Question

63. (30 pts) The amount of COa in the Atlantic is far less than in the Pacific due to global ocean circulation and the build up of respiratory products in the ocean between times it is ventilated with the atmosphere. There are long-term repeated cruises in both ocean basins to investigate how saturation indices () are changing in the ocean due to climate change. ( 1 8 pts) Complete the table below and use the data collected at stations at 20°N latitude in both ocean basins to determine where the lysocline and CCD are based on this modern data. Ksp 3.3 × 10", mol kg Salinity Ocean Basin Atlantic 248 200 1000 4000 200 1000 4000 34 35 35 35 35 36 101 105 203 47 73 Pacific 63a. (6 pts) What is your best guess of the location of the lysocline and CCD in the two ocean basins now. Hint(z): you should have two depths here, one for each the lysocline and CCD 63b. (6 pts) Using the WOCE data collected in the early 2000's, do you think the ocean is changing? And is it changing enough we should be worried about it? Afantic WOCE Data VOCE Data 60 S 40°S 20 S o 20 N 40° N 60 N 80 N

Explanation / Answer

saturation index = log(IAP/KSP)

The lysocline is the depth in the ocean below which the rate of dissolution of calcite increases very rapidly.

CCD is the depth in the oceans below which the rate of supply of calcium carbonate lags behind the rate of solvation.

lysocline of Atlantic is 3000 to 3500 m for both

C)

By seeing the grapg contour it is clear that ocean is changing very rapid that we should worry about this
