GLOSS Station Handbook – Esperance

The GLOSS Station Handbook is currently being re-designed and upgraded.

Until a new version is available, the tide gauge station list below from the last version of the Handbook provides links to further details about each tide gauge in the GLOSS Core Network. Click column headings to sort the station list table. Click the GLOSS number buttons to view the station information.
