Once created, the forms that a user accesses using the majority of the sample types are designed with specific fields an validations associated with the indicated protocols (i.e. NAWQA or NRSA); however, the User-specified Fish (FGEN) and User-specified Invertebrate (IGEN) data entry screens provide a more generalized set of fields to accommodate a wider variety of protocols. As such, the user, after selecting one of these sample types, is required to choose a "Sampling Method Reference" to ensure that the field sampling protocol is known. |
