Abstract

Radium isotope (223Ra, 224Ra, and 226Ra) measurements from CTD and underway water samples.

Cite Dataset

Water samples for radium isotope analysis were collected from both the ship’s clean underway intake system (‘U’ designator in data sheet) and niskin bottles attached to the CTD rosette (‘C’ designator in data sheet).  Salinity data derived from ship’s clean underway intake system with SBE 21 SEACAT Thermosaliograph.
