One of the great attractions of ice diving is the clearness of the water. The absence of waves and the lack of light that filters through the ice stops the growth of seaweed. Also, as these are almost untouched areas, they aren’t polluted by human activity.
The United States’ McMurdo Station in the Antarctic is considered to be the best place in the world to practise ice diving. You can only dive between September and February, as the rest of the year temperatures drop to -40ºC. Under the ice the water is the clearest in the world, offering a visibility of 300 metres.
The most ‘professional’ version of this discipline is practised in Greenland, Switzerland and Russia. These are the meccas for skilled divers. Diving among icebergs in Greenland, swimming alongside whales in the icy waters of the Russian White Sea, or entering the ice tunnels of Switzerland’s Lake Sassolo are not adventures to suit everyone’s lungs. In fact, in Greenland you are only allowed to go ice diving in the company of an instructor who acts as a guide and you must also hold a PADI OWA scuba diving certificate.
