Mesopelagic microbial carbon production correlates with diversity across different marine particle fractions

The ISME Journal, 2021
The vertical flux of marine snow particles significantly reduces atmospheric carbon dioxide concentration. In the mesopelagic zone, a large proportion of the organic carbon carried by sinking particles dissipates thereby escaping long term sequestration.

Synthetic and Semi-Synthetic Microplastic Ingestion by Mesopelagic Fishes From Tristan da Cunha and St Helena, South Atlantic

Frontiers in Marine Science, 2021
Mesopelagic fishes were sampled around Tristan da Cunha and St Helena in the South Atlantic from the RRS Discovery at depths down to 1000 m. Sampling was part of the Blue Belt Programme, a marine survey of British Overseas Territories funded by the ...

Solitary phytoplankton cells sink in the mesopelagic ocean. [PDF]

PLoS One
AbstractPhytoplankton, and their carbon, are typically exported from the surface ocean when packaged inside larger, sinking detrital particles. This process draws carbon out of the atmosphere, where it can be sequestered for long time periods in the deep ocean.

Protecting ocean carbon through biodiversity and climate governance

Frontiers in Marine Science, 2022
Global policy goals for halting biodiversity loss and climate change depend on each other to be successful. Marine biodiversity and climate change are intertwined through foodwebs that cycle and transport carbon and contribute to carbon sequestration ...

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

Efficient biological carbon export to the mesopelagic ocean induced by submesoscale fronts

Nature Communications
Submesoscale processes are ubiquitous in the North Pacific Subtropical Gyre. The authors show that carbon export efficiency is significantly strengthened under the influence of these episodic features by using high-frequency BGC-Argo observations ...

The Open-Ocean Gulf of Mexico After Deepwater Horizon: Synthesis of a Decade of Research

Frontiers in Marine Science, 2022
The scale of the Deepwater Horizon disaster was and is unprecedented: geographic extent, pollutant amount, countermeasure scope, and of most relevance to this Research Topic issue, range of ecotypes affected.

Modeling characterization of the vertical and temporal variability of environmental DNA in the mesopelagic ocean

Scientific Reports, 2021
Increasingly, researchers are using innovative methods to census marine life, including identification of environmental DNA (eDNA) left behind by organisms in the water column.

Integrating functional diversity, food web processes, and biogeochemical carbon fluxes into a conceptual approach for modeling the upper ocean in a high-CO2 world [PDF]

, 2005
Marine food webs influence climate by channeling carbon below the permanent pycnocline, where it can be sequestered. Because most of the organic matter exported from the euphotic zone is remineralized within the "upper ocean" (i.e., the water column ...
