A play on the term "sea" --- "long time no see" is something people say to each-other after they meet up for the first time in an extended period. But here, "sea"  transforms the meaning to mean: "it's been a long time since you've been in the ocean," which is an accurate comment for someone who has been paddling a boat through the desert for many miles.
