The water samples for the incubation experiment were collected on the RV Polarstern at the LTER HAUSGARTEN 79N and -5 W to 11 E on 31 May and 21 June 2021. The parameters include inorganic nutrients, oxygen, oxygen respiration, INT reduction, primary production (PP), bacterial production (BP), prokaryote and viral abundance. Inorganic nutrients include nitrate, nitrite, siliate, and phosphorus. Oxygen and oxygen respiration were analyzed using Winkler titration. INT reduction is the in vivo Iodo-Nitro-Tetrazolium (INT) salt reduction. PP was determined on board the ship using the 14C-incorporation method and BP was measured using 3h-leucine and the microcentrifuge method. Bacteria and viral abundance were measured on a flow cytometer (Cytoflex, Beckman Coulter, USA). The purpose of data collection was to understand the rates of phytoplankton and bacteria across the Fram Strait.
