We have many monitoring stations on the ground but this one is on the ocean to monitor water quality for Oil companies like the ones we have in India.

We all know that polystyrene (Plastic materials) is used extensively, practically non-biodegradable, toxic to marine and other life, and not really recyclable but just reused.

The stuff is used by companies such as Steelcase, Ford to name a few.
