Megafaunal Ecology of the Western Clarion Clipperton Zone

Frontiers in Marine Science, 2021
The Clarion Clipperton Zone (CCZ) is a vast area of the central Pacific Ocean where the abyssal seabed is a focus for future polymetallic nodule mining.

The theory of island biogeography and the stability of oceanic reef fish communities

Journal of Fish Biology, EarlyView.
Abstract Reef fish assemblages on oceanic islands offer valuable insights into ecological and evolutionary processes, yet their temporal dynamics remain poorly understood. This study evaluates the theory of island biogeography (TIB) with long‐term ecological monitoring to assess how island area, isolation from nearest reef and distance from mainland ...

Description of four new species of marine macroalgae from Rangitāhua, New Zealand

Phycological Research, EarlyView.
ABSTRACT Four species of marine macroalgae are described from Rangitāhua, the northern islands of the New Zealand archipelago. The flora of this region has been considered to have its strongest affinities with other warm‐water regions of the Pacific and Indian Oceans, with very low levels of endemism.

Seamounts – characteristics, formation, mineral deposits and biodiversity

Geologica Acta, 2012
Seamounts represent crust-mantle activities and are areas of petrological deviations, biodiversity, seismicity and hydrothermal events. An estimated ~50 million tons/year of basalts are required to produce seamounts suggesting intense oceanic volcanism.

Geographical distribution and driving force of micro-eukaryotes in the seamount sediments along the island arc of the Yap and Mariana trenches

Microbiology Spectrum, 2023
The specific topographic characteristics and complex hydrodynamics of seamounts could directly or indirectly affect the distribution and trophic status of microbes. However, little is known about the distribution patterns and associated driving forces of

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 ...

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 ...

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

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.

Monogenetic Near‐Island Seamounts in the Galápagos Archipelago

Geochemistry, Geophysics, Geosystems, 2020
Rarely have small seamounts on the flanks of hotspot derived ocean‐island volcanoes been the targets of sampling, due to sparse high‐resolution mapping near ocean islands.
