Examples

area   <- function(Amax, zmax, z){Amax * (1 - (z)/zmax)^2}
volume <- function(Amax, zmax, z){Amax * zmax/3 * (1 - z/zmax)^3}
zmax   <- 30                            # maximum depth (m)
Amax   <- 12.07 * 1000 * 1000           # total Area (m^2)
depth  <- seq(30, 0, -.1)               # depth (m)

hypso_cone <- data.frame(depth = depth,
  volume = volume(Amax, zmax, depth),
  area=area(Amax, zmax, depth)
)

## inverted  depth order
hypso_cone$level <- zmax - hypso_cone$depth
