GEOL 5530 - Physical Limnology
Physical parameters and processes in lake environments, including temperature, light, heat, oxygen, alkalinity, and dissolved ions. Labs include outdoor sampling and measurements.
Credit Hours: 4
Repeat/Retake Information: May not be retaken.
Lecture/Lab Hours: 2.0 lecture, 2.0 laboratory
Grades: Eligible Grades: A-F,WP,WF,WN,FN,AU,I
- Ten percent of the final grade is based on extra work. This involves an extra lab exercise which involves a computation of the respiration of a lake while balancing oxygen, carbon dioxide, and ammonia production ( like a Tier III capstone exercise).
- Graduate students are expected to perform better than their undergraduate counterparts and actually help the undergraduates as they work through labs together.
- Learn about the seasonal changes of lakes and the recycling of ions and compounds from lake water to sediments and back.
- Learn field skills in collecting data on a nearby lake.
- Learn how to calculate lake parameters such as lake morphometric indices, light transmission, heat budget, alkalinity, carbon dioxide and oxygen budgets, and lake respiration.
- Learn how to construct maps and time diagrams of lake water cross-sections through the use of the program Surfer.
- Learn the basic techniques in the analysis of lake basins and their waters, including lake morphometry, physical and chemical measurements of a lake water column using a sonde, and laboratory reconstruction of lake stratification and seasonal turnover.
