The artic ocean transports silicon (Si) at 13.14 kmol/s and phosphate (P) at 3.8 kmol/s into the North Atlantic. This accounts for 12% of the silicon and 90% of the phosphate in the southward fluxes measured at 47 degrees north in the North Atlantic. The document asks three questions: 1) What is the total southward flux in kmol of each nutrient at 47 degrees north? 2) If the southward flow volume is 3 Sv, what are the mean concentrations of P and Si in umol/L assuming full mixing? 3) Which water mass from a provided diagram do the calculated P and Si concentrations most closely relate to?

1. Look at the artic ocean, it transport a total of Si- 13.14 kmols-1 & P (3.8 kmol s-1) to the N.
Atlantic
This in turn results in provision of 12% (si) & 90% (PO4) of the South ward fluxes estimated at
47 degrees north in N. Atlantic
Question 1
Measure total southward flux (100%) in kmol of each nutrient at47 degrees north
Question 2
If net southward flow volume of this water is 3 Sv, what is the mean concentration in Umol L-1
of P and Si in this water, assuming it is fully mixed
Question 3
Which of the water masses in the diagram below do your calculated concentrations of P04 & Si
most closely relate to?
