I really like the text and lines on the first example but not thrilled about the waves. Maybe using that technical drawing style with thin black line for the waves could work. The second logo is very striking kind of like a grumpy whale face. I like this font too but not sure it fits well with the thick outline of the design. Its great that you are helping out with this. The project sounds very interesting I'm going to read more about it. Thanks for the info!
