After reading through this thread here:
Debris removed from the Atlantic is not from the
airplane of Air France, says Aeronautics
I immediately thought of something many are not talking about.
Ocean Trash.
Is Ocean Trash interfering with the Down Air France investigation, possibly giving false hopes?
Here is important information for everyone to digest...
This is the largest known Gyre,
The Great Pacific Garbage Patch
The Great Pacific Garbage Patch, also described as the Eastern Garbage Patch or the Pacific Trash Vortex, is a gyre of marine litter in the
central North Pacific Ocean located roughly between 135° to 155°W and 35° to 42°N estimated to be twice the size of Texas. The patch is
characterized by exceptionally high concentrations of suspended plastic and other debris that have been trapped by the currents of the North Pacific
Gyre. Despite its size and density, however, the patch is not visible from satellite photography.
TWICE the size of Texas.

Formation
Like other areas of concentrated marine debris in the world's oceans, the Eastern Garbage Patch has formed gradually over time as a result of marine
pollution gathered by the action of oceanic currents.
The garbage patch occupies a large and relatively stationary region of the North Pacific Ocean bound by the North Pacific Gyre (a remote area commonly
referred to as the horse latitudes). The rotational pattern created by the North Pacific Gyre draws in waste material from across the North Pacific
Ocean, including the coastal waters off North America and Japan. As material is captured in the currents, wind-driven surface currents gradually move
floating debris toward the center, trapping it in the region.
The size of the affected region is unknown, but estimates range from 700,000 km² to more than 15 million km², (0.41% to 8.1% of the size of the
Pacific Ocean). The area may contain over 100 million tons of debris. It has also been suggested that the patch may represent two areas of debris that
are linked.
Sources of pollutants
It has been estimated that 80% of the garbage comes from land-based sources, and 20% from ships at sea. Currents carry debris from the west coast of
North America to the gyre in about five years, and debris from the east coast of Asia in a year or less. An international project led by Dr. Hideshige
Takada of Tokyo University studying plastic pellets from beaches around the world may provide further clues about the origins of pelagic plastic,
including that of the Pacific garbage patch.

As you can see in the above picture there are other places where trash accumulates and stays in the ocean.
To put this into perspective here is something to visualize:
The average Trash dump is a few acres. Tucked away on the out skirts of any city. Sometimes even in the city itself.
Now take that few acres of trash, dump it into the ocean and let it drift in the currents for awhile. It'll meet up with other trash and form a
lovely floating island of non biodegradable mush.
Now take the state of Texas, dump it into the ocean and let it float around turning into mush... That is how much trash we are talking about. Two
states of Texas floating around the Pacific Ocean.
Remember that's only the pacific trash gyre...
