©2020 Biological and Chemical Oceanography Data Management Office.The Automatic Laser Fluorometric Analyzer (ALFA) is a state-of-the-art instrument, that combines high-resolution spectral measurements of blue (405 nm) and green (532 nm) laser-stimulated fluorescence, with spectral deconvolution techniques to estimate CDOM, phytoplankton variable fluorescence (Fv/Fm), Chl a and three types of phycobiliprotein pigments. This data was collected using the ALFA in Underway fluorescence mode and sampling in the western Eastern Indian Ocean Upwelling region on the ...

Underway fluoresence sampling from the western Eastern Indian Ocean Upwelling region on the R/V Roger Ravelle in January - March 2022 (BLOOFINZ). See RR2201 cruise report in related publications.
When the instrument is used for underway sampling, the ALF is connected to the ship’s uncontaminated seawater flow-through system allowing for continuous measurements in water drawn from approximately 5m below the surface.
