GLOSS Station Handbook – Norfolk Is.
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 the GLOSS number buttons to view the information. Click column headings to sort the table.
