Low lying banks of Black Hole contained black, uninviting water. Most likely this was the first time when humans reached this weird lake. Group was led by the experienced cave diver, lawyer, and geomicrobiologist Stephanie Schwabe.
#Black hole in ocean movie#
In late June 1999 the most impressive black hole – the Black Hole of South Andros – was reached by a team of scientists and movie makers. Location of most black holes is not popularised – these unique monuments of nature easily could be endangered by random visitors, especially – by diving. All of them except for one, are located on the largest island – Andros, especially in the south-western and central part. In total there are more than 30 black holes in the Bahamas. Most likely they are not linked to the sea and they do not have lateral passages. Thus, contrary to many sinkholes around the world, black holes have not formed from deeper layers to the top, but in the opposite direction – from the surface downwards. Sea level though has changed often – local mudflats over the last 1.8 million years some 30 times have experienced ascent and descent of sea.Īt some locations the aggressive seawater started to dissolve the carbonate rock at the base of poodles, gradually forming round, rather deep holes. Most likely similar conditions have lasted here for a long time. Low lying mudflats have numerous inundated areas with shallow seawater and rainwater poodles, bays, and lakes. The layer of carbonate mud can be several meters deep, making these places unavailable by feet or boat. Today black holes are located in shallow, muddy flats. Light refraction here creates a crystal clear, beautiful blue color. More common here are blue holes – beautiful, diverse, deep caves filled with seawater and lined with bright white carbonate sand. Interaction between the porous carbonate rocks and seawater has created countless, extensive cave systems, most of them still to be discovered and explored. For some 200 million years, since Jurassic times here have accrued limestone, aragonite, dolomite, and gypsum layers with total thickness exceeding 6 kilometers. The Bahamas are the visible part of a giant "heap" of carbonate rock. Only then it was discovered that these round, black lakes are unique, unprecedented natural formations. Initially, these were considered to be meteorite craters.Īlthough this region is close to densely populated and affluent areas with numerous scientists and caving enthusiasts, only in late June 1999 there took place the first scientific expedition to the largest and most impressive of these holes – South Andros Black Hole. Only in 1985 from the airplanes in the South Andros Island there were noticed round holes filled with abnormally black water. This article draws attention to the fallacy of the black-hole syndrome, and to its potentially fatal consequences for the British claim to a 200-mile environment protection zone in the Chagos Archipelago.Phenomenon of black holes is a recent discovery and thus far they are known only in Andros and Grand Bahama islands in the Bahamas. The US and UK governments have evaded accountability by way of a persistent 'black hole' strategy, contending that some national laws and international treaties for the protection of human rights and the environment do not apply to the island-a position confirmed by a controversial appellate judgment of the House of Lords in October 2008, essentially relying on 'prerogative' colonial law. Environmental risks from US military construction on the atoll of Diego Garcia (British Indian Ocean Territory) since 1971 include damage caused by large-scale 'coral mining', the introduction of invasive alien plant species, continuous transits of nuclear material and unreported major fuel spills these risks are now compounded by those of sea-level rise and ocean acidification due to global climate change.
