Seamount Fisheries: Do They Have a Future? [PDF]

Oceanography, 2010
Today, seamount fish populations are in trouble following a dismal 30-year history of overexploitation, depletion, and collapse, with untold consequences for global biodiversity and the complex, delicate, but poorly understood, open-ocean food webs ...

210Pb-Derived Bioturbation Rates in Sediments Around Seamounts in the Tropical Northwest Pacific

Frontiers in Marine Science, 2021
To evaluate bioturbation coefficients (DB) and mixing depths (L), 210Pb and 226Ra activity was measured in two sediments cores (from water depths of 5,398 m and 4,428 m), which were collected from seamount areas in the Northwest Pacific.

First Insight of Meso- and Bentho-Pelagic Fish Dynamics Around Remote Seamounts in the South Atlantic Ocean

Frontiers in Marine Science, 2021
Seamounts have long been recognised as hotspots for pelagic productivity and diversity in the world’s open ocean habitats. Recent studies have suggested that productivity may vary greatly between different seamounts, depending on complex interactions ...

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).

Composition and assembly of the microbial community within the deep chlorophyll maximum layer of the seamount and the adjacent coastal waters in the South China Sea

mSphere
Seamounts are generally recognized as hotspots of microbial biodiversity in the ocean, and their topography and hydrography around the seamounts significantly influence microbial biogeography.

Seamount Ecosystem Evaluation Framework (SEEF): A Tool for Global Seamount Research and Data Synthesis [PDF]

Oceanography, 2010
The Seamount Ecosystem Evaluation Framework (SEEF) is an innovative multidisciplinary tool developed to standardize the parameters by which seamounts are characterized, to report the extent of knowledge about individual seamounts, and to identify and ...

Vertically Exported Phytoplankton (< 20 µm) and Their Correlation Network With Bacterioplankton Along a Deep-Sea Seamount

Frontiers in Marine Science, 2022
Phytoplankton have been observed to be widely distributed in the oceanic vertical water columns and have an important contribution to carbon sequestration via biological pump mechanism. However, in seamount areas with strong hydrodynamics, their vertical

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 ...

Surveys of seamounts in the Southern Indian Ocean during the 37th and 38th Japanese Antarctic Research Expedition in 1995 and 1996

Antarctic Record, 1998
Surveys of seamounts in the Southern Indian Ocean were carried out during the 37th and 38th Japanese Antarctic Research Expedition (JARE-37 and JARE-38). Previous uncharted seamounts were identified on board the icebreaker SHIRASE.

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 ...
