A two-phase approach to the simulation of the combined isotope/salinity signal of marine ice
A modified boundary layer box diffusion model is used to simulate the production of the combined oxygen isotope/salinity signal of a body of marine ice. The final signal is considered to be the result of fractionation and segregation processes occurring first upon the formation of frazil crystals in...
