The Sea-level SIG provides a forum for sea-level science discussion in the UK.
Our interests encompass sea level studies at all time scales, from tsunami monitoring to paleo sea-level changes.This includes tides, storm surges, seiches, meteotsunamis. We’re interested in measurement and modelling to improve our understanding of the past and present changes in coastal sea levels, and to produce better predictions of future change and coastal flooding.

In July 2018 the Permanent Service for Mean Sea Level celebrated their 85th anniversary by hosting the Sea-Level Futures Conference in Liverpool, with sponsorship by the Challenger Society sea-level SIG. More than 100 delegates from 65 organisations around the world attended the meeting.
Participants discussed the current status of our knowledge of sea level science, covering key aspects of sea level change, and outlined the requirements for new and augmented research, technical development and observations to improve our understanding of global, regional and coastal sea level rise and variability. Special emphasis was given to current sea level observations, synthesis of available data and discussion of future novel observational techniques in coastal areas.
