Professor Laure Resplandy is a biogeochemical oceanographer. Her research goals are to understand how climate and ocean physics influence marine biogeochemistry and ecosystems and how these changes can in turn impact the Earth climate. Prof. Resplandy's approach is to design and develop numerical models (from ocean regions to global climate system) and statistical tools to interpret in-situ and satellite observations.
Climate change and global carbon cycle.
Changes in ocean oxygenation, oxygen minimum zones and coastal hypoxia.
Influence of ocean physics on ecosystems and biogeochemical fluxes.
Climate modeling, ocean modeling from small-scale (1-100 km) to large-scale.

The loss of oxygen from the ocean due to warming is not ubiquitous. In the Atlantic Ocean there has been no oxygen loss or gain in the subtropics over the past six decades (top 1 km, see Figure). Hogikyan and co-authors show that the amplification of the hydrological cycle, a response to climate change that results in a ‘salty-get-saltier,…
The global ocean is losing oxygen with warming. Observations and Earth system model projections, however, suggest that this global ocean deoxygenation does not equate to a simple and systematic expansion of tropical oxygen minimum zones (OMZs).
