  1. OCN 5401 Chapter 8 Distribution of Temperature and Salinity Instructor: Dr. George A. Maul gmaul@fit.edu / X 7453

  2. Map of Hecataeus of Miletus (ca. 550 BC – 476 BC) a student of Greek geographer Anaximander (ca. 610 BC – 546 BC), a student of Thales of Miletus (ca. 624 BC – 546 BC).

  3. Why do these sea surface salinities vary? E-(P+R)

  4. COULD THE OCEAN DISSOLVE MORE SALT? SALINITIES IN GREAT SALT LAKE EXCEED 250 g/kg!!

  5. Sea surface temperatures (SST) in the world ocean during August. Why do these sea surface temperatures vary? H= m·CP·ΔT

  6. Double Diffusion and Salt Fingering simplified equation of state =0.2

  7. Water mass formation in the Southern Ocean

  8. Water Mass Formation Southern Ocean

  9. Water mass formation in the Arctic Ocean Fram Strait

  10. Connecting the two: Water Mass Formation in the Atlantic Ocean advection = diffusion

  11. Labrador Sea Water formation temporal variability Doesn’t seem to be ENSO related: 72-73, 82-83, 87-88, 97-98, 09-10.

  12. Atlantic Meridional Overturning Circulation • “The AMOC is defined as the total (basin-wide) circulation in the latitude depth plane, as typically quantified by a meridional transport streamfunction.” • THC is “currents driven by fluxes of heat and fresh water across the sea surface and subsequent interior mixing of heat and salt.” Rahmstorf (2002).

  13. Temperature-Salinity (T-S) Diagram

  14. Ocean basins, sills, and fracture zones

  15. Deep Western Boundary Current Inverted Echo Sounder

  16. World Ocean Circulation Experiment using human made chemicals as tracers

  17. Meddies RAFOS (range and fixing of sound)

  18. Oceanic Microstructure Fine Structure Profiler

  19. Langmuir Circulation Turbulence, convection, Stokes drift

  20. OCN 5401 Chapter 8 Questions?
