Upper boundary conditions used for the simulated soluble and solid species in the various scenarios defined in section 2.8.

For solutes, these are the concentrations in the bottom boundary layer above the DBL, for solids the depositional fluxes. Between the dates given here, values were linearly interpolated.

就溶质而言，此处的数值为扩散边界层（Diffusion Boundary Layer，DBL）上方底部边界层中的浓度；就固体颗粒而言，则为沉积通量。在所给定的日期区间内，各数值均通过线性插值得到。
