Water quality monitoring data collected in the Maldives by the South Asian Nitrogen Hub, 2022-24
[This dataset is embargoed until December 15, 2026]. Sites were monitored for key water quality indicators, including: water quality parameters (temperature, pH, electrical conductivity, salinity, dissolved oxygen and turbidity), water samples collected for subsequent nutrient analysis (for dissolved inorganic nitrogen and phosphate), and where possible seagrass or algal samples were collected for isotopic composition. Water quality data was collected across a range of sites in Laamu atoll between 2022 and 2024 to develop a baseline understanding of water quality, to help characterise nutrient loading and identify potential sources of nutrient pollution. The sampling was conducted on varying spatial and temporal scales. This included a variety of island types (e.g., inhabited, uninhabited, agricultural, tourism islands, pristine patch reefs), and within individual islands. Sampling was conducted across a spectrum of uses-types of different sites (e.g., densely populated areas, versus heavy agricultural areas, vs rural areas etc) between different seasons (wet and dry seasons) on monthly, quarterly, bi-annual and annual time-windows. Repeat sampling was conducted on several sites several times a year and over 2 years to get a sense of change over time and within season.

Water quality data was generated using multi-parameter probes in-situ (either Hach or Aquaprobe) which were calibrated as per instructions prior to each use for each parameter. Nutrient measurements were performed spectrophotometrically at either SAMS (Scottish Association for Marine Science in Oban, UK; or at the National Centre for Sustainable Coastal Management in Chennai, India), with samples stored and transported frozen. Elemental and isotopic compositions of seagrass and macroalgal samples were generated through stable isotope ratio mass spectrometer, performed at the University of Edinburgh, UK, with samples stored and transported frozen prior to analysis. Manual checks have been performed on the data to look for any error in data entry or values reported outside the expected range. This data is heterogenous in nature. Any outliers were then investigated and corrected where appropriate
