1. The diagram below shows a simple, "two-box” model for the ocean, divided into surface and deep parts: atmosphere pO2 = 0.21 atm gas exchange surface ocean [PO43-) = 0 [O2] = saturated T = 25°C biomass production 200m t sinking downwelling upwelling respiration deep ocean [PO43-) = 1.9 UM [O2] = 175UM T = 4°C 4000m A) Assuming the area of the ocean is 5x1013 m2, the surface layer is from Om to 200m depth, and the deep ocean is from 200m to 4000m depth, calculate the volumes of the surface and deep boxes. The Henry's Law constant for O2 as a function of temperature is given by: , KA(7) = k398 (28) k = T where K4298 is the constant for O2 at 298K (25°C), K4298 = 1.2x10-3 M/atm, T is the temperature in Kelvin, and the constant C for Oz is 1700.
