This technique leverages the density-dependent nature of viral infection, preventing new infections by dilution. Samples were collected via ROV SuBastian, sequentially filtered to remove larger particles, and concentrated using tangential-flow filtration. Duplicate incubations were set up with prokaryotic concentrate and virus-free water, pressurized to 250 bar, and incubated in the dark at in situ temperatures for 30 hours. Subsamples were taken every six hours for enumeration of prokaryotes and viruses via flow cytometry. Parallel experiments were conducted at surface pressure to assess the impact of pressure on virus production rates. The methodology ensures observed increases in viral abundance are due to pre-existing infections. The experiments were conducted aboard R/V Falkor(too) between 5-22 July 2023 by Tinkara Tinta and Nicole Krause. Prokaryotes and viruses were enumerated flow-cytometrically back in the lab by Christian Winter.\n\ncdm_data_type = Other\nVARIABLES:\ndive (unitlesss)\nsample_id (unitlesss)\nsubsample_id (unitlesss)\nhabitat (unitlesss)\nlatitude (degrees_north)\nlongitude (degrees_east)\ndepth (m)\ntemperature (degrees Celsius (degC))\nincubated_at_250bar (unitless)\ndate_local (unitless)\ntime_local (unitless)\ntime (Iso_datetime_utc, seconds since 1970-01-01T00:00:00Z)\nprokaryotes (Nx10^4 mL^-1)\nviruses (Nx10^4 mL^-1)\n | https://erddap.bco-dmo.org/erddap/metadata/fgdc/xml/bcodmo_dataset_936224_v1_fgdc.xml | https://erddap.bco-dmo.org/erddap/metadata/iso19115/xml/bcodmo_dataset_936224_v1_iso19115.xml | https://erddap.bco-dmo.org/erddap/info/bcodmo_dataset_936224_v1/index.htmlTable | https://www.bco-dmo.org/dataset/936224
