Employability with a PhD?

Seeking advice! I've been working in academia for a few years and was accepted to two oceanography PhD programs to start this fall. I didn't study oceanography in college but I have a solid modeling/physics/chemistry research foundation so this is very exciting.

Before I commit to a grad program, I'd like to learn more about the employability of someone with a PhD in oceanography and what different career paths look like. My questions:

• Job titles other than professor or research scientist? • Employers or companies to work for? • Salary and work environment expectations? • Things I should do to prepare for any particular career field? • Would you choose oceanography again if you got to go back in time and start over?

I'm in the US, so I know the political climate is severely hurting the science job market and that things will get worse before they get better. Fortunately, both of my potential advisors have reassured me that their grants are secure. My (optimistic) hope is that by the time I finish grad school the tides will have changed and the job market will look better.
