Metagenome sequences from deep-sea hydrothermal vent microbial and viral communities collected at International District hydrothermal field, Axial Seamount during 2019, 2021, 2022, and 2023

These data include metagenomes of both viruses and microbes collected during the Ocean Observatories Initiative's Regional Cabled Array (OOI RCA) annual maintenance cruises. Cruises occurred in 2019, 2021, 2022, and 2023. Instruments used included the Particle and Phytoplankton (PPS) DNA sampler deployed at Tiny Towers hydrothermal vent in the International District, as well as the Universal Fluid Obtainer (UFO) fluid sampler mounted aboard ROV Jason. These data assess changes in the microbial and viral community over time at Tiny Towers and at nearby hydrothermal vents, and were collected and processed by Dr. Rika Anderson at Carleton College.
