# Prudhoe Bay, Alaska

Prudhoe Bay /ˈpruːdoʊ/ is a census-designated place (CDP) located in North Slope Borough in the U.S. state of Alaska. As of the 2020 census, the population of the CDP was 1,310 people, down from 2,174 residents in the 2010 census, and up from just 5 residents in 2000; however, at any given time, several thousand transient workers support the Prudhoe Bay Oil Field. The airport, lodging and general store are located in Deadhorse, and the rigs and processing facilities are located on scattered gravel pads laid atop the tundra. It is only during winter that the surface is hard enough to support heavy equipment, and new construction happens at that time.
Overland access is by the Dalton Highway. As the bay itself is still 10 miles (16 km) further north through a security checkpoint, open water is not visible from the highway. A few tourists, arriving by bus or their own vehicles after a two-day ride up the Dalton Highway from Fairbanks, come to see the tundra, the Arctic Ocean and the midnight sun, staying in lodgings assembled from modular buildings. Tours must be arranged in advance to see the Arctic Ocean and the bay itself.
Prudhoe Bay was named in 1826 by British explorer Sir John Franklin after his classmate Captain Algernon Percy, Baron Prudhoe. Franklin traveled westerly along the coast from the mouth of the Mackenzie River in Canada almost to Point Barrow.

## Geography

Prudhoe Bay is located on the Sagavanirktok River.
According to the United States Census Bureau, the CDP has a total area of 558.0 sq mi (1,445 km$^2$) of which, 416.3 sq mi (1,078 km$^2$) is land and 141.8 sq mi (367 km$^2$) is water. The total area is 25.40% water.

## Climate

Prudhoe Bay, along with similar communities on the North Slope of Alaska, features a tundra climate (Köppen ET). Winters are long and frigid, and because the area is above the Arctic Circle, the sun does not rise during several weeks of each winter. Summers bring long daylight hours, with 24 hours of daylight during some summer weeks, but are still cool, being mostly between 45 and 55 °F (7 and 13 °C) and sometimes dropping to the freezing point.

## Health care

Prudhoe Bay is classified as an isolated town/sub-regional center. It is found in EMS Region 6A in the North Slope Region. Emergency services have limited highway, coastal and airport access. Emergency service is provided by a paid emergency medical services unit and Fairweather Deadhorse Medical Clinic. Auxiliary health care is provided by oil company medical staff and the Greater Prudhoe Bay Fire Dept. Individuals requiring hospital care are usually transported to the nearest hospital/medical center, Sammuel Simmonds Memorial Hospital, in Utqiaġvik. Because no roads connect Prudhoe Bay to Utqiaġvik, patients are transported by helicopter or air ambulance (a flight of approximately 45 minutes).
