Great blue hole

It was formed during several episodes of quaternary glaciation when sea levels were much lower. Great Blue Hole kallas ett blått hål i Belize barriärrev. Det cirkelrunda hålet är 1meter djupt och har en diameter på drygt 3meter. Det är avskärmat från det omgivande havet av korallrev. Preserved from the disturbance of time, and isolated in the darkness, the hole holds clues to a very natural part of our planet’s life cycle.

Hålet ligger mitt i ett korallrev och är över 3m brett och 1m djupt.

Am Ende der letzten Kaltzeit entstand es in den Kalksteinschichten und bildet einen Zugang zu einem unterirdischen Höhlensystem, welches durch den steigenden Meeresspiegel geflutet wurde. It is not only a world class destination for diving but also a rich habitat for a variety of marine life like nurse sharks, reef sharks, black tip sharks and even giant groupers. The Blue Hole of Belize. Se encuentra cerca del centro del arrecife Lighthouse, un pequeño atolón ubicado a 1kilómetros de la costa continental y la Ciudad de Belice.

But they also found the bodies of two divers who had been lost in the hole. An attraction centuries in the making. That’s because the Blue Hole is part of a larger reef system, which is also an UNESCO World Heritage Site.

Although the Blue Hole was charted by the Spanish, no one is sure what name they gave for the region.

Belize’s famous Blue Hole is incredible when viewed from above, but after an underwater expedition, we now know what lies at the very bottom. When you dive the Blue Hole in Dahab, you have taken on one of the most challenging environments in diving and you will experience something truly remarkable. This is why so many divers brave the meter wide hole , despite the fact that many divers have lost their lives here.

De meest gebruikelijke is om vanaf één van de vele duikscholen een dagtocht te boeken. When Jacques Cousteau puts a dive site on his Top Ten list, then you know it must be good. It lies near the center of Lighthouse Reef, a small atoll km (mi) from the mainland and Belize City. Branson hopes the find will raise awareness for protecting the ocean and reacting to climate change. Most blue holes are formed from sinkholes or caves that develop slowly over time, as rock begins to erode and collapse.

Many blue holes were formed during the last Ice Age, after sea levels rose and filled existing sinkholes with water. This meant the period of the Maya decline had likely been marked by a terrible drought. But what was at the bottom of the Blue Hole would mark a far more modern calamity. Today, at over 3metres wide (nearly 0feet), it remains a largely unexplored natural wonder.

I had not heard of any great number of accidents there. Hullet er 3meter i diameter og 1meter dypt. Det er del av Belize barriererev, som er oppført på UNESCOs verdensarvliste. Het ligt nabij het midden van het Lighthouse-rif, een klein atol voor de kust van het vasteland. Jest widoczna z kosmosu, a swoją popularność zyskała dzięki filmom telewizyjnym i prezentacjom wypraw morskich Jacques’a Cousteau.

A giant ocean sinkhole is located off the coast of Belize, near the centre of Lighthouse Reef, an atoll of km.

Belize’s Blue Hole is an instantly recognisable wonder of the natural world. It’s the world’s largest sinkhole and is located on the Mesoamerican Reef – the second largest barrier reef network in the world after Australia’s Great Barrier Reef. Richard Branson recently took part in the first submersible dive to the bottom.

I was able to make this dream come true thanks to Tropic Air, and it was even better than I imagined. Beneath the H2S layer, it’s very dark and due to a lack of oxygen, it makes it hard for creatures (and humans) to swim there. But it became part of the ocean millennia ago, then collapsed to make a spectacular sea hole some 5feet deep.

You would need a mini-sub to get all the way to the bottom!
