Megafaunal Ecology of the Western Clarion Clipperton Zone

Frontiers in Marine Science, 2021
The Clarion Clipperton Zone (CCZ) is a vast area of the central Pacific Ocean where the abyssal seabed is a focus for future polymetallic nodule mining.

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.

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.

The influence of mid-ocean ridges on euphausiid and pelagic ecology [PDF]

, 2009
Chapters 1 & 2. Euphausiids comprise a major component of ecosystems in the pelagic realm, the world’s largest habitat, but basin scale drivers of euphausiids diversity and abundance are poorly understood. Mid-Ocean Ridges are the largest topographical

Defining the Word “Seamount” [PDF]

Oceanography, 2010
Reading through this issue of Oceanography, it will become apparent that researchers in different disciplines see their seamounts in quite different ways.

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 ...

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

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 ...
