The hafnium and neodymium isotope composition of seawater in the Atlantic sector of the Southern Ocean
- T. Stichel, M. Frank, Joerg Rickli, Brian A. Haley
- Geology
- 1 February 2012
We present the first combined dissolved hafnium (Hf) and neodymium (Nd) concentrations and isotope compositions of deep water masses from the Atlantic sector of the Southern Ocean. Eight full depth… Expand
Southern Ocean control of silicon stable isotope distribution in the deep Atlantic Ocean
- G. F. D. Souza, B. Reynolds, +4 authors B. Bourdon
- Geology
- 1 June 2012
The fractionation of silicon (Si) stable isotopes by biological activity in the surface ocean makes the stable isotope composition of silicon (delta Si-30) dissolved in seawater a sensitive tracer of… Expand
The influence of water mass mixing on the dissolved Si isotope composition in the Eastern Equatorial Pacific
Silicon isotopes are a powerful tool to investigate the cycling of dissolved silicon (Si). In this study the distribution of the Si isotope composition of dissolved silicic acid (δ30Si(OH)4) was… Expand
Neodymium isotopic characterization of Ross Sea Bottom Water and its advection through the southern South Pacific
- C. Basak, K. Pahnke, M. Frank, F. Lamy, R. Gersonde
- Geology
- 1 June 2015
Since the inception of the international GEOTRACES program, studies investigating the distribution of trace elements and their isotopes in the global ocean have significantly increased. In spite of… Expand
Beryllium 10, thorium 230, and protactinium 231 in Galapagos microplate sediments: Implications of hydrothermal activity and paleoproductivity changes during the last 100,000 years
- M. Frank, Jörg-Detlef Eckhardt, +4 authors A. Mangini
- Geology
- 1 August 1994
Biogenic particle fluxes from highly productive surface waters, boundary scavenging, and hydrothermal activity are the main factors influencing the deposition of radionuclides in the area of the… Expand
Deep-sea Fe-Mn Crusts from the Northeast Atlantic Ocean: Composition and Resource Considerations
- S. Muiños, J. Hein, +5 authors F. Abrantes
- Geology
- 1 January 2013
Eighteen deep-sea ferromanganese crusts (Fe-Mn crusts) from 10 seamounts in the northeast Atlantic were studied. Samples were recovered from water depths of ∼1,200 to ∼4,600 m from seamounts near… Expand

- Geology
- 15 January 2020
After publication of our paper (Cao et al., 2016), we recently detected an unaccounted for matrix effect in the seawater Ba isotope measurements. Because our data were among the first seawater Ba… Expand
