Oceanographic Data Visualized with MATLAB

File Information

The data is three velocity and density sections (A, D, and E) showing tidal flow over an underwater sill in a fjord. The colors represent landward velocity (towards the viewer); red with the tide, blue against. Three density contours are shown by black lines. The line at the bottom of the sill (Line E) shows two recirculations produced by the flow.


This file inspired Cmocean Perceptually Uniform Colormaps.

just a picture?

Hi there people - Nice picture, but I think Jody should consider delivering "the" toolbox or m code used; the data is available free of charge, ML Toolbox processed. Just try for it at for instance. Probably you will have to dig a little more for TOPEX tide data...

Well, it exists now! A picture without code is worth 1 star.

I did this all with Matlab, and standard toolboxes. You need to use multiple colormaps. After that there are four surfaces, three for the data and one for the topography. The topography had lighting turned on, the others surfaces did not.

The contouring took a bit of interpolation to adjust the x,y,z data of the contours to fall on the correct surfaces. But again, it was all matlab.

Sorry there is no source code. This was submitted before this repository existed, but the mathworks was requesting images. So I sent the image in w/o code. Wouldn't be very general code anyhow!

What is a .gif good for without any link to the software (be it commercial or free)?
