- At deeper depths the bacteria develop unique adaptations to make do without sunlight and, in general, this leads to greater bacterial diversity at depth. About 70 percent of the ocean’s microbes live in the dark open ocean.

These microbes can be found covering the outer surface of the corals, deep within their tissue, or among the sediments beneath the reef where there are about 10,000 times the number of bacteria when compared to the surrounding water.
Mar 26, 2021 · 26 March 2021. How deep-sea bacteria thrive under pressure. Microbes that survive in the dark depths import and process a molecule in seawater to armour their innards. Subjected to pressures...

Below the photic zone (the uppermost, sunlit portion of the ocean), and especially at deep-ocean sites and around hydrothermal vents and seeps, microbes are chemosynthetic, meaning they derive energy from chemical reactions to drive their metabolic processes.
In fact, the global ocean comprises Earth’s biggest microbiome, with at least half of the ocean’s microbial biomass occurring beneath the ocean floor. Julie’s deep ocean microbes thriving on the surface in ovens on board R/V Falkor. It Starts with a Microbe.
Colwell and her then-graduate student, Jody Deming, demonstrate that entire communities of microorganisms can be barophilic using the microbes found in the guts of deep-sea animals. Some sea cucumbers found in the deep-sea are home to barophilic, or "pressure-loving," bacteria in their guts.
Mar 13, 2019 · Chemosynthetic bacteria and archaea form the foundation of vent ecosystems by exploiting the chemical disequilibrium between reducing hydrothermal fluids and oxidizing seawater, harnessing this...
