A gas tension device for the mesopelagic zone
Deep Sea Research Part I: Oceanographic Research Papers, 2018Abstract Gas Tension Devices (GTDs) are used to acquire accurate and stable measurements of gas tension, or total dissolved air pressure of the gases dissolved in water. GTDs operate by measuring the barometric pressure of a small sample volume of air separated from the water by a gas-permeable membrane resting on a rigid permeable support.

Abundant nitrite-oxidizing metalloenzymes in the mesopelagic zone of the tropical Pacific Ocean
Nature Geoscience, 2020Numerous biogeochemical reactions occur within the oceans’ major oxygen minimum zones, but less attention has been paid to the open ocean extremities of these zones. Here we report measurements on oxygen minimum zone waters from the Eastern to the Central Tropical North Pacific, which we analysed using metaproteomic techniques to discern the microbial ...

Relationship between particle size distribution and flux in the mesopelagic zone
Deep Sea Research Part I: Oceanographic Research Papers, 2008Large aggregates commonly named “marine snow” are difficult to collect and study because of their fragile nature, but they make up the largest fraction of vertical carbon flux in the ocean. Developments in imaging sensors and computer systems have facilitated the development of in situ image acquisition systems that can be used to produce profiles of

Biomass, biodiversity, ecosystem services, and potential fisheries in the mesopelagic zone
2021No abstracts are to be cited without prior reference to the author.Conveners: Tom Langbehn (Norway), Helena McMonagle (USA), Peter H. Wiebe Due to the cancellation of ICES ASC 2020, some contributions submitted that year were also included in ASC 2021.

Vertical distribution and migration of fishes of the lower mesopelagic zone off Oregon
Marine Biology, 1982An exceptionally large midwater trawl (50 m2 mouth area) with 5 opening and closing codends was towed horizontally in the lower mesopelagic zone at depths of 500, 650, 800 and 1000 m off Oregon (USA) from 1–6 September, 1978. In comparison to more conventional trawls, ours collected more fish, including rare species and large individuals of common ...

Climate damage from fishing the mesopelagic zone exceeds its economic benefits
ICES Journal of Marine ScienceAbstract Mesopelagic fish represent an opportunity for fishing companies and food production, but their exploitation carries substantial environmental risks related to these populations’ role in the oceanic carbon pump. We assess the economic viability of mesopelagic fishing from a private economic perspective, focusing on costs and ...

Metabolism and chemical composition of crustaceans from the Antarctic mesopelagic zone
Deep Sea Research Part A. Oceanographic Research Papers, 1988Abstract Rates of oxygen consumption, ammonia excretion and phosphate excretion were measured in conjunction with analyses of water content, ash and four elements (carbon, hydrogen, nitrogen, phosphorus) on seven crustacean species from the mesopelagic zone (200–1000 m depth) in the Antarctic Ocean.

Carbon cycling in the Mesopelagic Zone of the central Arabian Sea: Results from a simple model
2009Using a 3-D hydrodynamic-ecosystem model, Anderson et al. (2007) investigated the carbon budget of the mesopelagic zone of the central Arabian Sea and concluded that the vertical supply of sinking particles from the euphotic zone is sufficient to meet the carbon demand of the mesopelagic biota. Justifying this conclusion, they argued that the predicted
