Deep Ocean Pathways and Climate Change in the North Atlantic

Explore the ocean's role in global climate through this insightful lecture by Susan Lozier at the 2001 AGU Spring Meeting. Delve into the mechanisms of deep ocean pathways, focusing on the North Atlantic basin due to its extensive data and diverse convective water masses. Examine how climate signals acquired at the sea surface are expressed in the ocean depths, and assess the ocean's effectiveness as a climatic reservoir. Analyze climatological property fields to understand the impact of recirculations and water masses on climate signal distribution. Investigate historical hydrographic data to identify patterns of climate change in the deep ocean over the past century, with particular attention to volume-averaged warming in the North Atlantic. Discuss the certainty of climate change identification on density surfaces spanning the deep North Atlantic. Consider the role of climate models in establishing the dynamical consistency of observed deep ocean climate signals. Note that while the video quality may be imperfect due to its age, the presentation offers valuable insights into ocean-climate interactions.
