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

open access: yesJournal 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 ...

oceandatr: An R Package to Acquire and Process Geospatial Ocean Data

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
We introduce the oceandatr R package, an interface that provides functions for acquiring and processing marine data sources—including bathymetry, geomorphology, ecological, and human use data—and returns these in several grid‐based formats. We outline uses of oceandatr, such as modeling and spatial analysis, and present two case studies where oceandatr

Little Evidence of Benthic Community Resilience to Bottom Trawling on Seamounts After 15 Years

open access: yesFrontiers in Marine Science, 2019
The resilience and recovery dynamics of deep-sea habitats impacted by bottom trawling are poorly known. This paper reports on a fishing impact recovery comparison based on four towed camera surveys over a 15-year period (2001–2015) on a group of small ...

Exhumed eo‐Alpine High‐Pressure Rocks Fed Campanian Turbidites in Eastern Sardinia

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract This study investigates the detrital record of the early orogenic evolution of the Sardinia‐Calabria system, preserved in Upper Cretaceous arenites exposed in eastern Sardinia. Sardinia and Corsica form a continental block that includes a segment of the Alpine orogen and of its former foreland basin.

The Global Seamount Census [PDF]

open access: yesOceanography, 2010
Seamounts are active or extinct undersea volcanoes with heights exceeding ~ 100 m. They represent a small but significant fraction of the volcanic extrusive budget for oceanic seafloor and their distribution gives information about spatial and temporal ...

Surveys of seamounts in the Southern Indian Ocean during the 37th and 38th Japanese Antarctic Research Expedition in 1995 and 1996

open access: yesAntarctic Record, 1998
Surveys of seamounts in the Southern Indian Ocean were carried out during the 37th and 38th Japanese Antarctic Research Expedition (JARE-37 and JARE-38). Previous uncharted seamounts were identified on board the icebreaker SHIRASE.

Petrogenesis and Tectonic Evolution of Cenozoic Magmatism in the Southernmost Northern Andes: Insights From Zircon Petrochronology

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract This study integrates new zircon U–Pb ages, zircon εHf(t)–δ18O isotopic data, and whole‐rock geochemistry to refine the temporal and spatial framework of magmatism in the southern Northern Andes (SNA) from ∼65 to 6 Ma. The San Lucas, Catamayo, Portachuela, and Gonzanamá batholiths and magmatic suites, along with Late Miocene plutons, display ...

Intraplate Seamounts as a Window into Deep Earth Processes [PDF]

open access: yesOceanography, 2010
Seamounts are windows into the deep Earth that are helping to elucidate various deep Earth processes. For example, thermal and mechanical properties of oceanic lithosphere can be deter-mined from the flexing of oceanic crust caused by the growth of ...

Constraining the Permeability and Outer‐Rise Hydration at the Central America Margin

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Subduction zones are important drivers of Earth's geochemical evolution; the presence of water within the subduction system has substantial implications for geohazards, including the style of seismicity and the volume of magma generated at arc volcanoes.

Bathymetry Prediction With SWOT Gravity Anomaly Using Machine Learning Methods: Paper 1–Model Development

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Only one quarter of the global ocean floor has been directly surveyed; the remaining three quarters are inferred from satellite altimeter‐derived gravity data using techniques developed in the 1990s. These classical methods correlate gravity anomalies with known depths and extrapolate bathymetry in unsounded regions.
