Historical heritage

The rescue and digitisation of historical tide gauge data constitutes a further important source of sea level data, particularly since France has a wealth of stations and data (cf. annexe A of the thesis of N.Pouvreau) which is testimony to a past that cannot be revisited (to perform mesurements) but which is interesting to study in order to understand the fluctuations in sea level that occur today. (Follow this link to find out more about French tide gauge heritage and a precious digitisation tool: NUNIEAU). Here are a few examples of ongoing or previous work, illustrated by posters :
