VERDA: A Multisampler Tool for Mesopelagic Nets

Journal of Marine Science and Engineering, 2023
Different types and systems to discriminate plankton samples at different strata in the water column have been developed in recent decades. For sampling at sufficient depth, opening and closing zooplankton multinets are ideal because there is no ...

Swimbladder properties of Cyclothone spp. in the northeast Atlantic Ocean and the Western Mediterranean Sea

Frontiers in Marine Science, 2023
Non-migratory bristlemouth fishes (Cyclothone spp.) are the most abundant vertebrates on Earth and play an important role in the biological carbon pump by remineralizing organic carbon in deep ecosystems.

Characterizing the Sound-Scattering Layer and Its Environmental Drivers in the North Equatorial Current of the Central and Western Pacific Ocean

Journal of Marine Science and Engineering, 2023
Acoustic technology is an essential tool for detecting marine biological resources and has been widely used in sound-scattering layer (SSL) research. The North Equatorial Current (NEC) warm pool region of the Central and Western Pacific Ocean has a vast ...

Acoustic characterisation of micronekton distribution in French Polynesia [PDF]

Marine Ecology Progress Series, 1999
Tuna distribution may be directly linked to food availability, the density of which can be assessed by echo-sounding. A study was performed in the French Polynesian EEZ (Economic Exclusive Zone) between 1995 and 1997 with a 38 kHz echo sounder working down to 500 m depth.

Ecological Trap or Favorable Habitat? First Evidence That Immature Sea Turtles May Survive at Their Range-Limits in the North-East Atlantic

Frontiers in Marine Science, 2021
Unusual environmental events can push marine animals outside their physiological tolerances through changes in trophic and/or thermal conditions. Such events typically increase the risk of stranding.

Variability in micronekton active carbon transport estimates on the Southwest Coast of Oahu using three different sampling gears

Frontiers in Marine Science, 2022
Micronekton were sampled off the southwest coast of Oahu in October of 2004 as part of the North Pacific Marine Sciences Organization (PICES) Micronekton Sampling Gear Intercalibration experiment (MIE-1).

Exploring the future of the Coral Sea micronekton

Progress in Oceanography, 2021
Abstract Ecosystem models forced by future climate simulations outputs from the Coupled Model Intercomparison Project Phase 5 (CMIP5) simulate a substantial decline of tropical marine animal biomass over the course of the 21st century. Regional projections are however far more uncertain because of well-known biases common to most CMIP5 historical ...

Modeling the contribution of micronekton diel vertical migrations to carbon export in the mesopelagic zone [PDF]

Biogeosciences
Micronekton plays a significant but often overlooked role in carbon transport within the ocean. Using a one-dimensional trait-based model, we simulated the diel vertical migrations (DVMs) of micronekton and their carbon production through respiration ...

Zooplankton and Micronekton Active Flux Across the Tropical and Subtropical Atlantic Ocean

Frontiers in Marine Science, 2019
Quantification of the actual amount of carbon export to the mesopelagic layer by both zooplankton and micronekton is at present a gap in the knowledge of the biological pump.
