When a floating dock the size of a boxcar washed up on a sandy beach in Oregon, beachcombers got excited because it was the largest piece of debris from last year's tsunami in Japan to show up on the US west coast.
But scientists worried it represented a whole new way for invasive species of seaweed, crabs and other marine organisms to break the earth's natural barriers and further muck up the area's marine environments.
And more invasive species could be hitching rides on tsunami debris expected to arrive in the weeks and months to come.
"We know extinctions occur with invasions," said John Chapman, assistant professor of fisheries and invasive species specialist at Oregon State University's Hatfield Marine Science Center. "This is like arrows shot into the dark. Some of them could hit a mark."

Species die out, yes.
The biggest disaster in the history of mankind, and no news coverage of what is going on with Fukishima.
You would think that every nation which could afford it would be sending hordes of scientists and manpower to Japan.
Tepco and the Japanese government are still acting as if this is a problem they alone can handle.

The news is covered in some outlets around the world, but deemed geekish and boring old news in the USA.

(8,303 posts)The process is entirely natural. Granted, in the past there weren't docks and so forth, but the massive tree losses near the shore and all the near-shore debris always gets pulled out in these tsunamis.
Tsunamis and so forth are disruptive of natural processes, but the disruption is quite natural and has been a part of the ecosystem forever.
