Hafnium and neodymium isotope variations in NE Atlantic seawater

The 176Hf/177Hf ratio of seawater is measured directly with 143Nd/144Nd in a composite vertical profile in the NE Atlantic. The value of εHf of intermediate and deep water exhibits little variation and averages +1.0 ± 0.8; surface water shows a wider range,-5.7 to +3.3. While intermediate and deep w...
