Research Spotlight: New samples taken along Pacific Antarctic Ridge


  • Ernie Tretkoff


Understanding the geochemistry along ocean ridges around the world can help scientists understand the spatial dynamics and evolution of the mantle. Building on previous sampling of the Pacific Antarctic Ridge, Hamelin et al. collected data on major elements; trace elements; and strontium (Sr), neodymium (Nd), and hafnium (Hf) isotopes in basalts gathered along the ridge from 41° to 53°S. These were the first Sr-Nd-Hf isotope data collected in that area, a section of the Pacific Antarctic Ridge that does not have hot spots,which would affect the geochemistry.
