It also depends on the amount of fresh water in the source (fresh water has less of the heavy isotopes). | |

clarify reference to paper

In this case, the 'target' is simply the location of the ice core. (You shouldn't use the comment feature to provide an answer.) | |

It might have been the Gulf of Mexico in summer, or the Denmark Straits in winter, so a great variety of sources and temperatures.. | |
