GLOSS Station Handbook

GLOSS Station Handbook – Naha

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.

Additional information
Other relevant informationThe TGBM is on top of the stilling well. Another benchmark is near the station which is used to decide the height of the TGBM and monitor the height of the tide station. This second benchmark is levelled in to the nearest first class benchmark which is part of the network operated by the Geographical Survey Institute, Ministry of Construction. Heights of benchmarks are described as above Tokyo Peil (TP).
