The Earth's 'twilight zone' could see its rich diversity of life reduced by the end of the century due to the climate crisis.
The ocean's mesopelagic zone, also called the"twilight zone," is located between 656 feet and 3,280 feet below the surface.
Over time, the calcium carbonate shells accumulate on the seafloor, preserving information about what the environment was like during their lifetime. The tiny shells effectively create a timeline of how the ocean has changed over millions of years."We still know relatively little about the ocean twilight zone, but using evidence from the past we can understand what may happen in the future," said lead study author Dr.
Warmer ocean temperatures also increase the metabolic rates of organisms, leading to increased food demand and oxygen consumption, according to the study. "There are no baseline data to compare what we are measuring against, so this study that looks at the composition of the fossil record over time is one of the few ways we can try to understand how we are causing the twilight zone to change," Rocha said.Based on what they discovered from the ancient warming events, the researchers combined that data with Earth system mode simulations — modeling of Earth's carbon cycle as it moves through the land, sea and atmosphere.
The low estimate was 625 billion metric tons, medium was 2,500 billion metric tons and high was 5,000 billion metric tons.
