• Nitrate (Lloyd Moore)
• Phosphate (Lloyd Moore)
• Silicate (Lloyd Moore)
• Oxygen
• TCO₂ (NOAA) - Crossover results are from initial Feely et al. (1999) study. Additional analysis was not conducted because there were so few deep samples and the Spring cruise was an adequate representation of the region. No adjustments have been formally recommended.
• Crossovers:
  Stations-2
