Methodology: Archimedes principle

ID: 3

Description:

Weighing coral skeleton first in air and then suspended briefly from an analytic balance into freshwater (Graus & MacIntyre 1982; Hughes 1987; Madin et al. 2008). Skeletal volume was estimated as air weight divided by density.

Used for traits:

• Skeletal density
• Skeletal micro-density
