Figure 17. Modern sediment trap data from the northeastern Pacific showing how the ratio of CaCO3 rain to Corg rain varies with distance from shore and latitude. High CaCO3 rain occurs offshore out of the coastal upwelling region and in the northern part of the transition zone to the Alaska Gyre, where SST is between 7× and 9×C.
