In the context of climate change and ocean warming, extreme temperatures are getting more frequent and more intense.

These anomalous warm water events are referred to as marine heatwaves and have dramatic consequences on marine ecosystems. Thanks to sustained ocean observations, these events can be identified, not only at the surface but also deeper in the ocean.

Key research questions include the spatial and vertical extent of these extremes, their causes (air-sea fluxes or ocean currents), impacts and how to predict them in the future. 


Particle image velocimetry of surface currents

Particle image velocimetry can estimate ocean currents from the observed sea-surface temperature. Find out more.

Observation impact assessment of future high-resolution observations...

Using a numerical model, this project investigates how data-streams improve model estimates.

Observation impact assessment using data assimilation

Measuring the impact of new high-res ocean observations is essential for observing infrastructure.
