Acid manipulation field experiment in North Wales and the Peak District (2015-2016): Litter decomposition, Tea Bag Index and pore water chemistry data

Data was collected from an acidity manipulation field experiment which took place between 2015-2016 at two locations in the UK; Migneint in North Wales (3°48.8′ W, 52°59.6′ N), and Peaknaze in Northern England (1°54.5′ W, 53°28.3′ N). Water samples were filtered and stored at fridge temperature in amber glass bottles until analysis. Sample analysis took place within 1 week of collection at the Centre for Ecology and Hydrology (Bangor).

Litter and tea bag samples were stored at fridge temperature and processed within one month of collection. Analysis took place at the Centre for Ecology and Hydrology (Bangor). Water extracts were filtered, stored in amber glass bottles at fridge temperature and analysed within one week of the extraction.

All instruments measuring water chemistry were calibrated prior to the analysis, and runs included calibration standards and check solutions of known concentrations. Checks were include at the start, middle and end of the runs to check for drifts in measurements. Aquacheck solutions were also included for QA purposes.
