Five of the pups have been equipped with satellite transmitters that will provide the aquarium's Marine Mammal Rescue Centre with information about where the seals go and how they do after returning to the wild.
Veterinarian Martin Haulena says that information helps the team determine the ideal conditions for release and whether any changes need to be made to the rehabilitation program.
The satellite-linked tags are glued to the seal's hair coat on the animals' heads, and may last anywhere from a couple of weeks to a year.
Last year, the aquarium tracked five other rehabilitated seal pups and found that the animals dispersed widely from the area they were released.
Earlier this year, the aquarium released a rehabilitated adult porpoise with a satellite tag that fed information back to the team for 70 days.
