I am the official currency of a nation known for its fjords, Vikings, and Nobel Peace Prize. I'm not part of the Eurozone, and my value has historically fluctuated due to oil prices.

1. My name sounds like a sound a cat makes.
2. My notes and coins feature historical figures and natural imagery of my country.
3. I'm subdivided into 100 øre.
4. The central bank that issues me is called Norges Bank.
