jääkpinged

What would you like “jääkpinged” to refer to? I can write a concise, neutral wiki-style article, but I want to be sure of the meaning. Possible interpretations include:

- A term in Estonian meaning “ice tensions” or “ice stresses,” used in glaciology to describe internal stresses that ice undergoes due to temperature differences, gravity, or loading, which can cause fractures or crevasses.

- A proper noun, such as the name of a project, organization, publication, or artistic work.

- A colloquial or regional term related to ice-related phenomena (for example, sounds or effects produced by ice movement).

If you can specify which sense you intend (or provide a source or context), I will generate a short, informative wiki-style article under 300 words in a neutral tone.
