Details

The LI-COR LI-192 Underwater PAR Sensor accurately measures photosynthetically active radiation (PAR) in freshwater or saltwater environments. Limnologists, oceanographers and biologists conducting aquatic productivity studies and vertical profiling have used these sensors extensively. The LI-192 is cosine corrected and features corrosion resistant, rugged construction for use in freshwater or saltwater and pressures up to 800 psi or 560 meter depths.

The sensor includes built-in voltage outputs for interfacing with NexSens iSIC and SDL data loggers. Sensor cable can be factory-connectorized with NexSens underwater connectors for integration to an SDL submersible data logger sensor port. Data collection options include direct-connect, landline phone, cellular, radio, Ethernet, WI-FI, and satellite telemetry. NexSens iChart Software is a Windows-based program for interfacing both locally (direct-connect) and remotely (through telemetry) to a NexSens data logger or network of data loggers.

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.

Can Better Technologies Save Endangered California Salmon?

Up until the 1800s, salmon were so plentiful in California that these “ bits of silver pulled out of the water ” could be observed ascending the waterways, thousands at a time, each season. However, decades of logging, the construction of dams, and other human interventions have changed the waterways of the state so significantly that the range of the salmon has been permanently altered. Now, a team of scientists collaborating through the Interagency Ecological Program have developed a plan to improve salmon management and, hopefully, help save the species. Team members from NOAA Fisheries, the California Department of Water Resources, the U.S. Fish and Wildlife Service, the California Department of Fish and Wildlife, the U.S. Bureau of Reclamation, and the U.S.

Weather Extremes Shaking Up Fouling Communities in Urban Estuaries

Marine fouling species may seem to be lowly creatures, situated toward the bottom of that portion of the food chain animals comprise. However, these filter-feeding invertebrates that make their homes on hard underwater substrates such as the hulls of ships are among some of the most successful invasive species. Their secret is simply their ability to latch onto human vehicles and survive. Now, new research on the fouling community in the San Francisco Bay indicates that a single wet winter and the change in salinity that high levels of precipitation bring can knock back the advance of these hearty creatures. Marine biologist Andrew Chang of the Smithsonian Environmental Research Center’s Tiburon, California branch published this new research in December of 2017.
