Compiling this data from the whole continent allows us to study the source of the refuse and common trends. Recycling is still being ignored by many people. The ocean continues to be a dumping ground. It is only by organizing clean-ups such as these, bringing what lies below back, do we remind people, that the ocean does not end at the surface that we see. Seeing the look on the bystanders' faces as they realize just how much waste is coming up, is a true eye opener.
Most people have no idea how much garbage rests at the bottom of the ocean.
The method for using divers for a clean up is an interesting one. Each pair of divers use an onion bag with a rock inside, tied to piece of neoprene connected to a milk jug float. Once the bag is full the divers tug on the rope and a kayaker or inflateable comes over to pick up the bag and sends down a new bag. This reduces the need for the divers to bounce up and down, ruining their dive profile. This makes for a much safer method of collection.
