NZ regional council freshwater nutrient and biomass measurements 2012-2020.

Used to derive nitrogen and phosphorus concentrations and exceedance criteria for managing periphyton in fresh water.

Variables:

  • Site (the number of the data point itself)
  • RC (Regional Council that collected the measurement)
  • RCSiteID (the identifier used by that specific council)
  • SiteName (the Site where the measurement was collected)
  • DateChla (date the chlorophyll-a measurement was collected)
  • Year (Year of collection)
  • Month (Month of collection)
  • Chla ( mg chlorophyll-a per square meter)
  • NOxppb (Nitrous oxide parts per billion)
  • NH4ppb (Ammonia parts per billion)
  • DRPppb (Dissolved Reactive Phosphorus parts per billion)
  • TNppb (Total Nitrogen parts per billion)
  • TPppb (Total Phosphorus parts per billion)
  • DINppb (Dissolved Inorganic Nitrogen parts per billion)
  • EC (Electrical Conductivity)
  • pH (acidity/basicness of the water at the sample location)
  • Temp (water temperature in degrees Celsius at time of measurement)
  • Turbidity (turbidity of the water at time of measurement)
  • Clarity_m (water clarity, in metres, at the time of measurement)

N/A values in the data set refer to an absence of measurement for that specific variable.

This dataset was first added to MfE Data Service on 14 Aug 2019.

This dataset includes three “packages” of information, each with multiple variables. The packages include:

  1. Load – results on mean annual suspended sediment load reported by REC 2 river reach scale for various model scenario variations.
  2. Lakes – results on sediment inflow, outflow, and entrapment in lakes and reservoirs
  3. Coastal – results on sediment inflows, trap efficiency, and sedimentation rates in coastal hydrosystems (estuaries)

For further detail on the modelling methods and discussing results, see Hicks, M., Semademi-Davies, A., Haddadchi, A., Shankar, U., Plew, D. (2019) Updated sediment load estimator for New Zealand. NIWA Client Report No. 2018341CH, prepared for Ministry for the Environment. January 2019. Available online: environment.govt.nz/publications/updated-sediment-...

Note that some portions of this dataset refine and update 2011 modelling on suspended sediment loads across New Zealand, whereas other components, especially the coastal package, report new modelling results.

The StockEx LSL 2021 proposed layer identifies proposed areas of "low slope land" where the Resource Management (Stock Exclusion) Regulations 2020 would apply if the low slope land map was updated as proposed in the "Stock exclusion regulations: Proposed changes to the low slope map" (MfE, 2021) discussion document. The layer shows the area of land defined as low slope land. These areas have a local mean slope is less than or equal to 5 degrees and are below 500m in altitude. Areas of lakes and ponds, estuarine open water, built-up areas, transport infrastructure, depleted grass, tall tussock grassland and urban parkland, as defined in Land Cover Database 5, are also excluded.

Note: The current regulation layer is 'Stock Exclusion Low Slope Land 2020'
