Bodies of Freshwater.
limnologists
Limnologists study freshwater systems such as lakes, rivers, and wetlands. They focus on the physical, chemical, biological, and ecological aspects of these environments to better understand their functioning and how they are affected by human activities and natural processes. Limnologists play a key role in conservation efforts and water resource management.
Limnologists study freshwater ecosystems, including lakes, rivers, ponds, and wetlands. Their research focuses on the physical, chemical, biological, and ecological characteristics of these water bodies, examining factors such as water quality, aquatic life, and the impacts of human activity. They often investigate issues like pollution, habitat restoration, and the effects of climate change on freshwater systems. Limnologists contribute valuable insights for conservation and management of water resources.

People who study water are often referred to as hydrologists, limnologists, or water resource engineers, depending on their specific area of focus within the field of water science.

A limnologist is a scientist who studies the lake environment.
They study it and record it.
Examine or Study would both suffice
investigate, study, planning, scientific
they investigate,predict,observe, and at last they hypothesis.
An advantage of using a correlational study is that it allows you to investigate variables that cannot be directly manipulated.
