directly creating a vulnerable situation for any fish you capture on film with a flash. My only recommendation for the use of a flash while shooting underwater is to not go around blazing away at everything you see; take a few pictures and only shoot when you think you have a photo that you would be proud of framing and placing on your wall at home.
I honestly think that divers all respect and cherish the ocean. With a little care, we can individually show our respect by lessening any damage to the coral reefs. Have fun and dive safe.

Why is the Coral Reef So Important?
Coral reefs all around the world are an extremely endangered habitat. The Maldives' coral is no exception. The coral reef is home to a plethora of marine life, including fish, conch, squid, octopus and algae.
Here many of these creatures find the food they depend upon for survival. The reef is also an important source of food and chemicals that are used for pharmaceutical purposes, such as cancer-treatment drugs and elements used in sunscreen.
All marine habitats are linked in some way, and they depend on each other to stay alive. The coral reef has a very important relationship with seaweeds and mangroves, another endangered aquatic habitat.
It's not just nature that depends on the coral. Many countries, including the Maldives, Australia and Belize, make a large portion of their annual income from tourism. The tourists visit to dive and snorkel around the coral reefs and learn about the incredible marine life that lives there.
Coral is extremely sensitive to climatic change and to human touch. Global warming is constantly threatening the wellbeing of the coral, and as the ocean's temperature rises, the coral is slowly dying. Sometimes you can see discolored coral on the reef; this can be a sign of global climate change. It's difficult for one person to make a change to global warming, but you can definitely avoid touching the coral reef. As soon as coral is touched, it will die. Unfortunately, many novice scuba divers touch the coral reef when they are learning, and as a result it dies. Lion's Head dive site in the Maldives was once completely damaged by divers who would sit on the coral while watching the sharks feed. Now, the site is a protected marine park, and the coral is slowly growing back.
The Maldives consists of 1190 coral reef islands, so life here is fully dependent on the survival of the reef. Several different types of coral are endemic to the Maldives, including stony coral, blue coral, horny coral and soft coral.

Scuba Diving in the Fiji Islands
The one thing that can mean all of the difference between an average scuba diving expedition and a breathtaking one is visibility, and there is no other place on earth that is as widely known for clear dives than the islands of Fiji. Located in the South Pacific Ocean, the Fiji Islands encompass an area just slightly smaller than that of New Jersey. The Fiji Islands are well known for soft coral, warm waters, and exceptional visibility.
One of the things that makes Fiji stand out from all other dive destinations is the Fiji archipelago which is encircled by a massive reef. Inside the reef, there are thousands of scuba diving sites that feature shallow lagoons; steep, vertical walls; and caves for exploration. Many of the sites are accessible right from the beach, while other sites can be reached by a short boat ride.
While Fiji is one of the most beautiful dive destinations in the world, it is the crystal clear waters surrounding the islands that make scuba diving in this region particularly enjoyable. Here it is not uncommon for visibility to hover at a consistent 200 feet during favorable weather conditions. Divers in the Southern Islands have even reported that they have been able to see clearly up to an amazing 500 feet on calm days.
Another characteristic of the Fiji Islands that keeps divers coming back year after year is that the waters surrounding the islands are remarkably warm year round. During the winter months (May to November) water temperatures of an average 77 degrees are ideal for scuba diving. In the summer, water temperatures average 86 degrees.
With scuba diving conditions like these, one might think that it's impossible to expect more from the awe-inspiring islands of Fiji. But the truth of the matter is that Fiji is home to one of the most advanced ecological systems in the world. Here you will find rain forests, mountains, and waterfalls above water, and an amazing variety of life under water.
There are more than 1,200 species of fish and 12 species of dolphin that call the Fiji Islands home. There is an abundance of colorful soft coral interspersed with hard corals of every variety; all of which can be seen during a scuba diving adventure at one of the top diving spots that can be found throughout the islands.
Some of the premiere scuba diving attractions of the Fiji Islands include the Great White Wall, the Pacific Harbor, the caves of Sawa-i-Lau, and Rainbow Reef. The Great White Wall is a breathtaking display of pristine white coral and the Pacific Harbor is a favorite feeding spot for hammerhead sharks.
The wide variety of scuba diving spots makes Fiji an ideal destination for divers of all experience levels. There are numerous shallow lagoons that are perfect for beginner divers as well as cavernous depths best explored by advanced divers. No matter what type of diving adventure that you desire, you can rest assured that Fiji can deliver.
