... to Motai et al . (2012) , we discovered nanosized granular crystals in the coral skeletal areas consisting of needle-like aragonite. In this study, we identify these nanosized granular crystals, and describe their characteristics and origin. The skeleton of the massive coral Porites lobata used...

...THOMAS PICHLER; JEFFREY M. HEIKOOP; MICHAEL J. RISK; JAN VEIZER; IAIN L. CAMPBELL Abstract The coral reef in Tutum Bay, Ambitle Island, Papua New Guinea, is exposed to the vigorous discharge of hydrothermal fluids (up to 98°C). This study investigates eight Porites lobata samples that were...

The four dominant coral species record ed are the delicate finger coral Porites compressa , a low-energy species; Pocillopora meandrina and Montipora sp., both of which are medium energy and more robust; and Porites lobata...

... were selected to quantify observed differences in adjacent zones (e.g., along channel walls). Living corals were identified to the species level and their growth form recorded (e.g., Porites lobata encrusting). Species diversity (H′ c ; Shannon and Weaver 1948 ) was calculated from transect data...
