The Blue Move

If you’re an obsessive follower of earth porn then read on – You will be awed by these incredible images.

Travel has become a rite of passage. Some travel overseas and some travel below them.

Art is in the Sea

The Museo Atlantico is Spain’s new snorkelling and scuba diving site. The underwater art Museum opened as of February this year. The aquamarine beauty takes art to a whole new level.The installations are about 14m below the surface of the Atlantic Ocean – on the Coast of Lanzarote, west of Morocco

Imagine snorkeling through this artificial reef, shaped like people but microscopic organisms living abundantly on them. Sharks, turtles colorful fish all living in these reefs!

Artist Jason deCaires Taylor depicts a number of humanitarian scenes. The installations draw on a ‘dialogue between art and nature’. It is an artificial reef that attempts to shelter a number of marine organisms as well as highlighting the global crisis of our oceans. He has taken conservation art to the deep blue. tamcc-02-jason-decaires-taylor-sculpture

Lets take a dive deep under the water

When you take a breath to dive under the water an interesting phenomena occurs called the Mammalian Diving Response. As you dive deeper below the water’s surface your heart rate decreases. This is an attempt for the body to conserve oxygen. The blood in your body begins to flow from the ams and legs towards the vital organs.

As you dive further down the pressure increases. This is the sum of the all pressures, both the air and water above you. The further down you dive, the greater to pressure. With increasing pressure the body compresses air spaces in the body, the lungs and the ears particularly.

Up until 1949, scientists believed that pressure 30m underwater would kill a human. This was based on Boyle’s Law which explains a relationship between the volume of gas and pressure. Scientists believed that the lungs would collapse.

Italian air force lieutenant Raimondo Bucher transcended this belief  as he completed a free-dive to 30m depth on one breath.

Blood penetrates the cell walls of your organs to counteract the external pressure. At 91m the cells swell with blood and blood plasma to prevent them collapsing. This is a depth commonly reached by free-divers.
