Mason Froule, Australian marine biologist at his country's Oceanographic Laboratory Outpost on Macquarie Island, South Pacific, said the bizarre
accumulation is explained by a scientific term called "like aggregation"-- that is, the massing of similar objects over short or longer periods of
time due to wind or ocean currents, magnetic fields, buoyancy and other conditions.
"It's fairly common in the world's oceans," he said: natural events such as red tides, for example, are instances of "like aggregation." "People with
pets that shed lots of hair can see it in their own homes," Froule added. "The dog sheds everywhere in the room, but after falling out, the fur soon
collects in a few clumps and masses."

I'm not sold on this idea of "like aggregation". Are you?
Red tides don't occur because dinoflagellates are attracted to one another, forming a large mass. The mass is created when a threshold is reached and
they reproduce like mad, remove the oxygen, and the dying matter from other life around them provides them with nutrients to reproduce even faster.
It's a self sustaining cycle.
Fur balls are created because hair clings to hair physically like velcro. It also clings to rugs. In fact if you have hardwood floors you find more
furballs than on a rug.
If I release a small particles of the same size in a stream they should all settle out in the same general area. If the partlcles are larger they
would again all settle in the some area, but a different area. To me that's not aggregation. Aggregation is when one seeks out another.
I remember reading this book as a youngster of an area in the Atlantic east of the Canary Islands where all the currents converged upon an area
leaving huge fields of sargasso weeds. Old pirate ships would end up there for centuries with people who learned to subsist on various seaweed dishes.
There grew a community with members who visited one another with rowboats for social events. |
