Figure 4: SEM images of the seagrass crystals.
From: Direct contribution of the seagrass Thalassia testudinum to lime mud production
SEM images of the seagrass aragonite crystals showing similar size and shape with the sedimentary non-skeletal needles18,19: (a,b) internal crystals within semi-burned leaves; (c,d) view of young CaCO3 deposits on basal leaf fragments of the second youngest leaf; and (e,f) view of the CaCO3 deposits on old leaves. The first two images (a,b) correspond to leaves collected in the reef lagoon of Puerto Morelos in April 2013. The four other images (c–f) correspond to leaves collected in Tulum (Riviera Maya, Mexico) in January 2013.
