Abundant interactions and feedbacks between aquatic deoxygenation and the other planetary boundaries suggest “unsafe” levels of oxygen loss with far‐reaching impacts

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Oxygen is critical for nearly all life on Earth, including aquatic species that breathe dissolved oxygen in both freshwater and marine systems. The rapid, global, and anthropogenic loss of dissolved oxygen known as “aquatic deoxygenation” threatens life in these environments, the human communities that depend on them, and Earth system ...

Different Ferromanganese Concretion Morphologies Host Distinct Microbial Communities and Metal Accumulation Patterns in the Baltic Sea

Environmental Microbiology, Volume 28, Issue 7, July 2026.
We investigated how microbes influence the metal accumulation and release in Fe‐Mn concretions from the Gulf of Finland using microcosm incubation experiments. We studied three main concretion morphotypes: crust, discoidal, and spheroidal. Microbes enhanced metal accumulation in discoidal and spheroidal morphotypes.

Multi‐Omic Assessment of Microbial Communities and Their Polyketide Biosynthetic Potential Across Abyssal Sediments

Environmental Microbiology, Volume 28, Issue 5, May 2026.
Abyssal sediments were assessed for taxonomic diversity and polyketide biosynthetic potential and compared to metagenomic and metabolomic assessments of the same sediments. Biodiversity differences were documented across biogeochemical regimes with the results providing baseline awareness of what might be lost should deep‐sea microbiomes be disrupted ...

Quantification of rheological parameters in deep‐sea mining plumes

Deep Underground Science and Engineering, Volume 5, Issue 1, Page 250-265, March 2026.
This study explores the variations in rheological properties observed during the propagation of deep‐sea mining plumes, utilizing rheological test data obtained from kaolin clay plumes. Subsequently, taking into account the differences in sediment properties, the effects of clay content and clay mineral composition on the rheological parameters of ...

Using Habitat Classification to Assess Representativity of a Protected Area Network in a Large, Data-Poor Area Targeted for Deep-Sea Mining

Frontiers in Marine Science, 2020
Extractive activities in the ocean are expanding into the vast, poorly studied deep sea, with the consequence that environmental management decisions must be made for data-poor seafloor regions.

From Quarries to Urban Construction Sites: Middle‐Late Mesozoic Limestones in the Public Architecture of Roman Verona, Italy

Geoarchaeology, Volume 41, Issue 1, January/February 2026.
ABSTRACT Numerous buildings, monuments, and infrastructural works in Verona were constructed during the Roman period using stone, a material abundantly available from quarrying areas located relatively close to the city. Petrographic investigations conducted by Transmitted Polarized Light Optical Microscopy (TPL‐OM) and complemented by colorimetric ...

Seafloor surficial sediment variability across the abyssal plains of the central and eastern pacific ocean

Frontiers in Earth Science
Abyssal plains lie at water depths of 3,000–6,000 m and account for 84.7% of the global ocean seafloor. This vast landsystem is believed to be one of the major reservoirs of biodiversity within the deep-sea.
