LI-COR PAR sensors detect light waves to aid aquatic ecosystem research

Understanding how the sun’s rays fuel phytoplankton or plant growth may prove valuable to understanding an aquatic ecosystem. A pair of sensors from LI-COR can help researchers studying algal blooms and aquatic vegetation by measuring how much light enters underwater environments. Sitting below the surface, the LI-192 flat-lensed photosynthetically active radiation sensor and the LI-193 spherical PAR sensor measure light waves striking their silicon photovoltaic detectors.  They sense light wavelengths between 400 and 700 nanometers, which is the ideal range for photosynthesis. Dave Johnson, a LI-COR product manager for the LI-190 series, said the sensors’ individual designs make them ideal for different applications.

Ohio State greenhouse nurtures 'fruit fly of the plant world'

The Arabidopsis Biological Resource Center at Ohio State University was established in 1991 with funding from the National Science Foundation. Part of the center’s job is to meet demand for seed of the arabidopsis plant, which is widely used for genetic modeling. “A lot of the plants we’re growing are for seed production,†said Joan Leonard, greenhouse coordinator. “Arabidopsis is a good example. We call it the ‘fruit fly of the plant world,’ and it takes about six to eight weeks to go from seed to plant.†Arabidopsis is one of the many plants that will benefit from a new LI-COR PAR sensor being installed on campus. It will help manage light schedules for greenhouse plants.

As Arctic Permafrost Thaws, Northernmost Lakes Brown

More than 250 million years ago, massive volcanic activity in the region of what is now Siberia caused “The Great Dying,†a colorful name for the Permian mass extinction that wiped out most of the life on Earth at the time. Once the volcanic activity finally calmed down after a respectable one million years, about 96 percent of life in the ocean and 80 percent of life on land was gone. About 500 gigatons of carbon were left behind in that region, and as the Earth cooled, that carbon was sealed in the Permafrost that covers much of Siberia today. Permafrost is simply ground that stays frozen at or below 0° Celsius (32° Fahrenheit) all of the time. It does not necessarily contain ice; as long as it remains frozen solid, even completely dry ground is permafrost.
