<p><strong>Notes</strong><br /><em>A. CHN</em><br />
1. Both silver and QMA samples were analysed by punching a sub-sample using a 4.16mm punch.<br />
These were then acidified with 20ul of 50% HCl in silver cups, dried, reweighed to estimate<br />
carbonate loss (squat-all) and combusted in our Carlo-Erba.</p>
<p>2. The number of punches taken for each sample varied according to how much material it had.<br />
The spreadsheet calculates the umol C on the TOTAL filter based on the # of punches, punch<br />
area and effective filtration area. To get the effective filtration area for a silver filter<br />
I measured the diameter that material covered to be 22.88mm. For the QMA I took it to be 140mm.</p>
<p>3. For the 2 overloaded samples 41C and 105C, I (Trull) used the weight ratios to calculate<br />
the total umol C that must have been on the filter. The tare of empty petri-dish with lid<br />
and blank silver filter was 8.91639g. Estimating the total material weight by either using<br />
Charette's initial weight and subtracting this tare, or using Trull's final weight (minus the<br />
same tare) and adding back in your and my sub-aliquots agrees to better than 3mg (105C) and<br />
1.5mg (41C) in comparison to ~400mg totals, suggesting errors of under 1% from the tare correction.</p>
<p>4. Measured QMA and Silver filter blanks were small (single determinations, and not true field blanks)</p>
<p><em>B. 13Corg</em><br />
1. Samples prepared exactly as for CHN. Blank determinations again from single blank determinations.<br />
Standardisation to NBS22 Oil, same as for SizeFractionatedPumped Particles - see that sheet.</p>
<p>2. Blank corrections from single Ag and QMA samples</p>
