( Binet and Le Borgne, 1996): DW1% = settled vol. ∗ 14.876 (correlation coefficient, r, of 0.470∗∗, significant at the 1% probability level for a coupled data number, n, of 143) and DW1% = DW10%/0.729 (r = 0.450∗∗; n = 137). In this paper, we use the dry weight obtained either on 1% formalin preserved samples or converted from DW10% or from the settled volume, using the above ratios.
