GLOSS Implementation Plan 2012
The GLOSS Implementation Plans provide background information on the programme. The first proposals for GLOSS were developed during the mid-1980's by an IOC Task Team of interested scientists led by Dr.David Pugh and Prof. Klaus Wyrtki. This resulted in the First GLOSS Implementation Plan:
IOC. 1990. Global Sea Level Observing System (GLOSS) implementation plan. Intergovernmental Oceanographic Commission, Technical Series, No. 35, 90pp.
The first GLOSS Implementation Plan (GIP) established the GLOSS Core Network (GCN) of ~300 tide gauges distributed around the world, technical standards for GLOSS tide gauge stations, as well as the basic terms and obligations for Member States participating in GLOSS.
In 1997, the requirements for GLOSS, in particular with regard to the interactions with new technologies such as satellite radar altimetry, the Global Positioning System and absolute gravity, were re-assessed in the GLOSS Implementation Plan 1997 which was presented for approval to the IOC Assembly in July 1997. This Plan also outlined updated mechanisms for global tide gauge data flow in order to make sea level data more accessible to the community. The full reference of the plan is:
IOC. 1997. Global Sea Level Observing System (GLOSS) implementation plan -1997. Intergovernmental Oceanographic Commission, Technical Series, No. 50, 91pp. & Annexes. (10.5 MB).
In 2012 the GIP was updated again. The focus of the GLOSS Implementation Plan 2012 remains the GCN and the datasets that result from this network. The new plan calls for two significant upgrades to the GCN motivated by scientific and operational requirements: (i) report of data from all GCN stations in near-real time; and (ii) continuous global navigation satellite system (GNSS) measurements in the vicinity of the tide gauge benchmark (TGBM) for all GCN stations.

A list of publications relevant to GLOSS and to the PSMSL is available.
A two page brochure in Adobe Acrobat format produced for GLOSS for the International Year of the Ocean (1998) can be obtained in various languages from the PSMSL Sea Level Brochures page.
GLOSS had a newsletter on the web called the GLOSS Bulletin with articles in English. However, at the GLOSS Experts Meeting in April 2001 the decision was taken not to produce the Bulletin again until further notice.
The Afro-America GLOSS News remains published on paper and on the web by the University of Sao Paulo, Brazil with most articles in Spanish or Portuguese (email firstname.lastname@example.org for further information).
