GEOS 1001 (3CR)
INTRODUCTORY OCEANOGRAPHY
A study of the oceans and their relationship to our land environment. An inter-disciplinary approach is emphasized, including geological, physical, chemical and biological aspects of offshore and deep-water oceanography. Topics include: history of oceanography, exploration techniques, instruments and vessels, structure of Earth, origin of oceans and ocean basins, physiography of ocean basins, marine sediments, submarine volcanism, waves, tides, ocean currents, climatology and sea level changes, marine ecology and marine resources. Three lectures and one 3-hour laboratory per week.
Prereq: None.

GEOS 1011 (3CR)
DYNAMICS OF THE EARTH
(An Introduction to Physical Geoscience) An introductory course in Physical Geoscience which provides a basis for further courses in Geoscience. Main topics of study are the origin, evolution and structure of the Earth; the origin and dynamics of ocean basins, continents and mountain ranges are dealt with in a consideration of plate tectonics; organization of matter - into minerals, crystals and gems; the nature and distribution of sedimentary, igneous and metamorphic rocks; the work of water and ice and air in erosion and the transportation of sediment. Three lectures and one 3-hour laboratory per week.
Prereq: None.

GEOS 1021 (3CR)
EARTH HISTORY
(The Record of Global Change & Life on Earth) An introductory half course in Historical Geoscience which emphasizes the geological evolution of the earth as well as its plants and animals. This half course is complementary to Geoscience 1011 and ideally should be taken after completion of the half course of Physical Geoscience. However, it can be taken independently. The principles of Stratigraphy (historical Geoscience) and Palaeontology (the study of ancient life through fossils) are covered briefly as well as various aspects of Paleogeography, Paleoclimatology, Paleoecology and the Evolution and Extinction of life. Palaeontological and stratigraphic evidence for "Continental Drift" is presented and the interrelationship of the concepts of Continental Drift, Ocean Floor Spreading, and Plate Tectonics is covered along with their historical development. The record of "global change" in climate, faunal and floral distribution and the distribution of present and past continents and oceans is covered. The historical development of the Geological Time Scale or Time Order Scale and its calibration is an integral part of the course. Three lectures and one 3-hour laboratory period per week.
Prereq: None, but GEOS 1011 is highly recommended.

GEOS 2031 (3CR)
GLOBAL ENVIRONMENTAL CHANGE
(Perspectives on Environmental Geoscience) An introductory level course dealing with the interactions of the environment and the Earth - particularly those aspects of the environment influenced by civilization and vice versa. The course gives an overview of major natural processes and geologic hazards which influence civilization, with detailed consideration of natural flooding, landslides, coastal processes and erosion, earthquakes and volcanoes as well as hydro Geoscience and groundwater. It also deals with the effect of civilization on the physical environment - particularly on surficial deposits and near surface crystal rocks or bedrock e.g. the contamination of groundwater and surface waters by waste disposal (including nuclear waste); Acid Rain, Radon gas and the "Greenhouse Effect." Three lectures and one 3-hour laboratory period per week.
Prereq: Any 1000 level Geoscience course; or permission of the Department.

GEOS 2101 (3CR)
COASTAL OCEANOGRAPHY
A 2000 level three unit course complementary to Geoscience 1001 (Introductory Oceanography) in which the focus is the offshore and deep sea oceanography. The course emphasizes North American Atlantic coastal and near shore environments and the interactions among chemical, geological, physical and biological phenomena. Included are methods of study, estuarine systems, sediment regimes, waves, beaches, tides, marshes, deltas, rocky shores, mudflats, barrier islands, reefs and coastal classifications. Special attention is given to sea level changes, erosion and pollution problems.
Prereq: GEOS 1001; or permission of the Department.

GEOS 2401 (3CR)
GEOMORPHOLOGY
Geomorphology is the science that explores the general configuration of the Earth's surface. It deals with the description, classification, nature, origin, and development of present landforms and their relationships to underlying geological structures and the history of geologic events recorded by these surface features. A thorough appreciation of Geomorphology is essential to anyone engaged in Environmental Geoscience. The introductory part of the course deals with the large-scale relief features of the earth (e.g., mountains) and how they are shaped by the processes of weathering, erosion, and sedimentary deposition. The latter part of the course introduces the types of landforms/landscapes that exist in glacial, fluvial, coastal, and desert environments and explores the geomorphic agents (e.g., running water) which control the formation and evolution of these landforms/landscapes.
Prereq: Any 1000 level Geoscience course; or permission of the Department.

GEOS 2501 (3CR)
HYDROGEOLOGY
This course introduces the student to the science that deals with subsurface waters (groundwater) and with related geological aspects of surface water hydrology. The course will deal with hydrogeologic principles as well as concepts and processes that control the occurrence, movement, storage and chemical character of groundwater. It will also describe the basic relation of hydrogeology to other sub-disciplines of Geoscience such as geomorphology, stratigraphy and structure and will deal briefly with problems of groundwater pollution resulting from waste disposal and salt-water intrusion and contamination in coastal areas.
Prereq: GEOS 1011 and 2401; or permission of the Department.

GEOS 3111 (3CR)
COASTAL GEOMORPHOLOGY
This lecture, laboratory, and field course introduces coastal geomorphology by emphasizing current theories of coastal processes set in the context of natural systems.
Prereq: GEOS 2401; or permission of the Department.

GEOS 4950 (6CR)
SPECIAL TOPICS IN GEOSCIENCE
A course to permit an advanced student to pursue a special field of study, or to take advantage of a different approach under the direction of an appropriate staff member. Each student's programme will be planned individually using lectures, reading, tutorials, laboratory work, etc.
Prereq: Permission of the Department. Each student must obtain, prior to registration, consent of a staff member who is willing to supervise his/her work.

GEOS 4951 (3CR)
SPECIAL TOPICS IN GEOSCIENCE
Up to two of these three credit courses (all similar to 4950) may be taken in lieu of Geoscience 4950 . The same regulations apply to them as to Geoscience 4950 .
