Nitrogen Fixation About half of the planet's nitrogen fixation occurs out at sea by prokaryote diazotrophs, yet we still have a poor understanding of which ones do what. Karlusich et al. applied a combination of image capture and nitrogenase gene ( nifH ) sequencing on globally gathered data to map diazotrophs sampled at different depths. Unexpected hotspots of diazotroph abundance were discovered in the Mozambique Channel and the south Pacific Ocean. However, in the Arctic Ocean, nitrogen…
