چکیده
General comments: This paper investigated the in situ primary production rates and their relation to various environmental variables in the Chukchi Sea including the Russian waters of the Arctic, where only the limited data are available. The authors pointed out that the primary production in the Chukchi Sea is mainly affected by nutrient concentrations and phytoplankton biomass, and the nutrient concentrations, and thus the primary production, are influenced by the freshwater content (FWC). This concept may be not new but seems to be verified from the present data and statistical analyses. In addition, the authors indicated a recent decrease in primary production from decades ago, although the primary production has large temporal and spatial variabilities. The authors suggested that a plausible reason for the recent low primary production could be due to the decreased concentrations of nutrients and chlorophyll. If possible, the authors should show the nutrient and chlorophyll data that are associated with the recent decrease in primary production. This point could be a new finding. This is an interesting paper that is in general clearly written and well-laid out. I recommend the paper for publication in Biogeosciences after some revisions.

متن کاملPrimary production in the Chukchi Sea with potential effects of freshwater content
The in situ primary production rates and various environmental variables were investigated in the Chukchi Sea during the RUSALCA expedition, which was conducted in 2012, to identify the current status of primary production. A C–N dual-tracer technique was used to measure the daily primary production rates, which ranged from 0.02 to 1.61 g C m d (mean±SD= 0.42± 0.52 g C m d). The primary product...
