Royal Commission on the Ancient and Historical Monuments of Wales (RCAHMW) 

The Royal Commission on the Ancient and Historical Monuments of Wales has a leading national role in developing and promoting understanding of the archaeological, built, and maritime heritage of Wales, as the originator, curator and supplier of authoritative information for individual, corporate and governmental decision makers, researchers, and the general public.

The landscape and built heritage of Wales result from people’s interaction with the natural world over thousands of years. Since it was established in 1908, the Royal Commission has led the way in researching and explaining the remains of that interaction – the archaeology and the historic buildings we see around us.

In addition to the extensive site database which comprises the national record of the historic environment in Wales and numbers over 119,000 entries, the Royal Commission holds a unique collection of photographs, maps, images, datasets and reports within its archive, The National Monuments Record of Wales (NMRW). Both the site database and archive contain records relating to the marine environment, including shipwrecks, submerged landscapes and coastal features; and the NMRW includes archives and datasets from maritime recording and archaeological survey.


The information held by RCAHMW is made freely available under the Government Non-commercial License, and can be accessed in multiple ways. Through Coflein, our online site database and catalogue, which allows users to search our site database and related catalogue of archive collections; via the People’s Collection Wales website and the Historic Wales Portal, which allow our records to be viewed alongside those of other bodies in the heritage sector in Wales; or by accessing the NMRW directly in our public search room and through our public enquiries service. We also engage with our audience through our publications, exhibitions, and a host of other activities.

Met Office Logo

Met Office

The Met Office stores meteorological data and has been an accredited Data Archive Centre (DAC) for MEDIN since 2011 and was re-accredited in 2018. The Met Office is active within the international marine meteorological community and plays an active role in World Meteorological Organisation programs for sharing and developing marine meteorological data and processes.

The Met Office is the DAC for marine meteorological (metocean) data and was established in 1854 as a small department within the Board of Trade and now, more than 150 years on, is the UK’s National Weather Service. In addition to weather forecasting, the Met Office’s Hadley Centre is one the world’s leading climate research centres. The Met Office operates as a Trading Fund within the government’s Department for Science, Innovation and Technology (DSIT) and is required to meet targets as set by its Ministerial Owner.  

Within the area of marine data the Met Office maintains a network of instrumented moored buoys and systems on light vessels, manages a fleet of around 200 Voluntary Observing Ships (some with automated systems on-board), manages the UK Argo programme and deploys drifting buoys in support of the European (E-SURFMAR) and international global drifter programme. The Met Office is active within the international World Meteorological Organisation (WMO) marine programs and DAC staff participate in WMO Task Teams for aspects of Marine Meteorology.

The Met Office Oracle climate database (MIDAS) currently contains over 230 million marine meteorological observations from ships, moored buoys, light vessels, coastal systems and rigs/platforms dating back to 1854 up to the present. Data received over the WMO Global Telecommunications System (GTS) are ingested daily, adding around 36,000 observations per day.

In addition the Hadley Centre maintain a number of key global marine climate datasets including: HadISST - Globally complete sea-ice and sea-surface temperature; HadSST4 - Uninterpolated sea-surface temperature; HadNMAT2 - Uninterpolated night marine air temperature; EN4 - Sub-surface temperature and salinity profiles and analyses; HadIOD - Surface and sub-surface temperature and salinity observations.

Also, a wide range of Met Office ocean model datasets (including the high resolution OSTIA global SST products) are made available via the Met Office Website as well as the Copernicus Marine Service.


All ship and buoy data are exchanged internationally via the WMO GTS and are available through the International Comprehensive Ocean Atmosphere DataSet (ICOADS).

Real-time data (previous 24 hours) from the Met Office moored buoys, light vessels and coastal stations around the UK are available via the Met Office web-site.

All UK Argo float data are archived by BODC and are available through the two Global Argo Data Assembly Centres (GDACS) in France (Coriolis) and USGODAE.

Global marine climate datasets maintained by the Met Office Hadley Centre are made available for download free of charge for scientific research and private study.

Most data are publicly available although some third party datasets may require approval from the original data owner before data can be released. A charge may apply to cover distribution costs and any additional work required. See the Met Office terms of use.


Marine meteorological data from the Met Office is utilised by a diverse range of users including public, commercial and academic organisations for a wide variety of applications. Examples include climate research, legal cases, ship builders, renewable energy companies, university projects etc.
