"Specimen analysis records - raw data for 26 elements" was added to the collection in February 2017. The Collection event records contain detailed information on each of 500 samples collected from the Pacific Ocean, including species identification, cruise name and station number, date (dd.mmm.yy) of collection, exact longitude and latitude, number of insects in each sample, and developmental stages. The Specimen analysis records contain elemental concentration data for each sample. There are two sets of specimen analysis records - raw data and derived data. Raw data comprise analyses of 26 elements for the 500 specimens. Derived data comprise concentrations of 7 heavy metals that were pollutants considered to be of potential concern to the marine environment. Detailed information on species, location, etc. are given in Data documentation. The three data tables represent the same set of samples/specimens, linked by identification numbers 1-500, which appear in columns with different labels: "Ref #" (Collection event record), first 3 digits of "SAMPLE" (Specimen analysis records – raw data for 26 elements), and "specimen_ID" (Specimen analysis records - derived data for 7 elements).
