Alaska is a state located in the Western United States on the northwest extremity of North America. A semi-exclave of the U.S., it borders the Canadian province of British Columbia and the Yukon territory to the east; it also shares a maritime border with the Russian Federation's Chukotka Autonomous Okrug to the west, just across the Bering Strait. To the north are the Chukchi and Beaufort seas of the Arctic Ocean, while the Pacific Ocean lies to the south and southwest.
The Tongass National Forest in Southeast Alaska is the largest U.S. National Forest at 16.7 million acres. Most of its area is temperate rain forest and is remote enough to be home to many species of endangered and rare flora and fauna. The Tongass, which is managed by the United States Forest Service, encompasses islands of the Alexander Archipelago, fjords and glaciers, and peaks of the Coast Mountains. An international border with Canada runs along the crest of the Boundary Ranges of the Coast Mountains. The forest is administered from Forest Service offices in Ketchikan. There are local ranger district offices located in Craig, Hoonah, Juneau, Ketchikan, Petersburg, Sitka, Thorne Bay, Wrangell, and Yakutat.
The Beaufort Sea is a marginal sea of the Arctic Ocean, located north of the Northwest Territories, the Yukon, and Alaska, and west of Canada's Arctic islands. The sea is named after Sir Francis Beaufort, a hydrographer. The Mackenzie River, the longest in Canada, empties into the Canadian part of the Beaufort Sea west of Tuktoyaktuk, which is one of the few permanent settlements on the sea's shores.
Chukchi Sea, sometimes referred to as the Chuuk Sea, Chukotsk Sea or the Sea of Chukotsk, is a marginal sea of the Arctic Ocean. It is bounded on the west by the Long Strait, off Wrangel Island, and in the east by Point Barrow, Alaska, beyond which lies the Beaufort Sea. The Bering Strait forms its southernmost limit and connects it to the Bering Sea and the Pacific Ocean. The principal port on the Chukchi Sea is Uelen in Russia. The International Date Line crosses the Chukchi Sea from northwest to southeast. It is displaced eastwards to avoid Wrangel Island as well as the Chukotka Autonomous Okrug on the Russian mainland.
Federal lands are lands in the United States owned by the federal government. Pursuant to the Property Clause of the United States Constitution, the Congress has the power to retain, buy, sell, and regulate federal lands, such as by limiting cattle grazing on them. These powers have been recognized in a long line of U.S. Supreme Court decisions.
The question of whether to drill for oil in the Arctic National Wildlife Refuge (ANWR) has been an ongoing political controversy in the United States since 1977. As of 2017, Republicans have attempted to allow drilling in ANWR almost fifty times, finally being successful with the passage of the Tax Cuts and Jobs Act of 2017.
The exploration of the Arctic for petroleum is considered to be quite technically challenging. However, recent technological developments, as well as relatively high oil prices, have allowed for exploration. As a result, the region has received significant interest from the petroleum industry.
Canada's early petroleum discoveries took place near population centres or along lines of penetration into the frontier.
The Chukchi Sea Shelf or Chukchi Shelf is the westernmost part of the continental shelf of the United States and the easternmost part of the continental shelf of Russia. Within this shelf, the 50-mile Chukchi Corridor acts as a passageway for one of the largest marine mammal migrations in the world.
The Leffingwell Camp Site, on Flaxman Island, 58 miles (93 km) west of Barter Island on the Arctic Coast of Alaska, was used by polar explorer and geologist Ernest de Koven Leffingwell on his pioneering Anglo-American Polar Expedition of 1906–1908, which aimed to explore the Beaufort Sea. The expedition's ship, the Duchess of Bedford, was allowed to become locked in ice which eventually destroyed it.
Ernest de Koven Leffingwell was an arctic explorer, geologist and Spanish–American War veteran.
Offshore oil and gas in the United States provides a large portion of the nation’s oil and gas supply. Large oil and gas reservoirs are found under the sea offshore from Louisiana, Texas, California, and Alaska. Environmental concerns have prevented or restricted offshore drilling in some areas, and the issue has been hotly debated at the local and national levels.
Offshore oil and gas in California provides a significant portion of the state's petroleum production. Offshore oil and gas has been a contentious issue for decades, first over the question of state versus federal ownership, but since 1969 mostly over questions of resource development versus environmental protection.
Offshore drilling for oil and gas on the Atlantic coast of the United States took place from 1947 to the early 1980s. Oil companies drilled five wells in Atlantic Florida state waters and 51 exploratory wells on federal leases on the outer continental shelf of the Atlantic coast. None of the wells were completed as producing wells. All the leases have now reverted to the government.
Offshore oil and gas in the Gulf of Mexico is a major source of oil and natural gas in the United States. The western and central Gulf of Mexico, which includes offshore Texas, Louisiana, Mississippi, and Alabama, is one of the major petroleum-producing areas of the United States. Oil production from US federal waters in the Gulf of Mexico reached an all-time annual high of 1.65 million barrels per day in 2017. Oil production is expected to continue the upward trend in 2018 and 2019, based on ten new oil fields which are planned to start production in those years. According to the Energy Information Administration, "Gulf of Mexico federal offshore oil production accounts for 15% of total U.S. crude oil production and federal offshore natural gas production in the Gulf accounts for 5% of total U.S. dry production."

A stamukha is a grounded accumulation of sea ice rubble that typically develops along the boundary between fast ice and the drifting pack ice, or becomes incorporated into the fast ice. It is a pressure ridge. Wind, currents and tides contribute to this phenomenon. Stamukhi tend to occur in belts that are parallel to the shoreline, along coastal shoals, at water depths of about 20 m (65 ft), but that can reach 50 m (160 ft). They can build up to heights 10 metres (33 ft) or more above the waterline. Although they remain pinned to the seabed, these features can be subject to small displacements, either due to thermal expansion or to the pressure exerted by the drifting pack ice onto the fast ice. Because stamukhi tend to be deeply grounded, they may occur as isolated ice features in the open sea during the summer season, after the surrounding ice has melted away.
The Southeast Alaska Conservation Council (SEACC) is a non-profit organization that focuses on protecting the lands and waters of Southeast Alaska. They promote conservation and advocate for sustainable natural resource management. SEACC is located in Alaska's capital, Juneau. The environmental organization focuses specifically on concerns in the Southeast region of Alaska, including: the Panhandle, the Tongass National Forest and the Inside Passage.
Campbell Lake is a lake in Anchorage, Alaska.
