Make bottom go woshh

Part of the problem here is that we have few values in the x-axis, and many in the y-axis. We sample points along the line you draw in the map while probing. Then, for every point along that line we fetch the sigma layers and bathymetry. Essentially creating unique depth profiles for every point sampled. As far as I understand, we then collect every points' depth profile into a large matrix. Creating extra y values at every other sampled point into all the other points (Each x-coordinate can get up to a thousand y-values).

Possible Solutions:

  • Restrict the contour plot to contain sample point x depth layers values
    • Just sample or find some smoothing/interpolation function?
  • Try filtering out y values
