Tourism to the northern part of the island exists during four months (November to February). The most densely populated part is Junior. There is scarcity of sweet water on the island. Only a few ponds and a number of tubeless supply sweet water for drinking as well as for cultivation. Though the island falls in the monsoon zone, the climate is much influenced by the sea. The main vegetation is coconut, betel nut and bamboo. Coconut trees are abundant and more concentrated in the Junior area. The soil of the island is not so fertile.
The main agricultural products are onion, watermelon and some rice. Last 5 years SST. Martin’s visitor population has increased dramatically. While this situation has proven to be lucrative for the islanders, it is causing the natural beauty of the island to deteriorate. Presently there are many efforts being put forth to preserve the several endangered species of turtles that nest on the island, as well as the corals, some of which are found only on Mariner Jenifer. Pieces of the coral reef are being removed in order to be sold to tourists.
Nesting turtles are sometimes taken for food, and their hatchings are often distracted by the twinkling lights along the beach. Species of fish, a few Just recently discovered, are being overfilled. Every year the fishermen must venture further out to sea to get their catch. Most of them use motherless boats. At high tide the island is about 3 miles around, and pinched in the middle. The island exists only because of its coral base, so removal of that coral risks erosion of the beaches. SST. Martins has lost roughly 25% of its coral reef in the past 7 years.
The geological structure of the island is simple and is represented by an anticline uplift. A little of the axis of the anticline is traceable along the west coast of Disappears. The exposed portion of the axis runs NNW to SSE, approximately parallel to the island. There is a fault along the northwestern shoreline with a trend nearly parallel to the axis. SST Martin’s limestone is composed of mollusk’s coquina horizons (Shelley limestone) and coral clusters (coralline limestone). Being very porous and permeable, the Shelley limestone provides an excellent aquifer wherever they occur beneath the alluvium.
Recent marine sands and the Shelley limestone are the chief source of fresh water. Several living small coral colonies are found in small sheltered pools very near the low tide level around the island. They also occur in the surrounding shallow sea, mostly growing on the beach rocks and calcareous sandstone concretions. The dead coral colonies also occur in pool-like depressions within the high and low tide levels. Some of them are located at an elevation of nearly 3. Mom above the low tide level. The oldest fossil coral belongs to Late Pleistocene, giving an age of 33,238 years (CO dating).
The clearest indication of the Holocene fulfillment of the island is the appearance of an emerged 3. Mm coquina limestone cliff on the coast of Disappears ranging in age from 450 years at the base to 292 years at the top (CO dating). The mean uplifting rate of the island, calculated from the above data, is 19. 0 mm/year. The location of the cliff is 1. Mm above the dead corals characterized by Pyrites SP, Corpora SP, Psychopaths SP, and Planetary SP provide evidence of lower level emergence, ‘e, they have been raised above the level at which they are at present forming/living.
The radiocarbon dates from emerged dead corals are recorded below the ultra low level liquid scintillation’s detection limit (ii O BP). This suggests that the dead corals have emerged fairly recently, indeed are still in the process of emerging. This means that the environment of SST Martin’s Island is now not favorable for the growth and development of the only coral island of the country that started forming at least since the last maximum glacial age (ca 40,000 years ago). * _ Beach of Saint Martin’s Landscape of Saint Martin’s Beach at north side of Saint Martin’s
