Data on dissolved oxygen, temperature and salinity in estuarine and coastal
waters were obtained from field-based monitoring programmes in England,
Scotland, Wales and Northern Ireland under EU Directives (the Water Framework
Directive, WFD, the Urban Waste Water Treatment Directive, UWWTD, and the
Nitrates Directive, ND). These data have been held in institutional databases,
and used in national and regional assessments of ecological or environmental
status, which describe summary statistics and overall outcomes using physical,
chemical and biological parameters/indicators and generally do not present the
underlying data. For recent work on trends in dissolved oxygen concentrations
in UK waters from 1990 to 2018 (Painting et al. in prep), the raw data on
dissolved oxygen (DO) concentrations and all supporting metadata (e.g.
latitude, longitude, water column depth, sample depth, temperature, salinity)
for coastal and estuarine waters were extracted from institutional databases
and combined into one dataset, which is provided here.
