Hydrothermal activity lowers trophic diversity in Antarctic sedimented hydrothermal vents [PDF]

, 2016
Sedimented hydrothermal vents are those in which hydrothermal fluid vents through sediment and are among the least studied deep-sea ecosystems. We present a combination of microbial and biochemical data to assess trophodynamics between and within ...

Temperature Controls on Carbon‐Sulfur Diagenesis in Deep Hydrothermal Subseafloor Sediments

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Carbon mobilization and sulfur transformation play a significant role in deep carbon and sulfur cycling. However, sulfur biogeochemistry and its coupling with carbon and iron cycling remain poorly constrained in hydrothermal sediments. We investigated the effect of temperature on carbon‐sulfur‐iron diagenesis in subsurface sediments (≤370 m ...

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

The 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.

Deep-Sea Cold Seep Campylobacterota: Diversity, Growth, Metabolic Characteristics, and Nutrient Production

Microorganisms
Deep-sea chemosynthetic ecosystems, including cold seeps and hydrothermal vents, are widely spread in global oceans. Campylobacterota are important primary producers in deep-sea hydrothermal vents and serve as a vital food source for local invertebrates.

Geological Study of Active Cold Seeps in the Syn-collision Accretionary Prism Kaoping Slope off SW Taiwan

Terrestrial, Atmospheric and Oceanic Sciences, 2006
Pogonophoran tube worms, elongated pyrite tubes and authigenic carbonate nodules are used to evaluate the occurrence of potential cold seeps in the syn-collision accretionary prism Kaoping Slope off SW Taiwan.

Hydrothermal dolomitisation of a deep‐water bioherm isolated in a non‐dolomitised intraplatform basin within the Norian Dolomia Principale (Southern Alps, northern Italy)

The Depositional Record, Volume 12, Issue 1, February 2026.
We propose that one of the largest known bioconstructions (the Monte Zenone bioherm) in the Southern Alps, northern Italy, and its growth on a tilted and drowned platform block of the Norian Dolomia Principale was controlled by hydrothermal dolomitisation from fault‐controlled fluids during the Late Triassic–Early Jurassic rifting phase. Dolomitisation

Range‐extending fish become competitive dominants under ocean warming but not heatwaves or acidification

Ecology, Volume 107, Issue 2, February 2026.
Abstract Ocean warming is driving species range extensions into cooler regions. The direct physiological influence of warming on species performance can accelerate such extensions into novel ecosystems; however, indirect effects of invader–resident interactions in cooler regions may counter these positive effects.

Sulfide binding characteristics of blood serum in Calyptogena pacifica and Vesicomya gigas [PDF]

, 1994
The sulfide binding characteristics of blood serum were studied in vitro in two deep-sea vesicomyid clams, Calyptogena pacifica and Vesicomya gigas. Both the C. pacifica and the V.
