Overview
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.

Remote Capabilities
The sensor includes built-in voltage outputs for interfacing with NexSens iSIC and SDL data loggers. Sensor cable can be factory-connected with NexSens underwater connectors for integration to an SDL submersible data logger sensor port. 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.

A Happy Oyster is a Happy Tourist: Vester Field Station’s Monitoring Work on the Southwest Florida Coast

A clean environment doesn’t just mean improved biodiversity and fresher air. It also means increased real estate demand. That fact was cemented in 2015 after a Florida Realtor’s report tied hundreds of millions of property values to the Secchi disk depth of the surrounding water. The report was explicit about how important the environment was and how it should be treated as such. “Policymakers and the public would benefit from research into the possible effects of Everglades restoration on water quality in the estuaries of Martin and Lee Counties,” concluded the report.

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.

Lufft WS800: Introducing A Station that Can Weather the Storm

The Lufft WS800 Multi-Parameter Weather Station measures a full suite of atmospheric parameters that provides all-encompassing data on the local environment, including a one-of-a-kind lightning detector. This compact, cost-effective sensor simultaneously measures air temperature, humidity, pressure, precipitation, solar radiation, lightning, and wind with an integrated electronic compass. An internal fan and heater reduce the effects of external influences for accurate measurements during long-term deployments. The sensor can be easily mounted on a 2-inch diameter pipe above any local obstructions with the included bracket mount, U-bolts, and 10-meter cable.  Settings for the unit can be adjusted using the latest UMB-ConfigTool.
