Along the Benthic to Holoplanktonic Continuum: Seafloor Affinity Increases Distance‐Decay Rates Among Abyssal Communities

Global Ecology and Biogeography, Volume 35, Issue 8, August 2026.
ABSTRACT Aim Marine species ranges are often large, contributing to relatively high community similarity over space, with decreased ranges expected among taxa that have lower dispersal and/or higher substrate requirements. We tested for a weakening of biogeographic structuring among dispersing abyssal taxa along the benthic to holoplanktonic habitat ...

Why Are Most Fish Populations Genetically Homogeneous Along the Southwestern Atlantic Coast? The Role of Life History Traits in Shaping Genetic Patterns

Journal of Biogeography, Volume 53, Issue 8, August 2026.
ABSTRACT Aim Investigate patterns of population genetic structure in Southwestern Atlantic marine fishes and evaluate how geographic range, habitat diversity, and evolutionary history shape population connectivity. Location Southwestern Atlantic, including the Caribbean, Brazilian coast, and Patagonian region, between 0°59′ N and 40°16′ S.

High‐Resolution Imaging of a Distant M6 Intermediate‐Depth Earthquake Using Ocean‐Bottom DAS and Seismic Network

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Distributed Acoustic Sensing (DAS) provides dense, wide‐aperture observations potentially ideal for imaging earthquake rupture processes. By combining data from a ∼450 km‐long seafloor DAS array offshore Chile and a conventional seismic network, we image an Mw 6.0 intermediate‐depth earthquake ∼400 km away in Argentina, achieving km‐scale ...

Tracing the Persistence and Role of Deep‐Sea Iron Sources in the Pacific Ocean Over the Last 23 Million Years

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Iron (Fe) plays a critical role in marine productivity and the global carbon cycle. The relative contribution of different Fe sources such as atmospheric aerosols, sediment dissolution, and submarine hydrothermalism influences the distribution and biogeochemical cycling of Fe in the ocean. However, distinguishing these Fe sources over time has

Diversity and potential host-interactions of viruses inhabiting deep-sea seamount sediments

Nature Communications
Seamounts are globally distributed across the oceans and form one of the major oceanic biomes. Here, we utilized combined analyses of bulk metagenome and virome to study viral communities in seamount sediments in the western Pacific Ocean.

Subsurface Production of Marine Derived Bacterial Tetraether Lipids: Implications for Paleoceanographic Reconstruction

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Branched glycerol dialkyl glycerol tetraethers (brGDGTs) are widely used as paleoclimate proxies on land, yet their origin in marine environments remains incompletely constrained. Here, we analyze suspended particulate matter collected from five depths at an open‐ocean station in the northern South China Sea and provide depth‐resolved evidence

The Influence of Seamounts on the Enrichment of Rare Earth Elements in Sediments—A Case Study of the Marcus-Wake Seamounts in the Western Pacific Ocean

Journal of Marine Science and Engineering
Deep-sea sediments enriched in rare earth elements and yttrium (REY-rich sediments) are widely distributed on the deep-sea floor, and their formation mechanism remains elusive.

The Complete Life Cycle of Dark Spot NDS‐2018 on Neptune

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The Hubble Space Telescope collected imaging data spanning the full lifetime of Neptune's dark spot NDS‐2018, which is the sixth large, persistent dark spot seen in the planet's atmosphere. Neptune's dark spots are thought to be anticyclonic vortices, although internal flows have never been directly measured to confirm their rotation. Previous

Turbulent Mixing and Dissipation Around Rough Seamounts

Geophysical Research Letters
Seamounts are critical components of the global ocean energy budget, contributing significantly to turbulent dissipation through their interaction with large‐scale flows. However, most previous numerical investigations used smoothed bathymetry that omits
