Courses in Geological Sciences (Division 377)

A. Introductory Courses and Courses for Non-concentrators

G.S. 100-115 are short (half-term) courses. They consist of detailed examinations of restricted geologic topics. The department lists the specific courses from this series in the Time Schedule for the terms they are offered (fall and winter terms only). Each course, when offered, meets twice weekly for half of the term (first half or second half), and the specific dates for each course are printed in the Time Schedule. These courses are designed primarily for students with no prior geologic training and they are open to all interested persons. G.S. 100-115 are offered on the graded pattern (optional pass/fail).

100. Coral Reefs. (1). (NS). (BS).

Coral Reefs will be an in-depth tour of the biological and physical processes active in modern reef systems to provide a detailed understanding of the ecology of the individual organisms and the complex nature of their interactions within the reef community. Evolution of the reef community will be examined, ranging from the crude framework structures formed over one billion years ago by primitive algae to the luxuriant and diversified reefs of the modern-day oceans, to define the evolutionary strategies of reef building organisms. By tracking these evolutionary strategies through geologic time, the implications of man's intervention with the Earth's hydrosphere and atmosphere on the character of future reef communities will be considered. Cost:1 WL:4 (Meyers)

107. Volcanoes and Earthquakes. No credit granted to those who have completed or are enrolled in GS 205, 270, or 271. (1). (NS). (BS).

The course is a study of the earth in action and includes the following topics: geography of earthquakes and volcanoes; catastrophic events in historic times; size and frequency of occurrence of earthquakes and volcanic eruptions; the products of volcanism; volcanic rocks; volcanic activity through geologic time; volcanic exhalations and the evolution of the earth's atmosphere and oceans; relationship of earthquakes and volcanoes to plate tectonics and the internal dynamics of the earth; volcanism and geothermal energy; manmade earthquakes; and earthquake prediction and control. Instruction by lecture, evaluation on basis of final exam.

110. The History of the Oceans. No credit granted to those who have completed or are enrolled in GS 222. (1). (NS). (BS).

The history of past oceanic inhabitants, events, and environments is recorded in the sediments which have accumulated on the ocean bottom throughout geological time. Fossils of marine plants and animals are a major part of the historical record; they give evidence of past oceanic living conditions and the evolution of life forms in the sea. Sediment particles eroded from land and carried to the oceans by rivers and winds provide insights into past climates on continents. Changes in ocean currents and in seawater chemistry have left their mark on the sediment record; the possible causes of these changes are explored. Plate tectonics and seafloor spreading have rearranged the shapes of ocean basins and repositioned continents over time. These processes are reflected in the record in marine sediments still present on the ocean floor and also in those now uplifted to form part of the continents. Selected topics include: the origin and destruction of oceans and mountains, El Ni o events, the Eocene greenhouse, and the origin of life. These topics are presented in lectures held twice weekly for a half term. A single exam at the end of the course will determine the course grade. Cost:1 WL:3 (Owen and Meyers)

111. Climate and Mankind. No credit granted to those who have completed or are enrolled in GS 201 or 275. (1). (NS). (BS).

The intent of this course is to give a heightened awareness to students of the nature and fragility of the Earth's climate, and how changes in climate have affected past civilizations and may affect our future. Course topics will include: a description of the climate systems of the Earth, the atmosphere, oceans, and polar ice caps; the information we gather to understand the history of those systems; how changes in climate have affected past civilizations; and what may happen to the planet if the predicted "Greenhouse Effect Global Warming" finally arrives. Cost:1 WL:4 (O'Neil)

115. Geologic Time. No credit granted to those who have completed or are enrolled in GS 135 or 269. (1). (NS). (BS).

Until the middle of the 18th century the Earth was generally thought to be less than 10,000 years old, and according to many, close to its apocolyptic end. We now know that the Earth formed 4.5 billion years ago and that the entire history of mankind is nothing but the latest tiny fraction of Earth history. The formation of rocks, continental drift, volcanoes, and earthquakes is evaluated in the framework of geologic time and plate tectonics. The discovery of time from the Renaissance to the latest high tech developments in radioactive dating is reviewed. Finally, the history of planet Earth will be described including its accretion out of dust and giant impacts, the origin of the Moon, the formation of the atmosphere and oceans, the development of life and the building of continents. The course will draw upon examples meaningful to the student to illustrate the principles. Lectures twice weekly for half the term. Course pack provides most of the diagrams. A final one hour examination. Cost:1 WL:3/4 (Mukasa)

117. Introduction to Geology. No credit granted to those who have completed or are enrolled in GS 116, 119, or 120. Those with credit for GS 205 may only elect GS 117 for 4 credits. (5). (NS). (BS).

Introduction to Geology is a single term course structured to provide students from all backgrounds with an understanding of the history of Earth and of the natural processes which have given rise to its landscapes, oceans, and continents. This includes examination of: the physical processes which give rise to plate tectonics and the formation of earthquakes, volcanoes, the uplift of major mountain ranges; and of the chemical and biological phenomena which modify the character of the atmosphere-hydrosphere-biosphere at the Earth's surface. This course includes a laboratory to provide hands-on experience in identifying common rocks and minerals and in understanding geological and topographical maps. Topics covered in class lecture are reviewed weekly in a one hour discussion section. Course includes lectures and weekly laboratory and discussion sections. Cost:2 WL:4 (Lohmann)
