Possible mechanisms include (iv) fertilization of phytoplankton growth in the Southern Ocean by increased deposition of iron - containing dust from the atmosphere after being carried by winds from colder, drier continental areas, and a subsequent redistribution of limiting nutrients; (v) an increase in the
whole ocean nutrient content (e.g., through input of material exposed on
shelves or nitrogen fixation); and (vi) an increase in the ratio between carbon and other nutrients assimilated in organic material, resulting in a higher carbon export per
unit of limiting nutrient exported.
Of course, not every house comes complete with an open - plan kitchen, but adding recessed storage, open
shelving units, and extra light can do a lot to make a cramped space feel more inviting for the
whole family.
