Goals:

  • Compare CTD and bottle T, S, O2, sigma-0
  • Compare a single profile (South Atlantic)
  • Compare an entire section

To accomplish this, one will:

  • Use and analyze from various sources:
    • Bottle casts
    • CTD casts
    • Statistically-compiled multi-year average data WOA05
  • Explore differences in depiction of:
    • Ocean temperature
    • Salinity
    • Dissolved oxygen
    • Density
  • Analyze three data types at one location (one profile per data type)
  • Analyze vertical section plots from three data types
