barrens. The movement of the glacial ice and rocks left scouring marks in the bedrock that are still visible. Peggy's Cove has been declared a preservation area to protect its rugged beauty. The Peggy's Cove Commission Act, passed in 1962, prohibits development in and around the surrounding village and restricts development within Peggy's Cove.

The ocean temperature ranges between 12 and 20° Celsius (54–68° Fahrenheit) in the summer and falls to between 0.5 and 4.5° Celsius (33–40° Fahrenheit) in the winter. The ocean moderates the air temperature over the land year round. The shape of the ocean floor and the numerous ocean currents facilitate a rich diversity of marine life along the Atlantic coastline. The Labrador Current flowing south from the Arctic cools the ocean during the summer months. Offshore, the Gulf Stream, travelling northwest from the Caribbean to the northern Europe warms the ocean waters. The confluence of currents off Nova Scotia brings unusual Arctic and tropical species to St. Margarets Bay. Marine life includes Atlantic bluefin tuna, white-sided and white-beaked dolphins, and pinnipeds. Endangered Atlantic leatherback sea turtles are seen in the waters near shore. Endangered right whales and many other species are found in the waters. Cultural impact The cove was the scene of a youth novel by Bryan Doyle called You Can Pick Me up at Peggy's Cove (1976), which was made into a film directed by Don McBrearty and into a video released by Beacon Films, Inc., in 1982. In 2016 it was announced that a Peggy's Cove–themed resort had opened in Thailand. William deGarthe Sculptor and painter William E. deGarthe lived in Peggy's Cove. A gallery exhibiting his work is open to the public between May 1 and October 31 each year. Outside the gallery, in the William E. deGarthe Provincial Park, is a carved granite outcropping. This 30 m (100 ft) sculpture was carved by deGarthe as "a lasting monument to Nova Scotian fishermen". It depicts 32 fishermen, their wives, and children enveloped by the wings of St Elmo, the patron saint of sailors, as well as the legendary Peggy.
