Acknowledgments

This project, including: the collection and chemical analysis of the 2015 radionuclide samples; the combined physical analysis of the available radionuclide datasets and related observations; as well as the modeling component, is primarily supported by NSF grant OCE-1356630.

Ship time for the collection of radionuclide water samples along the GO-SHIP P16N line was supported by the National Oceanic and Atmospheric Administration.

The Gordon and Betty Moore Foundation supported the collection and chemical analysis of the June 2011 coastal survey (aka. the KOK cruise) used in this project.

The Deerbrook Charitable Trust also supported analysis of a number of the water samples used in this project.

We would like to thank the captains, crew and science parties of all the cruises for their diligent efforts that led to successful collection of the many hundreds of 20L-water-samples used for by project.
