<p><i>Operation description:</i><br />
Discrete analysis of particulate organic carbon (POC) on CTD casts<br />
(hydrography) and ship's underway seawater line.</p>
<p><i>Sampling times and locations:</i><br />
Sampled most CTD casts. One deep cast to 4600m, one mid-depth cast<br />
to 1500m, other casts usually to 100m or 500m. See CTD cast logs and<br />
bottle files for specific times, locations, and bottles for each cast.<br />
See event log for times and locations when sampled underway seawater line.</p>
<p><i>Overall sampling strategy:</i><br />
Normally collected one sample from six depths. Four samples collected<br />
from the 5m bottle on CTD41 for error analysis and method comparison if<br />
samples are run at two locations. Usually took four or more samples in<br />
the mixed layer, one in the thermocline and occasionally one below the<br />
thermocline.</p>
<p><i>Analytical method:</i><br />
Water samples were drawn into a 1.17L polycarbonate bottle using a<br />
latex rubber hose. Sample bottles and caps were rinsed once. Also<br />
took very occasional underway samples - same filling procedure but<br />
no latex hose and water was from outlet in stbd sink, main lab.<br />
Samples were filtered at <20kPa vacuum onto combusted (450C for 12 hrs)<br />
Whatman GFFs. Filters were dried for 12-24 hrs at 23C, <30% humidity,<br />
and stored, folded, in cryovials or aluminum foil (Fred Meyer) envelopes.<br />
Samples were transported to OSU, then acidified with 1ml 10% HCl and dried<br />
again at 60C for 6hrs. Samples were then analyzed for CHN at the UCSB<br />
Marine Science Institute Analytical Lab.</p>
