Details

The miniPAR logger is a portable, submersible instrument for measuring diffused sunlight through water, or PAR (Photosynthetically Active Radiation). The miniPAR also contains a tilt sensor to ensure proper orientation, as well as a temperature sensor. Data are 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.

The miniPAR is fitted with a 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.

The miniPAR is internally powered by 2 user-replaceable AA batteries. At a sampling interval of one minute, PME is confident that the logger can continue collecting measurements for over one year before the batteries need to be replaced. For long deployments, PME recommends use of an anti-fouling miniWIPER, which protects data accuracy by cleaning the sensor at regular intervals. The miniPAR is constructed from strong Delrin plastic that does not easily crack or break.

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 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 easily read PAR measurements and allows the user to set the internal clock and sample rate.

Buttonbush Swamps, Bald Eagles, Soras and More: Ashland University’s Black Fork River Wetlands Environmental Studies Center Showcases Wetlands Wildlife and Habitats

Growing from a 38-acre purchase in 1998 to 298 acres in 2004 to the 305 acres it encompasses today; the Black Fork River Wetlands features habitats not found just anywhere, including buttonbush swamp, swamp forest, marsh, riparian corridor and uplands habitats. Beavers make their homes there, as well as trumpeter swans, bald eagles, soras and sandhill cranes. While it may seem picturesque and undisturbed, it is in fact embattled due to human activity on all sides. “It’s a multi-use area,” says Jenna Binder, a visiting Assistant Professor in Ashland University’s Biology and Toxicology Department. “It’s strongly influenced by the heavy agriculture in this area of Ohio. Oil and gas industry fracking is also being done in the area.

AS IF: North Carolina Biological Station Inspires Researchers and Artists to New Heights

Biological field stations make it possible for researchers all over the country to conduct environmental research. While some field stations have artist residencies, art is typically not the main focus of the biological station. Not so at Bakersville, North Carolina’s new AS IF Center (Art + Science In The Field) , which just opened its doors in March 2018. At AS IF, researchers and artists are deliberately invited to commingle, collaborate and create new things together. Far from being on the periphery or existing as an afterthought, artists are considered to be on parity with researchers at AS IF, the one energized by the other’s perspective.

Floating, Diving Robots in the Southern Ocean

The polar regions of the world have always a challenge for scientists to explore and study. Even logistics that are typically no more than passing concerns under other circumstances such as transportation become major problems during polar wintertime. Now, r esearchers are reporting on their use of hundreds of oceanic floats that are drifting and diving their way through the Southern Ocean, including under its ice, with surprising results. Happy robotic wanderers EM spoke with Dr. Alison Gray , assistant professor of physical oceanography at the University of Washington , to find out more about the work, the robots, and the significance of the findings in improving our understanding of the global climate and this poorly studied region.
