Kogia Records in Brazilian Equatorial and Southwestern Atlantic Oceans

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The pygmy (Kogia breviceps) and dwarf (Kogia sima) sperm whales are cryptic cetaceans characterized by inconspicuous surfacing behavior, small group sizes, and deep‐diving habits, making visual detection particularly challenging. Here, we present the first broad‐scale passive acoustic monitoring (PAM) assessment of Kogia spp.

Unprecedented Open‐Ocean Polynya in Breid Bay, East Antarctica in Winter 2024

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract We document an unprecedented winter open‐ocean polynya in the Breid Bay, on 4 August 2024, attaining a maximum area of 89,121 km2. Prior to opening, sea‐ice concentration declined from ∼96% in early July to below 25% by 30 July 2024, indicating substantial preconditioning of the winter ice cover.

New England Coral Canyons and Seamounts [PDF]

, 2015
Just 150 miles off the coast of Cape Cod lie some of our country's greatest marine treasures. Hidden beneath thousands of feet of ocean, where the continental shelf drops off to the pitch-black abyss of the deep Atlantic Ocean, five massive canyons ...

Structural Heterogeneity Shapes Segmentation of Megathrust Earthquakes and Volcanism in Central America

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The mechanisms underlying the patchy distribution of forearc megathrust earthquakes and arc volcanoes in subduction zones remain poorly understood. Here we present a high‐resolution seismic tomographic model of the Central American subduction zone, derived from a joint inversion of local body‐wave and teleseismic Rayleigh‐wave data.

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 ...

Generation and Preservation of Submarine Terraces: Insights From Records Imprinted on the Topography of Dokdo Volcano

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Marine terraces archive sea‐level and tectonic history, yet their relationship to individual highstands remains contentious. While most studies focus on subaerial terraces in uplifting settings, submerged terraces in subsiding settings are less explored. We develop a 1‐D wave‐erosion model and apply it to Dokdo — a subsiding volcanic island in

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

Frontiers 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 ...

3D Subduction Interface Model for the Hikurangi Margin, New Zealand: Implications for Slow Slip Events

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract We present a new 3D Hikurangi subduction interface model by using an implicit modeling approach that integrates seismic‐reflection profiles, relocated hypocenters, focal mechanism orientations, and tomographic interpretations. The model reveals along‐strike transitions in slow slip events (SSEs) that correlate with subduction interface ...

The Global Seamount Census [PDF]

Oceanography, 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

Antarctic 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.
