Abstract/Description:
This research explores the instantaneous mechanical behavior of the skeleton of the critically endangered staghorn coral Acropora cervicornis. Both bleached and sanded skeletons were used in this experiment. The Raman spectroscopy test showed that there was no significant change in the Raman shift between the three branches tested. The shifts were nearly identical to Raman shifts of calcium carbonate. Vickers hardness test found that 1 Bleached had the average hardness of 3.44 GPa with a standard deviation of 0.12 GPa. The sanded sample also had a similar value of 3.54 GPa with a standard deviation of 0.13 GPa. Samples from 2 Bleached had a hardness value that was significantly lower at only 2.68 GPa with a standard deviation of 0.37 GPa. The axial compressive stress test determined that the average strength for the bleached samples was 18.98 MPa and for the sanded, 29.16 MPa. This information can be used to assist in the restoration of this species.
