To obtain comparable pollen deposition data at all leaf measurement sites, we additionally used PMF passive samplers (Additional file 1: Figure S10) standardised according to VDI 4330-3 [19] and CEN-TS 18617-1 [47].
Two additional high-volume air samplers with five-stage impactors were deployed in the first row to obtain the distribution of toxin-containing aerosol particle size.
Later incarnations replaced the keyboards and samplers with an additional guitarist, and incarnations after that added a multi-instrumentalist whose main role was as a bassist but also played guitars and keyboards on a number of songs.
The convergence of these samplers are illustrated in Additional file 4: Figure S1.
Similarly, Bayesian applications require careful inspection of MCMC samplers for proper convergence and additional time should be devoted to exploring sensitivity of posterior estimates to prior distributional assumptions.
Additional surveys using dredges, grabs, and other benthic samplers have collected invertebrates and new species.
To see whether all parallel samplers converge to the same distribution we plotted (Additional file 9: Figure S3) the log-marginal log(P(A i | R )) of the samples drawn by the samplers.
To see whether all parallel samplers converge to the same distribution we plotted (Additional file 5: Figure S2) the log(P(A i | R )) for a sample dataset.
Moreover, we strive for identifying additional parameters that might affect the solute flux into and inside DGT samplers.
Additional techniques are available including composite sampling and the use of passive samplers (e.g., polar organic contaminant integrative sampling, POCIS) which give an integrated sample over a period of days to weeks.
