Despite their prominence in the deep sea, ammonia oxidizing microbes don't play a huge role in carbon cycling. They're around, just not very active, starved for nitrogen... 🧪🌊

Minor contribution of ammonia oxidizers to inorganic carbon fixation in the ocean - Nature Geoscience
Ammonia oxidizers contribute minimally to carbon fixation in the dark ocean despite their abundance at depth, according to enzyme inhibition experiments on water samples from two cruises.
