Description

Eelgrass Climate Impacts
Experimental conditions, growth and survival of eelgrass
PAR Data - Date, PAR
Mean daily values of total integrated irradiance (mol photons m-2 d-1) calculated from 10 minute records.

Methods & Sampling

Photosynthetically Active Radiation data were recorded using a factory calibrated LI-COR LI- 90 quantum irradiance sensors placed above the tanks to characterize the sunlight regime. Data were recorded at 10 minute intervals using a LI-1000 programmable data logger from 18 April to 3 October 2013. Subsequently, data were recorded using the NI data logger and LabView software system used for temperature and pH.

Data Processing Description

PAR - Mean daily values of total integrated irradiance (mol photons m-2 d-1) were calculated from the 10 minute records and provided in this spreadsheet. 10 minute records of the processed data, along with raw data files are available from the PIs, upon request.

Instruments

LI-COR LI-190SA PAR Sensor

Supplied Name: LI-COR LI-190SA PAR

Supplied Description:

Photosynthetically Active Radiation data were recorded using factory calibrated LI-COR LI- 90 quantum irradiance sensors placed at 4 locations around the tanks to characterize the full sunlight regime incident on each tank. Data were recorded at 10 minute intervals using a LI-1000 programmable data logger from 18 April to 3 October 2013. Subsequently, data were recorded using the NI data logger and LabView software system used for temperature and pH. Sensor inter-calibration was performed on site using a series of neutral density filters.

Instrument Type

Generic Name: LI-COR LI-190SA PAR Sensor

Acronym: LI-COR LI-190SA PAR

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0193/

Generic Description:

The LI-190SA Quantum Sensor is used to accurately measure (non-aquatic) Photosynthetically Active Radiation (PAR) in the range of 400-700 nm. Colored glass filters are used to tailor the silicon photodiode response to the desired quantum response. The LI-190SA is also used as a reference sensor for comparison to underwater PAR measured by the LI-192SA or LI-193 Underwater Quantum Sensors.

Parameters

Date and time formats are described in python strftime() syntax.
