Untargeted Metabolomics Reveals Seasonal and Tissue‐Specific Metabolic Shifts in Holothuria cinerascens

open access: yesChemistry &Biodiversity, Volume 23, Issue 2, February 2026.
Untargeted metabolic profiling of three body tissues from Holothuria cinerascens in South Africa using 1H‐NMR and UPLC–QTOF–MS revealed distinct tissue‐specific and seasonal metabolic variations, with the body wall and gut/mesentery exhibiting high metabolite diversity.

Whitings in the Red Sea

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
We present the first documentation of whitings in the Red Sea, observed in a lagoonal environment. These events are linked to cascading offshore dense waters that liberate trapped sea floor nutrients, triggering algal blooms and elevating alkalinity, which is buffered by direct CaCO3 precipitation—contributing to the accumulation of aragonite mud in ...

Carbonate sedimentology: An evolved discipline

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
Abstract Although admired and examined since antiquity, carbonate sediment and rock research really began with Charles Darwin who, during a discovery phase, studied, documented and interpreted their nature in the mid‐19th century. The modern discipline, however, really began after World War II and evolved in two distinct phases.

A critical role of heterotrophic bacteria in early diagenesis of carbonates through exopolymer degradation and calcium release

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
Exopolymeric substances (EPS) produced in the photic zone and surface sediments sequester calcium. Below the sediment surface, heterotrophic bacteria degrade EPS, releasing calcium resulting in carbonate precipitation. This process, which continues for millennia deep in the core, is an important sink for atmospheric carbon dioxide.
