We call the gigantic pile of plastic stuck in the middle of the pacific ocean as the plastic vortex. As well as other marine pollutions, plastic pollution shows its serious impacts on the marine ecosystem, especially on its creatures. You might see the videos of a sea turtle having a plastic straw removed from its nose and of the seagulls' guts being filled with the small pieces of plastics.

This piece, Synthetic Ocean is composed inspired by these videos and several documentaries regarding plastic ocean pollution, such as A Plastic Ocean and The Mermaids' Tears: Oceans Of Plastic. As these documentaries are showing the microplastics have made the ocean toxic, and how those are consumed by the marine creatures, so threatens their lives, the pieces as well is depicting the positioned (polluted) ocean, and the dead organism as well as the plastic vortex made by human and the pacific ocean current together.

The composer depicts the soundscape through the symbolic sounds which the composer selected based on the contents of the piece to fit the big and small themes of the music and builds the structure of the piece along with the shape of the vortex.
