Geophysical Constraints on the Relationship Between Seamount Subduction, Slow Slip, and Tremor at the North Hikurangi Subduction Zone, New Zealand

Geophysical Research Letters, 2018
We use a prestack depth migration reflection image and magnetic anomaly data across the northern Hikurangi subduction zone, New Zealand, to constrain plate boundary structure and geometry of a subducting seamount in a region of shallow slow slip and ...

Mantle Dynamic Topography of the Fringing Oceanic Basins of Antarctica

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Dynamic mantle processes are known to influence oceanic basins with implications for ocean circulation and climate. This study exploits an interdisciplinary approach to probe present‐day mantle and lithosphere beneath Antarctica's fringing oceanic basins to better understand sub‐crustal processes and implications for the continental realm.

Deep-sea coral distribution on seamounts, oceanic islands, and continental slopes in the Northeast Atlantic [PDF]

, 2007
A database of deep-water (\u3e 200 m) antipatharians, scleractinians, and gorgonians has been assembled for the NE Atlantic to determine what their distribution and diversity was before coral habitats became heavily impacted by bottom fishing gear ...

Contemporary Foraging of the Hawaiian Monk Seal as a Retrospective Lens for Commercial Fishing and Its Relevance to Ecosystem‐Based Fishery Management

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT This retrospective analysis explores how historical fishing activity (1948–2009) at French Frigate Shoals (FFS) can be examined in relation to the foraging ecology of Hawaiian monk seals. We bring together fisheries catch records, monk seal demographic information, and ecological studies on prey, competitors, and predators to evaluate ...

Louisville Seamount Chain: Petrogenetic processes and geochemical evolution of the mantle source

Geochemistry, Geophysics, Geosystems, 2014
The Louisville Seamount Chain is a ∼4300 km long chain of submarine volcanoes in the southwestern Pacific that spans an age range comparable to that of the Hawaiian‐Emperor chain and is commonly thought to represent a hot spot track.

First record of an Odontaspidid shark in Ascension Island waters [PDF]

, 2019
The occurrence of the poorly understood shark species Odontapsis ferox is reported at an oceanic seamount in the central south Atlantic, within the Exclusive Economic Zone of Ascension Island.

Golden Gate Bridge, as Always? Eliciting Prototypical Places From Autoregressive Large Language Models via Category Production

Transactions in GIS, Volume 30, Issue 2, April 2026.
ABSTRACT Among the various theories of categorization, Eleanor Rosch's prototype theory stands out as both influential and contested. In contrast to the classical theory of concepts, prototype theory posits that humans conceptualize the world using category structures where exemplars vary in their degree of membership.

Behavior and Ecology of Silky Sharks Around the Chagos Archipelago and Evidence of Indian Ocean Wide Movement

Frontiers in Marine Science, 2020
Silky sharks (Carcharhinus falciformis) represent a major component of global shark catch, both directly and as bycatch, and populations are declining as a result.

Trace element geochemistry of peridotites from the Izu-Bonin-Mariana Forearc, Leg 125

, 1992
Trace element analyses (first-series transition elements, Ti, Rb, Sr, Zr, Y, Nb, and REE) were carried out on whole rocks and minerals from 10 peridotite samples from both Conical Seamount in the Mariana forearc and Torishima Forearc Seamount in the Izu ...

New Phoenix Magnetic Anomaly Data Confirms Global Nature of Jurassic Quiet Zone and Provides Insight Into Early Pacific Spreading

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract We demonstrate the presence of the oldest identifiable marine magnetic anomalies in the Phoenix lineations of the western Pacific based on careful assessment of new data. Recently acquired sea surface magnetic anomalies and multichannel seismic profiles confirm magnetic signals recorded within the Middle‐Jurassic to Early Cretaceous basement ...
