The oceanic waters below a depth of 200 m represent, in terms of volume, the largest habitat of the biosphere, harboring approximately 70% of the prokaryotic biomass in the oceanic water column. These waters are characterized by low temperature, increasing hydrostatic pressure, and decreasing organic matter supply with depth. Recent methodol...

Generating environmental baseline knowledge is a prerequisite for evaluating and predicting the effects of future deep seabed mining on the seafloor and in the water column. Without baselines, we lack the information against which to assess impacts and therefore cannot decide whether or not they pose an acceptable risk to the marine environment. At...

The darkness of the deep ocean limits the vision of diving predators, except when prey emit bioluminescence. It is hypothesized that deep-diving seals rely on highly developed whiskers to locate their prey. However, if and how seals use their whiskers while foraging in natural conditions remains unknown. We used animal-borne tags to show that free-...

The amplitude–phase structure and interferograms of the sound pressure and effective phase and group velocities in acoustically bright zones and deep ocean shadow zone are investigated. Analysis of the angular structure of interferograms on the frequency–range plane made it possible to establish that the effective phase and group velocities are fun...
The ocean is mostly deep, with most of its volume (>80%) at depths greater than 1000 m, and is poorly sampled (

The paper investigates the sound-pressure and phase-gradient distribution in the deep sea along signal propagation paths in the near and far acoustic brightness fields, as well as in the shadow zone. It is shown that the field characteristics formed by leaky, trapped, and water modes differ significantly. It was found that in zones of interference ...

IPCC reporting culture and structure leads to a failure to highlight potential vulnerabilities and risk in areas where research is largely absent. Nowhere is this more obvious than in treatment of the deep ocean (waters below 200 m), where climate research is in its infancy, but human exploitation of resources is on the rise. Understanding climate-...
