OTHER_COMMENTS: 
0.05 um pore diameter, 47 mm polycarbonate Nuclepore filter sample, with average flow rate 10 Lpm (STP).
Filter shaken in 6 mL of 0.02 um filtered deionized water (Anotop) for 20 min. 
Dilutions (15-fold) were made in 0.02 um filtered deionized water.
Sample was heated at 95 deg C for 20 mins and then cooled to room temperature for analysis.
Immersion freezing performed at -0.3 K min-1.
INP per mL were derived using 32 wells, each containing 50 microlitres of re-suspension solution.
Confidence intervals for INP are expressed in the same units as the number of INP.
They are binomial sampling confidence intervals (95%) derived using the formula (No. 2) recommended by Agresti and Coull (1998).
Data is final, corrected for instrument background and for sampling contamination determined from blank filters (n=7).
