Oxygen is critical to the health of the planet. It affects the cycles of carbon, nitrogen and other key elements, and is a fundamental requirement for marine life from the seashore to the greatest depths of the ocean. Nevertheless, deoxygenation is increasing in the coastal and open ocean. This is mainly the result of human activities that are increasing global temperatures (CO2-induced warming) and increasing loads of nutrients from agriculture, sewage, and industrial waste, including pollution stemming from power generation using fossil fuels and biomass.
The 53rd Liege colloquium will investigate new developments and insights related to deoxygenation in open and coastal waters. It is jointly organized with the Global Ocean Oxygen Network (GO2NE) and is a contribution to the Global Ocean Oxygen Decade (GOOD) program endorsed by IOC-UNESCO.
The following sessions are considered:
- Deoxygenation: understanding causes and attributing changes
- Assessing open ocean and coastal deoxygenation variability and trends
- Deoxygenation: observing and modelling
- Deoxygenation and ocean life
- Deoxygenation and co-stressors: understanding, monitoring and mitigating deoxygenation in the context of multiple stressors
- Ocean Deoxygenation - how the past can inform the future?
- Microbial Communities and their controls on biogeochemical feedbacks and interactions
- Deoxygenation, water quality and the climate system: understanding processes and feedbacks and developing actionable indicators
- Deoxygenation: ecosystem services, economic and societal consequences.
- Confronting deoxygenation and its impacts: translating science to management and policy
