Both the observed uplift and gravity rates at Ny-Ålesund<br />
are larger than that expected from the PGR effects.<br />
Our study indicates;<br />
(1) Relative sea level (RSL) changes:<br />
not major origin<br />
(2) Present-day ice melting (PDIM):<br />
If the recent ice melting rate increases, it can be<br />
a strong candidate to explain the difference between the t<br />
observed ed rates and the predicted ones.<br />
(3) Ambiguity of the computation of PGR effect:<br />
Computation is sensitive to both the ice mode and Earth’s<br />
structural parameters.<br />
At Ny-Ålesund<br />
lesund, the horizontal rates are useful to<br />
constrain the discussion of the vertical rate of the PGR.
