Physical controls on heterogeneous mesopelagic biogeochemistry [PDF]

Communications Earth & Environment
The surface and interior ocean are connected through physical processes that act in three dimensions and on subseasonal timescales. Numerical models and observations both highlight the importance of these eddying dynamics on shaping the biogeochemical and biological variability in the upper mesopelagic ocean.

Finding mesopelagic prey in a changing Southern Ocean [PDF]

Scientific Reports, 2019
AbstractMesopelagic fish and squid occupy ocean depths extending below the photic zone and their vertical migrations represent a massive pathway moving energy and carbon through the water column. Their spatio-temporal distribution is however, difficult to map across remote regions particularly the vast Southern Ocean.

Projected 21st century compression of mesopelagic habitat in the California current [PDF]

Scientific Reports
Although the mesopelagic zone occupies a substantial volume of the world’s oceans, our results suggest that the livable portion may compress vertically by ~ 40 m or ~ 39% by the end of the century.

Microplastic interactions with North Atlantic mesopelagic fish [PDF]

ICES Journal of Marine Science, 2015
AbstractMicroplastics in the marine environment are well documented, and interactions with marine biota have been described worldwide. However, interactions with vertically migrating fish are poorly understood. The diel vertical migration of mesopelagic fish represents one, if not the largest, vertical migration of biomass on the planet, and is thus an

Herding mesopelagic fish by light [PDF]

Marine Ecology Progress Series, 2019
To assess organisms forming mesopelagic scattering layers in the Red Sea, we took advantage of their reactions to light. We used a remotely operated vehicle (ROV) equipped with LED lamps for herding the acoustic targets down to the bottom (700 m), while concurrently monitoring the event by shipborne and deployed echosounders as well as video footage ...

Mesopelagic Fish Traits: Functions and Trade‐Offs [PDF]

Fish and Fisheries
ABSTRACTFishes inhabiting the mesopelagic zone of the world's oceans are estimated to account for the majority of the world's fish biomass. They have recently attracted new attention because they are part of the biological carbon pump and have been reconsidered as a contribution to food security.

Ocean Depths: The Mesopelagic and Implications for Global Warming [PDF]

Current Biology, 2017
The mesopelagic or 'twilight zone' of the oceans occurs too deep for photosynthesis, but is a major part of the world's carbon cycle. Depth boundaries for the mesopelagic have now been shown on a global scale using the distribution of pelagic animals detected by compiling echo-soundings from ships around the world, and been used to predict the effect ...

Mesopelagic fish off Mozambique [PDF]

, 1981
The mesopelagic fauna off Mozambique was studied on five cruises of R.V. "Dr. Fridtjof Nansen" during 1977 and 1978. It primarily consisted of Myctophids. At most stations, Benthosema fibulatum or Diaphus spp. were dominant. The abundance was estimated using a 38 kHz echo sounder and electronic integrators.

Solitary phytoplankton cells sink in the mesopelagic ocean [PDF]

PLOS One
Abstract Phytoplankton, 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.

Unlocking the Depths: Use of a Trait‐Based Approach to Reveal the Diversity of Foraging Strategies in a Deep‐Pelagic Fish Community [PDF]

Ecology and Evolution
Community trait structure is shaped by environmental filtering and limiting similarity, balancing abiotic selection and competitive divergence. In the context of environmental change and anthropogenic pressures, increasing our understanding of the ...
