• Résultats des mesures de contrôle
  3 avril 2008, par Guy Woppelmann

  Les résultats des mesures de contrôles ’in situ’ sont directement intégrés dans les pages correspondants au marégraphe concerné. Les missions de contrôle font généralement l’objet d’un rapport dans lequel figure le résultat de l’exploitation des mesures d’étalonnage (diagramme de Van de Casteele). Voici un exemple : contrôle du marégraphe de Socoa (Saint Jean-de-Luz) en mai 2007.

  – Vertical velocities table
  The JPL14_Vertical-Velocities_Table provides the vertical GPS velocities and uncertainties from the 436 stations fulfilling the criteria of 3 years of minimum length and data gaps not exceeding 30%, estimated by the JPL group.
  – Daily time series
  The JPL14.zip file contains individual station data files of daily position time series in ITRF2014 with respect to the position at the epoch 2023-01-01. These positions are expressed in meters in the local frame (…)

  The web map enables the users to navigate from one site (station) to another, and click on a specific site in the map to see its attributes. By clicking further, an individual web page for the site can be accessed, where details on the data and meta-data are displayed for that site. The user can then get some additional statistics and download files with the associated time series (sea level differences...). Here, we provide a more comprehensive means to download the data from all the sites. (…)

• The historical French heritage
  14 December 2010, by Frank

  France is very rich in systematic observations of coastal sea level over long time periods. The oldest (published) series of measurements were performed by the astronomers La Hire and Picard at Brest, France, in 1679, over about ten days. They repeated the experiment in 1692, over several months, again in Brest. Their aim was to study the tides and their results showed the fundamental importance of observation to understand and determine the characteristics of tides in a given place for the (…)
