Antarctic Krill's are likely amongst the world’s most important carbon-storing organisms

Recommendable! This is only about the antarctic krill! What about the arctic krill?

We still know very little about the very complex natural phenomenon climate! Global Warming is a hoax and Climate Change is a religion! Climatology is more of a pseudoscience or nascent science then a mature  science.

"Antarctic krill are likely amongst the world’s most important carbon-storing organisms, according to a new study published in the influential Nature Communications journal. The findings, after a decade of research, have amazed the team behind the evaluation.

The researchers estimate that Antarctic krill (Euphausia superba) annually lock at least 20 million tonnes of carbon into the deep ocean.

These estimates put krill on a par with key coastal habitats such as saltmarshes, mangroves, and seagrasses, which sequester 13, 24 and 44 million tonnes of carbon per year, respectively. These areas are increasingly being placed in conservation zones due to their role in greenhouse gas reduction and habitat survival. ..."

From the abstract:

"The carbon sequestration potential of open-ocean pelagic ecosystems is vastly under-reported compared to coastal vegetation ‘blue carbon’ systems. Here we show that just a single pelagic harvested species, Antarctic krill, sequesters a similar amount of carbon through its sinking faecal pellets as marshes, mangroves and seagrass. Due to their massive population biomass, fast-sinking faecal pellets and the modest depths that pellets need to reach to achieve sequestration (mean is 381 m), Antarctic krill faecal pellets sequester 20 MtC per productive season (spring to early Autumn). This is equates USD$ 4 − 46 billion depending on the price of carbon, with krill pellet carbon stored for at least 100 years and with some reaching as far as the North Pacific. Antarctic krill are being impacted by rapid polar climate change and an expanding fishery, thus krill populations and their habitat warrant protection to preserve this valuable carbon sink."

Krill's role in carbon sequestration amazes scientists

Antarctic krill can lock away similar levels of carbon as seagrass and mangroves (original news release) "Small marine crustaceans are as valuable as key coastal habitats for storing carbon and should be similarly protected, according to new research."
