Appendix 2. MetadataThe data documentation approach outlined here is based on the Federal Geospatial Data Committee (FGDC) standard and has been selected to meet the needs of the Southern California Marine Monitoring Standard Data Transfer Formats, developed through the Regional Water Control Board and regional sampling Information Management Committee participants. All mandatory elements of the FGDC standard are included. In addition, further elements, identified in the standard as mandatory if applicable, are required. Bolded elements represent special applications of metadata agreed upon by the Information Management committee. These elements, indicated by the words “Standard Data Exchange Format Requirements”, specify a prescribed reporting value (either numeric or textual). Finally, elements of the Biological Data Profile, referenced by the preface “BDP”, are included. All required elements have their section number underlined. The metadata are used to document information about the dataset. Documentation should include all information about Event Types, which include Sediment Grabs, Trawl Assemblage, Bioaccumulation, Microbiology Station Occupation, Water Quality Casts, and the tables that are generated from the Event Type. For example, grab event metadata should include information about the sediment chemistry table and benthic infaunal abundance table, as well as the actual grab event table.
