This series is a sequel to The Voyage of the Mimi, produced in 1984, in which the Granvilles rented their boat and services to zoologists studying the humpback whale in the waters off Massachusetts.
The series aired on PBS and was created by the Bank Street College of Education in 1988 to teach middle-schoolers about science and social studies.
In these second segments, one of the child actors (Ben Affleck or Carla Douglin) comes out of character and interviews real, in many cases well-known, scientists abouts their work.
These scientists include archeologists Bill Fash, Peter Reynolds and David Stuart, and rain forest ecologist Nalini Nadkarni.
In addition, Martha Hill, a silver medalist in the Winter Paralympics, comes out of character in an interview with Ben Affleck at the beginning of the information segment titled "Expedition 1 If I can Do This".
