Cruise ship companies have until Aug. 18 to apply to the National Park Service for the right to bring ships into Glacier Bay.
The companies compete every 10 years for the highly desired contracts that allow limited entry into the bay from June through August.
The upcoming contracts cover the period from 2010 to 2019.
No more than two cruise ships per day are allowed in the bay over the course of 153 days.
But those numbers can vary from year to year depending on the outcome of scientific studies on marine and other wildlife and of surveys on visitor experience.
