Sea primary productivity is an important factor in monitoring the quality of sea waters due to his role in the carbon cycle and the food chain for heterotrophic organisms. Estimation of sea primary productivity may be suspected through the values of chlorophyll-a concentration, but surface chlorophyll-a concentration was only able to explain 30% of the primary productivity of the sea. This concentration in all euphotic zone with sea primary productivity has high correlation, it greater than of surface chlorophyll-a concentration (R 2 = 0.65). Model validation of sea primary productivity has high accuracy with the RMSD value of 0.09 and satellite-derived sea primary productivity were not significantly different. The satellite derived of chlorophyll-a could be calculated into sea primary productivity.

Previous comprehensive investigations of the Canadian Arctic revealed that subsurface chlorophyll maxima (SCM) are widespread and long‐lived structures that can contribute significantly to daily primary production in the water column. However, estimating the annual contribution of SCM to production with in situ or remote‐sensing approaches is challenging in the high Arctic. For this reason and to estimate the impacts of fluctuating or changing environmental conditions on SCM, a numerical approach combining a turbulence model and an ecosystem model was implemented for the coastal Beaufort Sea. An ensemble analysis of simulations suggested that SCM contribute 65–90% of total annual primary production and that this proportion is weakly affected by ice regime, winter nitrogen (N) concentration, parameter values determining phytoplankton growth and decay or the physical forcing imposed, all varying within realistic values. Due to the persistent association between the SCM and the shallow nitracline, the pelagic ecosystem of the coastal Beaufort Sea is apparently characterized by a high ratio of new to total production, contrasting with the common assumption that oligotrophic systems are predominantly supported by recycled N and regenerated production. This study demonstrated that the use of a simple model in combination with in situ data leads to novel insights into biogeochemical processes that are otherwise very difficult to measure and track.

) decreased markedly from west to east, with minima in NO 3 2 and NH 4 1 in surface BS-CB waters, but relatively invariant urea-N concentrations across the entire region. In the BS-CB domain, low uptake rates of nitrate (qNO 32 ) and ammonium (qNH 4 1 ) were exceeded by uptake of urea (qUrea-N). Whereas average qNO 3 2 was highest in the BE-CH domain, qUrea-N was maximal in BB-LS. Average depth-integrated f-ratios ranged from 0.27 in the BS-CB domain to 0.57 in BE-CH, while chlorophyll a (chl a) and primary productivity (qC) were highest in BE-CH and BB-LS, and consistently low in the BS-CB domain. The >5 mm phytoplankton fraction dominated qC and qNO 3 2 in the BE-CH and CAA domains, whereas ESNP and BS-CB were dominated by the <5 mm fraction. In the BB-LS domain, the larger cells were responsible for $50% of qC, qNO 3 2 , and qUrea-N. This study highlights the contrast in ice-corrected average new production between the BE-CH (396 mg C m 22 d 21 ) and BS-CB (5.50 mg C m 22 d 21) domains in summer, and the larger contribution of urea-N uptake to total N uptake in central and eastern regions where NO 3 2 concentrations were lower.
