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
