OCG 301 Study Guide - Final Guide: Chlorophyll Fluorescence, Redfield Ratio, Upwelling
Document Summary
What regulates the distribution of nutrients in the oceans. Iron is limiting phytoplankton growth, more iron would cause more production. Hypothesis; by adding iron you can increase the biological production. If we dump iron, that will stimulate biological productivity that will sink to the deep ocean. Sample the ocean at any given place, you would approx. Whatever has the smallest amounts is the limiting (liebig law of minium) Deepwater formation in the na, older the water the higher concentration of nutrients. Idea that colder water can hold more nutrients than warmer water. Deep water has a lot of nutrients, upwelling will have high nutrient concentration in the surface water. Different constituents in the water impact the color. Greener the water, higher concentration of chlorophyll. Shifting from blue to green as you add more chlorophyll. Energy converting co2 to oxygen, lose some energy to heat and fluorescence. Absorb blue and absorb red (why water is green with alot of phytoplankton)
