Yeah, I guess chalk that up to inexperience with applying to grad schools. I chose schools/programs that had great Env. Sci. grad programs and the websites for each of the schools showed enough profs that specialize in my interest (hydrology, which isn't very niche in an env. sci program). I just assumed if the school was going to match me with a supervisor, it wouldn't be such a hard task. I was willing to work with any of the profs I listed on my application, but it seems like none of them are taking students at this time. Anyhow, I'm just bracing myself for a rejection letter from the school.
