I did see that, but the article seemed to want it both ways: the nutrients are there to feed the krill, but they are all the way down to the abyss where they'll never decompose before they become sediment carbon (sequestered). It cannot be both I think, and I don't know which is prevalent, so did not try to calculate. But I was in the Navy briefly, and the phrase "lower than whale shit" has never been forgotten . . .

Any process that sinks carbon to below 2000 feet has basically removed it from the atmosphere for at least several centuries. There is a whole area of documentation of carbon disposal arising called MRV (Measurement, Reporting and Verification) - when they start certifying whale shit, we will know that bureaucracy has fully permeated the planet.
