Document Summary
13 life in the ocean: marine biology the study of marine organisms. Biological oceanography study of relationships between marine organisms and marine environments. Solubility of gases in seawater decrease as temperature increases. Organic compounds contain carbon, hydrogen, oxygen, and energy. Takes energy to make, yields energy when broken apart. Nutrients materials other than carbon, hydrogen, and oxygen needed to make organic compounds: major ones: nitrogen, phosphorus, sulfur, micro-nutrients, vitamins, etc. Nitrogen must be fixed to be available to organisms. Carbon cycle is earth"s largest cycle: mostly found near coastal regions and in upwelling zones. Redfield ratios determination of molecular productivity that is based on what is least abundant. Biological pump combined biological processes which transfer organic matter and associated elements to depth. Surface to volume ratio r cubed (volume) divided by r squared (surface area) = r. Ability to get nutrients is proportional to surface area (r squared) Amount of nutrient is proportional to its volume (r cubed)
