Although Beebe continued to use Nonsuch Island as his base of operations throughout the 1930s, with the onset of World War II in 1939 it was announced that the ferry linking Bermuda to New York would soon be making its final run, requiring Beebe and his team to hastily abandon their station there. Transportation to and from Bermuda resumed in 1940, and Beebe returned there in May 1941, but the environment was slowly being transformed due to the war. A large number of military ships made docking difficult, most of the island's reefs were being destroyed to construct an airfield, and the combination of construction activity and pollution observed the sea life impossible. Appalled by the destruction, Beebe finally rented his station at Nonsuch Island to a military contractor and returned to New York.
