Downcast profiles from Seacat CTD on MacLane pump from R/V Oceanus OC449-02 and OC449-03 in the Eastern North Atlantic and Indian oceans in 2008 (SIRENA project)

In comparing my pump seacat CTD to the ship's CTD, I've discovered that the ship's CTD's fluorescence and beam attenuation are no good, at least for OC449-3. The ship's fluorometer was clearly just not working. &nbsp;The ship's transmissometer misbehaved in a more subtle manner--oceanographically consistent, but of a different pattern than my pump seacat data. &nbsp;I concluded that my pump seacat CTD's transmissometer is the &quot;correct&quot; one by comparing to discrete particulate carbon measurements on particles collected on my pumps. &nbsp;Both particulate carbon concentrations and beam attenuation from my pump seacat CTD show a minimum at 500m at OC449-3 station 3, whereas the ship's CTD shows an anomalous minimum in subsurface beam attenuation at station 2, which is not seem in the particulate carbon concentrations.</p>
