Description 
Summary

The data set comprises trace metal and isotope data from the GEOTRACES programme. The data set incorporates the core GEOTRACES parameters for example, Iron (Fe), Aluminum (Al), Zinc (Zn), Manganese (Mn), Cadmium (Cd), Copper (Cu), delta 15 Nitrogen, delta 13 Carbon, Thorium (Th) isotopes, Protactinium(Pa) isotopes, Lead (Pb) isotopes, Neodymium (Nd) isotopes and aerosols, These data are also supported by ancillary measurements. GEOTRACES is global in scope and consists of ocean sections complemented by regional process studies. The ocean sections are designed to cross regions that provide the most information about sources, sinks and internal cycling of trace elements and isotopes (TEIs). The programme started in 2006, with the first International Polar Year - GEOTRACES cruise, and aims to study all major ocean basins over the next decade. Advances in clean sampling protocols and analytical techniques provide an unprecedented capability for measurement of a wide range of TEIs. All measurements collected for GEOTRACES will use ultra clean techniques as many of the countries involved have built specialist winches, wires and conductivity-temperature-depth (CTD) units specifically for this programme. SAFe standards (standards developed following the Sampling and Analysis of Fe (SAFe) cruise) and GEOTRACES inter-calibration protocols provide quality control.The GEOTRACES programme builds on the data collected during the Geochemical Ocean Section Study (GEOSECS) in the 1970s. The potential afforded by advances in sampling protocol and analytical techniques had not been realized since then, largely because of a lack of coordinated research. The GEOTRACES programme includes scientists from approximately 30 nations, although the key countries are the UK, Germany, France, Spain, Sweden, Netherlands, USA, Canada, New Zealand, Australia, Japan, India and China.
