Bu dersin amacı, değişik göl tiplerinin jeolojisi ve jeomorfolojik evrimi, çökel süreçleri, ekolojisi ve bu ekolojinin zaman içerisinde doğal ve insan eliyle değişimi ve limnoloji çalışmalarının iklim değişimi, tektonizma ve jeolojik çevre koşullarını saptamada önemini anlatmaktır.

İçerik

Genel limnoloji ve tatlı su sistemleri; göllerde ışık ve ısı, su hareketleri; göllerin ekosistemleri, yiyecek zinciri ve canlı populasyonları; sedimanter süreçler ve çökel türleri, göllerde uzun ve orta vadeli deniz düzeyi, iklim ve tektonik değişimlerin kayıtları; kısa süreli değişimler; su kaynağı olarak göller.

Contents

1.        Study of limnology and freshwater resources, geomorphology and morphology of lacustrine basins, lake classification schemes: by trophic state and stratification behavior, and by geomorpholgy.

2.         Light and heat: energy transfers in water, effects of snow & ice, transparency, color, heat budgets

3.        Water movement: hydrodynamics, hydraulic movement, wind, tides & currents and circulation. Seasonal changes: turnover, stratification, oxygenation and oxygen profiles, nutrient cycles, freezing

4.        Lacustrine ecosystems; riverine systems and drainage basins, oxygenation, nutrient cycling; lake zones by depth, by light penetration, by faunal type; trophic and ecological characteristics, food web, fauna.

5.        Population growth and regulation, community structure and interrelationships, nutrient cycles.

6.        Natural change: evolution of the lake, salinization, eutrophication, seasonal succession, disturbance effects, predation, competition, fish, carbon cycling.

7.        Out-of-balance ecology: invasive species dynamics, toxic algal blooms.

8.         Sedimentary processes: River and lake-forming processes, sediment transport, beach formation and redeposition, turbidites, cohesion factors, entrainment.

9.        Sediment deposition – currents, roughness, landscape disturbances, mixing depth, oxygenation of the bottom water, picnoclines, haloclines and thermoclines, alkalinity. Diagenesis and post-depositional changes.Unique lake sedimenatry features: stromatolites, tufas, varves, travertines, black mats.

10.      Sediment composition: autochthonous and allochtonous sedimentation, CaCO3, marls, diatoms, gyttja, oligotrophic, clays – links between life activity in the lake and sediment type; detritus and productivity.

11.      Watershed processes: soil and vegetation influences on lakes, sedimentation rates, bedrock influences, disturbance events and their affects.

12.      Long and intermediate time-scale records - sea-level, tectonism, climate change

13.      Short time-scale records - environmental studies: acid rain, nutrient pollution, heavy metal pollution, fire and flood history, earthquake, volcanic events, hurricane frequency

14.      Water resources – water quality, water budgets for countries, regions, cities, manmade and natural disasters.
