- Prerequisite: Chemistry 1001 or 1031 or 1051 or 2440 or the permission of the instructor and Program Chair
|ENVS 2370 - Global Environmental Change. |
A survey of the Earth as a dynamic system. Discussion of interacting cycles that define the Earth's environment. Material cycles and energy concepts. Evolution of the atmosphere in response to lithospheric, biospheric and hydrospheric changes. Major global environmental changes from Earth's formation to present. Emphasis on self-regulating ability of the Earth system.
- Prerequisite: This course is restricted to students with thirty credit hours or more
|ENVS 3072 - Comparative Marine Environments. |
This course will investigate the physical, chemical, geological and biological characteristics of the major marine environments from the coastal zone to the abyss and from the equator to the poles. The objective of the course will be an integrated study of the parameters that define the various environments. Emphasis will be placed on the interaction of organism and environment. The influence of the environment on the form, function and behaviour or organisms and the influence of the organism in modification of the physical environment will be stressed.
- Prerequisite: Environmental Science 2371
|ENVS 3130 - Freshwater Ecology. |
The study of freshwater ecosystems (lakes, rivers, streams, peatlands). Included are abiotic components, community structures, energy flow, biogeochemical cycles, and the evolution of natural and altered aquatic ecosystems. Emphasis will be placed on field and laboratory studies of the ecology of freshwater organisms and systems in western Newfoundland.
- Prerequisite: Biology 2010, 2122, 2600; one of Chemistry 1001 or 1011
- Lab: Three hours per week
|ENVS 3211 - Environmental Analytical Chemistry II. |
Theory and application of spectroscopic methods of analysis (including error analysis) of environmentally important compounds. Spectrophotometric, FTIR, light scattering, chromatographic (GC, GC/MS, HPLC), fluorescence, phosphorescence, atomic absorption and electroanalytical methods will be studied. Synthetic laboratory samples and field samples will be examined by these techniques.
- Prerequisite: Environmental Science 3210 (or equivalent)
- Note: Lectures and Laboratory: Not more than seven hours per week
|ENVS 3261 - Atmospheric Chemistry. |
Electronic, vibrational and rotational spectroscopy. Rates and mechanisms of gas phase reactions (particularly photochemical). Thermodynamics of the atmosphere. Formation, evolution and structure of the Earth's atmosphere. Chemical and physical properties of the atmospheric gases. Global element cycles. The stratosphere and ozone variability. The iono-sphere. Atmospheric pollutants. Problems of the "greenhouse" gases. Aerosol chemistry. Wet and dry deposition.
- Prerequisite: Chemistry 2300, 2210 or the permission of the instructor and Program Chair
|ENVS 4000 - Environmental Science Seminar. |
Current topics in environmental science are reviewed and discussed in a seminar format. Seminars will be presented on current research and environmental issues by faculty, students and guest speakers from universities, government and industry.
- Prerequisite: "This course is restricted to Environmental Science students who have completed eighty credit hours or more, including Biology 2600, Statistics 2550 and one of the following courses: Chemistry 2440, 2401, 2210 or 2300." Permission of Chair to register.
|ENVS 4133 - Conservation Biology. |
This course will bring together the principles of ecology and conservation biology at an advanced level. Current issues and techniques will be discussed with an aim towards understanding how populations of native flora and fauna can be managed for long-term conservation in the face of habitat degradation and loss.
- Prerequisite: At least two of ENVS 3110, 3130, and 3131; or per-mission of instructor
- Lab: Three-hour laboratory/discussion group per week
- Note: Recommended: ENVS 4132 (formerly Biology 4360)
|ENVS 4249 - Environmental Organic Chemistry. |
Focus on anthropogenic sources of organic chemicals and pollutants in the environment. Concepts of organic chemistry (synthesis, structure, physical properties, chirality, industrial organic processes), biological chemistry (enzymes, oxidative pathways) and physical chemistry (equilibria, partitioning) extended and applied to mass transport through soil, water and air. Kinetics and mechanisms of chemical, photochemical and biological degradation and conversion of organics. Structure-reactivity relationships for organic chemicals and degradation intermediates in the environment.
- Prerequisite: Environmental Science 4240, 3261, 4230 or the permission of the instructor and Program Chair
|ENVS 4950 - Research Project in Environmental Science I. |
With the guidance of a faculty member, students will conduct a scientific study based upon original research or a critical review of extant data in an appropriate area. Students are required to submit a report and give a presentation.
- Prerequisite: Permission of Program Chair
- Note: This project fulfils the Core requirement for a fourth-year individual project in the area of specialization
|ENVS 4959 - Research Project in Environmental Science II. |
This is a continuation of Environmental Science 4951 specifically for Honours students. Under the supervision of faculty member(s), students will carry out an original research project in environmental science. Students will present both a thesis and seminar on their research.
- Prerequisite: Environmental Science 4951
- Note: This course is restricted to honours candidates
