55th International Liège Colloquium on Ocean Dynamics

  • The GeoHydrodynamics and Environment Research group (GHER) of the university of Liège in Belgium is organising its 55th international colloquium on ocean dynamics from 27 to 31 may 2024.

In the center of the picture, someone stands feet in the seawater covering the square. He/she turns the back to the photographer while presumably taking a photo of the Laguna.
  • This year's colloquium will focus on Ocean Extremes

  • Marine extreme events, encompassing phenomena such as storm surges, marine heatwaves, harmful algal blooms, jellyfish blooms, extreme storms, and even unique occurrences like Medicanes (Mediterranean hurricanes), are becoming more common in our changing world. These events have profound consequences for marine ecosystems, coastal communities, and global economies. Extreme sea level events, driven by intense storms and rising sea levels, can inundate coastlines, leading to devastating flooding and erosion. Marine heatwaves, fueled by climate change, can trigger mass coral bleaching events, disrupting delicate marine ecosystems and jeopardizing the biodiversity they support. Harmful algal blooms and jellyfish blooms, exacerbated by nutrient pollution and warmer waters, can lead to oxygen depletion, cause mass mortality events in various species, and pose risks to human health.

  • The 55th edition of the International Liège Colloquium will focus on Ocean Extremes. Five sessions are planned :

    • Drivers and mechanisms (air-sea interactions, ocean processes, local and remote drivers... )

    • Long-term changes (paleoclimate, historical reanalyses, future projections, detection and attribution, interactions with climate modes, extremes at high latitudes, long term observations)

    • Compound events (preconditioned, multivariate events, temporally compounding and spatially compounding, cascading events)

    • Predictions (novel forecasting approaches, numerical modeling and machine learning, operational systems, applications and technologies, adequacy of observations and monitoring)

    • Impacts and Adaptation (short-term and long-term, coastal, individual and cumulative impacts on ecosystems, socio-economic impacts, adaptation, governance)

  • Ocean Extremes training session with EUMETSAT Copernicus marine data

    A hands-on session will be held on the use of satellite data for Ocean Extremes analyses. The OSI SAF team will take part in this workshop. More information on this will be posted here in due time. Every participant is welcome!
