Document Summary

The exam will cover the lectures and book readings. Below is a list of topics that are intended to aid you in your studies. Book chapters that you are responsible for are the following: chapter 9, 10, Ocean environments: what are the major parameters affecting the distribution of marine organisms? (i. e. salinity, light, temperature, dissolved oxygen, pressure, desiccation, ph, water movement) Latitude has a strong effect on temperature, salinity and insolation. Temperature strong influence of latitude: seasonal variation at mid-latitudes, thermoclines at mid and lower latitudes, most important for oceanic organisms- cold-blooded which means body temperature near temperature of water they live in. Pressure at sea level 1 atm= 14. 7 psi: every 10 m of depth increase by 1 atm ex. 100 m= 11 atm (100/10+1: gas bladders control buoyancy and fish body tissue filled with fluid. Dissolved oxygen: solubility of gases decreases as salinity increases, solubility of gases decreases as temperature increases, solubility of gases increases as pressure increases.
