Question 4

Which of the following accurately describes ¹⁸O/¹⁶O ratios of the worlds oceans?

Accepted Answer

A)  Because ¹⁸O evaporates more readily than ¹⁶O, the oceans have a higher relative abundance of ¹⁶O during warm periods and a more balanced ratio when there is less evaporation. 
B)  The higher the ratio of oceanic ¹⁸O/¹⁶O, the warmer the temperatures because the ¹⁶O will have been mostly evaporated from ocean waters. 
C)  During periods of colder temperature ¹⁶O is locked up in snow and ice and the oceans have a higher preponderance of ¹⁸O; during warmer periods the isotope ratio is lower. 
D)  The ¹⁸O/¹⁶O ratio is low during colder temperatures because temperatures are too low for evaporation to be effective and both isotopes remain in the ocean.
