Overview
The 2009S LI-COR Underwater PAR Sensor Lowering Frame provides support for the placement of two underwater cosine sensors, one each for downwelling or upwelling radiation or a single LI-193SA Spherical Quantum Sensor. The 2009S provides stability for proper orientation of the sensor(s), minimizes shading effects, and features a lower mounting ring for stabilizing weight attachment if necessary.
- Construction: Anodized aluminum
- Size: 51.4 L (20.0") x 35.6 cm W (14.0")
- Weight: 327g (0.72 lbs)

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.

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.

In one history, Whangārei Harbor, nestled in the lush hills of New Zealand’s North Island, gets its name from the Māori, “waiting for the breastbone of the whale.” It seems fitting, then, that it’s now home to state-of-the-art acoustic monitoring buoys listening for marine mammals around the clock. 
 
In September 2024, a team from Auckland-based underwater acoustics firm Cetaware Ltd installed NexSens buoys in Northport, a major commercial port at the entrance to the Whangārei Harbor. 
 
The first buoys to be installed by Cetaware in a permanent setting running 24/7, they use real-time artificial intelligence (AI) models to passively sense Delphinidae–from common dolphins to orcas.
