Next Generation of Advanced Laser Fluorescence Technology for Characterization of Natural Aquatic Environments.

摘要

The project research addresses our long-term goal to develop the Advanced Laser Fluorescence (ALF) methods and instruments to improve our capacity for characterization of aquatic environments. The ALF technique (Chekalyuk and Hafez 2008, 2013a) uniquely combines spectral and temporal measurements of laser-stimulated emission (LSE) to provide assessments of key variables, including chlorophyll a (Chl), chromophoric dissolved organic matter (CDOM), and phycobiliprotein-containing phytoplankton and cyanobacteria. The measurements of variable fluorescence, Fv/Fm, yield assessments of phytoplankton photophysiological status. ALF measurements in diverse water types have demonstrated its utility for aquatic research and observations. The ALF has been integrated into the major oceanographic programs, including the California Current Ecosystem Long Term Ecological Research (CCE LTER, NSF) and California Cooperative Oceanic Fisheries Investigations (CalCOFI, NOAA).
