The passengers, all off of the 62-person National Geographic Sea Bird, which departed June 2 from Juneau, were on a ship-sponsored shore excursion.
"We are deeply saddened by this tragedy," Lindblad Expeditions said in a statement. "Our thoughts are with the people involved in this accident and their families."
The deceased was a 66-year-old Sante Fe, New Mexico, resident. Six others, all family, survived the crash and were rescued by a Coast Guard helicopter. Of the survivors, one suffered a broken back and another a broken leg.
According to the Anchorage Daily News, the pilot of the plane suffered minor injuries.
