Attribute_Label: Blubber_thickness
Attribute_Definition:
Thickness of the blubber, in millimeters. Blubber depth was measured ventrally at the sternum when possible (Fay 1982, Popov 1981).

The data records do not indicate whether a measurement was taken ventrally or dorsally. Blank cells indicate that the blubber thickness was not recorded.
