1. (20 pts) The preformed phosphate concentration in Atlantic Ocean waters with potential a temperature of 1.20C and salinity of 34.67%o has been estimated to equal 1.36 umol kg?. Given the phosphate concentration in a water sample with a potential temperature 1.20C from the Pacific sector of Antarctica was 2.15 umol kg*!, calculate the AOU and then estimate how much organic carbon was re-mineralized within the water parcel. Final answer should be in umol/kg units
