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 ...

Coseismic Slip and Early Afterslip of the 2024 Hyuganada Earthquake Modulated by a Subducted Seamount

Geophysical Research Letters
Subducted rough topography complicates seismic and aseismic slip behavior. The 2024 M 7.1 Hyuganada earthquake occurred along the megathrust with ridge subduction.

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

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

Seamounts

Seamounts represent crust-mantle activities and are areas of petrological deviations, biodiversity, seismicity and hydrothermal events. An estimated ~50 million tons/year of basalts are required to produce seamounts suggesting intense oceanic volcanism.

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

Unveiling the Faunal Diversity in the Water Column Adjacent to Two Seamounts in the Deep Arabian Sea Using Environmental DNA Metabarcoding

Journal of Marine Science and Engineering
The diversity of organisms inhabiting deep-sea ecosystems, such as seamounts, has hitherto remained under-studied. In this study, we report on the faunal diversity in the water column adjacent to the summit and periphery of two seamounts (SMS2 and SMS3 ...
