One bar per ice year, 15 February to 14 February. Fixed 0–366 axis.

Averaged over the 49 ocean cells within 100 km, this site carries sea ice for a median of 73 days a year, peaking at a median 70.6% concentration. The ice season here is shortening at -16.0 ± 11.0 days per decade, and that survives every gate this archive applies.

This site is the one the thinning kept here. 130 other known breeding sites lie within 200 km of it and were set aside with it, so this stretch of coast is counted once rather than 131 times — that is what being one of the 56 independent places means. It does not mean the site is alone. The 728 measurable sites in this archive thin to 56 places.

In the 2023 ice year — the last one this archive holds — the sea ice here lasted 21 days, which is this site's 4th shortest season of 41 and below its own median of 73. It was below the median at 657 of the 728 sites measured here and at 44 of the 56 independent places, which is the most widespread short season in the record: the whole archive is drawn in one frame.

Two limits. This is the sea around the site and never the fast ice on it — at 25 km that is invisible. And the archive ends 2024-12-31, so it is a climate record rather than a current reading.

Why there is no count on this page

Penguins are too small to resolve from orbit. What is visible is the guano stain a colony leaves on the ice, which is why counting from satellite is a colour problem rather than a counting problem — and it is not solved. Our own detector correlates at r = −0.16 against ground counts across eight colonies, which is no relationship at all. Until that is fixed, this site publishes locations and says nothing about numbers. A number we cannot defend would be worse than none.
