Ocean Mixing Experiment

1
Ocean Mixing Experiment

• Tommi Bergman, Ambarish Karmalkar,
• Shreethala C., Abubakr Salih

2
Modifications

• Vertical mixing coefficients (ABACK and DBACK)
  increased by factor of 25
• No other modifications

3
Hypotheses

• Increased vertical mixing
• Mixed layer thickness increase
• SST and SAT decrease
• Build-up of sea ice at high latitudes
• Salinity profile change

4
Mixed layer thickness

• Mixed layer thickens
• Some anomalies especially around Antarctica

5
Sea temperature

• Equatorial surface layer cools
• At larger depths water temperature increases

6
SAT

• Global temp reduces, but polar temp increases

Control
7
Sea ice
8
Salinity vertical profile
Salinity increases at poles, especially north pole
9
Ocean circulation

• Compared to the control run the poleward mass
  transport increases

CO2 response

• CO2 burden has a increasing trend all through the
  20 years
