High Latitude Epipelagic and Mesopelagic Scattering Layers—A Reference for Future Arctic Ecosystem Change

Frontiers in Marine Science, 2017
Scattering structures, including deep (>200 m) scattering layers are common in most oceans, but have not previously been properly documented in the Arctic Ocean.

A Preliminary Study of Suspended Matters Variation Associated with Hypoxia and Shoaling Internal Tides on the Continental Shelf of the Northern Andaman Sea

Journal of Marine Science and Engineering, 2023
The northern Andaman Sea (AS) continental shelf is unique due to the diverse marine ecosystem and existences of both hypoxia and internal tides, but limited in situ observations restrict our understanding of the hydrographic dynamic process. Based on the

Tracking Long‐Term Trends in Sockeye Salmon (Oncorhynchus nerka) Population Dynamics Using Sterol and Stanol Biomarkers in Lake Sediments

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 9, September 2025.
Abstract We analyzed biomarkers, including sterols, stanols, and δ15N, in sediment cores from lakes with well‐documented sockeye salmon return histories. Our goal was to improve estimates of past changes in salmon escapement, that is, the population that return to their freshwater nursery lakes, inferred using sediment biogeochemical markers ...

Body Size Regression Formulae, Proximate Composition and Energy Density of Eastern Bering Sea Mesopelagic Fish and Squid. [PDF]

PLoS ONE, 2015
The ecological significance of fish and squid of the mesopelagic zone (200 m-1000 m) is evident by their pervasiveness in the diets of a broad spectrum of upper pelagic predators including other fishes and squids, seabirds and marine mammals.

Highly mobile pelagic species co‐occur with fine‐scale ocean fronts

Limnology and Oceanography, Volume 70, Issue 7, Page 1901-1912, July 2025.
Abstract Coastal areas are an important source of food and a valuable tourism asset for communities, but also highly dynamic and heterogeneous environments. Understanding how marine species respond to the variability of their habitat is essential to sustainably manage coastal resources.

Microbial Remineralization Is a Depth‐Varying Contributor to Particle Flux Attenuation in the Southern Ocean

Global Biogeochemical Cycles, Volume 39, Issue 7, July 2025.
Abstract The biological carbon pump contributes to set the magnitude of carbon sequestration in the oceans' interior. Estimating the relative contribution of microbial versus zooplankton‐mediated processes to particulate organic carbon (POC) flux attenuation provides insights into how this pump functions.

Seasonal Changes of Size Spectra of the Benguela Offshore Mesopelagic Ecosystem Compartment in Relation to Primary Production

Marine Ecology, Volume 46, Issue 4, July/August 2025.
ABSTRACT Seasonal differences in marine size spectra of micronekton at the shelf‐ocean interface of the northern (NBUS) and southern Benguela upwelling system (SBUS) in Feb–Mar 2019 and Sep–Oct 2021 were analysed for mesopelagic fishes and total micronekton, the latter also including invertebrates.

Composition and Functional Diversity of Juvenile Groundfish Assemblages in the California Current

Journal of Biogeography, Volume 52, Issue 5, May 2025.
ABSTRACT Aim Long‐term monitoring data at the biogeographic scale are essential for developing baselines of biodiversity patterns and tools to diagnose natural cycles, trends, and anomalous events to assess threats from climate change. However, studies using these data often limit their analyses to relatively few metrics that may not adequately capture

Известия ТИНРО, 2014
Data of 8 surveys conducted by Pacific Fish. Res. Center (TINRO) in the Pacific waters at Kuril Islands in 2004-2012 are summarized to consider forage base and food relationships of nekton and plankton and to estimate consumption of forage resourced by ...

Three‐dimensional conservation planning of fish biodiversity metrics to achieve the deep‐sea 30×30 conservation target

Conservation Biology, Volume 39, Issue 2, April 2025.
Abstract Accelerating rate of human impact and environmental change severely affects marine biodiversity and increases the urgency to implement the Convention on Biological Diversity (CBD) 30×30 plan for conserving 30% of sea areas by 2030. However, area‐based conservation targets are complex to identify in a 3‐dimensional (3D) ocean where deep‐sea ...
