Therefore to get a count you would need to count the transitions from under sealevel to sealevel or above.To get a count of what? I don't see that I really care how high above sea level an island is. Above sea level it is an island. Below sea level it is a reef. My plot example or submerged islands example assumes a comparison to whatever the "base" sea level is for the elevations. If you want to know the change between two non-zero sea levels, you call the function twice and subtract.
