Calculation of subcutaneous fat for seal WS12-22 using traditional truncated cones with circular cross-sections.

Radius outer cone = Girth/2π; Radius difference = base − roof of cone; Straight Length = sqrt(Curvilinear Length2 − Radius Difference2); Radius inner cone = Radius outer cone – (2 × Blubber Depth); Outer/Inner Cone Volume = (1/3)π × [(Radius Outer/Inner1)2 + (Radius Outer/Inner1 × Radius Outer/Inner2) + (Radius Outer/Inner2)2]; Blubber Volume = Outer Cone Volume − Inner Cone Volume; Mass Conversions: Core Mass = Core Volume × 1.1; Blubber Mass = Blubber Volume × 0.94; Total Body Mass = Core Mass + Blubber Mass.
