“A tale of two oceans: Nitrogen dynamics at the Hawaii and Bermuda Time-series Stations” The ocean's harbor a dizzying diversity of microbial life. One class of surface-dwelling ocean life forms, called diazotrophs, are able to fix nitrogen out of thin air, metaphorically speaking. These are essentially the cover crops of the ocean; they are capable of adding 'new' nitrogen to the upper ocean that can fuel carbon export into the mesopelagic. This talk will cover what we know about these organisms and the controls of their activity at the sentinel time-series station of the North Pacific subtropical gyre: Station ALOHA. For additional context, the findings will be compared with findings regarding nitrogen fixation and related nitrogen cycle processes in the subtropical North Atlantic.
