Healthy Oceans, healthy planet.

This is the theme for this years World Ocean Day

Why do we need a day dedicated to the Ocean? Well quite simply, marine ecosystems are being affected by climate change worldwide. Individuals and organizations across the planet are taking action for prevention of plastic pollution in our ocean. The marine environment around southern Africa is one of the most diverse, complex and variable anywhere in the world.

Let’s take a look a simple look at the oceanography of SA’s east and west coasts.

East - The oceanography of South Africa’s east coast and south coast are strongly influenced by the warm, fast flowing Agulhas Current. This is a well-defined western boundary current with origins in the Moçambique Channel.

West
- The West Coast is completely different, being dominated by the cold Benguela upwelling system one of the largest eastern boundary upwelling systems in the world. Primarily driven by the South Atlantic High Pressure (anticyclone) and associated south-easterly winds.

Pretty darn fascinating, and that is barely scratching the surface.

Now let us look at the role the ocean plays in our day to day lives:

• They generate most of the oxygen we breathe
• They help feed us
• They regulate our climate
• They clean the water we drink
• They offer a pharmacopeia of medicines
• They provide limitless inspiration!

As surfers and ocean users, we have a big responsibility to protect and conserve our playground. The ocean is not simply a large body of water; it’s a highly complex ecosystem.

theGREENERsurfer will be honoring the ocean and organizing a beach cleanup soon, because every day should be World Ocean Day!
