The growth rate of phytoplankton will also be measured by daily counting to assess the development at exponential and stationary growth phases. The final phytoplankton C:Chl ratio will be estimated [...] NPZD model (Nutrient-Phytoplankton-Zooplankton-Detritus) created by Anderson et al. (2015).

Species from more southerly [...] water, ice thickness, water mass movement and biological data on the activity of ice algae and phytoplankton during winter months are crucial to better understand the physical and biogeochemical processes [...] velocity distribution, temperature, salinity, and stratification. Ice-algae and free floating phytoplankton produce enormous amounts of biomass. Reduced sea ice cover and sea ice thickness could change
