A study of the longest tide gauge sea-level record in Greenland (Nuuk/Godthab, 1958–2002)
We study the longest tide gauge record available from Greenland, that is the Nuuk/Godthab site in southwest Greenland, for the time period 1958-2002. Standard regression methods and the application of the Ensemble Empirical Mode Decomposition technique reveal a rate of sea-level rise of ≈ 2 mm/yr, t...
