Freshwater Resources and Limnology

Flashcards focused on key vocabulary and concepts related to freshwater resources, limnology, and lake ecosystems.

Limnology

The study of lakes and inland waters.

Eutrophication

The process of nutrient enrichment in water bodies, leading to increased algal growth and potential oxygen depletion.

Thermocline

A distinct layer in a body of water where the temperature changes rapidly with depth.

Ephemeral

Refers to something that is temporary or short-lived, like lakes which may dry out over time.

Secchi disk

A tool used to measure water clarity and light penetration in lakes.

Trophic status

A classification system for lake ecosystems based on nutrient levels and biological productivity.

Oligotrophic

A state of a lake with low nutrient levels and low algal biomass.

Eutrophic

A state of a lake with high nutrient levels and high algal biomass.

Hypereutrophic

A state of a lake with excessive nutrients and biomass, often leading to severe ecological issues.

Catchment area

The area of land where water drains into a particular body of water, influencing its water chemistry.

Microcystin

A toxic substance produced by certain blue-green algae, such as cyanobacteria.
