Sea Level

Currently the installed tide gauge in our facilities AZTI,is a Paroscientific 8DP070-2. The tide gauge was installed in early Februay 2007 and is used, among othe scientifical purposes, to study the sea level variation. The Pasaia station is of utermost importance, since it is complemented with a Permanent GNSS Station (with a double GNSS receiver) and the National Levelling Network is only some 250 m away. This is why Pasaia plays a lead role in the Datum definition for Gipuzkoa.

Originally, the electronic device that retrieved the raw data from the tide gauge had the following specifications:

In February 2009, the electronic device crashed, and was replaced by a datalogger-based system. The datalogger selected was Campbell's CR800.
