title: Erratum.
abstract: In the report "Mississippi deltaic wetland survival: sedimentation versus coastal submergence" by R. H. Baumann et al. (8 June 1984, p. 1093), the coordinates for Barataria Bay and for Fourleague Bay were incorrect. They should have been, respectively, 29 degrees 30'N, 90 degrees W, and 29 degrees 20'N, 91 degrees 10'W.
