<p><b>CTD-related instrumentation consisted of:</b><br />
- a Seabird Electronics (SBE) 911plus CTD with:<br />
- SBE-5 pumped SBE-3 temperature, SBE-4 conductivity and SBE-43 dissolved oxygen<br />
sensors.<br />
- SBE-5 pumped secondary SBE-3 temperature and SBE-4 conductivity sensors.<br />
- Seapoint Sensors, Inc. SCF chlorophyll fluorometer.<br />
- 25-cm Wetlabs C-star transmissometer.<br />
- Biosherical Instruments Inc. photosynthetic ally active radiation (PAR) sensor, model<br />
QSP200L4S.<br />
- Datasonics sonar altimeter, model PSA-900D.<br />
- a SBE 32 24x10-litre Carousel water sampler.<br />
- Ocean Test Equipment Standard BES external-spring Niskin-type water-sampling bottles.<br />
- Salinity sample bottles.<br />
- CTD winch with 10-km 10.5-mm single-core seacable.</p>
<p><b>Performance:</b> With the exception of issues noted below, the CTD-related instrumentation apparently<br />
functioned to specification and was operated essentially according to accepted practices for the duration of<br />
the voyage. A total of 85 one-cast CTD stations were completed, labelled u3502 to u3743.</p>
<p><b>PAR Sensor:</b> The initial CTD PAR sensor experienced an intermittent fault that manifested as a time<br />
variable offset, both cast to cast and, less evidently, within casts. It was eventually replaced with a formally<br />
identical spare unit for station u3719 cast 1 and subsequent casts.</p>
<p><b>Secondary Conductivity Sensor:</b> The initial secondary conductivity sensor eventually developed a clear<br />
fault (during station u3740 cast 1). It was replaced with a formally identical spare unit for station u3740 cast<br />
1 and subsequent casts. The development of this fault was perhaps somewhat progressive, as possibly<br />
indicated by slight shifts in the primary-secondary conductivity difference on casts before station u3740 cast 1.</p></div>
