Our Universe scuba diving

Since the dawn of time, man has sought to understand his environment in order to better control it.

While we work in space and plan to go to Mars, we are still unable to go to the bottom of the ocean on our own planet.
It’s because we’re hungry for knowledge and experience that RALF TECH accompanies many adventurers, civilian or military, famous or unknown, in their quest for discovery, underwater or on water, at the antipodes
or closer to home.

The ocean is still our final frontier. In geography, an ocean is often defined as a vast expanse of salt water between two continents. In fact, it is more like a volume of water, constantly being stirred up by ocean currents. Approximately 70.8% of the Earth’s surface is covered by the World Ocean, commonly divided into five oceans – Pacific, Atlantic, Arctic, Southern and Indian – and several dozen seas. With an average depth of 3,682 metres, the oceans account for 96% of the biosphere’s volume.

The world’s oceans, which are home to the majority of living species on Earth (50 to 80% depending on estimates), generate more than 60% of the ecosystems that sustain us, starting with the production of most of the oxygen we breathe. It absorbs around 30% of the CO2 emissions generated by mankind. The world’s oceans regulate more than 80% of the Earth’s climate. It plays a major role in the Earth’s temperature.

It is therefore our source and our future. Scuba diving – whether professional or leisure – gives us a better understanding of the reality of our planet. Let’s explore the ocean to better appreciate it. Let’s get to know it better so that we can protect it more effectively.
