Science governs the future of the mesopelagic zone [PDF]

npj Ocean Sustainability, 2022
AbstractScientists have studied the open ocean’s mesopelagic zone, extending from 200m-1000m depth, for more than 70 years. As renewed interest in this global ecosystem grows, divergent proposals and knowledge claims are being made on its current and future role in supporting human life.

Methane filtration and metabolic cooperation of microbial communities in cold seep water columns from South China Sea [PDF]

Communications Biology
Microbes in cold seep water columns are essential for methane sequestration and biogeochemical cycling, yet their structures and ecological functions, particularly at the bottom water interface (BWI), are poorly understood. Here, we performed metagenomic

Seasonal dynamics of SAR11 populations in the euphotic and mesopelagic zones of the northwestern Sargasso Sea [PDF]

The ISME Journal, 2008
Abstract Bacterioplankton belonging to the SAR11 clade of a-proteobacteria were counted by fluorescence in situ hybridization (FISH) over eight depths in the surface 300 m at the Bermuda Atlantic Time-series Study (BATS) site from 2003 to 2005.

Individual daytime swimming of mesopelagic fishes in the world's warmest twilight zone

Deep Sea Research Part I: Oceanographic Research Papers, 2022
We assessed the activity and swimming patterns of mesopelagic fishes in the Red Sea using bottom-moored, upward-facing echosounders deployed at 555 and 700 m depth. The vertically migrating mesopelagic scattering layer descended close to the bottom during daytime.

Three-Dimensional Imaging Lidar for Characterizing Particle Fields and Organisms in the Mesopelagic Zone [PDF]

Frontiers in Marine Science, 2020
The ocean’s mesopelagic zone is largely uncharacterized despite its vital role in sustaining ocean ecosystems. The composition, cycling, and fate of particle fields in the mesopelagic lacks an integrative multi-scale understanding of organism migration patterns, distribution, and diversity.

Slow-sinking particulate organic carbon and its attenuation in the mesopelagic water of the South China Sea

Frontiers in Marine Science, 2022
Coastal acidification has been widely investigated in terms of its rationale and ecological effects in the last decade. However, the driving mechanism for acidification in open seawater, especially in mesopelagic water, is still poorly understood.

Otolith characterization and integrative species identification of adult mesopelagic fishes from the western North Atlantic Ocean

Frontiers in Marine Science, 2023
Fish diversity and ecology in the ocean’s mesopelagic zone are understudied compared to other marine regions despite growing interest in harvesting these potential resources.

A global biogeographic classification of the mesopelagic zone

Deep Sea Research Part I: Oceanographic Research Papers, 2017
We have developed a global biogeographic classification of the mesopelagic zone to reflect the regional scales over which the ocean interior varies in terms of biodiversity and function. An integrated approach was necessary, as global gaps in information and variable sampling methods preclude strictly statistical approaches. A panel combining expertise

Diversity and ecological dynamics of bioluminescent bacteria in the mesopelagic zone

Mesopelagic ecosystems, located between 200 and 1000 meters deep are poorly studied. They are characterized by complete darkness, driving organisms to develop specialized adaptive strategies1. One of the most remarkable of these adaptations is bioluminescence, enabling organisms to produce light for communication, camouflage, prey attraction, or ...

Increased ocean carbon export in the Sargasso Sea linked to climate variability is countered by its enhanced mesopelagic attenuation [PDF]

Biogeosciences, 2010
Photosynthetic CO2 uptake by oceanic phytoplankton and subsequent export of particulate organic carbon (POC) to the ocean interior comprises a globally significant biological carbon pump, controlled in part by the composition of the planktonic community.
