# How do integrated geochemical data systems enable new scientific discoveries?  Geochemical compilations of enormous numbers of dense, statistically significant measurements have driven large, global-scale scientific discoveries. Examples include studies on diversity in MORB composition \citep[e.g.]{Gale_2013}, global distributions of elements in the Earth’s derma layers \citep{Rauch_2011} \citep{http://dx.doi.org/10.1016/j.gexplo.2011.05.008}  and global patterns of intraplate volcanism \citep{Conrad_2011}. \citep{http://dx.doi.org/10.1038/ngeo1111}.  New analytical methodologies allow for increasing rates of data collection that should translate to more ground-breaking scientific discoveries. With this anticipated increase, it is not feasible for single scientists to compile “all available global data” from the existing literature. This inability highlights the need for data systems to provide support for data discovery, access, and analysis to investigators, who are otherwise left with a disorganized heap of un-usable data. The IEDA (Integrated Earth Data Applications) EarthChem data facility (http://www.earthchem.org) develops and operates digital data collections focused on the geochemistry of rocks and sediments from a wide range of global geographic settings. EarthChem citations show that its use is extending far beyond its rock and sediment geochemistry origins (http://www.earthchem.org/citations). For example, EarthChem has been cited in diverse scientific studies such as prediction of natural base-flow stream water chemistry (Olson and Hawkins, 2012), a prototype of a web-based relational database for archaeological ceramics (Hein and Kilikoglou., 2011), and strontium and oxygen isotope fingerprinting of green coffee beans and its potential to proof authenticity of coffee (Rodrigues et al., 2010).
