First records of two rare and enigmatic nematodes, Rhaptothyreus typicus Hope & Murphy, 1969 and Bodonema vossi Jensen, 1991 (Nematoda, Rhaptothyreidae and Bodonematidae), from seamounts in the Andaman Sea [PDF]

Check List
We collected sediment samples from seamounts in the Andaman Sea, India, onboard RV Sindhu Sankalp using a spade corer. Rhaptothyreus typicus Hope & Murphy, 1969 was collected from a hydrothermally active seamount, whereas Bodonema vossi Jensen ...

Multidisciplinary indicators for confirming the existence and ecological effects of a Taylor column in the Tropical Western Pacific Ocean

Ecological Indicators, 2021
The Taylor column, a typical hydrological structure around a seamount, can help to explain the high biomass and biodiversity around the seamount. However, it is difficult to observe a Taylor column in the field because it is easy to be destroyed by the ...

Changes in nematode communities in different physiographic sites of the condor seamount (north-East atlantic ocean) and adjacent sediments.

PLoS ONE, 2014
Several seamounts are known as 'oases' of high abundances and biomass and hotspots of biodiversity in contrast to the surrounding deep-sea environments. Recent studies have indicated that each single seamount can exhibit a high intricate habitat turnover.

Fine-Scale Mapping of Mega-Epibenthic Communities and Their Patch Characteristics on Two New Zealand Seamounts

Frontiers in Marine Science, 2021
Seamounts are common features of the deep seafloor that are often associated with aggregations of mega-epibenthic fauna, including deep-sea corals and sponges.

Magnetization of the La Palma Seamount Series: Implications for seamount paleopoles [PDF]

Journal of Geophysical Research: Solid Earth, 1993
Paleopoles determined from seamount magnetic anomalies constitute the major data source for the Pacific apparent polar wander path, but relatively little is known about the processes of remanence acquisition in seamounts. Since magnetic anomalies reflect both natural remanence (NRM) and the induced field, it is important first to assess whether the NRM

Relative Timing of Off‐Axis Volcanism From Sediment Thickness Estimates on the 8°20’N Seamount Chain, East Pacific Rise

Geochemistry, Geophysics, Geosystems, 2022
Volcanic seamount chains on the flanks of mid‐ocean ridges record variability in magmatic processes associated with mantle melting over several millions of years.

Geographic Range Expansion and Taxonomic Notes of the Shortfin Neoscopelid Neoscopelus cf. microchir (Myctophiformes: Neoscopelidae) in the North-Eastern Atlantic

Journal of Marine Science and Engineering, 2022
One specimen of the shortfin neoscopelid Neoscopelus microchir Matsubara, 1943, has been recorded for the first time on the Porcupine Bank, southwestern Ireland, providing a new northern limit of distribution for the eastern Atlantic.

Evidence for spatial variability in the geoacoustic parameters of the Atlantis II seamount flanks [PDF]

JASA Express Letters
During a May 2023 cruise of the New England Seamount Acoustics Experiment, a near-surface airgun was fired at 1-min intervals along a nominally semi-circular track centered on the Atlantis II seamount.

Spotlight 2: Jasper Seamount [PDF]

Oceanography, 2010
Jasper Seamount is a submarine volcano in the Fieberling-Guadalupe seamount trail, located off the coast of Baja California, Mexico. It rises from the 4000-m-deep seafloor to a summit depth of 700 m.
