I do remember the number now off the top of my head. Certainly with the polar, it has a capacity for approximately 100 personnel on board. In fact, the crew is only about half of that. That extra berth availability on board is meant for a variety of missions, whether it's for scientific or security missions or environmental response. It could be a whole range of missions. Certainly there is extra capacity on board to handle those types of missions.
