Description

Photosynthetically active radiation (PAR; mmol photons m-2 s-1) was recorded with a LI-COR underwater spherical quantum sensor (LI-193) and datalogger (LI-1400) situated in the middle of the fiberglass tank during each of the stable isotope labeling experiments in June, August, and October.

Instruments

Photosynthetically Available Radiation Sensor

Supplied Name: LI-COR underwater spherical quantum sensor (LI-193) and datalogger (LI-1400)

Supplied Description:

Situated in the middle of a fiberglass tank.

Instrument Type

Generic Name: Photosynthetically Available Radiation Sensor

Acronym: PAR sensor

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/122/

Generic Description:

A PAR sensor measures photosynthetically available (or active) radiation. The sensor measures photon flux density (photons per second per square meter) within the visible wavelength range (typically 400 to 700 nanometers). PAR gives an indication of the total energy available to plants for photosynthesis. This instrument name is used when specific type, make and model are not known.
