Ocean Observing and Tracers

Air-sea exchange at the surface plays a pivotal role in injecting crucial substances, such as oxygen and carbon, into the water, significantly influencing the chemical and biological milieu beneath the ocean's surface. Essential processes, namely ocean ventilation and circulation, function as dynamic mechanisms transporting surface waters into the ocean's interior and subsequently bringing them back to the surface. Through the observation of tracer compounds, we gain insights into the temporal scales and magnitudes of ventilation, facilitating a comprehensive understanding of processes vital for oceanic life, dynamics, and the broader implications for climate change.
