Here's a question I received some time ago from a reader of this blog who is in the process of writing a novel. I thought it'd be a nice way to pass our time while we wait for the latest PIOMAS update. My answer is basically the either/or image on the right, but maybe you come up with other ideas.
I am working on my first novel and want to check on the scientific validity of an idea: If an object were left on the ice near the North Pole how long could it conceivably remain frozen in the ice?
I know that the ice at the North Pole is different than land based ice. Whereas land based ice can reach thicknesses/depths of thousands of feet and exist for tens or hundreds of thousands of years, the ice at the North Pole is only two to three meters thick. I’m sure there is some melt or erosion on the bottom of the ice, and ocean currents keep the cap in constant motion moving ice from the center of the cap to the edge of the cap where it presumable melts or breaks off in the spring and summer. Both of these factors, and more I’m sure, affect the age of the ice at the North Pole.
So although my object could remain frozen in Greenland or Antarctica virtually forever there is a plausible time frame that it could remain frozen at the North Pole. My object would have been left on the ice circa 1800.
Thank you for any insight you can give.
