This is an SOP of "A Protocol for Monitoring Estuarine Nutrient Enrichment in Coastal Parks of the National Park Service Northeast Region" (https://irma.nps.gov/App/Reference/Profile/2218712). Goodman 1993, Moore et al. 1997).Post-Deployment Calibration Check. Photosythetic photon flux density (PPFD) is a highly erratic variable, so a certain degree of time averaging is necessary in order to smooth the data. This SOP calls for 15 second averaging of irradiance at each depth in the profile. It also calls for irradiance at depth to be reported as a percentage of the instantaneous irradiance in air. This latter step corrects for any error that would be introduced by changes in the incident solar irradiance over the period of time it takes to complete a full profile of the water column. The purpose of this SOP is to standardize instrument programming, assembly, calibration, and use throughout the NER coastal parks. It provides step-by-step instructions as they pertain specifically to this monitoring protocol. It is outside the scope of this SOP to comprehensively review all of the information and methods that are required to operate these LiCor instruments and to make effective and accurate measurements. It is imperative that both field and laboratory personnel familiarize themselves with the LiCor LI-1400 Datalogger Instruction Manual and the LiCor Radiation Sensors Instruction Manual (for both the terrestrial and underwater type SA sensors). Although the LI-1400 has data logging capabilities, data are recorded manually in this protocol. The LI-1400 serves here as an easily programmable controller and display interface for the PAR sensors and performs some simple calculations and data averaging functions. It is possible to use the logging function as well, but the nature of the data from this SOP make manual logging more expedient.
