LOPS Sea Level Workshop

LOPS Sea Level Workshop

LOPS Sea Level Workshop

The Sea Level Workshop aimed at discussing past, present and future sea level changes, from global to coastal scale, considering all possible data sources (in situ observations, remote sensing, numerical simulations). It will take place at Brest, from 1-3 June 2022, as an in-person meeting.

Note: Number of participants is limited: first-come, first registered.

Coastal areas are exposed to a large range of coastal hazards. Mean sea level rise will lead to flooding of the low-elevation coastal zones. Tropical cyclones or extra-tropical storms generate storm surges, causing devastating coastal flooding. For example, in 1970, Bhola cyclone hit Bangladesh coasts, killing 300 000 people, whereas in 2004, Hurricane Katrina hit severely the U.S. Louisiane and Mississipi coasts, killing 1 200 people. At the same time, the coastal areas are more and more densely populated. The number of people living in the low-elevation coastal zones could double between 2000 and 2060. In this context, it is essential to understand the sea level changes, in order to protect our coasts in the future.

Objectives of the workshop

The ‘Sea Level workshop’ aims at discussing past, present and future sea level changes and its contributors, at global and regional/coastal scale, from all possible data sources (in situ observations, remote sensing, coupled/forced global/regional numerical simulations). The workshop will allow to present new results on sea level changes and to promote collaborations among national actors (labs and companies). The workshop will focus on all the processes that contribute to sea level from subannual (high frequency processes such as tide, internal tide, storm surges, waves, infragravity waves, meteotsunamis, seiches, tsunamis…) to multi decadal changes (such as ocean heat content and freshwater content changes, freshwater imports from land, ocean circulation/transport, air sea interactions, etc…). Studies focusing on identifying and quantifying uncertainty in sea level change and its components are welcomed. The workshop will also welcome studies relative to innovative methods, allowing to detect changes in long-term time series.

ECFAS’ Maialen Irazoqui, Mercator Ocean International, provided a presentation during the conference:

The workshop is organized by LOPS (Ifremer, CNRS, UBO, IRD). The workshop will benefit from the support of ISblue, LEFE-GMMC, ANR ClimEx.

Date: 1-3 June 2022

Location: Brest, France
