The study of salt waters found in oceans and seas are referred to as marine study while the study of fresh waters are referred to as aquatic studies. Study of aquatic systems examines two broad areas: the first addresses amounts and locations of water (hydrology) and the second topic deals with water quality. The following field studies address some aspects of these broad topics. Ground water and aquifers are not described, but springs and surface water flows as well as lakes and ponds are the focus of these field studies.
Hydrology is the study of water on the landscape. This includes river and stream flows and lake volumes. The central aspect of hydrology is the global circulation of water through different pathways and at different rates click image for additional information
Water quality refers to the physical, chemical and biological aspects of water. The quality of water refers to the condition of water compared to the requirements of one or more biotic species and human needs. It is most frequently used by reference to a set of standards against which compliance can be assessed. The most common standards used to assess water quality relate to health of ecosystems, safety to humans. Click image for additional information
