Exploring the ecology of the mesopelagic biological pump

open access: yesProgress 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).

Adaptations in mesopelagic fishes

Marine Biology, 1989
Mesopelagic fishes were collected from depths of 400 to 900 m off Oregon (USA) in September 1983, October 1985 and June 1989. Species of mesopelagic fish without diel vertical migrations (non-migrators) are known to have high body-and muscle-water contents relative to epipelagic and vertically migrating mesopelagic species.

Musculotendinous system of mesopelagic fishes: Stomiiformes (Teleostei)

Journal of Anatomy, 2021
AbstractEvery night the greatest migration on Earth starts in the deep pelagic oceans where organisms move up to the meso‐ and epipelagic to find food and return to the deeper zones during the day. One of the dominant fish taxa undertaking vertical migrations are the dragonfishes (Stomiiformes).

Mesopelagic microplankton of the Arabian Sea

Deep Sea Research Part I: Oceanographic Research Papers, 2003
Abstract The Arabian Sea is notable for its dramatic monsoonal effects on euphotic zone biogeochemical processes and the large spatial extent of its mesopelagic oxygen minimum zone. As part of the US Joint Global Ocean Flux Study Arabian Sea project, we sampled microplankton (organisms 20–200 μm including diatoms, dinoflagellates, ciliates ...

Metabolic biochemistry and the making of a mesopelagic mammal

Experientia, 1992
Large seals such as northern and southern elephant seals and Weddell seals are able to dive for startling duration and enormous depth. The current dive duration record is 120 minutes (recorded for the southern elephant seal); the current depth record is 1.5 km (recorded for the northern elephant seal).

Ink utilization by mesopelagic squid

Marine Biology, 2007
Remotely operated vehicle dive video recordings of deep-sea squid ink release were examined to determine species, ink release type, release depth, and accompanying behavior/s. Ink release was commonly observed between the surface and 1,842.1 m in Monterey Bay, CA, and surrounding waters.

SWIMMING WITH MESOPELAGICS

2007
A collaborative effort called MEDUZA was established in 2002 between US, Croatian and Slovenian scientists to investigate gelatinous zooplankton ecology in the southern Adriatic Sea. In conjunction with the MEDUZA program, several cruises were made to a 1200 m depth station characterized by clear, oligotrophic surface waters largely devoid of metazoan ...

Sensory Brain Areas in Mesopelagic Fishes

Brain, Behavior and Evolution, 2001
Four areas of the brain that receive primary projections from chemical senses ([1] olfactory bulb, [2] facial and vagal lobes), the eye ([3] optic tectum), and somato- and mechanosensory systems such as the lateral line, vestibular and auditory systems ([4] trigeminal and octavolateral regions) have been studied and relative size differences used to ...

Archaeal dominance in the mesopelagic zone of the Pacific Ocean

Nature, 2001
The 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
