isopag
Very LowTechnical/Scientific
Definition
Meaning
A line on a map connecting points where sea ice is of the same age or where ice cover is present for an equal number of days per year.
In glaciology and climatology, a cartographic contour line indicating equal duration of ice cover or equal ice age; used to study ice dynamics and climate patterns.
Linguistics
Semantic Notes
Term derived from Greek roots 'iso-' (equal) and 'pagos' (frost/ice). Exclusively used in specialized fields like glaciology, oceanography, and climate science. Not used in general discourse.

Examples
By CEFR Level
- The map included an isopag indicating areas with 200 days of sea ice.
- By analyzing the shift of the 150-day isopag over decades, scientists quantified the reduction in Arctic ice cover.
- The paper used isopags to differentiate between regions of first-year ice and multi-year ice.
Learning
Memory Aids
Mnemonic
Think: ISO (equal) + PAG (as in 'pagophile', an organism that loves ice) = a line of equal ice.
Conceptual Metaphor
TIME AS SPACE (The duration of ice cover is represented as a line on a map).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'изопага' unless in a direct technical quote. Use descriptive phrases like 'линия равной продолжительности ледового покрова'.
- Do not confuse with more common 'iso-' terms like 'изотерма' (isotherm).
Common Mistakes
- Misspelling as 'isopage' or 'isopeg'.
- Confusing with 'isopleth' (a more general term for contour lines).
- Using in non-scientific contexts.

FAQ
Frequently Asked Questions
No, it is an extremely rare technical term used only in specific scientific disciplines like glaciology.
No, it would not be understood. Use descriptive phrases like 'a line showing where ice lasts the same number of days' instead.
An isopleth is a general term for any line on a map connecting points of equal value. An isopag is a specific type of isopleth for equal ice duration or age.
In British English: /ˈaɪsə(ʊ)paɡ/ (EYE-soh-pag). In American English: /ˈaɪsoʊˌpæɡ/ (EYE-soh-pag).
