چکیده
1) Comment: General Comments: The manuscript presents an extensive analysis of 13C, NO3 and NH4 -uptake versus irradiance experiments for the Arctic subsurface chlorophyll maxima (SCM). NO3 and NH4 – uptake versus irradiance experiments are rarely conducted alongside traditional “P vs E” curves, so the paper includes some novel information on the rates of NO3 and NH4 uptake compared to carbon fixation for a range of irradiances and locations in the Canadian Arctic. Some observations, such as variability in the f-ratio with light and nitrogen availability, have wider implications for ocean biogeochemistry, but on the whole the paper is of local interest. My main

Interactive comment on “Nutritive and photosynthetic ecology of subsurface chlorophyll maxima in the Canadian Arctic waters” by J. Martin et al
This manuscript assumes that subsurface chlorophyll maxima (SCM) in the Canadian Arctic waters have a large role in new production in the water columns, and reports nutritive and photosynthetic characteristics of the SCM. However, vertical maximum of nitrate uptake rate does not occur at SCM in oligotrophic tropical and subtropical oceans (e.g. Raimbault et al., 1999; Aufdenkampe et al., 2002; ...
