BSAF Database Descriptive Statistics

Data from the ERDC-WES BSAF Database


These data represent a subset of the BSAF database. Only records with a valid mean, (n) and a calculated error were used for the generation of this table. Individual records that did not provide a mean are NOT used. (Additional Information)

benthic* = "benthicaly-coupled". This groups invertebrates and bottom-feeding fish using whole organism, muscle, or filet values only
moll/poly** refers to molluscs and polychaetes grouped together

Explanations of the column headers:

Group Description = Type of organisms grouped together for calculations (See below), Grand Mean = Mean BSAF calculation of a group of means, n = number of records used for calculation, RMSE = Root Mean Square Error of the Grand Mean, Range = Range of means for these data, Max = Maximum mean value for these data, Min = Minimum mean value for these data,

Explanation of Group Descriptions:
01.) All mean BSAF data for every organism/tissue/habitat.
02.) All mean BSAF data for every organism/tissue/habitat collected during field studies.
