Presentation Transcript

  1. Density Inversions in the Ocean • Ben Kravitz

  2. Potential Density Potential Density (ρθ) is the density a parcel of water would have if raised adiabatically to the surface without a change in salinity. σθ = ρθ - 1000

  3. Double Diffusion warm fresh water cool salty water http://www.phys.ocean.dal.ca/programs/doubdiff/doublediffusion.html

  4. Kelvin-Helmholtz Instability

  5. Places with Stable Density Inversions Mediterranean Sea outflow Persian Gulf and Gulf of Oman Red Sea and Gulf of Aden

  6. Mediterranean Sea outflow into Atlantic Ocean sea surface σθ = 27.85-27.90 -1200 m intruding layer of warm, salty water density inversion σθ naturally decreases moving upward Atlantic water at σθ = 27.85-27.90 -1500 m
