Seamounts: Deep-Ocean Laboratories of Faunal Connectivity, Evolution, and Endemism [PDF]

open access: yesOceanography, 2010
Seamount systems that are geographically, hydrographically, topographically, and/or genetically “isolated” are likely to have developed highly endemic taxa and ecosystems.

Palladium, platinum, and gold distribution in serpentinite seamounts in the Mariana and Izu-Bonin forearcs: evidence from Leg 125 fluids and serpentinites

open access: yes, 1992
Palladium, platinum, and gold were analyzed for 20 interstitial water samples from Leg 125. No Pd or Pt was detected in fluids from serpentinite muds from Conical Seamount in the Mariana forearc, indicating that low-temperature seawater-peridotite ...

Petrogenesis of lavas from Detroit Seamount: Geochemical differences between Emperor Chain and Hawaiian volcanoes [PDF]

open access: yes, 2005
The Hawaiian Ridge and Emperor Seamount Chain define a hot spot track that provides an 80 Myr record of Hawaiian magmatism. Detroit Seamount (∼76 to 81 Ma) is one of the oldest Emperor Seamounts.

Insights into the structure of grey reef shark aggregation, Carcharhinus amblyrhynchos (Bleeker, 1856), in two distinct channels of the Maldivian archipelago, Indian Ocean

open access: yesJournal of Fish Biology, EarlyView.
Abstract The grey reef shark Carcharhinus amblyrhynchos is one of the most frequently encountered reef‐associated shark species in the Maldives, yet very little is known about its local size structure or population dynamics. This study provides new insights into two aggregations of C.

Deformation and faulting of subduction overriding plate caused by a subducted seamount

open access: yesGeophysical Research Letters, 2016
We conducted numerical experiments to simulate elastoplastic deformation of the overriding plate caused by a subducted seamount. Calculations revealed development of a distinct pair of fault‐like shear zones, including a landward dipping forethrust fault

Sablefish, Anoplopoma fimbria, Populations on Gulf of Alaska Seamounts [PDF]

open access: yes, 2004
Sablefish, Anoplopoma fimbria, were tagged and released on Gulf of Alaska seamounts during 1999–2002 to determine the extent, if any, of emigration from the seamounts back to the continental slope and of movement between seamounts.

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

open access: yesJournal 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 ...

Hydrothermal Activity at a Cretaceous Seamount, Canary Archipelago, Caused by Rejuvenated Volcanism

open access: yesFrontiers in Marine Science, 2020
Our knowledge of venting at intraplate seamounts is limited. Almost nothing is known about past hydrothermal activity at seamounts, because indicators are soon blanketed by sediment.

Improved Bathymetric Prediction Using Geological Information: SYNBATH

open access: yesEarth and Space Science, 2022
To date, ∼20% of the ocean floor has been surveyed by ships at a spatial resolution of 400 m or better. The remaining 80% has depth predicted from satellite altimeter‐derived gravity measurements at a relatively low resolution.

The state of knowledge on four families of Syngnathoidei fishes (Teleostei: Syngnathiformes): Aulostomidae, Centriscidae, Fistulariidae and Solenostomidae

open access: yesJournal of Fish Biology, EarlyView.
Abstract Knowledge on the ecology and life‐history traits of coastal marine species is vital to inform their conservation and management, especially as their coastal habitats come under increasing threats. However, such data have never been collated for four of the five families in the suborder Syngnathoidei—the close relatives of the better‐studied ...
