378S was a transit from Tahiti to Panama and though no science party was on board, the technical staff continued to regularly collect surface water samples for additional studies by 378 scientists.

Alkalinity Titrator: Run after every sampling, twice daily. Normally it would take two runs of IAPSO to reach a value within 2% error after which the sample was run.
Cary Spec: Only one phosphate run of 21 samples and blanks. Ammonia was not done because scientists expected values lower than detectable limits. The software was giving an error when opened and Eric Moortgat advised from shore to change the bulb. The filament was broken and the new bulb solved the problem and the run went smoothly with a good standard curve. Values for samples were still very low.
