NR150 1st Edition Lecture 1 Outline of Current Lecture I Info on Marine Resources II Physical Marine Resources III Energetic Marine Resources IV Biological Marine Resources V Non Extractive Marine Resources Current Lecture I Info on Marine Resources 1 Due to population growth demand for marine resources is going up 2 Human population has grown by 400 in the 20th century 3 We have used more natural resources since 1955 than in all of history 4 currently the exploitation of marine resources is unsustainable II Physical Marine Resources 1 Petroleum and Natural Gas a Most lucrative and valuable resource b Most drilling is done on an offshore platform c A special type of drill is needed for this process d A special transport system is also needed e Extracting these resources is extremely dangerous f Icebergs threaten the rigs used to extract these resources 2 Marine Gravel and Sand a These resources are used to build roads b Second in dollar value only to oil and natural gas c Sea salts are gathered from large evaporation basins d Only 017 of water is liquid fresh and available for use e Desalination will gain in importance as a source of drinking water III Energetic Marine Resources 1 Wind waves currents and tides a These resources can be used to generate power b Fastest growing alternative to oil as an energy source c Unlike oil and natural gas wind cannot be used up d Winds are more steady over the ocean than they are overland therefore making them more effective e The wind is also faster over the sea than it is over land IV Biological Marine Resources 1 Living animals and plants These notes represent a detailed interpretation of the professor s lecture GradeBuddy is best used as a supplement to your own notes not as a substitute a fish and other living creatures are the most valuable biological resource b these resources are not sustainable due to such practices as over fishing c Much of the catch is bycatch d bycatch is a collective word that describes all the animals caught that are not the desired catch V Non Extractive Marine Resources 1 Transport a Transporting of people is cases such as cruise ships or sailboats b Transporting of cargo on cargo ships c Recreation such as fishing or water sports 2 Renewable a Naturally replaced by growth of marine organisms 3 Non Renewable a Once you extract it its gone it does not naturally come back These notes represent a detailed interpretation of the professor s lecture GradeBuddy is best used as a supplement to your own notes not as a substitute
