Granted, 10 meters depth of plastic garbage would not be evident in a photo, but the surface area would help to put this in perspective for me. A picture speaks a thousand words, and I can see more people getting behind the project if they had a visual of this massive thing, and there's no aerial picture that I've been able to find.
I guess I can try this analogy. Imagine this scenario...and I repeat this is a hypathetical scenario...I dont want anyone thinking otherwise.
But, imagine reports of an growing insect infestation within middle of the Amazon Rain forest. Anyone who travels to the middle of the rainforest can find these tiny bugs all over the trees, and bring back samples and counts of how many bugs per tree they found. They can also sample in different spot areas to determine the range of the infestation.
However when they return, skeptics say "show me a picture of the insects over the whole area that is infected". The picture would only show lots of trees and no bugs because they are too small and camouflaged to see by air.
This is similar to what is happening with regard to the plastic problem.
When we sample the gyre regions, we skim the surface of the water with a device called a Manta Trawl ghost net. The opening (or mouth) of the trawl is about 3 ft across and catches all objects within the first 12 inches of the surface. All objects gathered by the mouth are then funneled into a fine mesh collection bag about the size of a small coffee can. We drag this net for set time periods (15 min, 30 min, 1hr).
The pictures seen with jars of clogged and cloudy water are the result of that collection process, so the contents of the jars are collected over a narrow, but long strip of the ocean. The primary analysis of these contents is comparing the quantity of inorganic plastic matter vs. natural lifeforms that should exist in the area. These collections over the last 10 yrs have shown beyond a shadow of a doubt that the concentration levels of plastic are increasing in the sampled areas.
If we wait until this problem is so bad that it is visible by a fly over aerial photo, then our ocean will be dead by then. And that doesn't even touch the problem of the polymers released into the ocean that are microscopic and cannot be collected with a net.
The ironic part of all this is, Humans will die in defense of their Gods existence, yet there are no pictures of God.
So why is it so difficult to get people to understand this problem when we actually have physical evidence supporting these claims. We just don't have pictures that show the whole thing because it is physically impossible to get such a photo.
So...for the record...coming from someone who has been there to see this first hand...there is no floating island, or floating mass that can be seen by air, but if you swim in the water out there, you will exit with tiny plastic bits stuck to your body and in your hair. And this will happen if you swim anywhere within the Gyre. And the Gyre is bigger than Texas.
