Chromophoric Dissolved Organic Matter (CDOM)
Chromophoric dissolved organic matter is measured in-situ by using fluorometers to measure the fluorescence of CDOM, which allows scientists to understand the type and quantity in a water body.
Phytoplankton & Chlorophyll
Scientists study phytoplankton due to their positive and negative influences on the natural world, on today's sensor whiteboard, we discuss the ways that phytoplankton is measured as well as cyanobacteria.
Thermal stratification and seasonal mixing are part of a lake's turnover. This event can be monitored using data buoys and temperature strings for a quick look at how a lake changes seasonally and to be on the look out for changes.
Solar radiation is radiant (electromagnetic) energy measured using a photosynthetically active radiation (PAR) sensors that measure upwelling and downwelling solar radiation.
This week on the sensor whiteboard we discuss lake stratification and the methods that scientists employ to monitor these divisions.
Of the many threats our oceans face, the problem of acidification is continuing to be monitored. There are many factors contributing to this issue and scientists are working to remedy the problem.
Turbidity measurements are often used as an indicator of water quality based on clarity and estimated total suspended solids in water.
pH is a measure of the acidity or alkalinity of a solution and is defined as the negative logarithm of the Hydrogen ion and is an important parameter to monitor in water quality measurements.
Dissolved oxygen is an important parameter in assessing water quality because of its influence on the organisms living within a body of water.
Conductivity, Salinity and TDS
An quick lesson on the science and mechanics behind measuring conductivity, salinity, and total dissolved solids.
