Even though the deeper layers of the ocean are warming at a slower pace than the surface, animals living in the deep ocean are more exposed to climate warming and will face increasing challenges to maintain their preferred thermal habitats in the future.

Large quantities of the greenhouse gas methane are stored in the seabed. Fortunately, only a small fraction of the methane reaches the atmosphere, where it acts as a climate-relevant gas, as it is largely degraded within the sediment. This degradation is carried out by a specialized community of microbes, which removes up to 90 percent of the escaping methane. Thus, these microbes are referred to as the “microbial methane filter.” If the greenhouse gas were to rise through the water and into the atmosphere, it could have a significant impact on our climate.

Long before humans started injecting carbon dioxide into the atmosphere by burning fossil fuels like oil, gas, and coal, the level of atmospheric CO2 rose significantly as the Earth came out of its last ice age. Many scientists have long suspected that the source of that carbon was from the deep sea.

The deep sea might be cold and dark, but it’s not barren. Down here, an incredible diversity of corals shelters young fish like grouper, snapper and rockfish. Sharks, rays and other species live and feed here their whole lives.

New rules are urgently needed to protect life in the open seas, scientists have warned.
A report to a UN ocean conference in New York points out that more than 60% of the ocean has no conservation rules as it’s outside national jurisdiction.

Imagine sinking into the deepest parts of the Central Pacific Ocean, somewhere between Mexico and Hawaii. Watch as the water turns from clear to blue to dark blue to black. And then continue on for 15,000 feet to the seafloor — roughly the distance from the peak of California’s Mount Whitney to the bottom of nearby Death Valley.
