PME miniPAR Logger
- Submersible up to 100 meters
- PAR, orientation, and temperature sensors
- Anti-fouling wiper available
The PME minPAR contains a tilt sensor to ensure proper orientation and a temperature sensor. Data is recorded on an internal SD card. The miniPAR is powered by 2 AA batteries and can be fitted with an anti-fouling miniWIPER to protect long-term data accuracy.
Measuring Photosynthetically Active Radiation
The miniPAR is fitted with an LI-192 Underwater Quantum Sensor manufactured by LI-COR. The sensor uses a silicon photodiode and glass optical filters to create a uniform sensitivity to light wavelengths in the 400-700nm range. It measures PAR from all angles in one hemisphere. PAR is a key indicator for understanding nutrient loading, photosynthesis, algae blooms, or other biological, chemical, or physical processes.
PME is confident that the logger can continue collecting measurements for over one year before the batteries need to be replaced at a sampling interval of one minute. The miniPAR is constructed from strong Delrin plastic that does not easily crack or break.
Embedded Tilt Sensor
The miniPAR is unique among similar loggers in that it contains a tilt sensor to measure the orientation of the device. Since PAR measurement accuracy is dependent upon the sensor being pointed toward the water surface, the tilt sensor will alert the user if the sensor is rotated in a particular direction.
PME Software Included
PME software is provided with every miniPAR logger and can be found on the included SD card when it is connected to a computer. The software creates visual plots to read PAR measurements easily and allows the user to set the internal clock and sample rate.
In The News
The value of multi-lake studies is well understood by international organizations like the Global Lake Ecological Observatory Network (GLEON) and the scientists who work tirelessly to provide data to the larger network. Rebecca North, an associate professor at the University of Missouri-Columbia , is one of many researchers involved in multi-lake research initiatives and conducting research locally in her home state.
Having been born and raised on the shore of Lake Ontario, North grew up in a community that revolved around water. She also saw firsthand one of the worst water quality bodies of the world, the Bay of Quinte, decline throughout her lifetime.Read More
It is no secret that in today's world, most scientists do not stick exclusively to science–they must be educators, communicators, and advocates. The looming threats facing the planet's climate and the growing distrust in science by the public have forced scientists to expand and improve their capacity for science communication to the world.
From repeatedly testifying before the U.S. Congress to winning an Emmy as the Chief Scientific Advisor for an award-winning nature documentary, marine ecologist James W. Porter has been thrust into the public eye.Read More
Historically, water quality monitoring during the winter has been difficult and often avoided altogether—however, monitoring throughout the year can highlight the influence of various environmental stressors and track the changes systems undergo during the winter. In particular, long-term monitoring efforts in systems like Mohonk Lake can underline the effects of climate change and acid rain.
David Richardson, a professor of biology at the State University of New York (SUNY) at New Paltz , spends his time outside of the classroom monitoring the nearby watersheds. After getting his engineering undergraduate degree, Richardson realized he wasn't interested in the typical job offerings and applied to an ecological science graduate program at the University of Maryland.Read More
