I'm not aware of any research project that's backed up at the moment.
Our science vessels, where we've had the greatest difficulty, are among the oldest in the fleet. In the past seven years there have been 90 surveys planned. Of those surveys, only two were not conducted because of issues with the vessels. However, a very significant number--33--were interrupted in some fashion because of breakdowns and were not conducted as originally planned.
So we have had significant issues, but for the most part we have been able to complete the surveys.
