Shipboard Flow-Through Complex for Measuring Bio-Optical and Hydrological Seawater Characteristics

Abstract

Abstract A flow-through measuring complex has been created for continuous underway measurements of bio-optical characteristics (fluorescence intensities of chlorophyll a and dissolved organic matter, along with the beam attenuation coefficient of seawater) and hydrological quantities (salinity and temperature). Compared to previous versions, the complex measures more characteristics and features wider dynamic range and longer service life. Measurements using the flow-through measuring complex were carried out on several SIO RAS expeditions in various water areas of the World Ocean.
