Hi, Robyn. At least if the oil lands here, we do have the population to get out and collect it. Like you, I'm also wondering if any proportion of the oil sinks. It looks almost solid, like a paste.

For non-Kiwis. NZ is a country the size of Britain, with a coastline longer than the USA (it twists a bit,) and a population half the number of New York City. Just over 4 million, half of us in Auckland.
If the slick blows onto the Coromandel Peninsula, there's no-one there to pick it up, and that is a rocky coast mostly, anyway. You'd never scrape it off.

Weather has improved, salvors are trying to get the rest of the oil off the ship. Beaches covered in Angus hamburger patties for your Big Mac, recyclable plastic, animal hides, timber, milk products. And oil. I wouldn't have believed that the sea could so thoroughly wreck shipping containers. Some are pulled to pieces. Tugs are collecting floating containers. The oil is going to a dump, so that our grandchildren will be able to enjoy it, too. Too polluted itself to salvage!
