<strong>Climate</strong> Variability and Baltic CodReproductive SuccessWarm temperatures affect reproductive volume:-higher rates <strong>of</strong> biological production andoxygen consumption (metabolism)at higher temperatures-reduced oxygen solubility athigher temperaturesLower salinity could reduce reproductive volume-if salinity < 11 PSU
Exercise 2: <strong>Climate</strong> <strong>Impact</strong>s on Baltic Codin <strong>21st</strong> <strong>Century</strong>-calculate 80-year projections <strong>of</strong> cod biomass under differentexploitation and climate scenarios.To address uncertainty in the salinity projections, conductthe runs using different assumptions <strong>of</strong> salinity decline.-no decline, but random variation-25% decline, with random variation-50% decline, with random variation-for 3 combinations <strong>of</strong> F (0.5, 1, 2)
