Full marks for doing Marine Biology William,that I hope to swing over to soon my self.
Jealous of the diving bit.
Is the thick dust bits of old folks who have moved to Florida to die?I mean if you allow them into the ocean then all that old skin an stuff will scour off

Seriously I wish you well in your efforts to clean up the pollution,a problem that is world wide.Forget wind and other gimmicks,lets go nuke and use the money saved to clean up our oceans and rivers.
