The Global Sea Level Observing System (GLOSS) 'Delayed-mode' Data Assembly Centre
The Global Sea Level Observing System (GLOSS) 'Delayed-mode' Data Assembly Centre at the British Oceanographic Data Centre (BODC) quality controls and archives high frequency (i.e. hourly or more frequent) global sea level data and any ancillary measurements (e.g. temperature, wind speed/direction, atmospheric pressure) that are included with the data. The tide gauges are situated on most coastlines, and data cover the Arctic to the Antarctic, and the Atlantic, Indian and Pacific oceans. The main component of GLOSS is the 'Global Core Network' (GCN) of 290 sea level stations around the world for long term climate change and oceanographic sea level monitoring. The Core Network is designed to provide an approximately evenly-distributed sampling. The GLOSS Long Term Trends (LTT) set of gauge sites (some, but not all, of which are in the GCN) are used for monitoring long term trends and accelerations in global sea level. The GLOSS altimeter calibration (ALT) set consists mostly of island stations, and provides a facility for mission intercalibrations. A GLOSS ocean circulation (OC) set, including in particular gauge pairs at straits and in polar area, complements altimetric coverage of the open deep ocean. Data exist from the mid 1800s up to the present day, with particularly long records from Newlyn, U.K.; Brest, France; Prince Rupert, Canada and Honolulu, San Diego and San Francisco, U.S.A.; Sea level has been measured by a variety of different instruments with the historical data mainly coming from mechanical float gauges. More recent technologies include acoustic, pressure, and radar instruments. GLOSS aims at the establishment of high quality global and regional sea level networks to create long‐term sea level records. These records, as well as being used in climate studies (sea level rise), are also used in oceanography (ocean currents, tides, surges), geodesy (national datum), geophysics and geology (coastal land movements) as well as various other disciplines. The programme became known as GLOSS as it provides data for deriving the 'Global Level of the Sea Surface'. GLOSS is an international programme conducted under the auspices of the Joint Technical Commission for Oceanography and Marine Meteorology (JCOMM) of the World Meteorological Organisation (WMO) and the Intergovernmental Oceanographic Commission (IOC). Data are collected by local agencies such as port authorities, universities and navies and sent to or downloaded by the data centre.

BODC protocols are based on the Open Archival Information System (OAIS) model enabling BODC to iterate towards compliance with the on-going evolution and development of community requirements including FAIR (Findable,Accessible,Interoperable,Reusable), TRUST (Transparency, Responsibility, User community, Sustainability, Technology) and CARE (Collective Benefit, Authority to Control, Responsibility, Ethics). Data managers quality assure submissions and assemble the metadata necessary for curation. Submissions (as received) are placed in a long-term accession and stored in triplicate across multiple sites. Appropriate data are transferred into a standard internal format with source variable names mapped to controlled vocabularies, documentation assembled, and metadata loaded into BODC databases. Access to these data is through direct request, the BODC website and through partner repositories such as SeaDataNet. Access control is attained by assigning a data policy to each set of data and this policy is used to administer access when data are requested. Discovery metadata is aligned with EU INSPIRE (through MEDIN) and SeaDataNet community standards. Data are converted to open community formats including Ocean Data View ASCII and SeaDataNet NetCDF, with data described using terms from the NERC vocabulary server. BODC submission agreements are documented on the BODC website and customer service is assured with a dedicated requests team that serve data following local regulations including General Data Protection Regulation (GDPR) 2018 and Environmental Information Regulations (EIR) 2004.
