The Fate of Deep-Sea Coral Reefs on Seamounts in a Fishery-Seascape: What Are the Impacts, What Remains, and What Is Protected?

Frontiers in Marine Science, 2020
Environmental harm to deep-sea coral reefs on seamounts is widely attributed to bottom trawl fishing. Yet, accurate diagnoses of impacts truly caused by trawling are surprisingly rare.

Near-ridge-axis volcanism affected by hotspot: insights from effective elastic thickness and topography of the Ojin Rise Seamounts, east of Shatsky Rise in the northwest Pacific Ocean

Earth, Planets and Space, 2020
We used recently collected bathymetric data and published gravity data to examine the effective elastic thickness of the lithosphere and the crustal thickness beneath the Ojin Rise Seamounts, located east of Shatsky Rise in the northwest Pacific Ocean ...

A first assessment of the distribution and abundance of large pelagic species at Cocos Ridge seamounts (Eastern Tropical Pacific) using drifting pelagic baited remote cameras.

PLoS ONE, 2021
Understanding the link between seamounts and large pelagic species (LPS) may provide important insights for the conservation of these species in open water ecosystems.

Volcanic complexes and tecton-magmatic stages of the evolution of the Magellan Seamounts (Pacific Ocean). Message 1: Volcanic complexes

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2022
The paper presents original and published data of radioisotope dating of volcanic rocks of the Magellan Seamounts. These data and available geological materials allow us to distinguish five major volcanic complexes of different ages in the guyots of the ...

Topology‐based Visual Analysis of Hydrothermal Plumes

Computer Graphics Forum, EarlyView.
Abstract Hydrothermal plumes are turbulent structures of intense heat and mineral smoke that rise and disperse into the deep ocean. Existing models generally characterize these systems as a single axisymmetric plume originating from a point source. However, this assumption breaks down in weakly venting, spatially distributed systems, where low‐flux ...

Seamount Discovery Tool Aids Navigation to Uncharted Seafloor Features [PDF]

Oceanography, 2010
Wessel et al. (2010) highlight the need for a systematic mapping of seamounts in ocean basins. They estimate that 100,000 or 90% of the seamounts greater than 1-km tall are unobserved by either ship soundings or satellite gravity.

Comparative species distribution model framework for marine conservation and its application to loggerhead turtles in the Mediterranean

Conservation Biology, EarlyView.
Abstract Modeling species distributions in dynamic pelagic environments remains challenging, particularly for wide‐ranging and highly mobile species when there is limited guidance on model performance. This limitation constrains the effective use of species distribution models (SDMs) in marine conservation, where robust and transferable predictions are
