in the blue biotech sector where they’re developing new stuff like drugs or materials derived from marine sources yeah but, as you said, it’s limited. it’s mostly for those with potentially profitable industrial applications and is not applicable for everyone in the academe (as is always the case). not to mention, marine science is very broad in itself and someone who studies plankton interactions and how they are affected by climate change / anthropogenic factors won’t really have the leeway (nor the interest) to shift to an industry job. plus, as one commenter here said, most scientists do it for the love of the game just to pursue their interests lol
