The Longhurst Biogeochemical Province (LBGC_Province) referred to in the database
is more fully explained by a combination map and table. The full
reference for the Longhurst et al. (1995) paper cited in the parameter
list below, is given in the list of references for this project. The reference
document also gives full listings for all references cited in the data set itself.
