Aragonite-calcite seas--quantifying the gray area
, 2015 Oscillations between the dominance of aragonite and calcite in abiotic marine CaCO3 precipitates throughout Earth history are closely coupled with the evolution of Earth’s seawater composition and represent the environmental context in which organisms ...

SPE Polymers, Volume 7, Issue 4, October 2026.Bio‐derived and commercial CaCO3 reinforced laboratory‐reprocessed polypropylene composites were fabricated and characterized, demonstrating improved stiffness and thermal stability while maintaining acceptable processability. ABSTRACT This study investigates laboratory‐reprocessed polypropylene (rPP)‐based composites reinforced with calcium carbonate (

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 725-752, October/December 2026.ABSTRACT The McMurdo Dry Valleys, the largest ice‐free region in Antarctica, are home to a cold‐desert hydrologic system of glaciers, snowbanks, streams, and lakes. Freshwater is also stored as dead glacial ice, which is poorly constrained in terms of ion concentrations and interactions with both in situ and overlying sediments.

Biaxial calcite inverted from aragonite
, 1967 We have recently extended the phase relationships involving a liquid phase in the system CaO-CO_2-H_2O from 4 kilobars pressure (Wyllie and Tuttle, 1960; Wyllie and Raynor, 1965) to 40 kilobars pressure (to be published).

Diagenetic evolution of some modern and ancient cold seep-carbonates from East Coast Basin, New Zealand. [PDF]
, 2009 Cold seep-carbonates are the microbially mediated by-products of the anaerobic oxidation of methane (AOM) at seafloor cold seeps, and are widespread about modern continental margins and in the geologic record.

Global Biogeochemical Cycles, Volume 40, Issue 10, October 2026.Abstract Coral reefs are increasingly threatened by local and global stressors. Traditional visual reef monitoring methods are time‐intensive and provide only a snapshot of reef condition. Recent efforts aim to measure reef metabolism, or the balance of net community production (NCP) and net community calcification (NCC), as coral reef carbonate ...

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.This study investigates whether tissue fusion between adult corals enables transmission of heat‐evolved (HE) symbionts. After ~50 days of fusion to a donor, HE symbionts were detected in chemically bleached Galaxea fascicularis recipients. Fusion also accelerated post‐bleaching recovery.

Conservation Biology, Volume 40, Issue 5, October 2026.Abstract Over the past decades, climate change has emerged as a major threat to global biodiversity, negatively affecting the integrity and functioning of ecosystems and the benefits they provide to people. To mitigate these impacts, it is essential to identify climate refugia that support the persistence of the structure and function of reef ...

Sedimentology, Volume 73, Issue 6, Page 2120-2142, October 2026.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
