possible career?

hi to all that see this<3 i’ve been thinking about going to school for oceanography, i am going to have an emphasis in biology for now i believe as i would have to transfer to a school that has oceanography as a degree so id probably do something to combine the two obviously and do biological oceanography. any pros and cons for any of those subtypes of oceanography? how does it impact day to day life if you know. i dont want to dedicate my entire life to just my career, i also like to have a family and my own hobbies and i’m not sure if thats something that isn’t super difficult to have. sorry if these sound stupid at all i am from a landlocked state and its very difficult to ask anyone that works in that sort of field. thank you<3
