Amtec has seal that costs about $5 / 100 m2, but we need twice that so it's about $100.000/km2, $400/acre, $0.009/sqft.
Breakwater
Acts as a breakwater, not sure how much this effect would be.

Biodegrading takes centuries, but according to Wikipedia Daniel Burd, a 16 year old Canadian discovered in May 2008 that Sphingomonas, a type of bacteria, can degrade over 40% of the weight of plastic bags in less than three months. "The applicability of this finding is still a matter for the future."
- Polypropylene can be recycled easily. Because it's one big plastic structure, it's probably easy to take it out the water, compress it and bring it to a recycling company.
