Mesophotic octocoral larval settlement preferences and behaviors

Restoration Ecology, EarlyView.
Abstract Introduction Lab‐based coral reproduction is advancing restoration efforts to support coral populations injured by the 2010 Deepwater Horizon oil spill. Objectives This study aimed to answer foundational questions concerning coral spawning and larval settlement that need to be resolved for these mesophotic and deep‐sea coral species before ...

Antifouling capacity of substrate materials and their effects on settlement and post‐settlement survival of Acropora palmata and Orbicella faveolata

Restoration Ecology, EarlyView.
Abstract Introduction In coral reef restoration, sexual reproduction is a key methodology to enhance coral population recovery. However, post‐settlement survival remains a major bottleneck, as spat are particularly vulnerable to competition with fouling organisms.

The effects of bioturbation on porewater chemistry and early marine diagenesis: Evidence from a modern intertidal zone in Abu Dhabi, U.A.E.

Sedimentology, EarlyView.
ABSTRACT Early marine carbonate cements generally form in CaCO3‐supersaturated seawater at the seabed or shallow burial depths, resulting in syn‐sedimentary cemented firmgrounds and hardgrounds. The processes controlling early marine diagenesis are complex, particularly in coastal environments where geochemistry is influenced by different water sources

Diagenetic controls on porosity evolution and pore type organisation in microporous carbonate rocks: Evidence for mesogenetic porosity formation

Sedimentology, EarlyView.
ABSTRACT Microporous carbonate rocks typically record complex diagenetic histories driven by microbial activity and fluid interactions within multiple diagenetic environments. The relative roles of meteoric and burial diagenetic processes in pore evolution remain debated, particularly within Cretaceous carbonate systems of the Middle East, as does the ...

Remineralisation of Reverse Osmosis (RO) Water Using Synthetic Aragonite

Water and Environment Journal, EarlyView.
ABSTRACT Reverse osmosis (RO) treated water often requires remineralisation to restore Ca2+ ions, hardness and alkalinity, particularly for potable water. This study compares the dissolution characteristics of two forms of calcium carbonate, aragonite and calcite.

Biomineral crystallographic preferred orientation in Solenogastres molluscs (Aplacophora) is controlled by organic templating

Scientific Reports
Aplacophoran molluscs are shell-less and have a worm-like body which is covered by biomineralized sclerites. We investigated sclerite crystallography and the sclerite mosaic of the Solenogastres species Dorymenia sarsii, Anamenia gorgonophila, and ...

A Late Quaternary record of highstand shedding from an isolated carbonate platform (Juan de Nova, southern Indian Ocean)

The Depositional Record, 2019
A 27 m core collected on the sea floor near Juan de Nova island at 1,909 m depth in the SW Indian Ocean preserves a high‐resolution record of carbonate sediment export to the deep sea over the past 1 Myr.

Effects of temperature, pH and calcium-to-carbonate ratio on the calcium carbonate polymorphs

Discover Civil Engineering
The precipitation of calcium carbonate (CaCO3) polymorphs (calcite, vaterite, and aragonite) plays a crucial role in tailoring the physicochemical properties of construction materials during mineral carbonation.

Mineralogical characteristics of surface sediment in Sulaibikhat Bay, Kuwait

Kuwait Journal of Science, 2013
Surface sediment samples were collected from 35 locations in Sulaibikhat Bay, Kuwait. Grain sizes, total organic carbon (TOC), carbonate and mineralogical data were determined.

Ocean Acidification in the California Current System [PDF]

Oceanography, 2009
Eastern boundary upwelling systems (EBUS) are naturally more acidic than most of the rest of the surface ocean. Observations of EBUS already show pH values and saturation states with regard to the carbonate mineral aragonite that are as low as those ...
