Is there any indication of what happened after Ishmael made it back to shore?

I know he wrote the book, and it seems like he researched a bit for it (I think he mentioned talking to someone about cetology?). He makes a lot of extra commentary, but is any of it definitely related to his life after the Pequod?

I thought of this because I'm writing a paper about how the "call me Ishmael" line makes it sound like he named himself, and I was curious about whether he got more scholarly or religious after the Pequod, but now I'm wondering about his whole life.
