You need to search this forum, one of the "old-timers" did lots of work in the arctic and frequently shared his experiences.
But seeing how dirt is not an "effective ground path" I don't see why ice needs to be.

Lightning..MMMMM dry air, particulates (snow) blowing some of the situations where lightning can occur....Not sure. Frozen ground has an increase in resistance compared to similar soil not frozen.
BUt knowing that many of the installations are federal in nature I'd bet tons of money has been spent on research and installing ground electrodes.

Tom: An endorsement from you means a lot. I have not read either one of the papers you mention.
I wrote the standard for a ground plane in remote areas, that were impossible to make the earth an equi-potential medium. One project was in the silica sand of the Sahara Desert of Libya. The other was the coral reefs of the Marshall Islands, and the ice at Siple Station in the Antarctic.
We used the building and floor supports as the ground, just like an aircraft.
In the Antacrtic I was asked by one of the scientists "How are you going to get a ground on this 2 mile thick ice cap" I said " In the dirt we call it grounding, here I call it icing" I'm not sure how that went over. Some scientists have a weird sense of humor :grin:
