The Exlpoitation Of The Arctic Flashcards
What has led to significant industrial developments in the Arctic?
Oil and gas exploration
What American state has large reserves of oil and gas?
Alaska
When did drilling for oil in the Arctic begin?
In the early 1900s but this was in a piecemeal fashion
The discovery of the Prudhoe Bay oilfield saw oil exploitation take off in the Antarctic, when was this?
1967
Name two facts about Prudhoe Bay
- It is the largest oil field in North America
2. It has supplied 20% of America’s oil for the last 30 years
Why are the Prudhoe Bay oilfields so important to the USA politically?
Global oil prices are rising as well as energy insecurity
What was constructed between Prudhoe Bay and the ice free port of Valdez? (What’s in Valdez)
The trams-Alaskan pipeline (there’s a large oil refinery in Valdez)
Name the adaptations of the trans-Alaskan pipeline
- Built on insulated legs so the warmed oil wouldn’t melt the permafrost on the ground which would cause the pipeline to sink and break
- It is raised so it doesn’t interrupt the migration patterns of the Caribou
- It zig-zags to avoid breaking during earthquakes or by frost heave
Name some facts about the Exxon Valdez disaster
- March 1989
- Ran aground on the Bligh reef in prince William sound, Alaska
- It was travelling outside normal shipping lanes to avoid ice
- Spilled approx 10.9 million gallons of oil
- The oil slick created by this was over 1100 miles long
What do utilidors do?
They carry water heating and waste pipes to prevent permafrost melting
Why are buildings raised above the ground in the Arctic?
To prevent thermokarst (selective melting of permafrost)
What is Alberta, Canada being proposed to be used as?
A distribution centre for a gas line that will run there from northern Alaska
What are the issues with the proposed gas pipeline?
The buildings for the workforce and factories required to maintain gas flow, may adversely affect the environment, disturbing Caribou herds
What has increased as oil supplies in Prudhoe Bay begin to decline?
Pressure to develop alternative sites in the region
In 1923 what was established?
The National Petroleum Reserve Alaska NPRA
