The data values presented were transposed from the information in Maskelyne's original paper into the data file included with this submission by the authors of this dataset. The data have been subjected to various types of quality control by the authors including, in particular, consistency of the tidal content of the sea level time series with modern expectations, and the data have been studied within a modern reanalysis (submitted for publication). The purpose of this dataset is to make the Maskelyne measurements more accessible in an electronic form for the benefit of future researchers.

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. true This dataset was created by the organisations with the "originator" role in this metadata record following digitisation of the original historic dataset, complemented by modern in-house data processing and quality control procedures. The data were then provided to the British Oceanographic Data Centre (BODC) for long-term archive and data publication in the BODC Published Data LibraryInstrument(s) used to collect data: sea level recorders.
