Document Summary
Thought adding iron up into the mix layer, we might be able to stimulate photosynthesis, hope is to sediment organic and inorganic carbon- actual result is the spin just makes it faster does not change net. Blooms increase when temp is optimum for cells, nutrients (cold water= more nutrients), upwelling, high light. Spring has high run off since ice melts, highly concentrated bloom. High productivity with cold water, usually over deep water upwelling (cold water) Mixed and deep layers do not intermingle. Trophic transfers, as individual size increases, total energy retained decreases and total biomass decreases. Niche: a space that an organism can inhabit defined by particular combinations of physical/chemical parameters and resources. Adaptation: specific behaviors or structures that enable organisms to exploit or inhabit a particular niche. Long term reproduction and occupancy of a specific niche defines ecological success.
