In summary: Filtered water from McLane submersible pumps was passed through acetate filter cartridges impregnated with MnO2. Ac, along with Ra and Th, were sorbed to the cartridges. These were returned to USC and analyzed.

See Methodology Supplemental File (BCO-DMO_227Ac_Methods_for_Arctic_Geotraces_GN01.pdf) for details.

Problem report: Some pump deployments failed to deliver sufficient water (nd).
