International and National Networks and Programmes

PSMSL

The Permanent Service for Mean Sea Level (PSMSL) is the global databank for monthly and annual mean sea levels containing data from almost 2000 sites. The PSMSL is a member of the Federation of Astronomical and Geophysical Data Analysis Services established by the International Council for Science (ICSU).

GLOSS

The Global Sea Level Observing System GLOSS is a programme of the Joint Technical Commission for Oceanography and Marine Meteorology (JCOMM) of the Intergovernmental Oceanographic Commission (IOC) and the World Meteorological Organisation (WMO) for the establishment of global and regional sea level networks. The main component of GLOSS is the 'Global Core Network' (GCN).

Information on each station in the GCN can be obtained from the GLOSS Handbook. GLOSS has newsletters on the web such as the Afro-America GLOSS News.

There is a web page for PSMSL and GLOSS related publications.

There is a special web page for GLOSS-Africa.

There is a special web page for GLOSS in South America.

Hawaii Sea Level Center

The Hawaii Sea Level Center based at the University of Hawaii operates the 'fast' GLOSS Sea Level Centre, and produces the Research Quality Data Set (RQDS) of Delayed Mode hourly sea level data.

CLIVAR (ex-WOCE) Sea Level Centres

The CLIVAR Sea Level Centres are operated at the University of Hawaii Sea Level Center and at the British Oceanographic Data Centre as `fast' and `delayed mode' sea level centres respectively for the Climate Variability and Predictability Programme. These functions evolved from the World Ocean Circulation Experiment (WOCE) Sea Level Centres at the two locations.

NTC Australia

The Australian National Tidal Centre of the Bureau of Meteorology holds extensive sea level datasets from Pacific, Indian and Southern Ocean sites and from the ASEAN region.

ACCLAIM

The ACCLAIM Programme is the Proudman Oceanographic Laboratory's sea level measurement programme in the South Atlantic and Southern Oceans.

ESEAS

One of the major results of the COST Action 40 "European Sea Level Observing System" (EOSS) is the vision to establish a European Sea Level Service, and the ESEAS project builds on this.

MEDGLOSS - Mediterranean and Black Seas

MedGLOSS is a sea level programme for the Mediterranean and Black Seas under the auspices of the CIESM and IOC.

NOOS - North Sea

The North West Shelf Operational Oceanographic System (NOOS) web pages contain near real-time sea levels for the North Sea area.

A similar near real-time display for the European Atlantic coast can be found in the Sea Levels along the European Atlantic Coast (SLEAC) web pages.

BOOS - Baltic Sea

The Baltic Operational Oceanographic System (BOOS) has established a real-time sea-level web page for Baltic countries.

IOC Sea Level Station Monitoring Facility

This site provides a monitoring service for real time sea level measuring stations that are part of IOC programmes: i.e., (i) the Global Sea Level Observing System Core Network and (ii) the networks under the regional tsunami warning systems in the Indian Ocean (IOTWS), North East Atlantic and Mediterranean (NEAMTWS), Pacific (PTWS) and the Caribbean (CARIBE-EWS). The site is developed and maintained for IOC by the Vlanders Marine Institute (VLIZ) in Oostende, Belgium.

ODINAFRICA

The Ocean Data and Information Network for Africa (ODINAFRICA) brings together marine institutions from twenty-five Member States of the IOC of UNESCO from Africa to improve the management of coastal and marine resources and the environment in participating countries.

Various Americas

South Pacific

South Pacific Sea Level and Climate Monitoring Project Project for which the sea level component is operated by the Australian National Tidal Centre

Southern Indian Ocean - ROSAME Network

The ROSAME network contains tide gauges from sites in the southern Indian Ocean. Its web site in English can be accessed by Clicking here and the version in French can be accessed by Clicking here.

The web site includes real time monitoring of the tide gauges which can be seen on the 'Data' pages of the sites.

GLOUP

The GLOUP (Global Undersea Pressure) is the global data bank for ocean bottom pressure measurements. This activity is an important contribution to the study of ocean circulation and tides, and was established formally as a sub-activity of the PSMSL in 1999. Pelagic Tidal constants are available under GLOUP.
