This decrease results because plant respiration also increases with temperature, and some of the photosynthetic gains (that lead to increased productivity) are lost through a) growth and maintenance respiration (Ryan et al. 1995), or b) seasonal differences between photosynthetic gains in the spring and increased respiration in the fall.

Sea ice is critical for polar marine ecosystems in at least two important ways: (1) it provides a habitat for photosynthetic algae and nursery ground for invertebrates and fish during times when the water column does not support phytoplankton growth; and (2) as the ice melts, releasing organisms into the surface water [3], a shallow mixed layer forms which fosters large ice - edge blooms important to the overall productivity of polar seas.
