Topographic Anchoring and the “Silent Period” of Deep‐Water Polynyas in the 90°W–90°E Antarctic Sector

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Antarctic deep‐water polynyas act as critical windows driving deep ocean ventilation, exerting profound impacts on the global thermohaline circulation and biogeochemical cycles. Utilizing high‐resolution satellite remote sensing and ocean reanalysis data from 2003 to 2022, this study identified eight recurring deep‐water polynyas within the ...

Cold-water coral distributions in the drake passage area from towed camera observations--initial interpretations. [PDF]

PLoS ONE, 2011
Seamounts are unique deep-sea features that create habitats thought to have high levels of endemic fauna, productive fisheries and benthic communities vulnerable to anthropogenic impacts.

Dual Role of a Subducted Seamount in Megathrust Rupture Initiation and Rupture Barrier

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Using high‐resolution 3D tomography and a relocated 2010–2022 earthquake catalog, we identify a seamount at 20–25 km depth beneath the Mompiche–Cojimíes region in the coastal forearc of Ecuador. This provides a rare, well‐resolved example of seamount preservation at these depths. The seamount coincides with a low interseismic‐coupling corridor

Anomalous Sediment Consolidation and Alteration From Buried Incoming Plate Seamounts Along the Cascadia Margin

Geochemistry, Geophysics, Geosystems
Oceanic plate seamounts are believed to play an important role in megathrust rupture at subduction zones, although consistent relationships between subducting seamounts and plate interface seismicity patterns are not found.

Bibliometric Analysis of the Status and Trends of Seamounts’ Research and Their Conservation

Diversity
Seamounts are prominent volcanic seafloor features whose morphology affects many ocean processes, sustaining deep-sea communities and providing many ecosystem functions and services.

On the Coherent and Incoherent Characteristics of Semidiurnal Internal Tides Near the Luzon Strait: Influences of Sampling Interval and Observation Duration

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Internal tides (ITs) usually exhibit incoherent characteristics during their propagation. However, estimations of incoherent ITs from different platform (mooring and satellite) observations exhibit discrepancies, partly due to their different sampling intervals and observation durations.

Geomorphology and Age Constraints of Seamounts in the Cabo Verde Archipelago, and Their Relationship to Island Ages and Geodynamic Evolution

Geochemistry, Geophysics, Geosystems
The Cabo Verde Archipelago is related to a mantle plume located close to the rotational pole of the African Plate. It consists of islands and seamounts arranged in a horseshoe‐shaped pattern open to the west, thus forming two volcanic chains, each with a

Ocean Bottom Seismometers Provide Direct Measurements of Pulsed‐Structure and Turbulence of Turbidity Currents Overspilling From a Submarine Channel

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Turbidity currents transport vast amounts of sediment, carbon, and heat along submarine channels, yet their overspill onto channel‐levees and abyssal mixing remain poorly constrained due to lack of direct observations. Ocean‐bottom seismometers (OBS) deployed on the Congo Canyon–Channel levees captured the structure and turbulence of overspill

Lithospheric control on geochemical composition along the Louisville Seamount Chain

Geochemistry, Geophysics, Geosystems, 2011
Major and trace element and Sr, Nd, and Pb isotope data for lavas from 12 seamounts along the western (older) 1500 km section of the Louisville Seamount Chain in the southwest Pacific show remarkably uniform compositions over a ∼30–40 Myr period of ...

Interaction of internal waves with the seafloor on the Namibian shelf (SE Atlantic Ocean): Implications for seafloor geomorphology

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Over geological timescales, internal waves play a significant role in shaping the seafloor morphology. They generate nepheloid layers, slope‐parallel channels and escarpments with erosional surfaces. Abstract The long‐term impact of internal waves on sedimentation and seafloor geomorphology remains poorly constrained.
