OC002:
Advances in Modeling O2 and pH in the Ocean: From Physics to Fish


Session ID#: 27695

Session Description:
Trends of declining O2 and pH are frequently reported in the coastal and open ocean and are environmental concerns because of their deleterious effects on marine life and alterations of biogeochemical cycles. In the coastal zone, bottom water hypoxia and acidification are driven by land-based nutrient loads and physical processes such as stratification or upwelling. Acidification in the open ocean is driven by CO2 uptake and the carbon pump. Drivers of O2 declines in the open ocean are linked to large-scale changes in sea surface temperature, depth of the surface mixed layer, and upwelling. Due to the complex interactions of these physical and biological processes, which cannot be fully characterized through observations alone, numerical models are important research tools for quantifying mechanisms, assessing ecosystem impacts, and evaluating how anthropogenic activities may affect conditions. This session is devoted to the presentation of diverse modeling approaches, including those focused on describing the mechanisms controlling deoxygenation and acidification, on anthropogenic and climatic influences on these conditions, and on their ecological effects. We invite studies that predict the O2 and CO2 systems, including their effects, spanning topics from physics to fish. Applicable models range from fully empirical to complex three-dimensional models.
