Oxygen minimum zone: An important oceanographic habitat for deep-diving northern elephant seals, Mirounga angustirostris. [PDF]

, 2017
Little is known about the foraging behavior of top predators in the deep mesopelagic ocean. Elephant seals dive to the deep biota-poor oxygen minimum zone (OMZ) (>800 m depth) despite high diving costs in terms of energy and time, but how they ...

Integrated Space-Time Dataset Reveals High Diversity and Distinct Community Structure of Ciliates in Mesopelagic Waters of the Northern South China Sea

Frontiers in Microbiology, 2019
Little is known about diversity distribution and community structure of ciliates in mesopelagic waters, especially how they are related to spatial and temporal changes.

Economic viability of a large vessel mesopelagic fishery under ecological uncertainty

Frontiers in Marine Science, 2023
Motivated by the global rise in demand for marine products, there is increased interest in exploitation of the mesopelagic zone. However, the feasibility of this potential fishery remains uncertain, partly due to limited biological data and knowledge on ...

Variation in mesopelagic fish community composition and structure between Mediterranean and Atlantic waters around the Iberian Peninsula

Frontiers in Marine Science, 2022
Mesopelagic fish populations are characterised by high species richness and abundance, and have been identified as important contributors to the active carbon fluxes in the open ocean. We report variability in communities of mesopelagic fish between five

Differences in the trophic ecology of micronekton driven by diel vertical migration. [PDF]

, 2019
Many species of micronekton perform diel vertical migrations (DVMs), which ultimately contributes to carbon export to the deep sea. However, not all micronekton species perform DVM, and the nonmigrators, which are often understudied, have different ...

Retinal properties of the mesopelagic fish Diaphus sp.: vision under dim light conditions

Frontiers in Marine Science, 2014
Deep-sea fishes inhabit an environment where light plays a crucial ecological role with consequences on their behaviour, but little is known on how visual adaptations evolved to these specific light conditions. The mesopelagic zone is the transition from

Bioactivity Profiling and Untargeted Metabolomics of Microbiota Associated with Mesopelagic Jellyfish Periphylla periphylla

Marine Drugs, 2023
The marine mesopelagic zone extends from water depths of 200 m to 1000 m and is home to a vast number and diversity of species. It is one of the least understood regions of the marine environment with untapped resources of pharmaceutical relevance.

An upper mesopelagic zone carbon budget for the subarctic North Pacific [PDF]

Biogeosciences
Abstract. Mesopelagic zone (MZ) carbon budgets comparing supply with demand can be difficult to constrain due to the temporal and spatial offsets between key sources and sinks, and due to nuances of the measurement techniques used, their associated uncertainties, and potential sampling biases.
