seeking chemical oceanography career advice!

Hi All! I am hoping for a bit of advice as someone who is considering applying for graduate school. I am deeply interested in pursuing research in chemical oceanography, and I am curious if anyone has any helpful experiences in a program like that or doing similar research. I graduated last year with a B.S. Chemistry and am working as a lab technician right now, but I completed an undergraduate research study about the salinity-temperature relationship in the atlantic ocean after taking a marine chemistry course while in school. It's a chemistry niche I discovered in my last two years of undergrad that I fell in love with, so I guess I'm hoping for some advice and/or direction to continue on this path. Right now I am checking out oceanography PhD programs to see if that's the direction I should go.
