The hadal zone represents one of the last great frontiers in marine science, accounting for 45% of the total ocean depth range. Despite very little research effort since the 1950s, the last ten years has seen a renaissance in hadal exploration, almost certainly as a result of technological advances that have made this otherwise largely inaccessible ...

Death of a Hadal Deep-Sea Bacterium After Decompression
Science, 1983An obligately barophilic bacterium that was recovered from a depth of 10,476 meters in the Pacific Ocean slowly lost colony-forming ability (assayed at 101.3 megapascals and 2°C) during incubation at atmospheric pressure and 0°C.

Menzies (1965) made the first attempt at reviewing the environmental conditions in the deep sea. Whilst considered a milestone review of its day, it was largely based on limited point-source observations. The review was later updated and revised in light of subsequent global studies of a more holistic nature (e.g. Tyler, 1995; Thistle, 2003). The Tyler

Living Deep: A Synopsis of Hadal Trench Ecology
Marine Technology Society Journal, 2009AbstractThe ocean’s deepest environments are fraught with extreme conditions, including the highest hydrostatic pressures found on earth. The hadal zone, which encompasses oceanic depths from 6,000 to almost 11,000 m, is located almost exclusively within deep-sea trenches.

The hadal biosphere: Recent insights and new directions
Deep Sea Research Part II: Topical Studies in Oceanography, 2018Abstract The hadal zone is the deep ocean with depths exceeding 6000 m. With an area approximately equal to the size of Australia, but constituting the deepest 45% of the vertical depth of the global ocean, it should come as no surprise that the hadal zone is the last great frontier of the ocean science.

Zoogeography of the Abyssal and Hadal Zones
1997Abstract Deep-sea bottom-living macroinvertebrates occurring below 3000 m depth include some species with a broad cosmopolitan geographical distribution and others with more limited, sometimes local, ranges. Taxa containing a large number of species with a wide vertical range (eurybathic) have a wider horizontal distribution than those dominated by ...

Anatomy of the Hadal Limpet Macleaniella moskalevi (Gastropoda, Cocculinoidea)
Invertebrate Biology, 1999The anatomy of the hadal, cocculinid limpet Macleaniella moskalevi is described. This species has a small, symmetrical, cap-shaped shell with a prominent internal transverse septum. As in other cocculinid genera, broad oral lappets and epipodial tentacles are present.

A Hadal Fish (Bassogigas profundissimus) with a Functional Swimbladder
Nature, 1964DURING the Danish Galathea Expedition (1950–52) a specimen of the brotulid fish, Bassogigas profundissimus (Roule, 1913), was caught in the Sunda trench (Station No. 466, depth 7,160 m); it measured 157 mm in standard length. The gear used was a herring otter trawl, which was operated at the bottom for a period of 2 h.

Development of 9000 m level hadal OBEM
Taking the sea area near the southern part of the Mariana Trench as a typical area is crucial for deep structural research in marine geology and geophysics. The magnetotelluric (MT) method has advantages such as large detection depth, sensitive to low resistance reactions, low cost, and high efficiency.Sixuan Song +4 more

Hidden dangers: High levels of organic pollutants in hadal trenches
Water ResearchThe "V"-shaped structure of hadal trenches acts as a natural collector of organic pollutants, drawing attention to the need for extensive research in these areas. Our review identifies significant concentrations of organic pollutants, including persistent organic pollutants, black carbon, antibiotic-resistant genes, and plastics, which often match ...
