The lowest Arctic sea-ice extent in the satellite record

node

September extent falls to approximately 3.4 million square kilometres, the lowest of the satellite era and roughly half the average of the first decades of the record. The loss of thick multi-year ice matters more than the area figure: a thinner, younger, more mobile ice pack responds differently to a summer storm than the pack that preceded it, which is part of why a single season could go so far.

A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
