Origins of Earth's most powerful ocean current revealed

Phys.org: Earth science - Mon, 04/06/2026 - 19:00
It transports far more than 100 times as much water as all of the Earth's rivers combined: The Antarctic Circumpolar Current rushes around the southern continent unhindered by land masses and is therefore a fundamental component of the climate system. In a recent study published in the journal Proceedings of the National Academy of Sciences, a research team led by the Alfred Wegener Institute describes how and when this mighty ring current developed in Earth's history.

Robotic floats uncover hidden ocean chemistry in low-oxygen zones

Scientists have found a new way to detect subtle chemical signatures in seawater, revealing previously invisible details about the ocean's chemistry from data continuously collected by thousands of autonomous robotic floats drifting across the seas.

3D root model captures mangroves' capacity to protect coastal communities from storm waves

Phys.org: Earth science - Fri, 04/03/2026 - 16:20
Mangrove forests are natural wonders that protect coastal areas, particularly in tropical and subtropical regions. They are able to dissipate wave energy and limit flooding, which can even mitigate tsunamis and coastal inundations during tropical cyclones. For this reason, mangroves are attracting attention as Nature-based Solutions, or NbS: natural infrastructure with the potential to enhance coastal resilience in an environmentally friendly way.

P-wave velocity and azimuthal anisotropy of the crust and uppermost mantle beneath Northeast China

Geophysical Journal International - Fri, 04/03/2026 - 00:00
SummaryNortheast China hosts one of the largest intraplate Cenozoic volcanic provinces and has experienced multiple collisions during the Paleozoic, extension during the Late Jurassic–Early Cretaceous and compression during the Pliocene. Tectonism in Northeast China has been largely controlled by subduction of the western Pacific plate since the Mesozoic and is typically characterized by the formation of multiple intraplate volcanic groups and sedimentary basins. The mechanism underlying the tectonism in this area, particularly the origin of the Cenozoic intraplate volcanoes and the evolution of the supersedimentary Songliao basin, remains controversial. To address these issues, we conducted seismic tomography to image the P-wave velocity and azimuthal anisotropy of the crust and uppermost mantle beneath Northeast China. In this study, we adopt an eikonal equation-based traveltime tomography method to invert high-quality P-wave first arrivals. We manually pick 21,006 P-wave first arrivals from 890 regional earthquakes recorded by 426 broadband seismic stations. Four prominent features are revealed by tomographic inversion. First, the results reveal a significant low-velocity anomaly in the uppermost mantle of the Changbaishan volcano and strong azimuthal anisotropy with E–W-oriented fast velocity directions distributed along the low-velocity anomaly. This feature indicates horizontal flow in the uppermost mantle beneath the Changbaishan volcano. Second, a prominent low-velocity anomaly is present in the mid-lower crust below the Changbaishan volcano, implying the presence of a magma chamber. Third, the crust of the Wudalianchi volcano is characterized by a nearly normal velocity structure and strong azimuthal anisotropy with N–S-oriented fast velocity directions, suggesting that magmatic activity has little effect on the crustal structure. Fourth, a widespread distinct low-velocity anomaly in the mid-lower crust beneath the Songliao basin reflects the mechanically weak properties of the mid-lower crust.

Paleomagnetic constraints on Late Miocene kinematic adjustment in the western South Tianshan foreland

Geophysical Journal International - Fri, 04/03/2026 - 00:00
SummaryThe western South Tianshan foreland records late Cenozoic deformation associated with the India-Eurasia collision, yet the timing and nature of Miocene kinematic changes remain poorly constrained. Here we present new magnetostratigraphic, paleomagnetic, and anisotropy of magnetic susceptibility (AMS) data from a ~12–6 Ma succession in the western Keping fold-and-thrust belt (FTB). Paleomagnetic results from 39 site-mean directions reveal small-magnitude vertical-axis rotations since ~12 Ma, characterized by two distinct rotational phases: an earlier clockwise (CW) rotation (potentially reaching ~8-9° when evaluated relative to a younger counterclockwise (CCW) background) prior to ~10 Ma, followed by a persistent but minor CCW rotation (~4°) from ~10 to 6 Ma. Although the magnitude of rotation is limited, this pattern indicates a subtle change in rotational behavior. Importantly, the persistence of the CCW rotation throughout the younger interval suggests that the observed rotations were not fully acquired during deposition, but may have been modified by deformation younger than ~6 Ma. AMS fabrics show corresponding variations in magnetic anisotropy, indicating a shift from relatively organized tectonic strain to more distributed deformation. We interpret these results as reflecting progressive basinward propagation of thrusting in the South Tianshan foreland, with rotation-related deformation occurring during a relatively late stage. Overall, the dataset highlights the limited magnitude and young timing of rotational deformation within the Keping FTB.

Characterization of the crust and uppermost mantle beneath the São Francisco Craton (Brazil) and adjacent areas from Rayleigh wave tomography

Geophysical Journal International - Fri, 04/03/2026 - 00:00
SummaryThis study investigates the crustal and uppermost mantle architecture beneath the São Francisco Craton (SFC), which constitutes the core of the broader São Francisco Paleocontinent (SFP), and its surrounding tectonic provinces through Rayleigh wave tomography, integrating ambient-noise (periods of 6–50 s) and earthquake-derived (periods of 9–180 s) dispersion curves. Two-dimensional phase and group velocity maps were regionalized using adaptive parameterization, with the resolution assessed from checkerboard tests. A pseudo-3D shear-wave velocity (VS) model was generated down to 70 km depth, from which crustal thickness was also derived using the maximum velocity gradient method. Results at shallow depths (2–10 km) identify the Paraná, Parnaíba, and Tucano–Jatobá basins as low-velocity anomalies, while the São Franciscan Basin is not fully resolved because its reduced thickness falls below the model’s resolution limit, despite its broad surface extent. In the middle-to-lower crust (20–40 km) inside SFC, a low VS corridor characterizes the Paramirim Aulacogen, highlighting the role of inherited rift structures and subsequent thermal reworking within the cratonic interior. At greater depths (60–70 km), the Borborema Province exhibits low velocities that contrast with the high velocities of the stable SFC root. The Moho map derived from tomography indicates crustal thickening beneath the Paraná and Parnaíba basins and the Brasília Belt, in good agreement with receiver-function estimates. Overall, the VS anomalies and Moho geometry in the regions neighboring the SFC reveal high-velocity corridors with relatively thin crust (32-36 km) extending across the Tocantins, Mantiqueira, and Borborema provinces, and projecting northwestward beneath the Parnaíba Basin. These results demonstrate that the boundaries of the São Francisco Paleocontinent extend significantly beyond its exposed surface limits within the crust and uppermost mantle. These boundaries are clearly discernible mainly at lower crustal depths and likely reach the upper crust. Furthermore, marginal deformations are primarily restricted to shallower levels of the crust, suggesting the preservation of a mechanically strong and continuous cratonic foundation beneath the surrounding orogenic belts and intracratonic basins. The main exception occurs along the southwestern margin, where the absence of a clear seismic boundary between the SFP and the Paranapanema Block suggests deep lithospheric integration or a boundary too narrow to be resolved by the present station geometry.
