Rubble persistence under ocean acidification threatened by …
Findings indicated that increased mechanical bioerosion rates occurred in rubble with lower skeletal density, which is of note considering that corals form lower-density skeletons under OA. These direct and indirect effects of OA on chemical and mechanical framework-altering processes will influence the permanence of this crucial habitat ...
The formation of biogenic reef stone: from coral skeleton to reef rubble
2022年2月20日 · We divided the entire process into three stages: coral skeleton, consolidated sediment, and reef rubble (Fig. 1). 3D skeleton reconstructions of coral samples at each stage were created to reveal the morphology differences (Fig. 2), based on which the lumens of the canal systems were reconstructed to calculate the skeleton-void ratios (Fig. 3 ...
Substrate stabilisation and small structures in coral restoration ...
2020年10月27日 · Rubble on coral reefs can be defined as dead coral skeleton or reef rock pieces that have fractured and been liberated by mechanical or chemical means and are larger in size fraction than sand (>2mm) .
Global Change Biology | Environmental Change Journal - Wiley …
2024年6月11日 · Findings indicated that increased mechanical bioerosion rates occurred in rubble with lower skeletal density, which is of note considering that corals form lower-density skeletons under OA.
The biology and ecology of coral rubble and implications for
2021年9月30日 · This literature review synthesises available knowledge on the biology and ecology of coral rubble. We highlight key methodologies used to sample rubble communities, and the biological and ecological consequences of ongoing habitat degradation from coral to rubble reefs under future scenarios.
2 hidden male skeletons discovered under pile of rubble in …
2023年5月18日 · Archaeologists have discovered two skeletons buried beneath a collapsed wall in Pompeii and think that their deaths were the result of an earthquake that coincided with Mount Vesuvius' deadly ...
Structural changes in carbonate skeletons during reef rubble …
We divided the entire process into three stages: coral skeleton, consolidated sediment, and reef rubble (Fig. 1). 3D skeleton reconstructions of coral samples at each stage were created to...
The compressive strength of coral skeletons increased from 4–7 MPa to more than 40 MPa during reef rubble formation, and decreased to 1–2.5 MPa after bioerosion by barnacles. This work provides structural information for diagenetic changes, insight into barnacle erosion in coral skeletons, and extends our understanding of mechanical ...
Canal reconstruction reveals the changes in the skeleton-void …
We divided the entire process into three stages: coral skeleton, consolidated sediment, and reef rubble (Fig. 1). 3D skeleton reconstructions of coral samples at each stage were created to...
Ice rubble behaviour and strength: Part I. Review of testing and ...
2005年2月1日 · The primary failure mode associated with initial breakage of rubble skeleton is found to dominate overall rubble strength in punch tests. Scaling of ice rubble is touched upon and a summary of scaled rubble properties is presented. The average c / t value was found to be around 20 kPa/m derived both from the laboratory and the in-situ tests.
