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 ...

Paleomagnetism of Suiko Seamount, Emperor Seamount Chain

Geophysical Research Letters, 1978
Using data from a topographic and magnetic survey, the magnetization vector of Suiko seamount near the middle of the Emperor seamount chain (44.5°N, 170°E) was calculated. An inclination of −31° ± 9° and a declination of 213° ± 9° was found, although the goodness ratio is poor (R = 1.1).

Deep blueprint: A literature review and guide to automated image classification for ecologists

Journal of Animal Ecology, EarlyView.
A practical, literature‐grounded review that gives ecologists a clear, modular workflow for deep learning image classification. With code, GUIs and a novel deep sea case study (automated deep sea biotope classification) it lowers technical barriers and provides a usable blueprint for accelerating, standardising, and scaling ecological image analysis ...

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.

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 ...

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

Ocean Circulation Over North Atlantic Underwater Features in the Path of the Mediterranean Outflow Water: The Ormonde and Formigas Seamounts, and the Gazul Mud Volcano

Frontiers in Marine Science, 2019
Seamounts constitute an obstacle to the ocean circulation, modifying it. As a result, a variety of hydrodynamical processes and phenomena may take place over seamounts, among others, flow intensification, current deflection, upwelling, Taylor caps, and ...

Integrative Taxonomy Reveals Two New Species of Stalked Barnacle (Cirripedia, Thoracica) From Seamounts of the Western Pacific With a Review of Barnacles Distributed in Seamounts Worldwide

Frontiers in Marine Science, 2020
Dozens of samples of stalked barnacles were collected from deep-sea seamounts of the tropical western Pacific by remotely operated vehicles during two expeditions in 2017 and 2018.

Observer coverage and interaction rates determine the choice between design‐based and machine learning bycatch estimators for rare species

Conservation Biology, EarlyView.
Abstract Robust estimates of the magnitude of protected species bycatch are essential for effective fisheries management and marine conservation. Existing bycatch estimation methods typically struggle to accurately and precisely estimate the bycatch of rare species as a result of the statistical assumptions necessary to overcome infrequent encounters ...
