Why “eustasy” is a great word
A worldwide change in sea level caused by the alteration of ocean volume or capacity. Its name derives from a back-formation within English: from *eustatic* (borrowed from German *eustatische*, itself from Ancient Greek εὖ (eû, "well, good") + στάσις (stásis, "standing")) + the suffix *-y*. Unlike "isostasy," which describes the regional buoyant rebound of land after glacial unloading, or "relative sea-level change," which records the local, observable interplay of land and water, eustasy is the absolute, planetary metric—the ocean’s own volume expanding or its basin deepening. It is the slow return of meltwater from continental ice, the patient filling of abysses by spreading seafloor, and the imperceptible rise that redraws every coastline on Earth—a geological pulse too vast for any shore-dweller to feel, yet one that writes the future in submerged stone.
