April: Sea ice rapidly returns, ending expedition travel.
May: Fully inaccessible due to advancing winter ice.
June: Polar winter brings total darkness and extreme conditions.
July: Harsh winter environment with no access possible.
August: Continued ice coverage and complete inaccessibility.
September: Early spring, but still locked in ice.
October: Conditions begin to shift, though access remains closed.
