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

Biogeosciences
Abstract. 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, fecal pellets, excretion, and dead bodies.

Temporal variability of dissolved iron species in the mesopelagic zone at Ocean Station PAPA

Journal of Marine Systems, 2017
Abstract Deposition of atmospheric aerosols to the surface ocean is considered an important mechanism for the supply of iron (Fe) to remote ocean regions, but direct observations of the oceanic response to aerosol deposition are sparse. In the high nutrient, low chlorophyll (HNLC) subarctic Pacific Ocean we observed a dissolved Fe and Fe(II) anomaly ...

Assessing the Time of Emergence of Marine Ecosystems From Global to Local Scales Using IPSL‐CM6A‐LR/APECOSM Climate‐To‐Fish Ensemble Simulations

Earth's Future
Climate change is anticipated to considerably reduce global marine fish biomass, driving marine ecosystems into unprecedented states with no historical analogs.

Mesopelagic microplankton of the Arabian Sea [PDF]

, 2003
The Arabian Sea is notable for its dramatic monsoonal effects on euphotic zone biogeochemical processes and the large spatial extent of its mesopelagic oxygen minimum zone.

New Documented Records of the Mesopelagic Fish Valenciennellus tripunctulatus (Sternoptychidae) in the Strait of Messina and a Review of Its Mediterranean Occurrences

Fishes
The constellation fish, Valenciennellus tripunctulatus, is a small mesopelagic teleost typically found in equatorial and temperate waters worldwide, although the species has been also rarely recorded in the Mediterranean Sea (less than 20 specimens from ...

Temperature-dependent oxygen utilization rates of the mesopelagic water in the Southeast Asian basins

Frontiers in Marine Science
IntroductionThe Southeast Asian Seas (SEAS), characterized by interconnected basins separated by shallow sills, serve as a critical pathway for the Indonesian throughflow (ITF), regulating Indo-Pacific climate and biogeochemical exchanges.
