METHODOLOGICAL INFORMATION

Description of Dataset
This dataset contains algal biomass and algal nutrient analysis data collected from the Ingoldisthorpe and Langham treatment wetlands during 2025.

The dataset includes:

* algal biomass measurements,
* nutrient concentration measurements,
* and nutrient storage estimates associated with algal material collected from wetland systems.

The dataset was generated to investigate:

* algal productivity,
* phosphorus uptake,
* nutrient storage,
* carbon dynamics,
* and the contribution of algae to nutrient cycling within treatment wetlands.

Description of Data Collection
Algal samples were collected from designated wetland locations including open-water and surface-associated zones within the treatment wetland systems.

Collected algal material was processed and analysed for biomass and nutrient composition.

Measured parameters may include:

* Algal biomass
* Total phosphorus concentration
* Total nitrogen concentration
* Carbon concentration
* Nutrient storage estimates
* Sampling location

Analytical Methods

Algal Sampling
Algal material was collected from wetland surface zones and associated aquatic habitats using standard field collection procedures.

Sample Preparation
Collected algal material was cleaned where necessary, dried to constant weight, and homogenised prior to laboratory analysis.

Nutrient Analysis
Algal phosphorus and nitrogen analyses were undertaken using laboratory digestion and analytical procedures.

Phosphorus analysis was undertaken following acid digestion procedures where applicable.

Carbon and nitrogen analyses were undertaken using elemental analysis procedures where applicable.

Biomass and Nutrient Storage Calculations
Algal biomass productivity and nutrient storage estimates were calculated using measured biomass and nutrient concentration data.

Experimental Conditions
Sampling was undertaken under operational full-scale wastewater treatment wetland conditions during 2025.

Quality Assurance / Quality Control (QA/QC)

* Replicate measurements were collected where applicable.
* Sample preparation procedures were standardised across samples.
* Laboratory analyses followed standard analytical procedures.
* Samples were analysed using calibrated instrumentation.
* Data were checked for transcription and calculation errors prior to analysis.
* Missing values were retained as blank cells where applicable.
