MSCl 305 Spring 2023 Assignment 5: Vertical diffusive transport DUE Week 7: 7/21/23 Upon completion of this learning module; you should be able to (1) use dimersional analysis to convert between various seientific units; (2) use sigma-t ( ) to calculale the density of seawater given temperature and salinity; (3) calculate the concentntion of a major ion using salinity and Marcet's Principle of Constant Proportions; (4) calculare the molecular diffusive flux of a major (conservative) ion of sembater using Fick's First Law. Calculate the flux of Mg2+ (in ecm2y1) by diffusive mixing between two water masses in the north Atlantic, by following the steps below. The TS diagram on the right shows T and S values collected from a CTD profile in the north Atlantic. The linear relationship suggests that there are two water masses mixing conservatively, according to Fick's First Law (zo below represents the shallower water depth). Flux=Dczz0[C]2[C]c0 1. (0.3 pts) Assuming Mareet's Principle of Constant Proportions bolds, and using the concentnation values of major ions in Table 2. (0.3 pts) Using the salinities and temperatures of the two waler masses and the i table in your supporting data package (from 305 Lab), comert the density of each water mass to units of kgL1 3. (0.6 pts) Using your answers in 2, cotrent the [Mg?r / you calculated in 1 for the fio water masses to aruts of M2Mg2. cm3 sw 5. (0.5 pes) Complete the flux calculation using a diffusion cocflicient of Mg2,Di=5104cm251, Remember to report your answer in gMg14cm2y1 MSCl 305 Spring 2023 Assignment 5: Vertical diffusive transport DUE Week 7: 7/21/23 Upon completion of this learning module; you should be able to (1) use dimersional analysis to convert between various seientific units; (2) use sigma-t ( ) to calculale the density of seawater given temperature and salinity; (3) calculate the concentntion of a major ion using salinity and Marcet's Principle of Constant Proportions; (4) calculare the molecular diffusive flux of a major (conservative) ion of sembater using Fick's First Law.
