NR150 1st Edition Lecture 1Outline 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 LectureI. 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 Gasa. Most lucrative and valuable resourceb. Most drilling is done on an offshore platformc. A special type of drill is needed for this processd. A special transport system is also needed e. Extracting these resources is extremely dangerousf. Icebergs threaten the rigs used to extract these resources2. Marine Gravel and Sand a. These resources are used to build roadsb. 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 usee. Desalination will gain in importance as a source of drinking water III. Energetic Marine Resources 1. Wind, waves, currents, and tidesa. These resources can be used to generate powerb. 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 effectivee. The wind is also faster over the sea than it is over land. IV. Biological Marine Resources 1. Living animals and plantsThese 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 resourceb. 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 Resources1. Transport a. Transporting of people is cases such as cruise ships or sailboatsb. Transporting of cargo on cargo shipsc. Recreation such as fishing or water sports2. Renewablea. Naturally replaced by growth of marine organisms3. Non-Renewable a. Once you extract it, its gone; it does not naturally come backThese notes represent a detailed interpretation of the professor’s lecture.
