Abstract The purpose of the data dictionary is to provide information pertaining to the contents and structure of the Eastern Lakes Survey-Phase II (ELS-II) chemistry database. The data dictionary does not describe the design, protocols, or findings of the study, which are described in Herlihy et al. (1991). Section 2 describes the overall design and development of the ELS-II database. Section 3 is a summary of data quality. Section 4 identifies all variables in the database, and Section 5 provides detailed definitions of the variables. Section 6 describes 'tags' and 'flags' which are two types of data qualifiers.
