It is equipped with environmental sensors (e.g. pressure, temperature, salinity, chl a) which send data every second, providing a vertical resolution of zooplankton and environmental variables of ~30-40 cm. Images of the LOKI system often allow the identification of fine morphological features, developmental stages, sex and, in some cases, investigation of internal body structures. It uses a flow-through chamber with an upstream plankton net. LOKI operates an industrial camera with up to 6 Mpixels at 15 µs shutter time, combined with a tailored high power LED flash unit to image a volume of approximately 20 x 20 x 5 mm^3 in a flow-through chamber."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL1586" ; skos:note "accepted"@en ; skos:prefLabel "iSiTEC Lightframe On-sight Keyspecies Investigation {LOKI} imaging sensor - Schulz et al.
