Effectiveness of Saturated Coral Aggregate and Shrinkage Reducing Admixture on the Autogenous Shrinkage of Ultrahigh Performance Concrete

open access: yesAdvances in Materials Science and Engineering, 2017
The use of saturated coral aggregate (SCA) as practical replacement of quartz sand has been shown to effectively mitigate the autogenous shrinkage in ultrahigh performance concrete (UHPC).

Aragonite Saturation Horizon Variability Along North Pacific Seamounts and Implications for Deep‐Sea Coral Reefs

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract The 2014 discovery of living deep‐sea coral reefs along the Northwest Hawaiian Islands (NWHI) and lower Emperor Seamount Chain (ESC), despite the North Pacific's shallow aragonite saturation horizon (ASH) and high CaCO3 dissolution rates, underscores the need to understand the local seawater chemistry where these reefs persist. We investigated

Lichen bleaching as a response to long‐term experimental warming in the High Arctic

open access: yesFunctional Ecology, Volume 40, Issue 7, Page 2318-2331, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Lichens are an important component of Arctic ecosystems. Studies have indicated a decline in the abundance of Arctic lichens during recent decades, which is often attributed to competitive pressure from vascular plants.

Linking seaweed farming with coral restoration: Bioremediation boosts early coral survivorship

open access: yesJournal of Applied Ecology, Volume 63, Issue 7, July 2026.
These findings improve our understanding of seaweed cultivation on coral reefs, highlighting the ways in which farmed seaweed can improve water quality and enhance early coral survival. Linking coral restoration with a commercially viable seaweed industry creates a scalable, market‐driven mechanism to overcome costly post‐settlement survival ...

A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1091-1119, June 2026.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

Sedimentation‐driven environmental filtering shapes community assembly of cryptic coralline algae

open access: yesEcosphere, Volume 17, Issue 6, June 2026.
Abstract Community assembly of cryptic crustose coralline algae (CCA) underlies the formation of algal reefs across the global ocean, yet the ecological mechanisms shaping these communities remain poorly understood. Sedimentation has been linked to variation in CCA community structure across the Taoyuan Algal Reef (TAR), the world's largest subtropical

Monotonic triaxial testing and simple modeling of calcareous sand considering the effects of fractal dimension and relative density

open access: yesFrontiers in Marine Science
Calcareous sand from the Nansha Islands, South China Sea, is mainly composed of coral and shell debris, and features irregular particle morphology, abundant intragranular pores, and high particle crushability, which brings considerable geotechnical ...

Experimental study on friction characteristics between stainless steel and saturated dense coral sand

open access: yesResearch on Engineering Structures and Materials
Coral sand is one of the typical subsoils for construction projects on coastal and island regions in Southeast Asia, including Vietnam’s islands. In these regions, many structures are made from stainless steel to withstand the marine environment. Due to the load characteristics, these structures often face stability challenges, such as excessive ...

Experimental study on liquefaction flow characteristics of saturated coral sand considering the influence of particle gradation

open access: yes
Abstract Under seismic loading, saturated coral sand is prone to liquefaction, leading to damage of structures on coral reefs. Due to hydraulic sorting, coral sand in different sites often has varying particle gradations. This study reinterprets liquefiable coral sand as a non-Newtonian fluid and systematically investigates the rheological ...
