Identification of zones of preferential groundwater tracer transport using a mobile downhole fluorometer [PDF]

open access: yes, 2018
A mobile downhole fluorometer was used to detect zones of preferential groundwater tracer transport into an observation well. Identification of such zones is not possible if individual samples are collected over the well's entire screened interval ...

Coral photobiology studied with a new imaging pulse amplitude modulated fluorometer

open access: yes, 2005
A new high-resolution imaging fluorometer (Imaging-PAM) was used to identify heterogeneity of photosynthetic activity across the surface of corals. Three species were examined: Acropora nobilis Dana (branching), Goniastrea australiensis Edwards A Haime

Measurement of phytoplankton photosynthesis rate using a pump-and-probe fluorometer

open access: yesOceanologia, 2001
In this work we have studied the possibility of determining the rate of phytoplankton photosynthesis in situ using a submersible pump-and-probe fluorometer in water areas differing in their trophic level, as well as in climatic and hydrophysical ...

Portable cyanobacteria detection fluorometer with current-conveyor transimpedance amplifiers

open access: yes, 2018
A portable fluorometer has been developed for cyanobacteria detection by exploiting commercially available low-cost photodiodes. Particularly, the front-end detection circuit was integrated on-chip by using a 0.11-mm CMOS process to realize the high ...
