This study focuse. on tre.d e.timate. from 18 high-quality tide.gauge.stations along the.Me.ite.rane.n Se. coast. The.se.sonal Mann-Ke.dall te.t was run at a 5% significance.le.e. for e.ch of the.18 stations for the.pe.iod of 1993-2015 (sate.lite.altime.ry e.a). The.re.ults of this te.t indicate.that the.tre.ds for 17 stations we.e.statistically significant and showe. an incre.se.(no significant tre.d was obse.ve. only at one.station). The.rate. of se. le.e. change.for the.17 stations that e.hibit significant tre.ds, e.timate. using se.sonal Se.'s approach, range.afte. corre.tion for Ve.tical Land Motion (VLM) from 1.48 to 8.72 mm/a for the.pe.iod 1993-2015. Furthe.more. the.magnitude.of change.at the.location of e.ch tide.gauge.station was e.timate. using the.sate.lite.altime.ry me.sure.e.ts.
