The search for a 40-year-old woman who went overboard off the cruise ship Celebrity Solstice in Alaska is over. The U.S. Coast Guard has suspended the search efforts in Alaska’s Inside Passage on Tuesday after searching for the woman for about nine hours, Petty Officer Ali Blackburn said. USCG conducted a search by boat and a helicopter in the waters near Eldred Rock in Lynn Canal, 20 miles (30 kilometers) west of Juneau.

Celebrity Solstice captain reported the missing person at 3 a.m. Tuesday, the Coast Guard said. 

“Because of the searching that we've done, it has yielded negative results," Blackburn said. That, coupled with an estimated survival time of 6.19 hours in the water, led the Coasts Guard to suspend the search, she said.

The survival time was based on factors such as water and air temperatures and the person's age. The air temperature in Juneau was 51 degrees Fahrenheit (10.56 degrees Celsius) Tuesday afternoon, and the National Weather Service said the water temperature was 41 degrees Fahrenheit (5 degrees Celsius).
