Longest, and one of the most important of WW2.

5000 ships, and almost 1000 of them were tankers - Think of the POLLUTION!

Lest We Forget!

All that pollution and still no GW, eh?

Seamen were paid extra to sail on tankers , about $25.00 more a month , my Dad was a merchant seaman U.S. to the Empire 1942-1945 would not sail on tankers after he saw two go up in instant flames when hit by torpeadoes the crew never stood a chance .

It is a shame the merchant seamen did not get the same respect from the general public as did the military. Percentage wise, I believe they suffered more casualties than any branch of the military.

Microbes can eat all of that in a few months time period. The news media likes to point the finger at oil spills and side with the environmentalists on this issue.

But nature takes care of itself. (nature and microbes, that is)

[Sir John]

...and sunlight!

[boxcar]

Well the microbes thrive in a warm climate. Microbes may not have helped that Alaska spill very much. It is plants that require the sunlight.

[Sir John]

I am aware of photosynthesis and also UV rays.

I read a long piece on the Gulf of Mexico spill and the industry said that UV rays evaporate the light crude in about 3 to 5 days.

They compared that to the very heavy Alaska spill and said that it took a couple of years to begin breaking down, It is all gone now except the stuff under rocks.


If you can find an aerial pic of the Arizona you can see the fuel oil stream, and it disappears after a few 100 yards.

Plenty of info here.

The UV rays may evaporate a light film of oil in that time period. I was thinking more along the lines of a glob of crude on the surface. UV would not do much in that situation.

I picked up my facts from a petroleum engineer.

I had difficulty with your URL, but got this from Wikipedia:

Cleanup and recovery from an oil spill is difficult and depends upon many factors, including the type of oil spilled, the temperature of the water (affecting evaporation and biodegradation), and the types of shorelines and beaches involved.[1] Spills may take weeks, months or even years to clean up.[2]
---------------------
Elsewhere:

In the warm waters of the Gulf, oil degrades at a far faster pace than it does in colder conditions; the basic rule of thumb is that for every 10 degrees Celsius oil degrades at about twice the speed. Accordingly, the oil spilled by the Exxon Valdez in Alaska took much longer to break down than the oil in the Gulf of Mexico.

BP has come up with a hybrid oil that cleans itself up , but EPA won't let them use it until the nessasary paper work is completed a minimum of 10-20 years will be needed .

See, you train your guns and BP trains its oil.
