Marine DTM Source?

Does anyone have source for DTMs or data that is relatively dense for areas around L Jolla Shores and Catalina?

Specifically, Im looking for any access to products that I can use to create some better contour maps for SCUBA diving sites. As a land surveyor, I have the tools and software to produce some better charts than are currently available, such as Jakes Charts. Most of what is available are pretty weak in terms of decent contour data.

Id like to make some PDFs available for printout and lamination by divers to use for dives.

The reason this has come up is that a pleasure boat wreck that has been a fun dive for many years at La Jolla Shores, the Cabazon Cruiser, seems to have shifted of been buried by recent underwater geological events. Having better bottom maps that are currently available would be of tremendous value to sport divers.

Thanks in advance for any help you can supply!
