Description
Summary:Dissolved yttrium and rare earth elements (YREEs) have been measured in the Antarctic Circumpolar Current Region, southwest of Australia. Their vertical features are fairly smooth, irrespective of the differ-ent water masses in the water column, suggesting that the biogeochemical processes including reversible scavenging reactions and sinking particulate matter are important control on their distribution. Compari-son to the previous data at nearly the same latitude of ~40°S in the Southern Ocean of the Atlantic sector (German et al., 1995) indicates that our concentrations are significantly depleted in the lighter REEs. The difference in their mean concentrations systematically decreases with increasing atomic number, i.e., 67%
