O2 Conference 2018

The distribution of oxygen in the ocean is controlled by physical, biogeochemical and biological processes. Both the supply and consumption of oxygen are sensitive to climate change in ways that are not fully understood.
Recent observations suggest that the oxygen content of the ocean is declining (ocean deoxygenation) and that oxygen minimum zones and coastal hypoxia sites are expanding with tremendous effects on the ocean’s ecosystems and living organisms.

This conference will:

  • focus on the past, present and future state of oxygen in the ocean on global, regional and local scales 
  • analyse mechanisms and feedbacks critical to identify natural and anthropogenic causes of oxygen variability
  • determine impacts on biogeochemical cycles and ecosystems


Conference sessions will cover following topics:

  • Prediction & monitoring
  • Impacts on ecosystems
  • Impacts on fisheries/socioeconomics
  • Coastal systems
  • Major upwelling systems
  • Physiological effects & multiple stressors
  • Ventilation / oxygen supply
  • Oxygen consumption / microbiology
  • Paleo perspective
  • Biogeochemical feedbacks


The call for submission opens December 2017.
