Lesson plan
SedDB
SedDB was an online database for sediment geochemistry. SedDB was based on a relational database that contained the full range of analytical values for sediment samples, primarily from marine sediment cores, including major and trace element concentrations, radiogenic and stable isotope ratios, and data for all types of material such as organic and inorganic components, leachates, and size fractions. SedDB also archived a vast array of metadata relating to individual samples. Examples of SedDB metadata include sample latitude and longitude, water depth, material analyzed, analytical methodology, analytical precision, and reference standard measurements. As of April 2013, SedDB contained nearly 750,000 individual analytical data points from 104,000 samples. SedDB contents have been migrated to EarthChem Portal.
