Study Links Slower Renewal of Deep North Atlantic Waters to Climate Change

Study links slower renewal of deep North Atlantic waters to climate change

Berlin, Germany (SPX) Jan 20, 2026 The ocean constantly exchanges properties with the atmosphere when surface waters sink and carry oxygen, carbon and other tracers into the ocean interior. This ventilation process can be quantified using water age, a measure of how long it has been since a water mass was last in contact with the atmosphere. A new study from the GEOMAR Helmholtz Centre for Ocean Research Kiel now shows that the w

Ventilation of the North Atlantic is Weakening

January 20, 2026 / Kiel. The renewal of deep waters in the North Atlantic has slowed markedly over the past three decades. This is shown by a new study from the GEOMAR Helmholtz Centre for Ocean Research Kiel, now published in the scientific journal Nature Communications. The study demonstrates that the “age” of water masses […] The post Ventilation of the North Atlantic is Weakening appeared first on YubaNet.
