  • Palaeolithic to present day digital data fror archaeology 
  • No limitations on collections of data 


Users of data archived and hosted by the ADS are requested to agree to terms and conditions of use. The Archaeology Data Service (ADS) levies no charge to use its collections when used according to these terms. It is the aim of the ADS to provide integrated access to a variety of data sets at no cost to end users. This aim can only be achieved if the organisations that supply data can be assured that their own rights are protected. Consequently, use of the catalogue is covered by a variety of legal instruments to protect us, our users and those who supply data to us. The Common Access Agreement asks that users be fair and reasonable in their use of the data supplied through the ADS.

The ADS levies no charges, there are no documents to sign and none will be applied retrospectively. We do not hold information on specific users. In return we ask that you acknowledge the source and copyright of any data you use, that you tell us of any errors you find and that, if you undertake any work based substantially upon it, that you tell us about it and send us a copy of any subsequent publication. The data must not be sold or supplied to a third party. The data should only be used for teaching, learning and research purposes. By 'teaching', we mean directed teaching undertaken with a designated tutor in a formal setting. By 'learning', we mean self-directed study, whether or not attached to an educational institution, including the educational activities undertaken in museums, libraries and cognate institutions. By 'research', we mean any work undertaken for the advancement of archaeological knowledge and/or the understanding of the historic environment. Such work may be commercially sponsored or it may be funded by academic bodies or learned societies, or it may be unsupported, but it is a condition of use that the results are placed in the public domain and made freely available for others to use according to the normal principles of professional and academic practice.


All data held and archived by the ADS is available through our search interface ArchSearch. ADS holdings are split between 'monument inventories' and 'archives' and this division is explicit on the ADS website with separate search mechanisms for each. The archives themselves are classified into a number of categories such as subject, programme and region. By using the faceted classification system, a user can constrain the archive search. The results themselves can then be ordered alphabetically by title or chronologically on the year of their release. The ArchSearch faceted classification system works on 'where, what and when' searches. If a user knows exactly what part of the country they are interested in, ArchSearch also features an interactive mapping panel that allows the selection of a particular area of interest and displays results.

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 1116,000 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 DAC for MEDIN since 2011 and was re-accreditted in 2018. The Met Office is active within the international World Meteorological Organisation (WMO) - Intergovernmental Oceanographic Commission (IOC) Joint Commission for Oceanography and Marine Meteorology (JCOMM).

The Met Office is the data archive centre for marine meteorlogical (metocean) data and was established in 1854 as a small department within the Board and 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 Business Innovation and Skills (BIS) 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 300 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) - Intergovernmental Oceanographic Commission (IOC) Joint Commission for Oceanography and Marine Meteorology (JCOMM).

The Met Office Oracle climate database (MIDAS) currently contains over 130 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 16,000 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; HadSST2 - Uninterpolated sea-surface temperature; MOHMAT - Uninterpolated night marine air temperature; EN3 - ENSEMBLES: quality controlled in situ ocean temperature and salinity profiles; HadGOA - Global subsurface ocean analysis of temperature and HadDTR - A climatology of the diurnal temperature range of the Sea Surface. 

Also, a wide range of Met Office ocean model datasets (including the high resolution OSTIA global SST products) are made available via the Godiva2 Live Access Server run by the NERC ESSC as part of the wider NCOF (National Centre for Ocean Forecasting) consortium. 


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.
