Details

The LI-COR LI-193 Underwater PAR Sensor gives an added dimension to underwater PAR measurements as it measures photon flux from all directions. This measurement is referred to as Photosynthetic Photon Flux Fluence Rate (PPFFR) or Quantum Scalar Irradiance. This is important, for example, when studying phytoplankton, which utilize radiation from all directions for photosynthesis. The LI-193 features a high sensitivity optical design and compact, rugged construction for use in freshwater or saltwater and pressures up to 493 psi or 350 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.

Plankton Portal enlists public to classify thousands of zooplankton images

Zooplankton drifts through the ocean, often ignored by the public in favor of more charismatic marine organisms farther up the food chain. A new crowdsourced project aims to change that, giving anyone a closer look at small and intricate zooplankton. PlanktonPortal.org features 900,000 high resolution images of zooplankton and tasks the public to identify them as part of data processing for a collaborative study, based out of the University of Miami Rosenstiel School of Marine and Atmospheric Science. Researchers hope the project will tell them more about zooplankton behavior, grouping and interaction.

Maine researchers to study diatoms in Greenland lakes

Researchers from the University of Maine will be studying diatoms in 30 Greenland lakes this summer to understand how the single-celled organisms react to seasonal changes, according to the Polar Field Services Newsletter. The researchers will take their first samples just as the ice melts off the lakes. They will collect a second round of samples during the middle of the summer, when the weather warms up. A monitoring buoy, lent to the researchers from the University of Miami Ohio, will furnish sensors to measure temperature, light, chlorophyll and other water quality parameters. Inflatable boats will be used to access some of Greenland’s remote lakes.

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.
