Description: |
The eastern tropical North Atlantic (ETNA) is characterized by a highly productive coastal upwelling system and a moderate oxygen minimum zone. The recent discovery of re-occurring mesoscale eddies with close to anoxic O2 concentrations located just below the mixed layer has challenged the understanding of O2 distribution and biogeochemical processes in this area. Here, researchers present the first microbial community study from a deoxygenated anticyclonic modewater eddy in the open waters of the ETNA. [Source: Biogeosciences]
