161 Sample ID Deposition

---

A Sample ID is assigned to each sample that is analysed in the lab.

The Sample ID allows a clear coding if the same samples gained in the field are used in lab analysis with different temporal resolution.

The Sample ID should be unique in combination with Plot, Sampler_ID, Sampler code, Start date, and period for each sample used for analysis.

Examples for PLD and DEM/DEO for Sampler Code 1 = Throughfall:

PLD:

!Sequence, country, plot, sampler, sampler_ID, […], date_monitoring_1st, date_monitoring_last, periods, sampler_model, […] other_observations

0001 04 4321 1 […] 001 010111 311211 12 1 […] standard sampling

0002 04 4321 1 […] 002 010111 311211 12 2 […] parallel with harmonized samplers

0003 04 4321 1 […] 003 010111 311211 04 1 […] quarterly aliquot for heavy metals

DEM:

!Sequence, plot, date_start, date_end, period, sampler, sampler_ID, sample_ID, V_sampling, quantity, pH, […], other_observations

0001 4321 010111 290111 1 1 001 0001 1 0031 5.6 […] standard sampling

0002 4321 290111 260211 2 1 001 0002 1 0042 5.4 […] standard sampling

Too little volume for any analyses; sample pooled with following sample period: Same Sample_ID, quantity, and results for both periods:

0003 4321 260211 250311 3 1 001 0003 9 0032 5.5 […] too little volume, pooled

0004 4321 250311 220411 4 1 001 0003 1 0032 5.5 […] standard sampling

[…]

Parallel equipment (harmonized sampler) installed on the same plot (Sampler_ID =2):

0013 4321 010111 290111 1 1 002 0012 1 0021 5.5 […] parallel equipment

0014 4321 290111 260211 2 1 002 0013 1 0032 5.3 […] parallel equipment

[…]

DEO

Quarterly aliquot for heavy metals (Sampler_ID = 3):

!Sequence, plot, date_start, date_end, period, sampler, sampler_ID, sample_ID, V_sampling, quantity, Al, […] other_observations

0025 4321 010111 010411 1 1 003 0023 1 0035 1.06 […] aliquot only for hm

0026 4321 010411 010711 2 1 003 0024 1 0046 2.04 […] aliquot only for hm
