# Generate set of snow crab 10'x10' grids:
x <- expand.grid(seq(-66.5 + 1/12, -60 - 1/12, by  = 1/6),
                 seq(45.5-1/12, 49 + 1/12, by  = 1/6))
x$grid <- deg2grid(x[,1], x[,2])
x <- grid2deg(x$grid, vertices = TRUE) # Grid corner coordinates.
plot(c(-66.5, -60), c(45, 49), type = "n")
coast()
plot.grid(x$grid)
