The estimation of metabolism in the mesopelagic zone: Disentangling deep-sea zooplankton respiration [PDF]
Progress in Oceanography, 2019 Respiration in the mesopelagic layer is rather difficult to estimate but is of paramount importance to assess active flux, the downward carbon transport carried out by diel vertical migrants in the ocean.

Carbon cycling and POC turnover in the mesopelagic zone of the ocean: Insights from a simple model [PDF]
Deep-Sea Research Part II: Topical Studies in Oceanography, 2010 Carbon budgets of the mesopelagic zone are poorly constrained, highlighting our lack of understanding of the biota that inhabit this environment and their role in the cycling and sequestering of carbon in the deep ocean.

Archaeal dominance in the mesopelagic zone of the Pacific Ocean
Nature, 2001The ocean's interior is Earth's largest biome. Recently, cultivation-independent ribosomal RNA gene surveys have indicated a potential importance for archaea in the subsurface ocean. But quantitative data on the abundance of specific microbial groups in the deep sea are lacking. Here we report a year-long study of the abundance of two specific archaeal

Exploring the ecology of the mesopelagic biological pump [PDF]
Progress in Oceanography, 2019 The oceans’ biological pump (BP) exports large amounts of particulate organic carbon (POC) to the mesopelagic zone (base of the euphotic zone – 1000 m depth).

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.

Distribution and diel vertical movements of mesopelagic scattering layers in the Red Sea [PDF]
Marine Biology, 2012 The mesopelagic zone of the Red Sea represents an extreme environment due to low food concentrations, high temperatures and low oxygen waters. Nevertheless, a 38 kHz echosounder identified at least four distinct scattering layers during the daytime, of ...

Profiles of ectoenzymes in the Indian Ocean: phenomena of phosphatase activity in the mesopelagic zone [PDF]
Aquatic Microbial Ecology, 1999 Phosphatase (P-ase) activity was determined together with other extracellular enzyme activities, bacterial abundance and production rates during the 2 SW Monsoon process studies of the German JGOFS Arabian Sea Program. Water samples were collected along the cruise tracks from the equator to the upwelling region at the shelf edge off Oman.

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
