Monthly-mean distributions of modeled surface temperature, salinity, nutrient, and terms regulating A. fundyense growth and mortality rates for April, May, June, and July, respectively. Note the July mean is the average of conditions from July 1st to July 15th (the end of model simulation). μ(E,T,S)is the light limited growth, μ(NO3,T,S) is the nutrient limited growth, and μ(E,NO3,T,S) is the overall growth term that is determined by min(μ(E,T,S), μ(NO3,T,S)), according to the principle of Liebig’s Law (Liebig, 1845). The net growth term is [μ(E,NO3,T,S) –mortality]. Units for these biological rates are day−1.
