Prepare reef creation



COZUMEL, September.- 14 In the absence of reef systems for diving in the north of the island, the hotel's Cozumeleño dip is leading the project off its coast a total of 64 pieces of an amalgam of stone and steel which invest one million pesos for their manufacture to be held cozumeleñas hands or at least who live in the town.
entire burden of diving related activity is concentrated in the south coast of the island, generating daily hundreds to thousands of entry per day especially in the high season of tourism cruise or overnight call.
forced inclination This leaves no chance to the north coast, where the first hotels in the city were built and some of those who sell their product supply sea sand and sun, in which they can develop activities such as snorkeling but did not have many fish to admire, kayaks, or other, but not diving just for having no barrier reefs, but mostly spaces sand and further north abundant seagrasses.
theme of diving was a little out of place here, until the opportunity arose to dip on the coast of that hotel, which Francisco Camano, CEO of the company Qualti charge fabrication of structures, specifies that the immersion of the sculptures is due to a restoration project to release pressure on natural reefs in the south of the island, so that is another option for diving and avoid that natural reef systems are damaged.
A meter high, one meter wide and two meters long, weighing two tons, is part of the physical constitution of these 64 structures to be dipped into linear segments and not all strings of beads not to break the coastal dynamics such as currents and to avoid creating stagnant water on one side, with the intention of increasing marine biodiversity by the scarcity of fish in the area.
these trapezoids monoliths, be made ​​of concrete which was amended on PH surface, changing the acidity of the concrete in order that from day one start to have adherence to own a marina eight PH which is equivalent to a natural state, similar to what exists in the sea and having the proper salinity is that it must generate life from the moment of submerging, unlike what happens with normal concrete which PH has risen from about eleven to twelve.
trapezoidal These figures will have a steel frame and not having modified all the concrete PH resistance is not lost, only suffer change the outside, because of changed the whole PH Concrete lose strength, ie would hold a few years under water, but over a period of about 10 years with a stroke risk of crack and all work not only construction, but the bodies of colonization by flora and fauna is lost.
creating a chain of reefs that according to studies from the first week are colonized standing is intended for some fish and the first year arise algae and if there were corals in the area starts to become colonized with corals naturally.
fastening system of artificial reefs, would scuttle the floor with a bit of one to ¼ inch to a meter deep, to place six expansion plugs that get to the bottom would open making steady anchor and that would not be moved by strong waves and hurricane by the angles that have the parts, as it has many holes in its structure and two slopes that upon impact of the waves, the resulting force pushes the bottom of the stone, without lift, while the holes that cover, helps to dissipate the effect of suppressing the wave preventing the stone is high .
The University of Quintana Roo anchoring artificial reef flat appearance in Villablanca beach south of the island, the passage of a year and has covered enlamada and small fish and even be in area where there has been settled corals already has some coral individual.
It is not expected that this year the parts are installed in front of the hotel in the north, however it could be during the first half of 2015 to have permits from the Ministry of Environment and Natural Resources (SEMARNAT).
Each stone is individually setting the bedrock not be manipulating each artificial reef or moving it from side to side, or down to the seabed groups of parts to fix them that day or the next day but one by one, according to ordered by SEMARNAT, instance considered the anchor system as sustainable.
A time to be by drilling the seabed, particles bounce rock, will be absorbed by a suction cone sediment that will lead to a boat with everything and water, leaving dust deposited in a container and the water would go for another product and clean.
's anchors are covered with an alloy of materials for corrosion and will put a 'shirt' to each dip galvanized steel hot a degree, asking Petroleos Mexicanos (Pemex) as a requirement, and screws are made ​​of steel grade ten and 18.
entire product within the 64 pieces will be manufactured in Cozumel by local labor than they have You trained for each activity, since the creation of the reef structure, to attach them to the bedrock.
Along the coast north of the island, were sunk in 2006 two ships named "Laguna Mandinga" and "Laguna de Patzcuaro "eleven meters deep and 300 meters north of the beach Las Casitas, alternatively take the pressure ridge to reef south of the island, and until next year would be the second time you perform a work with similar goals but different parts and although the island is famous for its extensive system of natural reefs, already beginning to embrace the idea that there is also the option to artificially create spaces for generating biodiversity in parts of the coast where there is has natural rocks with flora, fish and corals.
