Core SZ-4 · depth 1,842 m · −31.4 °C

Read the ice where it cleaves.

Floe is the console of the Sub-Zero Core Lab — every reading sits on a bright frosted pane, etched as depth strata, split by the one cleave-line that marks where the record changes.

Each core reads as etched strata, not a flat card.

Depth bands stack from young firn down to bedrock. The cleave marks the band where the climate record breaks.

Strata read

The cleave-line marks where the record changes.

One sharp diagonal crosses every reading. Above it, the ice is steady. Below, the chemistry breaks — and the warm spark flags the metre that needs a second hand.

  • Depth strata etched in fine hairlines, calibrated per metre.
  • One cleave-line per pane — never a forest of accent bars.
  • A single warm spark marks the one metre that flags an anomaly.

Bright, not dim

Cold light, read in full daylight.

The lab works in a glass cabin at altitude. The console is high-key on purpose — frosted white panes under cold blue light, so a reading is just as legible at noon on the col as it is in the dark of the core room.

  • Pure-white frosted surfaces, never a muddy grey wash.
  • Two cold accents plus one warm spark — used like highlighters.
  • Readouts in tracked mono, figures right-aligned to read fast.
