Actually, I believe that the excerpt says an "olive leaf", not branch, which is even more doubtful. For a leaf to form in a week after months of an olive tree being submerged (read: minimal sunlight if the olive tree was at the top of the highest peak local to the ark, say 3' under water) is another miracle.

Even more so when the water covering the earth had to be pretty salty, after all 2/3 of the earth is now covered with salt water, dilute it by 1/3 and use it to water a garden. Bad things will probably happen. But then again, I'm an idiot; I could't even find that boiling sea bit. Does boiling olive trees in salt water enhance leaf production?

Ah Hah! I know Someone that specializes in those...

Not necessarily a miracle. Don’t most plants return after drought, fire, and flood? The oceans were most likely not salty or only a little salty. In fact, the saltiness of the oceans is one of the natural clocks in support of 6,000 years since creation. The saltiest water is the water from the great deep - 6-10 miles below the Earth’s crust.
