Harpacticoida (Crustacea, Copepoda) across a longitudinal transect of the Vema Fracture Zone and along a depth gradient in the Puerto Rico trench [PDF]
, 2018 The aim of this study was the investigation of abundance, composition and biodiversity of benthic deep-sea Harpacticoida (Crustacea, Copepoda) in the Verna Fracture Zone (VFZ) and Puerto Rico trench. The study revealed a clear East-West gradient in total

Environmental Microbiology, 2023 Abstract Microbial communities in marine sediments are highly diverse, yet the processes that give rise to this complexity are unclear. It has been proposed that benthic microbial communities must be continuously re‐seeded from the water column because dispersal within the sediment is severely limited.

Deep Sea Research Part II: Topical Studies in Oceanography, 2017 Abstract Despite the increasing sampling effort that occurred in the deep-sea environment during the last decades, knowledge about meiofauna ecology in trenches and Fracture Zones is still scarce. Based on the lack of this information, a longitudinal transect across the Vema Fracture Zone in the North Atlantic was sampled to test whether meiofauna ...

High-density element concentrations in fish from subtidal to hadal zones of the Pacific Ocean [PDF]
Heliyon, 2018 Anthropogenic use of high density, toxic elements results in marine pollution which is bio-accumulating throughout marine food webs. While there have been several studies in various locations analyzing such elements in fish, few have investigated patterns in these elements and their isotopes in terms of ocean depth, and none have studied the greatest ...

Perspectives on the Terrestrial Organic Matter Transport and Burial along the Land-Deep Sea Continuum: Caveats in Our Understanding of Biogeochemical Processes and Future Needs [PDF]
, 2016 The natural carbon cycle is immensely intricate to fully understand its sources, fluxes and the processes that are responsible for their cycling in different reservoirs and their balances on a global scale.

Composition of abyssal macrofauna along the Vema Fracture Zone and the hadal Puerto Rico Trench, northern tropical Atlantic [PDF]
Deep Sea Research Part II: Topical Studies in Oceanography, 2017 Abstract We analyzed composition and variations in benthic macrofaunal communities along a transect of the entire length of the Vema-Fracture Zone on board of RV Sonne (SO-237) between December 2014 and January 2015 in order to test whether the Mid-Atlantic Ridge serves as a barrier limiting benthic taxon distribution in the abyssal basins on both ...

Fishes of the hadal zone including new species, in situ observations and depth records of Liparidae
, 2016 Observations and records for fish exceeding 6000 m deep are few and often spurious. Recent developments in accessing and sampling the hadal zone 6000–11,000 m) have led to an acceleration in new findings in the deep subduction trenches, particularly in ...

Have we so far only seen the tip of the iceberg? Exploring species diversity and distribution of the giant amphipod Eurythenes [PDF]
, 2016 Additional material of the iconic giant amphipod Eurythenes was investigated. Recently, the species E. gryllus has been separated into 12 distinct species-level lineages of which several have been described as distinct species, based on both morphology ...

Metabolic rates are significantly lower in abyssal Holothuroidea than in shallow-water Holothuroidea [PDF]
, 2018 Recent analyses of metabolic rates in fishes, echinoderms, crustaceans and cephalopods have concluded that bathymetric declines in temperature- and mass-normalized metabolic rate do not result from resource-limitation (e.g. oxygen or food/chemical energy)

The deepest chemosynthesis-based community yet discovered from the hadal zone, 7326 m deep, in the Japan Trench [PDF]
Marine Ecology Progress Series, 1999 A dense community of benthic animals was discovered by the Japanese ROV 'Kaiko' in the hadal zone near the bottom of the Japan Trench, 7326 m deep. The community was dominated by a new species of thyasirid bivalve Maorithyas hadalis. This community appears to be sustained by chemosynthesis (nutrients being derived from reduced compounds within the ...
