• Major goals
• Elucidate the air-sea interaction and subsurface
  oceanic variability associated with major climate
  phenomena in the eastern tropical Indian Ocean
  such as the Intraseasonal disturbances, the
  Wyrtki jets, the monsoonal variability, and the
  Indian Ocean Dipole Mode.
• Contribute as part of the CLIVAR/GOOS basin-wide
  Indian ocean mooring array, from which data will
  be utilized in climate prediction models for
  better prediction skill.
