- SOOP – Building an innovation platform for more ocean observation and technologies where new hardware and software will be used to collect oceanographic and climate-related data.
- Sailing for Oxygen – A citizen science project initiated to help marine researchers measure important information in the Kiel and thereby better understand the distribution of oxygen, temperature and salinity.
- TreX – The project investigates deep water inflow spreading rates and mixing in the Gulf of St. Lawrence, involving the release of an inert tracer (SF5CF3) in October 2021 and subsequent campaigns in 2022 to measure and examine tracer concentrations, alongside studying ventilation using anthropogenic tracers CFC-12 and SF6.
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.
