The hafnium-neodymium isotopic composition of Atlantic seawater

Abstract:

The first full water column hafnium isotopic compositions of Atlantic seawater have been obtained at seven locations from the Labrador Sea to the Drake Passage. Despite subpicomolar concentrations in seawater, a precision of the Hf isotopic measurements of < 0.7 εHf units was achieved. An overall εHf range between - 3.1 in the Labrador Sea and + 4.4 in Antarctic bottom water was determined, the distribution of which broadly reflects continental weathering inputs. Within particular water co...
