Do NOT use jet ! Read these to know why:

"Does anyone have a better suggestion for a different colormap or something else?"
Firstly you need to know if your data are sequential or qualitative:
- sequential data means that the relative order of the data is significant. This incudes most physical phenonema, e.g. velocities, sizes, weights, etc. These are typically used in surface plots, etc., by setting the colormap.
- qualitative data are where the order is not significant, e.g. test subjects, etc.. Typically created via plot as separate lines, and the color is controlled by the axes line ColorOrder property.
Once you are certain if your data is sequential or quantitative, then selecting colormap is easy. A good place to start is by using Cynthia Brewer's colormaps, e.g. my FEX submission:
Or you can search on FEX for suitable colormaps:
You will even find some that are specifically designed for depths similar to what you describe, e.g.:
Not that to use FEX submissions they need to be downloaded and unzipped onto the MATLAB Search Path, or simply into the current directory.
