The Great Lakes are in a state of rapid and continuous change resulting from a host of environmental and anthropogenic stressors. Such circumstances require unique, targeted monitoring solutions to meet environmental demands and continuously document these changes. Hayden Henderson, a research engineer with the Great Lakes Research Center (GLRC), designs such systems, working with research […]
Syracuse, New York, is home to a number of urban creeks, ideal for monitoring the influence of human development on water resources. Syracuse University (SU) faculty, staff, and students have been monitoring the city’s waterways for over a decade, with Dr. Laura Lautz establishing a more formal program focused on collecting grab water samples from […]
The YSI EXO Multiparameter Sondes can simultaneously measure multiple water quality parameters, including conductivity, temperature, pressure, dissolved oxygen, and many more. It easily integrates with NexSens X-Series data loggers using the SDI-12 sensor interface. Sensor Setup Before the sensor can be deployed, it must first be set up through KOR software. For proper communication with […]
Lake Lugano (Ceresio) and Lake Maggiore (Verbano) comprise a significant portion of territory in Ticino, located in southern Switzerland. They are crucial to the region’s biodiversity, society, and economy. In addition to being important for ecological and tourism purposes, the lakes provide drinking water for a significant portion of the population. Recognizing the lack of […]
Oxidation-Reduction Potential (ORP), also known as Redox Potential, is a measure of water’s ability to facilitate chemical processes that either oxidize or reduce substances within it. It indicates the presence and activity of agents that can accept or donate electrons. ORP is measured in terms of electric potential with standard units of millivolts (mV). Readings […]
pH has a complex role in water chemistry as it influences the solubility, reactivity, and potential toxicity of a wide range of elements commonly found in water.
Turbidity is the state of relative clarity or cloudiness of water. Many factors can contribute to increased turbidity. The most obvious are suspended sediments consisting of various sand, silt, clay and gravel particles. These may be introduced by soil erosion, urban runoff, bottom-dwelling aquatic creatures that stir up settled sediments, or human activities such as […]
Dissolved oxygen, often abbreviated as DO, is the amount of free oxygen molecules (O2) dissolved in water. Oxygen enters the water through atmospheric diffusion, plant photosynthesis, or aeration (either natural or man-made). DO is typically represented in measurement units as percent of air saturation (%sat) and concentration in milligrams per liter (mg/L) or parts per […]
Conductivity, often denoted as EC (electrical conductivity), is a measure of a water sample’s ability to conduct electric current. It is primarily determined by the presence of dissolved salts and other inorganic substances that ionize in water. Such substances are known as electrolytes, and they conduct electricity due to their positive and negative charges. The […]
