About SedDB Data

The SedDB database contains marine sediment geochemical data, compiled primarily from the published literature.

Analytical Data

SedDB accommodates the full range of analytical values, from major and trace element concentrations to radiogenic and stable isotope ratios, in both inorganic and organic matrices, for diverse suites of samples (e.g., seafloor and sub-seafloor, lakes and rivers, sediment traps, nodules) and subsamples of material such as individual biological components, leachates, and size fractions.

Metadata

SedDB contains abundant information about the analytical procedure and data quality, and a wide range of contextual information about the samples (e.g., spatial coordinates, position within a core, lithology, age).
Compilation of data started in 2006, and data holdings are still limited. New data are being added to the system on a regular basis.
