Great Barrier Reef, Australia: life beneath the water’s surface.

When one sees beauty, one cannot but want to foresee its future.  But also when one contemplates that beauty, even from distance and considers what it takes for it to exist, one also must be stirred into realizing the importance of preserving it for the future.

The Great Barrier Reef faces many challenges.  Its marine parks were set up by those insightful people who saw what was happening in the region and knew that it was important to discourage abuse or misuse.   To erode the preservations is to add another challenge to global warming and mining interests that increase traffic and pollution in a sensitive area.

A large proportion of people do not venture beneath its surfaces to see what is there.  Those who do are enriched by the life forms who conduct their lives, unseen by the many,  but with the innate intelligence of interactions.

There are those who indulge in the ‘sport’ of  ‘fishing’.   It became popular to think of hooking a fish, jagging and tearing its mouth or internal system with the hook and then ‘letting it go’…..how one is supposed to eat with the injuries not contemplated.

There are so many species beneath the waves…….thanks to Mr. Tony Tubbenhauer’s photos when he was there some time ago, we can catch glimpses of the beauty of some of the undersea dwellers, all going about the business of the lives to which they were born.

Perhaps the closest some will come to the undersea beauty is this screensaver, a clown fish, or the character Nemo beloved of children in the movie.

The real living beauty of the Great Barrier Reef is all our responsibilities, to ensure that  the momentary convenience of monetary matters does not jeopardize the reality.  For the Great Barrier Reef is the inheritance of centuries.

Australia’s Great Barrier Reef – home to various species:

Over countless time, the Great Barrier Reef formed, steadily, delicately, generations of corals forming the environment for others.   Islands emerged and upon those islands, birds recuperate from flight, nest and raise their young.

A noddy tern sits devotedly on eggs.  As they use the large leaves of the pisonia trees, this creates a flat nest and in wild winds, the nest or chick are sometimes blown out.   On the tourist islands, those who care about them replace the chicks.  Noddy terns and others often fly very long distances in gathering food.

Rails often run about the islands.

Shearwaters scan the sea during the day for food, returning mostly at night.  On their incoming, they chatter in somewhat loud and mournful voicing, which led one person to ask if the place was inhabited by ghosts.

The Barrier Reef Islands, isolated refuges in the ocean, provide habitat for so many species.  Their existence, along with the great beauty of the world beneath the waves, luxuriant as they were with amazing corals and life, needs comprehensive protection.  The greatest need is for the recognition of the Reef and all its inhabitants in the uniqueness that takes centuries to form and the urgent addressing of issues to protect it.   The ‘Noah’s Ark’ that each island is of a part of history.

With thanks to Mr. Tony Tubbenhauer for the time that he spent diving the Great Barrier Reef and for his work on protecting the individual species by the establishments of the marine parks.

 

UNDERSEA GARDENS:

Individual Coral Reefs are formed by a wide variety of marine animals and plants. Coral forms by the slow accumulation and deposition of calcium carbonate (limestone) extracted from seawater.
The reef’s underlying framework is formed by stony corals and coralline red algae growing amidst the coral formations. The hard corals and coralline algae extract the materials from the seawater (shallow waters are rich in calcium and bicarbonate ions) and they combine them to form calcium carbonate or limestone.
Coral polyps use this to produce outer protective skeletons. With the passage of time their limestone skeletons form the coral reefs, which are built over decades and centuries.
Sponges and soft corals and other invertebrates assist the process as the corals grow and expand. Reefs can be atolls, barriers or fringing.
Most coral reefs are built from stony corals, consisting of polyps that cluster in groups. Polyps belong to the group which includes sea anemones and jellyfish. The corals secrete hard carbonate exoskeletons to support the coral polyps.

The Reef is home to many species.

The photos on these pages were taken by Mr. Tony Tubbenhauer and Mrs. Kath Tubbenhauer, during their dives over an extended period, when they both appreciated and recorded the great beauty that lies beneath the surface of the ocean.

The Reef  has taken countless millenia to produce the islands (built up by corals and the gradual accumulations of the growth upon many of them).  Immense respect for its systems are essential.

The islands provide nesting grounds for many species of birds.  The refuge of their natural harbours benefits the turtles who come to lay their eggs upon the shores.   The lagoons nurture the fish of so many species who reside there.

The Reef is also a fascinating adventure for tourists who appreciate its beauty.

Protections are always essential.   They become more necessary with climate change and also with other factors including the Crown of Thorns starfish which attacks the corals.

We have the greatest control over human custodianship – IF we are wise to more than the generation of moneys which will not compensate for the loss of this wonder of the world.

May we treat it wisely for it is irreplaceable.
