what's the worst damage expected from this? limited O2 exchange from surface cov'g? marshland pollution? prolonged foodchain disruption?
There are some problems with it contaminating the foodchain in the deep ocean but the shoreland and marshes will be ****ed forever. It's not like the rocky beaches in Alaska, wave action and human intervention can clean that up. I don't think you can't clean marsh and shallows. The marshes and shallows are also a very fervent and diverse habitat that isn't going to handle oil very well. The irony is that ancient marshes are where the oil came from. Sorry, the oil was put there by god on the seventh day.
