[Termes IGN] température de surface de la merRésumé : (auteur) This study aims at commenting the article by Romano and Lugrezi (2007). Four main facts are brought to light: the temperature data used by Romano and Lugrezi were not sea temperatures, but air temperatures measured inside the Marseille tide gauge building; the sea temperature data still exist and were already exploited in at least three studies; these sea temperature data were never used to correct the tide gauge recordings for any effect in the computation of mean sea levels; the sea temperature was not measured in the tide gauge well, but outside of the building.

[Termes IGN] niveau de la merRésumé : (auteur) The results from a carefully implemented GPS analysis, using a strategy adapted to determine accurate vertical station velocities, are presented. The stochastic properties of our globally distributed GPS position time series were inferred, allowing the computation of reliable velocity uncertainties. Most uncertainties were several times smaller than the 1–3 mm/yr global sea level change, and hence the vertical velocities could be applied to correct the long tide gauge records for land motion. The sea level trends obtained in the ITRF2005 reference frame are more consistent than in the ITRF2000 or corrected for Glacial‐Isostatic Adjustment (GIA) model predictions, both on the global and the regional scale, leading to a reconciled global rate of geocentric sea level rise of 1.61 ± 0.19mm/yr over the past century in good agreement with the most recent estimates.

[Vedettes matières IGN] AltimétrieRésumé : (Auteur) The issue of a possible tide gauge datum discontinuity at Brest, caused by the bombing of the city in August 1944, is discussed. This issue is very important, as many scientists have used this long record to derive a long-term sea level trend estimate for use within global sea level rise studies. A detailed analysis of historical leveling information, and comparison of sea level data between adjacent stations, proved to be worthwhile, even beyond this initial scope of the study: it led to an accurate datum connection between recently rediscovered 18th century sea level data (back to 1711) and those of the present day. The study provides additional evidence that the onset of recent rapid sea level rise most likely took place in the late 19th century, in agreement with the nearby Liverpool sea-level record and with independent results from sediment cores collected in salt marshes located in both hemispheres.

[Termes IGN] verticaleRésumé : (auteur) Monitoring vertical land motion at tide gauges is mandatory if absolute or climate related signals in mean sea level are to be derived from coastal tide gauge records. Different glacial isostatic adjustment models provide very different predictions at the required level of a few tenth of millimetres per year accuracy, while other processes that may affect the vertical stability of tide gauges are still more difficult to predict. An alternative approach is to measure the rates of vertical land motions at the tide gauges. Continuous GPS recordings are presently the most practical and accurate technical solution to address such an issue. The most adequate way to handle the GPS processing seems to be a global scale approach in consistency with the size of the issues: geocentric reference frame realization, long-term stability, global climate change. The laboratories CLDG (Centre Littoral De Géophysique) and LAREG (Laboratoire de Recherches en Géodésie) contribute to the Tide Gauge Benchmark Monitoring (TIGA) IGS pilot project since October 2002 by routinely processing a global set of about 140 GPS sites within the ULR analysis centre consortium. The set comprises about 122 TG-CGPS stations that are analysed using a free network approach. Time series of more than six years are now available. The accuracy of the vertical component is very sensitive to the reference frame definition and realization. We therefore performed some tests in order to quantify the impact of various analysis options on the stability of our realization. We compared the stability of our global solutions with respect to ITRF2000 solution and to its IGS realization called IGS00, while changing the number of reference stations and their geometry. The results indicate that the more reference stations are used the better the alignment to ITRF is performed. A large global distribution of the reference frame stations seems to mitigate individual station problems. The reference frame implementation is achieved within several millimetres accuracy on a weekly basis. The tests indicate that the choice of IGS00 or ITRF2000 datum was not a relevant issue to perform the alignment to ITRF at this level of accuracy.

[Termes IGN] montée du niveau de la merRésumé : (auteur) The problem of correcting the tide gauge records for the vertical land motion upon which the gauges are settled has only been partially solved. At best, the analyses so far have included model corrections for one of the many processes that can affect the land stability, namely the Glacial-Isostatic Adjustment (GIA). An alternative approach is to measure (rather than to model) the rates of vertical land motion at the tide gauges by means of space geodesy. A dedicated GPS processing strategy is implemented to correct the tide gauges records, and thus to obtain a GPS-corrected set of ‘absolute’ or geocentric sea-level trends. The results show a reduced dispersion of the estimated sea-level trends after application of the GPS corrections. They reveal that the reference frame implementation is now achieved within the millimetre accuracy on a weekly basis. Regardless of the application, whether local or global, we have shown that GPS data analysis has reached the maturity to provide useful information to separate land motion from oceanic processes recorded by the tide gauges or to correct these latter. For comparison purposes, we computed the global average of sea-level change according to Douglas [Douglas, B.C., 2001. Sea level change in the era of the recording tide gauge. Int. Geophys. Ser., 75, pp. 37–64.] rules, whose estimate is 1.84 ± 0.35 mm/yr after correction for the GIA effect [Peltier, W.R., 2001. Global glacial isostatic adjustment and modern instrumental records of relative sea level history. Int. Geophys. Ser., 75, pp. 65–95.]. We obtain a value of 1.31 ± 0.30 mm/yr, a value which appears to resolve the ‘sea level enigma’ [Munk, W., 2002. Twentieth century sea level: an enigma. Proc. Natl. Acad. Sci. U.S.A., 99(10), pp. 6550–6555].
